Advantages and applications of touch screens for B2B and B2C

The touch screen is a convenient way for a user to interact with a computer interface. The product is made in the form of a flat panel made of transparent plastic alloy or natural glass. Inside are electronic components, a variety of which differs from a specific type of sensor. On the side is a loop designed to connect to computer equipment and transmit signals for managing information content.


Today, touch screens are used in various areas of life. Most often, such devices are found in ATMs, interactive advertising stands and payment terminals. Also, home use occurs when the owner of a conventional computer wants to add a touch control function. This feature is especially relevant for illustrators and artists. Thanks to the touch screen, managing the graphic editor becomes much more comfortable.

Variety of sensors

A very common technology used in touchscreens is “resistive covering” – see details. It is a transparent film in which small insulators are mounted. When the user presses, the computer processor registers the location of the current leak. The advantage of the solution is its low cost and the ability to install on any monitor. The main drawback is the need for significant pressure so that the computer records the user’s interaction.

Another technology is called “projected”. This kind of sensors is common in payment terminals. For its implementation, an infrared camera is used that records the thermal radiation of the user’s fingers. The computer processor monitors the movement of the hands and at the moment of contact with the surface of the display registers the press. Such touch screens are distinguished by increased reliability, ease of installation and long-term operation, so they have gained popularity.

Thanks to modern touch-sensitive consoles, you can make any monitor respond to clicks! You just need to determine the type of technology and complete the order


How to choose the right industrial monitor?

Industrial monitors are designed for increased durability and withstand harsh operating conditions in industrial and commercial environments. They are available in various sizes and resolutions, and mounting options are diverse: panel mounting, rack mounting, open frame, etc. Industrial monitor can be touch or not. Touch versions are available as resistive or capacitive panels.


How to choose an industrial monitor?

When choosing an industrial monitor, it is important to consider the conditions and place of its future use. Will it be subject to splashing? The dust? Is high brightness required? The type of installation (rack mounting, panel mounting, etc.) is also important. Which touchpad is more adapted to your application and what degree of protection do you need?

Depending on the working environment and the intended use, you can choose:

  • The size and format of the future monitor. You must define the diagonal (in inches) and the ratio of width to height. The most famous ratios are 6: 9 and 4: 3, but there are also 5: 4 and 16:10 monitors.
  • Monitor resolution. Resolution is the degree of detail in an image, expressed in pixels.
  • Brightness. This is the intensity of the screen illumination. If the screen is not bright enough, you will not see anything in daylight. Brightness is expressed in candelas per square meter. The standard brightness is about 250 cd / m². It should be noted that currently there are ” sun readable monitors “, which are designed for use in very bright conditions. The brightness of these monitors exceeds 1000 cd / m2.
  • Monitor resistance, also called strength. Monitor strength is the resistance of the monitor to aggressive action to prevent short circuits or liquids entering your system. When choosing protection against various types of splashes (water, oils, solvents, etc.), shocks or splashes of more aggressive preparations in hazardous areas, several standards should be followed (see the paragraph on protection standards below).
  • Installing and fixing the monitor. The VESA standard defines standards for mounting monitors: hole sizes, screws used for these holes, and hole configurations on the back of the monitor.
  • Touch function or not. Since the touch monitor is used more and more often, when choosing such a monitor, you will need to study the conditions of use.

Main characteristics:

  • Size and format
  • Resolution
  • Brightness
  • Protection
  • Installation and fixing
  • Touch function or not

What technology to choose for your industrial monitor?

  • LCD monitor (liquid crystal display) uses backlit pixels, providing a standard image, lack of black density and shades of gray. The backlight system makes the LCD monitor wide enough and heavy. The LCD monitor is very energy intensive, but its advantage is that it is affordable.
  • LED monitor is quite widespread in the market. The image is accurate and uniform. LED monitors are illuminated by LEDs. This provides better image quality, better contrast and, in addition, this technology saves about 30% energy compared to LCD monitors. LED monitors are slightly more expensive than LCD monitors, but remain affordable.
  • OLED monitor (Organic LED) offers the best image quality on the market. This monitor uses a chemical that ignites on contact with electric current. It provides the best sharpness and unrivaled color nuances. This monitor is thinner and lighter than other technologies, and consumes less power. However, it is much more expensive.
  • Plasma Monitor: Compared to LCD, Plasma Monitor has better image quality; shades of gray and black are more successful, and the depth is greater. The minimum size of the plasma screen is 107 cm, which makes it quite bulky. It consumes more power than an LCD screen. Since the technology used is relatively old, the price of this type of monitor is low.

How to choose a touch panel for your monitor?

Vecow brand monitor

There are two touch panel technologies:

  • Resistive technology: two conductive layers are separated by an insulating layer. When the user touches the layer, the two conductive films come into contact with each other, which leads to the flow of current. The device will supply voltage, the coordinates of which on the screen will be measured and transmitted to the system. This panel is needed in many applications (GPS, video games, cash registers, electronic diaries, etc.), it is potentially more accurate than the capacitive panel, and responds to any form of pressing. The resistive panel responds to touch with a stylus, gloved hand, bare finger, fingernail, etc. It is resistant to water, grease and dust. On the other hand, the resistive screen is more sensitive to scratches and other damage caused by sharp objects. It is also less reactive than a capacitive screen; its reactivity decreases over time. Finally, resistive panels are less transparent, which leads to a loss of 20 to 25% of the brightness of the screen.
  • Capacitive technology: in this technology, a layer placed on a glass plate accumulates charges. When the user touches the layer with a finger, charges are transferred to it, which creates a measurable interruption of the electrostatic field on the layer. Then the sensors determine the coordinates of the affected area. For multi-touch applications, it is necessary to use panels with projection capacitive technology. They can function with thicker screens. You can also cover the touch panel with a durable armored glass screen. A capacitive monitor has many advantages: it is reliable and scratch resistant, it is also brighter and more transparent than a resistive panel (90% transparency compared to 75% for resistive panels). The sensitivity of the screen is also higher: just touch the touch panel to get an immediate reaction. The disadvantage of capacitive technology is that it does not work when the user uses gloves.

What protection standards exist for your industrial monitor?

Monitor brand Pepperl + Fuchs

The industrial monitor you choose must be optimized for your type of use, and it must also comply with the protection standards applicable to your industry:

  • IPxx Index: the first digit of the IPxx Index indicates protection against solids, the second digit indicates protection against water and/or liquids. Industrial monitors usually have index IP65 or IP67. Finally, you can choose between “Full IPxx” (protection on all sides) or “Front side” (protection on the front side only).
  • IKxx standard: the IK index followed by 2 digits is the index of protection of electrical equipment from mechanical shocks. It indicates protection against impact energy, expressed in joules. It indicates the equivalent of a mass drop of a certain weight from a certain height. For example, xxx = 01 => material protected from impact energy of 0.15 joules (impact equivalent to a mass drop of 150 g from a height of 10 cm). The IK00 index indicates that the equipment is not protected.
  • ATEX standards: ATEX standards relate to the protection of people working in hazardous areas. There are ATEX compliant industrial monitors for use in hazardous areas. ATEX distinguishes between zones with a high concentration of gas and steam (zones 0, 1 and 2) and zones with a high concentration of dust (zones 20, 21 and 22).
  • MIL-STD-810G / F is an American standard that indicates device reliability. This standard was developed for the US Army, and is currently used for commercial purposes to indicate compliance with environmental conditions.

Which connector do you need to choose for your monitor?

  • VGA Analog Port: this is the most widely used video connector available as standard on an industrial monitor. However, it allows you to get only an analog signal and is not suitable for working with very high resolutions.
  • VGA-DVI port: this is an improved version of VGA that allows you to receive analog and digital signals. Like VGA, it has two screws, which prevents the cable from being pulled out.
  • HDMI and Display Ports: they are increasingly used in consumer goods. They transmit all digital signals (audio and video) over a single cable. They also allow the transfer of very high resolution.
  • LVDS port: this port is preferable to use in the built-in monitor. The monitor is connected to the video card with copper wires and provides high speed data transfer.
  • S-video port: it is used for analog video, which transmits colors and brightness individually.
  • BNC connector: transmits a video signal in analog mode, and also provides audio transmission. It can be used as an analog and digital connection, as an antenna connection or for electronic testing. It can also be used for Ethernet on a thin cable. This is an electrical connector used as the end of a coaxial cable, most often in the radio frequency field.

What type of assembly to choose for your industrial monitor?

Installation of the monitor can be carried out on the wall or bracket, it can also be integrated into the finished system. For fixing, the monitors are equipped with pre-made holes configured in accordance with VESA standard. This norm defines the requirements for screws (M4, M6 or M8), as well as their location.

There are several options for integrating a monitor:

  • Panel mount: monitor, recessed in the rack body, carcass, dashboard, etc. Fasteners are rear and invisible.
  • Rack monitors: for mounting in a 19-inch rack, the monitor is mounted in front to the frame of a 19-inch rack with four screws.
  • Flush mount: identical to the panel mount, but with visible fasteners.

Open frame: a monitor without a case and without a frame, placed in a bare metal frame on which all internal components are fixed. The advantage is that you can customize the outline or casing according to your preference.

Information kiosk (touch terminal)

Information kiosk (touch terminal)

Information kiosk is designed to provide reference information.

Information kiosk

Technically, this is an automated software and hardware complex based on a personal computer, POS terminal, or specialized device. Depending on the tasks, the information kiosk is equipped with a touch screen, barcode scanner, RFID tags, magnetic card scanner.

Information can be displayed on the kiosk screen and / or additionally printed on a printer. As a rule, information kiosks are placed in vandal-resistant, metal cases. Information kiosks can work autonomously or connect to an enterprise computer network. When working offline, information can be updated via the GSM channel or via the Internet.

Information kiosk (touch terminal) 3

Information kiosks can be used by both buyers and sellers. For example, often in stores, customers, choosing and studying a product, do a “re-sorting” – the product returns to the shelves, but not to its place, but where it is convenient. It is difficult for the next buyer to understand the value of the product and find the price tag of this product. It is possible to calculate by the barcode number, but those who have encountered this situation know how long and “annoying” this is. The output is information kiosks with a barcode scanner – just bring the product and scan the barcode, the screen will display the name of the product, its price and brief characteristics.

If the information kiosk is equipped with a touch screen, the buyer can be invited to read the full description of the product and its characteristics. The touch kiosk can provide information throughout the working day, its mode of operation can be around the clock and year-round.

Using a touch kiosk does not require special training or any computer skills from a person. The interaction is intuitive and extremely simple – you must either read the bar code or select menu items with a simple touch of a finger on the touch screen.

Touch kiosks are used both in commercial organizations and in government agencies. For example, information kiosks are installed in the offices of the Pension Fund of Ukraine. With the help of a certificate of compulsory state social insurance, citizens of Ukraine can gain access to data accumulated in the personified accounting system. With the help of a pension certificate, get access to the data of a pension case. Get information about the reception schedules for managers and management specialists, in which the information kiosk is located.

Single window – in state organizations, a touch information kiosk complements the concept of a single window. Without queues, at a convenient time, citizens can receive the necessary information. For example, reception schedules by the heads of departments where a request or document is located, the processing of information and requests can be automated – when documents are submitted, a receipt with a bar code is printed out, at any convenient time the visitor can scan the receipt and get information about which department contains his documents and when they are planned to be issued.

Information kiosks and touch terminals have long ceased to be a novelty. They are installed in stores, salons, offices of various companies and organizations. They are easy to use. Information is always available and to get it, you just need to select the necessary section in the terminal menu. The design and color of the terminal can be any, depending on the requirements and wishes of the customer. You can use serial models or design and manufacture an information kiosk to order.


Information kiosks are a proven and effective business solution that is actively used in the field of digital signage and indoor advertising.

The information kiosk is designed to:

  • tell and show;
  • interest and captivate;
  • guide and encourage action.



The presence of such equipment not only produces the desired effect on visitors, but also helps them to navigate, make a choice in favor of a particular service, and even simply not get lost if it comes to a large building.

Information kiosks are so good in their capabilities and results of use that many entrepreneurs and directors of companies think about their implementation. The Innovative DMC company is just involved in organizing and installing information kiosks in Kiev and throughout Ukraine. For whom is the installation of a kiosk in the territory relevant?

To buy an information kiosk for establishing effective communication with customers, customers, guests and visitors can:

  • trade objects (shops, supermarkets, boutiques);
  • shopping and entertainment centers;
  • sport complexes;
  • cinemas;
  • hotel complexes;
  • administrative premises;
  • government facilities;
  • banking institutions;

The indisputable advantage of the information kiosk is ease of management. So, a user who has encountered this device for the first time will easily figure out where to click and what to do. The kiosk interface is designed in such a way that the control is as simple and intuitive as possible. Just one or two movements – and you get all the information you need about the location, brand or product!

The presence of additional functions implies additional equipment. Thus, information kiosks can be equipped with not only a Full HD touch-screen, but also a device for reading barcodes, RFID tags and cards, a printer, a keyboard and other options.


Information kiosks can work 24/7.

They are ready for operation in various conditions and resistant to various external influences. Provided anti-vandal solutions can protect the owner from damage to property.


The design of information kiosks is carried out in any style and color design, which depends on the wishes of the customer. They can be applied company logos, labels and other images.

Is an investment in an information kiosk profitable? Undisputed, yes!

In terms of efficiency and effectiveness of use, information kiosks are superior to printed materials, static advertising, and even attendants. It is convenient, modern and pleasant for the user! It is profitable and practical for you!

The touch kiosk can be a separate information unit or a part of the system – one of the many devices interconnected. Information updating in this equipment can be carried out directly on site or remotely. In short, the functionality implies complete freedom of action, both for users and for managers responsible for the smooth operation of the information kiosk.

A look into the future of car entertainment systems

Our Internet publication has studied the many infotainment systems currently offered by car manufacturers in order to identify the best of them. Before proceeding to the review of entertainment systems, we would like to note that in our rating we did not include the Tesla S car with its 17-inch screen and excellent control. The reason is simple. This car is affordable to have for a small amount of people, and this brand occupies a limited niche in the car market.

Nevertheless, we were obliged to note the information system of the car, since it works efficiently. Management is carried out by the touch screen. The menu is easy to use. An internet browser is built into the control system.


The ten most useful automotive technologies


True, at first glance at the Tesla screen, it is somewhat discouraging by the amount of various data, menus and submenus. But with careful viewing, everything becomes clear and logical. It’s a pity that the proprietary information system on Tesla’s cars is not available on most vehicles on the market.

Top 10 Car Infotainment Systems. Touch screen in a car 17 

MyLink (in some cars it has a different name – IntelliLink) is often somewhat slow in responding to touch on the touch screen. But this system offers ample opportunity to configure and connect additional equipment. For example, if your car does not have a navigation system, then installing the special BringGo application on your smartphone, you can, by connecting the phone to the car’s infotainment system, display the navigation map from the phone.



True, it is worth noting that this feature is available only on economy class cars (for example, Spark, Sonic and Trax).


In addition to the touch control, the MyLink system is expanded with several real buttons for quick and easy access to the most important functions of the car.


  • Infiniti InTouch


Top 10 Car Infotainment Systems. Touch screen in a car 19

The new Infiniti infotainment system debuted on the Q50. At first glance, two screens can be misleading. One screen is controlled by touching the LCD screen, the other display is controlled using regular buttons. Unfortunately, the touch screen is not so fast in response to touch. Both screens have high resolution, which makes the information displayed on them readable.


The only minus is the brightness of the screens (quickly get dirty from the fingers). Therefore, the driver always needs to have a rag to wipe the screens.


Infinity allows you to connect the Internet to the system in order to use social media on the car screen. It is also possible to use Google search. In addition, the car manufacturer has provided the opportunity to use your smartphone to diagnose the car and display on the phone screen fuel consumption, power reserve, speedometer and other data.

Screen size allows the system to look high-tech. As a rule, it is installed on Kia premium cars, adding value and luxury to the vehicle. It is worth noting that the Kia navigation system uses Google Maps.


But the main drawback is the slow operation of the control, which can be annoying and very distracting while driving.


  • Cadillac CUE


Top 10 Car Infotainment Systems. Touch screen in a car 25

The Cadillac CUE system is quite advanced, and its technology feature is not found on other cars. Some proximity sensors and tactile feedback. Sensors are needed to hide the necessary icons until your hand approaches the screen. This is done so as not to occupy the screen. As soon as your finger approaches the screen, menu icons appear on the displays. The tactile feedback function is necessary in order to understand, without looking at the screen, that you pressed the button. This is the same as on some mobile phones when dialing a slight push in the fingers.


With a resolution of 800 × 480, the graphics look acceptable, but still the touch controls are somewhat lacking in responsiveness.


It is clear that CUE is still in its infancy, and all the news and innovations are yet to come. We look forward to new car models along with a new infotainment system in which the software will be optimized and run faster.



  • MyFord Touch


Top 10 Car Infotainment Systems. Touch screen in a car 27

MyFord Touch is slow, bad and prone to breakdowns, and also distracts the driver from the road. But there are pluses. In this system, one of the best voice management software. It’s also very simple. The display is divided into four different screens with which you can use the phone, climate control, navigation and media applications. In fact, each section of the settings refers to every corner of the screen. This is done so that you can, without being distracted, quickly find the necessary function.


But the main advantage is voice control, which allows you to use many functions of the car without being distracted from the road.



An embedded computer with a touch screen is used as a multimedia center, to manage automation devices, to control the environmental and physical safety of the home.


The central element of the “smart house” can be a touch-screen computer built into the wall. Such a computer does not need a “mouse”, the buttons can be pressed directly with the finger on the screen, and the special keyboard for typing is replaced by special on-screen keyboards. Owners of the increasingly popular handheld computers know how convenient touch screens are.

An embedded computer with a touch screen can be useful, for example, as a multimedia center with which you can play music, movies or even display digital photos. The music library, film library and photo archive can be placed on another computer in the home network. A similar computer can be used to control automation devices (including for reprogramming them), to control the environmental and physical safety of the home. But this will require special software.

You can use a separate touch monitor. It can be mounted by installing a touch screen on a conventional LCD monitor. The installation operation is quite complicated, so specialized companies are engaged in the assembly of touch screens.

Touch screens themselves differ in manufacturing technology. According to the principle of operation, they are resistive, on surface-acoustic waves, infrared and projective-capacitive (for more information about sensor technologies, see

For smart houses, surface acoustic acoustic and resistive screens (such as IntelliTouch and AccuTouch by EloTouchSystems) are the best. SAW screens provide high image quality, accurately recognize the touch of a finger or pen, are not afraid of scratches, and are sensitive to touch force. Resistive screens have been designed for use in aggressive environments, therefore they are superior to other screens in reliability and durability. Resistive touch screens are most resistant to contamination, their surface is not afraid of liquids, condensate, vapors, but such screens have less transparency.

Embedded computers with touch screens are relatively inexpensive. A foreign-made computer with a 19-inch LCD screen costs $ 1,300-1,500 (domestic models are $ 200 cheaper), with a 12-inch one – about $ 1,000.

Offering embedded computers, you need to take care of creating a control program, not forgetting the convenience of the interface (for example, large buttons).


Smart House Automation

Smart House is an automated management of all that you can drive around in your house. The house has a lot of routine work: turn on / off, start / stop, open / close, louder / quieter, warmer / colder, etc. To complete all these actions in a two-story house, leaving for the weekend, coming home from work, receiving guests, you will have to spend a decent amount of time. All this can be done in a minute from one remote control.

Smart house ensures the coordinated operation of all electrical equipment. Externally, a cottage with an installed smart home system is not much different from an ordinary house. Nothing in the interior and exterior of the house betrays that it has a modern control system. Outside, only beautiful switches are visible, as well as bright and colorful touch screens located on the walls in convenient places, for example, in the living room or in the kitchen. One touch of the screen and the light turns on smoothly, the curtains close, music starts playing, etc.

Everything is now under control. No need to go up to the second floor to turn off the lights or turn off the TV. And if you left and forgot to suddenly turn off the iron, then you can turn it off without returning. Using a mobile phone, you can send the command “turn off everything” or one specific outlet, or vice versa turn on the light in the hallway or in the bedroom and thereby simulate the presence of the owners. You can, being in your office, go over the Internet to the server of your smart home and view the lights on, cameras in the hallway or bedroom, as well as how many people have visited the house in your absence.

Smart Home devices and Z-Wave technology will give you an absolute sense of comfort!

Do you want to be proud of your house? Do you want to control the light, climate, any device, take care of the garden without getting up from your chair?

The world is becoming digital, Touch screen monitor and touch panels

The world is becoming digital, and more and more of our daily activities are being digitized.


One technology that makes this transition easier is touch screen technology. Most of us are familiar with her. In the end, if you have a smartphone, then you interact with the touch screen daily.

The usefulness and practicality of touch screen technology is undeniable. And in fact, so much so that enterprises have realized the benefits of introducing this technology. However, despite its simplicity for end-users, this technology has something more than it seems at first glance.

First, we’ll look at why investing in touch monitor technology and discuss the potential of touchscreen monitors for your company. To understand this potential, we need to dive into various types of sensory technologies.

Types of the Touch screen monitor

When it comes to touch screen technology, we know that there are a number of different types of technologies on the market, each of which has its own set of characteristics.

Resistive, optical, projected-capacitive, and infrared are the four most common touch screen technologies. Each of them has different applications and can provide significant support to your business. For example, if you want to create and deploy touch-screen solutions for public places, such as an open-air shopping center, it would be helpful to understand the strengths and weaknesses of various touch-screen technologies to choose the one that suits your application. There are panels that are ideal for creating monitors that your customers can easily interact with in bright sunlight. Other types of panels are preferred for touch screen applications that must withstand harsh weather conditions. The following is a description of the characteristics that are typically associated with each of these technologies.

Resistive Touch Technology

Resistive touch technology can be found in a variety of applications, including touch monitor and car navigation systems. Resistive panels are pressure sensitive, which means that they use pressure exerted directly on the screen as a means of detecting commands.

Resistive touchscreens are typically one-touch displays and typically have a size of less than 20 inches.

Unlike other sensor technologies, resistive touch panels are coated with two layers of transparent electrode film, separated by gaskets. This pressure-based input method means that resistive panels can work with almost any type of touch, including finger touch, stylus, and even with a glove.

Due to these layers of the film, light transmission is not as strong as when using other types of sensor technologies. Resistive touch panels are also known as the most short-lived touch panel technology because pressure needs to be applied to the screen.

Advantages of resistive sensor technology:

  • Cost-effective touch solution
  • Ability to work with your finger, stylus and glove
  • Can be used if there are drops of water on the screen.

Disadvantages of resistive sensor technology:

  • Low light transmission
  • Less longevity than other sensor technologies
  • Unable to support true multitouch.

Optical Image Touch Technology

Touch optical image technology uses infrared cameras and light to detect touch input. The accuracy of touch detection on optical touch displays may vary depending on the components used.

The touch panels of the optical image are multi-touch and usually have a size of 19 to 100 inches. Since touch recognition on these devices works through visualization, you can use any form of touch to enter commands, whether it be a finger, a stylus, a gloved touch, etc.

The light transmission on the touch screen monitor with optical visualization is very good, because there are no interfering coatings on the screen itself. In addition, optical touch displays tend to work for a long time because the light touches associated with this technical option usually do not cause wear.

Optical touch is a technology often used for large screen touch applications.

Advantages of optical image sensor technology:

  • High light transmittance for crisp, clear images
  • Durability
  • You can use any input method (finger, stylus, glove, etc.)
  • Multi touch screen monitor

Disadvantages of optical image sensor technology:

  • Displays are not as compact as with other touch technologies.

Projected-capacitive Technology

Projected-capacitive technology is a sensor technology commonly used to make smartphones.

Projected-capacitive technology is commonly used on smaller touch screens and has high-precision touch recognition and fast response times. Projection-capacitive touch panels are capable of multi-point touch and usually have a size of less than 32 inches.

Since projected-capacitive touch screens detect touch commands using electric currents, it is more difficult to create projected-capacitive touch panels of a larger size than a smaller one. Unlike resistive touch technology, projected-capacitive touch panels can function with finger input or a conductive pen, but not with a gloved touch.

Advantages of projected-capacitive technology:

  • Best user experience
  • High accuracy touch detection
  • High light transmittance
  • Durability
  • Multi touch screen monitor

Disadvantages of projected-capacitive technology:

  • Not compatible with glove work
  • Higher cost

The light transmittance of the projection capacitive touch panels is very good, as is the accuracy of touch detection. In addition, glass and plastic coatings on projection-capacitive touch displays are generally very durable and dustproof.

Projected-capacitive technology is often touted as the best for users of all sensory technologies.

Infrared sensor touch screen monitor

Infrared sensor technology uses light beam interruption to detect sensor commands. In touch infrared displays, infrared rays are arranged in a grid over the panel itself, and touch points are calculated when the rays are interrupted.

Infrared touch screens are capable of multi-point touch and can have sizes from 20 to 150 inches. Commands can be entered on the infrared touch panel using a finger touch, a thick stylus, or a gloved touch, although the accuracy of determining the touch may vary depending on the internal components used.

Infrared touch panels typically have good light transmittance and are quite durable, however sunlight can cause glare and reflections that adversely affect the user’s perception.

Like the optical image sensor technology, infrared sensor technology can be used for large screen applications.

Advantages of infrared sensor technology:

  • High light transmittance
  • Durability
  • Multi touch

Disadvantages of infrared sensor technology:

  • Sunlight may adversely affect user experience.
Resistive SAW Optical Image Projected-capacitive Infrared
Typical Display Size <20” <20” 19-100” <32” 20-150”
Multi touch not typical, but some have demonstrated not typical, but some have demonstrated yes yes yes
Entry method finger or stylus finger or soft tip pen finger or something finger or conductive pen finger or thick stylus
Problems need a strong touch, but not sharp objects rain, dust pollution dust pollution, strong light source> 500 lux or> 840 nm cannot be used with thick gloves sunlight, wide rim contamination
Usage to touch the base with one-touch to touch the base with one-touch Medium and large, indoors For a better user experience Large size, electronic boards


Who uses touch screen technology?

As we have already noted, there has been a significant shift towards touch panel technology, and more and more enterprises are introducing touch panels every year. As a fact, today it will be difficult for you to find a business that does not implement any of the technologies of touch panels.

The reason for this is that companies are aware of how profitable the use of touch panels is, due to their ease of use of the interface and the ability to increase productivity and improve customer service. Industries using touch panel technology include:

  • Smart retail and POS
  • Education
  • Industrial use and smart factory
  • Finance and financial services
  • Medical applications

How do these industries implement touch screen technology? Let’s discuss some examples of how touch panels are used today.

Food and drink

Long lines in restaurants during working hours are always problematic for customers and store employees. Waiting too long for a service can lead to impatience, loss of customers, and negative reviews. Touch screen monitor solutions can act as a self-service point for customers to place an order and pay for it while they wait. In addition, they can display advertised content, such as promotions and events, to attract customers.

Remember the days when arrival at the airport began with waiting in line for a boarding pass? Well, fortunately for all of you inveterate travelers, touch panel technology has changed this process for the better. Currently, all you have to do is enter your information, scan your passport, and you’re done. Combine this with self-service kiosks at public transportation stops in cities such as London and New York, and travelers can increase the efficiency of their trip or travel to work.

Banks and Finance

Banking institutions use digital signatures to digitize their workflow, saving time and money. Digitally signed solutions offer all the functionality of traditional pen-and-paper signing methods, but have many additional benefits, such as increased security and much more. Using a digital signature, documents can be easily stored – there is no need for filing cabinets; the ability to send documents to customers in digital form and are easy to retrieve for future use.

Benefits of Touch Screen Technology

Customized processes

Touch panel technology allows you to control your display with your fingers, resulting in faster display operations. In a business setting, this reduction in time can provide many benefits, including reduced waiting times in the queue and faster service to your customers. Moreover, these advantages can create the effect of positive results in the form of dominoes, including increasing customer satisfaction, improving the quality of customer service and increasing brand loyalty on the part of your customers.

Ease of use

Since the advent of touch smartphones, the use of touch technologies has become almost universal. Thus, everyone became a master. There is an advantage of this technology in the ease of its implementation. A simple implementation will allow employees to start using the technology immediately, without the need for training, which will speed up the work.

Engagement and Interactivity

Since touch panels are so versatile in their implementation methods, they have the ability to positively influence user experience. For example, displaying engaging content to engage with consumers is a good way to elevate your business over your competitors.

Self-service function

In addition to interacting with employees, touch panels can be useful for customers. In this, the touch panel technology allows users to service themselves. This functionality can be useful for information services of a shopping center or hotel, as well as for choosing dishes in a restaurant, if you name only a few applications. This allows employees more time to focus on higher priority tasks and allows customers to take responsibility for their own experience.


At its core, touch screens must be able to withstand constant physical interaction. Keeping in mind longevity and limited replacement, manufacturers of touch panels strive for the longest possible life and prevent accidental damage.

Clutter reduction

Non-touch panels often require additional peripherals to operate. The introduction of touch technology eliminates the need for these accessories and, thanks to faster operation, provides a more rational use of the workspace.

Increased efficiency

Touch panel technology can improve workplace efficiency, for example, by reducing the waiting time in the queue. This increase in efficiency leads to ultimate benefits, allowing employees to serve more customers, thereby improving the quality of customer service.

Cost effective

Digitizing your workflow with touchpad technology can reduce costs by eliminating the cost of office supplies. Touch displays can also reduce storage costs by eliminating the need for physical storage of documents.

What features should a touch screen have?

Generally, any type of touch screen technology you choose should have the following characteristics:

Touch panels should be easy to use.

Since you will ask employees to use a new type of technology, it should be easy for them to start using it right away. This will help save time on training employees in terms of how to use new technologies, and save money by allowing them to freely start using this technology to improve your business.

Touch panels should be easy to implement.

Implementing your new touchpad technology should be the least of your worries. Touch panel technology with a wide range of compatibility with various operating systems makes the implementation process smooth and hassle-free, allowing you to use systems that your employees are already familiar with.

What is a multi-touch screen

What is a multi-touch screen and how to distinguish it from a simple touch screen?

The modern world of technology is regularly updated with new gadgets and various technical equipment. Almost everyone heard such a buzzword as “multi-touch screen”. However, not all users can rationally evaluate the features and benefits of this device. Let’s understand in more detail what a multi-touch screen looks like, what kind of technological innovation is this?

  • 5 How to understand if there is a multi-touch in the device?


Multi-touch: term and history

Multi-touch is a touch screen. It is able to respond to several touches at the same time. The keyboard in this device is missing, and the main tool is a light touch with your fingers. If you translate the term from English, it means “multiple touch.”

Back in the sixties of the last century, great minds worked on creating a high-tech touch screen. All these innovations were applied in ENRC (European Nuclear Research Center). The society first saw such screens in New York, and their developer was Jeff Khan. It was at the beginning of the XXI century that everyone in the world started talking about unrealistic technologies, when you can control a monitor picture with just one touch of a finger. It was a real technological explosion, and a huge step in the world of electronics.

The Importance of Multi-Touch in the Modern World

Now that we have become acquainted with this device, the question arises of what does a multi-touch screen mean in the modern world? Maybe there is no point in this function and not everyone is ready to overpay for it? It only seems so, in fact, such touching the screen not only simplifies the task, but also saves the user time. Of course, you don’t notice how mechanically you try to enlarge the picture with two fingers. You must admit that this function is very convenient and there is perplexity when the new touch gadget does not respond to this action.

If an ordinary user can live without these innovations in the device, then an avid gamer will encounter a lot of difficulties. Today, many well-known manufacturers adapt the gameplay control specifically for the multi-touch screen. They simply refuse button commands and use modern technologies to simplify the game process.


Using multi-touch in gadgets:

  • Management of games and entertainment applications.
  • One-touch image scaling.
  • Easy application management and time saving.

Distinctive features of multi-touch and conventional touch screen

Do not confuse these two screens. A conventional sensor responds to only one touch; for it, the sequence of the process is of particular importance. The multi-touch screen control is based on several touches simultaneously.

Regularly, engineers from leading companies develop new combinations that should facilitate the operation and management of electronic devices. Owners of smartphones have long felt the benefits of the zoom feature. Many manufacturers claim that their gadgets are able to recognize 10 to 20 touches simultaneously.

Multi-touch display: device and application

Screen Design

Almost all modern mobile devices support this feature. And what is multitouch in a tablet? Here the answer will be simple – it is freedom of action and time saving when working with many applications. Many laptops and e-books also have this feature.

Such a screen can be developed in several technological ways, but the most practical and popular remains – resistive. Samuel Hurst is its main developer. The main advantage in this production scheme is low cost. True, this method was popular until 2008. After that, more universal options for creating a multi-touch screen were developed: tensometric, optical and inductive touchscreens. Today, many creators are working on a projected-capacitive touch screen, it is the famous company Apple that uses it in their gadgets.

What does this high-tech screen consist of? A glass panel covered with a resistive layer is called a capacitive monitor. Four electrodes are placed in the corners of the display, which pass alternating voltage. As soon as the finger touches the monitor, current leakage instantly occurs. The larger the display, the more touch points the device recognizes.

Additional features

Customers around the world are buying gadgets that feature a modern feature. Not surprisingly, Apple is actively introducing such screens into all of its mobile devices. Surely everyone who held such a device in their hands can understand its advantages over others. But still, let’s pay attention to additional features for those who doubt the functionality of such equipment:

  • Simple operation, saving time.
  • It is convenient to use such devices, since they harmoniously fit into the everyday life of a person.
  • The device can be operated by several users, but before that you need to make sure that the appropriate applications are present.
  • Management is carried out on an intuitive level, so not only children, but also pensioners, can handle the devices. Buttons are always misleading, and their absence simplifies the understanding of the workflow.

Application area

Capacitive multi-touch screen is understandable to almost everyone, which is why it is implemented not only in computer devices and mobile devices, but also in household appliances. Even children can easily figure out how to operate such a gadget. The equipment has an additional plus if control is via a multi-touch sensor. Especially popular are various multitouch panels in public places: educational institutions, medical centers, shopping pavilions and children’s entertainment centers. Often they are used to provide the necessary information and as advertising panels.

Visitors easily navigate by electronic map and get acquainted with product catalogs. Such systems are equipped with a microphone and speakers, which also simplifies the process of perceiving the necessary information for potential buyers and visitors. It is very important that the picture of the display is always distinguished by brightness and contrast, while the monitor is protected from scratches and other possible mechanical damage. Every entrepreneur wants to purchase such a multi-touch panel, as this increases the level of perception and adds prestige to any company.

What is a multi-touch screen 39

How to understand if there is a multi-touch in the device?

It is very important to be able to recognize the presence of such a screen even before purchase. Today, there are many scammers who give out ordinary touch devices as a high-tech multi-touch screen:

  • Even in the trading pavilion, turn on your device and go to the Google Maps menu. If the device has multi-touch, then scaling in this program will occur with two touch of the fingers. Otherwise, this means that the seller is giving you incorrect information, so purchase a different model.
  • Before making a purchase, go to the manufacturer websites. There you will find detailed information about each device.
  • The resistive screen in tablets and smartphones is not equipped with a multi-touch function, however, there are such users who violently prove the opposite. It’s just that on such screens you can implement only the function of rotation and scaling with two fingers, but this is where its possibilities end. You won’t be able to play modern games, which will certainly upset every user who was counting on a pleasant gameplay.

Today, monitors are not large enough to work on them with both hands, but in the near future every gadget will have such technological multi-touch screens. Everything that was once shown in science fiction films is being carried out and is actively being introduced into the everyday life of people. Great minds regularly include new features in gadgets and use the multi-touch screen to control, while developing new combinations and improving the technology itself. The touch screen is the face of current technology, and behind it, of course, is our whole future.

Advantages of touch screens

Touch screens are widely used in payment terminals at ATMs, etc. Unlike keyboards, they do not have moving parts, so they are durable: safe, vandal-proof and weatherproof. The great thing about touchscreen technology is that it is incredibly easy to use. Touch screens can display as much information (and as many touch buttons) as people need to perform a specific task, but no more, which allows people to perform a rather complex process in a very simple and systematic way. This is why touch screen technology has proven ideal for use in public information kiosks, ticket machines at railway stations, electronic voting machines, self-service grocery cash registers, military computers, and in many similar applications where using computers with screens and keyboards would be too problematic. Most of us now have Apple or Android smartphones that have multi-touch screens. The big advantage here is that the display can show you a screen designed specifically for what you are trying to do with it. If you want to make a phone call, it can display the usual numbers 0–9 so you can dial the number. If you want to send an SMS text message, it can display the keyboard (in alphabetical order or in QWERTY order). If you want to play games, the display may change again. Such touch displays are incredibly versatile: every minute they change according to your expectations. Photo: PC touch screens are still relatively rare, but they are very useful when hovering and dragging makes more sense than typing and clicking. This image shows a system called DSIMS (Deployable Ship Integration Multitouch System), used to teach people how to control the movements of aircraft and other equipment on board aircraft carriers. You just click on the plane and drag it to where you want to move, on the flight deck. The first invention, which bears any resemblance to the use of a modern touch screen, was called a light pen (shown in the photo above), a stylus with a photocell at one end and a wire going to a computer at the other end, which can draw graphics on the screen. It was developed in the early 1950s and became part of one of the first computer systems with the Project Whirlwind graphics system. However, the light pens did not work like modern touch screens, because there was nothing special in the screen itself: all the smart things happened inside the pen and the computer to which it was connected. In the 1960s and early 1970s, another key area in the development of touchscreens was the work of computer scientists specializing in what is called human-computer interaction (HCI), which sought to bridge the gap between people and computers. Among them were Douglas Engelbart, the inventor of the computer mouse; Ivan Sutherland, pioneer of computer graphics and virtual reality; and Alan Kay, a colleague from Sutherland who helped create a graphical user interface (or GUI – an image-based desktop used on almost all modern computers). The first gadget that worked like a modern touchscreen was called the “Discrimination Contact Sensor,” and it was patented on October 7, 1975 by George S. Hurst and William S. Colwell of Elographics, Inc. Much like a modern resistive touch screen, it was a device with two electrically conductive contact layers separated by an insulating layer that could be pressed together with a pen. The important thing is that it was designed to work “with a writing instrument (a pen is shown on the patent drawings), and not with any part of the writer’s hand.” So it was not like a modern touch screen device. Many people think that touch screens only appeared when Steve Jobs introduced the Apple iPhone in 2007, but by that time touch-sensitive laptop computers had been around for 20 years. One of the first was the Linus Write-Top, a large tablet computer released in 1987. Five years later, Apple released the ancestor of its iPhone in the form of Newton, a laptop computer manufactured by Sharp, Japan. Guided by a pen-like stylus, it featured an innovative, but somewhat erratic handwriting recognition, but never had commercial success. Touch input and handwriting recognition were also featured in the Palm PDA series (personal digital assistants), which were extremely popular in the mid-1990s. All modern touch screen gadgets, from iPhones and iPads to tablets, owe these inventive innovators and their drawing machines!

Touch screen technology

Touch screen technology

Touch screen – an information input device, which is a screen that responds to touch.


The touchscreen was invented in the United States as part of programmed learning
research. The PLATO IV computer system, which appeared in 1972, had a touch
screen on a grid of infrared rays, consisting of 16 × 16 blocks. But even such low
accuracy allowed the user to choose the answer by clicking on the right place on the
In 1971, Samuel Hurst (the future founder of Elographics, now Elo TouchSystems)
developed an elograph – a graphic tablet that operated on a four-wire resistive principle
(U.S. Patent 3,662,105). In 1974, he managed to make the elograph transparent; in
1977, he developed a five-wire screen. Together with Siemens, Elographics managed
to make a convex touch panel that was suitable for picture tubes of that time. At the
1982 World&#39;s Fair, Elographics introduced a touch-screen TV.
In 1983, the HP-150 computer with an IR-touch screen was released. However, in those
days, touch screens were used mainly in industrial and medical equipment.
Consumer devices (telephones, pocket PCs, etc.) included touch screens as a
replacement for a tiny keyboard when devices with large (full front panel) LCD screens
appeared. The first handheld gaming console with a touchscreen is the Nintendo DS,
the first mass-media device that supports multi-touch is the iPhone.


Touch screens are used in payment terminals, information kiosks, equipment for trade
automation, handheld computers, mobile phones, game consoles, and operator panels
in the industry.

Advantages and disadvantages of handheld devices

 The simplicity of the interface.
 The device can combine small sizes and a large screen.
 Speed dial in a relaxed atmosphere.
 The multimedia capabilities of the device are seriously expanding.
 No tactile feedback
 High power consumption.
 Particularly thin screen models, even with minor damage, run the risk of being
cracked or even broken.
 Hygiene of Screen.
Advantages and disadvantages of stationary devices

In information and vending machines, operator panels and other devices that do not
have active input, touch screens have established themselves as a very convenient way
of human interaction with the machine.

Touch screen technology 41


 Increased Reliability.
 Resistance to harsh external influences (including vandalism), dust and moisture
 (For capacitive screens). No tactile feedback.
 When working with a vertical screen, the user is forced to keep his hand on
weight. Therefore, vertical screens are suitable only for occasional use like
 On a horizontal screen, hands obscure the view.

Even with a sharp pen, parallax limits the accuracy of positioning operator actions on
touch screens without a cursor. At the same time, using the cursor creates additional
difficulties for the operator, reducing ergonomics.
When using the screen with not completely clean hands, use is difficult due to the
the difficulty of moving the fingers, as well as the resulting fingerprints and spots, if the
screen does not have special coatings to neutralize them.
These disadvantages do not allow using only the touch screen in devices with which a
person works for hours. However, in a well-designed device, the touch screen may not
be the only input device – for example, at the cashier’s workplace, the touch screen can
be used to quickly select goods, and the keyboard to enter numbers.

Principles of operation of touch screens

There are many different types of touch screens that work on different physical

Resistive Touch Screens – Four-wire screen

The principle of operation of a 4-wire resistive touch screen

The principle of operation of the 5-wire resistive touch screen
The resistive touch screen consists of a glass panel and a flexible plastic membrane.
Both the panel and the membrane are coated with a resistive coating. The space
between the glass and the membrane is filled with micro-insulators, which are evenly
distributed over the active area of ​​the screen and reliably insulate conductive surfaces.
When the screen is pressed, the panel and membrane are closed, and the controller,
using an analog-to-digital converter, detects the change in resistance and converts it
into touch coordinates (X and Y). In general terms, the reading algorithm is as follows:
A voltage of + 5V is applied to the upper electrode; the lower one is grounded. The left
and right are short-circuited and the voltage on them is checked. This voltage
corresponds to the X-coordinate of the screen.
Similarly, + 5V and ground are applied to the left and right electrodes, and the Y-
coordinate is read from the top and bottom.
There are also eight-wire touch screens. They improve tracking accuracy, but do not
increase reliability.

Five-wire screen

The five-wire screen is more reliable due to the fact that the resistive coating on the
membrane is replaced by a conductive one (the 5-wire screen continues to work even
with a slotted membrane). A resistive coating with four electrodes at the corners is
applied to the rear window.

Initially, all four electrodes are grounded, and the membrane is “pulled” by a resistor to
+ 5V. The voltage level on the membrane is constantly monitored by an analog-to-digital
converter. When nothing touches the touch screen, the voltage is 5 V.

As soon as the screen is pressed, the microprocessor picks up the change in
membrane voltage and starts calculating the contact coordinates as follows:
A voltage of + 5V is applied to the two right electrodes, the left ones are grounded. The
voltage on the screen corresponds to the X-coordinate.
The Y-coordinate is read by connecting to the + 5V of both upper electrodes and to the
“ground” of both lower.

Resistive touch screens are cheap and pollution resistant. Resistive screens respond to
touch with any smooth, hard object: hand (bare or gloved), pen, credit card, pick. They
are used wherever vandalism and low temperatures are possible: for the automation of
industrial processes, in medicine, in the service sector (POS-terminals), in personal
electronics (PDAs). The best samples provide accuracy of 4096 × 4096 pixels.
The disadvantages of resistive screens are low light transmission (not more than 85%
for 5-wire models and even lower for 4-wire), low durability (no more than 35 million
clicks at one point) and insufficient vandal resistance (the cover-up is easy to cut).
Matrix Touch Screens
Design and principle of operation

The design is similar to resistive, but simplified to the limit. Horizontal conductors are
applied to the glass, vertical to the membrane.

When you touch the screen, the conductors touch. The controller determines which
conductors are closed and transfers the corresponding coordinates to the


They have very low accuracy. Interface elements have to be specially arranged taking
into account the cells of the matrix screen [8]. The only advantage is simplicity,
cheapness and unpretentiousness. Typically, matrix screens are polled line by line
(similar to a matrix of buttons); This allows you to set up multi-touch. Gradually replaced
by resistive.
Capacitive Touch Screens
Design and principle of operation

Capacitive touch screen operating principle

A capacitive (or surface-capacitive) screen uses the fact that an object of large capacity
conducts alternating current.

The capacitive touch screen is a glass panel coated with a transparent resistive material
(usually an alloy of indium oxide and tin oxide is used). The electrodes located at the
corners of the screen supply a small alternating voltage (the same for all angles) to the
conductive layer. When you touch the screen with your finger or other conductive
object, a current leakage appears. Moreover, the closer the finger to the electrode, the
lower the screen resistance, which means that the current strength is greater. Current in
all four corners is recorded by sensors and transmitted to the controller, which
calculates the coordinates of the touch point.
In earlier models of capacitive screens, direct current was used – this simplified the
design, but when the user contacted the ground poorly, it led to malfunctions.
Capacitive touch screens are reliable, about 200 million clicks (about 6 and a half years
of clicks with an interval of one second), do not let in liquids and tolerate non-conductive
pollution perfectly. Transparency at 90%. However, a conductive coating located directly
on the outer surface is still vulnerable. Therefore, capacitive screens are widely used in
machines that are only installed in a weatherproof room. Do not respond to gloved

It is worth noting that due to differences in terminology, surface and projection-
capacitive screens are often confused. According to the classification used in this
article, the screen, for example, the iPhone is projective-capacitive, and not capacitive.
Projection Capacitive Touch Screens
Design and principle of operation

Projection Capacitive Touch Screen

On the inside of the screen is a grid of electrodes. The electrode together with the
human body forms a capacitor; Electronics measures the capacitance of this capacitor
(gives a current pulse and measures the voltage).

Samsung was able to install sensitive electrodes directly between the sub-pixels of the
AMOLED screen, which simplifies the design and increases transparency.

The transparency of such screens is up to 90%, the temperature range is extremely
wide. Very durable (bottleneck – sophisticated electronics that handle clicks). PESE can
use glass up to 18 mm thick [10], which leads to extreme vandal resistance. They do
not respond to non-conductive contaminants, conductive are easily suppressed by
software methods. Therefore, projection-capacitive touch screens are widely used in
personal electronics and in machines, including those installed on the street. Many
varieties support multi-touch.

Touchscreens for surface acoustic waves
Design and principle of operation

The screen is a glass panel with piezoelectric transducers (PES) located at the corners.
At the edges of the panel are reflective and receiving sensors. The principle of operation
of such a screen is as follows. A special controller generates a high-frequency electrical
signal and sends it to the probe. A probe converts this signal into a SAW, and reflective
sensors reflect it accordingly. These reflected waves are received by appropriate
sensors and sent to the probe. The probes, in turn, receive reflected waves and convert

them into an electrical signal, which is then analyzed using a controller. When you touch
the screen with your finger, part of the energy of the acoustic waves is absorbed. The
receivers record this change, and the microcontroller calculates the position of the touch
point. It reacts to touch with an object that can absorb a wave (finger, gloved hand,
porous rubber).
The main advantage of a screen on surface acoustic waves (SAW) is the ability to track
not only the coordinates of the point, but also the pressure (here, rather, the ability to
accurately determine the radius or area of ​​pressure), due to the fact that the degree of
absorption of acoustic waves depends on the pressure at the point touch (the screen
does not bend at the touch of a finger and does not deform, therefore, the force of
pressing does not entail qualitative changes in the processing by the controller of data
on the coordinates of the impact, which captures only the area b, overlapping the path
of acoustic pulses). This device has a very high transparency, since the light from the
imaging device passes through glass that does not contain resistive or conductive
coatings. In some cases, glass is not used at all to combat glare, and emitters, receivers
and reflectors are attached directly to the screen of the display device. Despite the
complexity of the design, these screens are quite durable. According to the statement
of, for example, the American company Tyco Electronics and the Taiwanese company
GeneralTouch, they withstand up to 50 million touches at one point, which exceeds the
resource of a 5-wire resistive screen. Surfactant screens are used mainly in slot
machines, in guarded help systems and educational institutions. As a rule, surfactant
screens are distinguished into ordinary ones – 3 mm thick, and vandal resistant – 6 mm.
The latter withstand the fist of an average man or the fall of a metal ball weighing 0.5 kg
from a height of 1.3 meters (according to Elo Touch Systems). The market offers
options for connecting to a computer both through the RS232 interface, and through the
USB interface. At the moment, controllers for SAW touch screens are more popular,
supporting both types of connection – combo (data from Elo Touch Systems).
The main disadvantage of a SAW screen is a malfunction in the presence of vibration or
when exposed to acoustic noise, as well as when the screen is dirty. Any foreign object
placed on the screen (for example, chewing gum) completely blocks its work. In
addition, this technology requires touching with an object that necessarily absorbs
acoustic waves, that is, for example, a plastic bank card is not applicable in this case.
The accuracy of these screens is higher than matrix ones, but lower than traditional
capacitive ones. As a rule, they are not used for drawing and entering text.
Infrared touch screens

The principle of operation of the infrared touch panel is simple – the grid formed by
horizontal and vertical infrared rays is interrupted when you touch the monitor with any
object. The controller determines where the beam was interrupted.
Infrared touch screens are afraid of pollution and therefore are used where image
quality is important, for example, in e-books. Due to its simplicity and maintainability, the
circuit is popular with the military. Often on this principle do the keyboards of intercoms.
This type of screen is used in Neonode mobile phones.
Optical touch screens

The glass panel is equipped with infrared illumination. At the glass-air boundary, total
internal reflection is obtained, at the glass-foreign object boundary, light is scattered. It
remains to capture the scattering picture, for this there are two technologies:
In projection screens, a camera is placed next to the projector. This is how, for example,
Microsoft PixelSense works.
Or they make photosensitive an additional fourth sub-pixel of the LCD screen.

Strain gage touch screens

React to screen deformation.


The accuracy of strain gauge screens is low, but they
withstand vandalism perfectly. The main application is ATMs, ticket machines and other
devices located on the street.
DST touch screens
Main article: Dispersive Signal Technology
The touch screen DST (Dispersive Signal Technology) responds to glass deformation.
You can tap the screen with your hand or any object. A distinctive feature is the high
reaction rate and the ability to work in conditions of severe screen contamination.

Induction Touch Screens

The induction touch screen is a graphic tablet with an integrated screen. Such screens
respond only to a special pen.

They are used when a reaction is required precisely by pressing with a pen (and not
with a hand): high-end art tablets, some tablet PC models.

Types of Touch Screen Monitor

Types of Touch Screens

The fashion for touch screens literally swept the whole world of high technology. Now a rare cell phone or player does without a “touchscreen”, and the general scope of touch-sensitive displays is completely unlimited. It is these facts that made us tell you about the types of touch screens and their applications.

The touch screen is a device for input and output of information through a touch-sensitive display and gestures. As you know, the screens of modern devices not only display an image, but also allow you to interact with the device. Initially, familiar buttons were used for such interaction, then the no less well-known mouse manipulator appeared, which greatly simplified the manipulation of information on the computer display. However, the “mouse” for work requires a horizontal surface and is not very suitable for mobile devices. This is where an addition to the regular screen comes to the rescue – Touch Screen, which is also known as Touch Panel. That is, in fact, the touch element is not a screen – it is an additional device installed on top of the display from the outside, protecting it and serving to enter the coordinates of touching the screen with a finger or other object.


Today, touch screens are widely used in mobile electronic devices. Initially, the touchscreen was used in the design of handheld personal computers (PDAs, PDAs), now communicators, mobile phones, players and even photo and video cameras hold the lead. However, the technology of controlling a finger through virtual buttons on the screen turned out to be so convenient that almost all payment terminals, many modern ATMs, electronic information kiosks and other devices used in public places are equipped with it.

Touch screen laptop

It should be noted laptops, some models of which are equipped with a rotatable touch screen, which gives the mobile computer not only broader functionality, but also greater flexibility in managing it on the street and on weight.

Unfortunately, there are not many similar laptop models, popularly referred to as “transformers”, but they are.

In general, the touch screen technology can be described as the most convenient when you need instant access to control the device without preliminary preparation and with amazing interactivity: the controls can change each other depending on the function being activated. Anyone who has ever worked with a touch device understands the foregoing.

Types of Touch Screen Monitor 45

Types of the Touch Screen monitor

In total, several types of touch panels are known today. Naturally, each of them has its own advantages and disadvantages. We distinguish the main four designs:

  • Resistive
  • Capacitive
  • Projected Capacitive
  • With the definition of surface acoustic waves

In addition to these screens, matrix screens and infrared are used, but due to their low accuracy, their scope is extremely limited.

Resistive touch screen monitor

Resistive touch panels are among the simplest devices. At its core, such a panel consists of a conductive substrate and a plastic membrane with a certain resistance. When a membrane is pressed, it closes with the substrate, and the control electronics determines the resistance that arises between the edges of the substrate and the membrane, calculating the coordinates of the pressure point.

The advantage of a resistive screen monitor is its cheapness and simplicity of the device. They have excellent resistance to pollution. The main advantage of resistive technology is its sensitivity to any touch: you can work with your hand (including gloves), a stylus (pen) and any other hard blunt object (for example, the upper end of a ballpoint pen or the corner of a plastic card). However, there are also quite serious drawbacks: resistive screens are sensitive to mechanical damage, such a screen is easy to scratch, therefore, a special protective film protecting the screen is often purchased. In addition, resistive panels do not work very well at low temperatures, and also have a low transparency – they pass no more than 85% of the display’s luminous flux.

  • Communicators
  • Cell Phones
  • POS terminals
  • Tablet pc
  • Industry (control devices)
  • Medical equipment


Capacitive touch screen monitor

The capacitive touch screen technology is based on the principle that a large-capacity object (in this case a person) is able to conduct electric current. The essence of the capacitive technology is to apply an electrically conductive layer to the glass, and a weak alternating current is applied to each of the four corners of the screen. If you touch the screen with a grounded, large-capacity object (finger), current will leak. The closer the touchpoint (and therefore leakage) to the electrodes in the corners of the screen, the greater the leakage current, which is recorded by the control electronics, which calculates the coordinates of the touch point.

Capacitive screens are very reliable and durable, their resource is hundreds of millions of clicks, they perfectly resist pollution, but only those that do not conduct electric current. Compared to resistive, they are more transparent. However, the drawbacks are still the possibility of damage to the electrically conductive coating and insensitivity to touch with non-conductive objects, even with gloves on.

Types of Touch Screen Monitor 47

Projected Capacitive touch screen 

Projected capacitive screens are based on measuring the capacitance of a capacitor formed between a person’s body and a transparent electrode on a glass surface, which in this case is an insulator. Due to the fact that the electrodes are applied on the inner surface of the screen, such a screen is extremely resistant to mechanical damage, and taking into account the possibility of using thick glass, projection-capacitive screens can be used in public places and on the street without any special restrictions. In addition, this type of screen recognizes finger-gloved finger presses.

Payment terminal

These screens are quite sensitive and distinguish clicks with a finger and a conductive pen, and some models can recognize multiple clicks (multitouch). The projection-capacitive screen features are high transparency, durability, and immunity to most contaminants. The disadvantage of this screen is not very high accuracy, as well as the complexity of the electronics that processes the coordinates of pressing.

  • Electronic kiosks on the streets
  • Payment terminals
  • ATM
  • Laptop touchpads
  • iPhone


With the definition of surface acoustic waves

The essence of the touch panel with the determination of surface acoustic waves is the presence of ultrasonic vibrations in the thickness of the screen. When you touch the vibrating glass, the waves are absorbed, while the touchpoint is recorded by the screen sensors. The advantages of the technology can be termed high reliability and pressure recognition (unlike capacitive screens). Cons are weak protection from environmental factors, therefore screens with surface-acoustic waves cannot be used outdoors, and in addition, such screens are afraid of any pollution that blocks their work. They are rarely used.

Other, rarely used types of the touch screen monitor

  • Optical screens. Glass is illuminated with infrared light, as a result of touching this glass, the light scatters, which is detected by the sensor.
  • Induction screens. Inside the screen, there is a coil and a grid of sensitive wires that respond to touch with an active pen, powered by electromagnetic resonance. It is logical that such screens respond to clicks only with a special pen. Used in expensive graphics tablets.
  • Strain-gauge-type – react to screen deformation. Such screens have low accuracy but are very durable.
  • The infrared ray grid is one of the very first technologies to detect a touch on the screen. The grid consists of many light emitters and receivers located on the sides of the screen. It reacts to the blocking of the corresponding rays by objects, on the basis of which it determines the coordinates of pressing.


Using an induction screen in a laptop


  • A multi-touch that everyone is talking so much about and growing in popularity is not a type of touchscreen. At its core, multi-touch technology – which is a free translation of the multi-touch phrase – is an addition to the touch screen (most often built on the projection-capacitive principle), which allows the screen to recognize several points of contact with it. As a result, the multi-touch screen becomes capable of recognizing gestures. Here are just a few of them:
  • Move two fingers together – reduce image (text)
  • Spread two fingers apart – zoom
  • Flick with multiple fingers at the same time – scroll text, page in browser
  • Two-finger rotation on the screen – image (screen) rotation

About the benefits and disadvantages of touch screens

In handheld devices, touch screens have long appeared. There are several reasons for this:

  • Ability to make the minimum number of controls
  • Graphical interface simplicity
  • Ease of control
  • The efficiency of access to device functions
  • Enhancing Multimedia Features

However, there are more than enough disadvantages:

  • Lack of tactile feedback
  • Frequent need to use a pen (stylus)
  • The possibility of damage to the screen
  • Fingerprints and other dirt on the screen
  • Higher energy consumption

As a result, it is not always possible to completely get rid of the keyboard, because it is much more convenient to type text using the usual keys. But the touch screen is more interactive, thanks to a faster access to menu items and settings of modern gadgets.

We hope that this material will help you when choosing a device with a touch screen monitor.



In recent years, new information technologies have been developing rapidly, which make it possible in a short time to satisfy most of the virtual needs of customers in the service sector in various fields of activity. The introduction of new touch terminals allows you to instantly receive the necessary information and display it on the screen. Such innovative solutions became possible after the creation of unique touch terminals, which are multifunctional devices.


The nature of the interaction between man and machine has always been an attractive area in the field of obtaining complete information in any area of ​​human life. And now, due to the efforts of geniuses-programmers and design engineers, it was possible to create a unique product that is characterized by a high reaction rate to any request submitted “from outside”, and instantly display the requested information on the touch screen monitor.



A touch screen terminal (also called an interactive terminal or an interactive kiosk) is a combination of advanced computer developments connected in a hardware device that automatically receives information for a wide range of people.

The touch terminal operates in automatic mode. These devices can easily be found at airports, at railway stations, at subway stations, in shopping centers. In recent years, street sensor terminals have begun to appear.

The touch terminal is a multifunctional device that consists of several main components. The main one is an advanced computer filling, which is responsible for fulfilling user requests and displaying the information received on the screen. In addition to the computer, the terminal is equipped with other equipment – a barcode scanner, bill acceptor, audio system, etc. The screen is a regular monitor, which can be found at home or at workplaces of office employees. The case made of durable steel alloys provides reliable protection against hacking or damage, being a modern method of anti-vandal protection. Each component of the touch terminal provides a specific function, thereby expanding the capabilities of citizens in obtaining information that is characterized by relevance and reliability. The sensor function is the most advanced method of interaction between the user and the device. By clicking on the on-screen buttons, the device instantly receives the information necessary for work, starts analyzing it and creates a request, on the basis of which information that is important to the user will be received in the future and displayed on the screen for terminals.


Each terminal uses the latest software, regularly updated, which allows you to increase the range of services offered and expand the interface with additional management tools that facilitate the user’s work.



The presence of a huge number of advantages from the use of an information terminal with a touch screen can not cause any doubt. Their benefits are dictated by time and the development of consumer IT systems. Any terminal is characterized by the following list of advantages:

  • The information terminal is characterized by increased performance; it works around the clock;
  • It replaces the work of professional consultants, thereby reducing salary costs, tax deductions, etc. In addition, the possibility of interactive interaction between the user and the device allows you to free staff who can now be sent to solve more important problems;
  • The case is ergonomic, has a pleasant appearance, is reliably protected from vandal actions and hacking attempts;
  • There is the possibility of being equipped with special equipment, which greatly expands the functions of the touch terminal;
  • An intuitive interface that anyone can understand, even one who is far from computer technology;
  • The latest technologies in the field of touch displays allow you to give a clear and vivid picture, facilitating the process of perception of information;
  • The device can be used almost everywhere;
  • Connecting to a single network allows remote administration of the system;
  • The simplicity of the interface reduces the risk of failure of the interactive terminal due to errors made by users;
  • Regular updating of the software used increases the protection of the system and positively affects the information received during the work.



Using the latest computer technologies allows you to expand the capabilities of touch terminals, using them to perform the following tasks:

  • Obtaining comprehensive information on the product or service of interest;
  • Extracting information of any type (text, audio, video, etc.);
  • Ability to print checks, receipts, etc.;
  • Acceptance of fees for utilities and other types of services.

Very often, terminals with touch screen monitor have the ability to switch the display language of information, which extends the reach of users. In addition, manufacturers take care of users with physical disabilities. For example, for people traveling in wheelchairs, the monitor is located at a level convenient for them. People suffering from hearing loss will benefit from a specially designed induction panel. It will be easier for poorly seeing users to perceive information due to the function of increasing the font.


To understand what are the uses of touch terminals, it is necessary to clarify all the possible areas of their operation and applications. These hardware devices today have huge development prospects. They occupy the market segment that is constantly being improved. Since the main consumer of any services is civil society, it is important to bring to each user information about any changes at the legislative level, about the rules and technical regulations regarding all types of services. This task in real time can be performed by information terminals, which are characterized by the absence of a human factor, which in the future can lead to various negative consequences. With the development of the market of terminals with touch screen monitor, it will be possible to document the interaction of users and bodies that provide information. It will have the following form: a request for information – printing an invoice, paying it – printing a receipt – recognizing bonus cards – activating discount coupons.


  • In shopping centers, supermarkets and other institutions engaged in trade. They are used as an alternative method of payment for purchases, as well as to obtain comprehensive information on goods. The use of info terminals allows you to reduce financial costs and automate the process of selling products;
  • In entertainment establishments, for example, night clubs;
  • In institutions providing public services to the public (single window of public services, MSO – municipal services office) based on the requirements of the company informational support program, designed for 2011-2020;
  • In the field of tourism services. Very often tour operators use touch terminals in places with high traffic, for example, in shopping centers. The screens show colorful photographs and videos of exotic countries, as well as information about promotions and discounts. Thus, travel agencies are trying to create a stir around the possibility of a good rest for a low fee;

  • In hotels to provide visitors with important information, as well as expand opportunities in the field of room reservation;
  • Often, terminals with touch screen monitor play the role of virtual storefronts, which display the basic information on the product – image, description, price, etc. This approach can be found in numerous fast food restaurants;
  • Information touch terminals are often used by advertising companies. They are installed in crowded places (most often these are shopping centers). Advertising videos are played on their screen or other types of advertising information are displayed.


The wide capabilities of touch terminals allow their use in any area of ​​human activity. They perform various tasks: from simple informing to accepting payment for goods and services. It is multitask capability that has become the main reason for the high demand for information terminals.


According to enterprises that have implemented touch terminals in the customer service process, 57.8% of users of such equipment are men, most of whom already have experience with such equipment 48.6% of users who use info terminals to obtain any information are young people whose age does not exceed 30 years.

According to statistics, after installing the terminals, in the first month about 20% of customers use its services. After 2-3 months, this figure rises to 80%. These data directly indicate the demand for touch terminals in various fields of activity.

How do touch screen monitor work?

How do touch screen monitor work?

We talk about how the simplest way to interact with electronics is arranged – a touch screen.


iPhone 2G was the first mobile phone, the management of which was completely based on interaction with the touch screen. More than ten years have passed since its presentation, but many of us still do not know how the Touchscreen works. But we are faced with this intuitive input tool not only in smartphones, but also in ATMs, payment terminals, computers, cars and airplanes – literally everywhere.

touch screen monitor


Prior to the touch screen monitor, the most common interface for entering commands into electronic devices was various keyboards. Although it seems that they have nothing to do with touchscreens, in fact, how much the touch screen is similar to the keyboard according to the operating principles may surprise. Let’s look at their device in detail.

The keyboard is a printed circuit board on which several rows of switch buttons are installed. Regardless of their design, membrane or mechanical, the same thing happens when each key is pressed. An electric circuit is closed under a button on a computer board, the computer registers the passage of current at this point in the circuit, “understands” which key is pressed, and executes the corresponding command. In the case of the touch screen, almost the same thing happens.


There are about a dozen different types of touch screens monitors, but most of these models are either outdated and not used long ago, or are experimental and are unlikely to ever appear in mass-produced devices. First of all, I will talk about the device of relevant technologies, those of which you constantly interact with, or at least may encounter in everyday life.

Resistive touch screen monitor

Resistive touch screens were invented back in 1970 and have not changed much since then.

In displays with such sensors, a pair of additional layers is located above the matrix. However, I’ll make a reservation, the matrix is ​​not obligatory here. The first resistive touch devices were not screens at all.

How do touch screen monitor work? 55


The lower sensor layer consists of a glass base and is called a resistive layer. A transparent metal coating is applied to it, which transfers the current well, for example, from a semiconductor such as indium tin oxide. The top layer of the touchscreen with which the user interacts by tapping the screen is made of a flexible and elastic membrane. It is called a conductive layer. An air gap is left in the space between the layers, or it is evenly strewn with microscopic insulating particles. Four, five or eight electrodes are connected to the sensor layer along the edges, connecting it with sensors and a microcontroller. The more electrodes, the higher the sensitivity of the resistive touchscreen, since the voltage change on them is constantly monitored.

Here’s a resistive touch screen on. Nothing is happening yet. An electric current flows freely through the conductive layer, but when the user touches the screen, the membrane bends from above, the insulating particles part, and it touches the lower layer of the touchscreen, makes contact. This is followed by a change in voltage at once on all electrodes of the screen.


The touchscreen controller detects voltage changes and reads readings from the electrodes. Four, five, eight meanings and all are different. The microcontroller will calculate the X-coordinate of the pressing by the difference in the readings between the right and left electrodes, and by the differences in the voltage on the upper and lower electrodes, it will determine the Y-coordinate and, thus, tell the computer the point at which the layers of the touch layer of the screen are in contact.

Resistive touch screens boast a long list of shortcomings. So, in principle, they are not able to recognize two simultaneous clicks, not to mention a larger number. They behave badly in the cold. Due to the need for a layer between the sensor layers, the matrices of such screens noticeably lose in brightness and contrast, tend to glare in the sun, and generally look noticeably worse. Nevertheless, where image quality plays a secondary role, they continue to be used because of their resistance to pollution, the ability to use gloves and, most importantly, low cost.

Such input tools are universally mounted in low-cost mass devices, such as information terminals in public places, and are still found in outdated gadgets, such as cheap MP3 players.

Infrared touch screen

The next, far less common, but, nevertheless, relevant version of the touch screen is an infrared touchscreen. It has nothing to do with a resistive sensor, although it performs similar functions.

How do touch screen monitor work? 57


The infrared touch screen is constructed from arrays of LEDs and photosensitive photocells located on opposite sides of the screen. LEDs illuminate the surface of the screen with invisible infrared light, forming on it something like a web or grid. This resembles a burglar alarm, which is shown in spy action films or computer games.

When something touches the screen, it doesn’t matter if it’s a finger, a gloved hand, a stylus, or a pencil, two or more rays are interrupted. Photocells record this event, the touchscreen controller finds out which of them receive infrared light and, by their position, calculates the area of ​​the screen in which the obstacle occurs. The rest is to compare the touch with which interface element is on the screen in this place – the software task.


Today, infrared touch screens can be found in those gadgets whose screens have a non-standard design, where adding additional touch layers is technically difficult or impractical – in e-books based on E-link displays, for example, Amazon Kindle Touch and Sony Ebook. In addition, because of simplicity and maintainability, devices with similar sensors liked the military.

Capacitive touch screen

If the computer registers a change in conductivity following a tap on the screen directly between the layers of the sensor in resistive touchscreens, then capacitive sensors record the touch directly.

How do touch screen monitor work? 59


The human body, skin are good conductors of electricity and have an electric charge. Usually, you notice this by walking on a woolen carpet or taking off your favorite sweater, and then touching something metallic. We are all familiar with static electricity, have experienced its effects on ourselves, and have seen tiny sparks bursting from our fingers in the dark. The weaker, inconspicuous exchange of electrons between the human body and various conductive surfaces occurs constantly and it is precisely this that capacitive screens fix.

The first such touchscreens were called surface-capacitive and were a logical development of resistive sensors. They have only one conductive layer, similar to the one used previously, installed directly on top of the screen. Sensitive electrodes were also attached to it, this time around the corners of the touch panel. Sensors monitoring the voltage at the electrodes and their software were made much more sensitive and could now detect the slightest changes in the flow of electric current across the screen. When a finger (another current-conducting object, for example, a stylus) touches a surface with a surface-capacitive touch screen, the conductive layer immediately begins to exchange electrons with it, and the microcontroller notices this.

The appearance of surface-capacitive touchscreens was a breakthrough, but due to the fact that the conductive layer applied directly on top of the glass was easily damaged, they were not suitable for new generation devices.

To create the first iPhone, projection-capacitive sensors were required. This type of touchscreen quickly became the most common in modern consumer electronics: smartphones, tablets, laptops, all-in-ones and other household devices.

The top layer of the screen with a touchscreen of this type performs a protective function and can be made of tempered glass, for example, the famous Gorilla Glass. Below are the finest electrodes that form a grid. At first, they were superimposed on top of each other in two layers, then they began to be placed on the same level to reduce the thickness of the screen.


Made of semiconductor materials, including the already mentioned indium tin oxide, these conductive hairs create an electrostatic field at their intersections.

When the finger touches the glass, due to the electrical conductive properties of the skin, it distorts the local electric field at the nearest intersections of the electrodes. This distortion can be measured as a change in capacitance at a single grid point.


Since the array of electrodes is made quite small and dense, such a system is able to track the touch very accurately and without problems captures several touches at once. In addition, the absence of additional layers and interlayers in a sandwich made of a matrix, a sensor and a protective glass positively affects the image quality. However, for the same reason, broken screens, as a rule, are completely replaced. Once assembled together, a screen with a projection-capacitive sensor is extremely difficult to repair.

Now the advantages of projective-capacitive touchscreens do not sound like something surprising, but at the time of the presentation of the iPhone they provided tremendous success, despite objective disadvantages – sensitivity to pollution and humidity.


Pressure Sensitive Touch Screens – 3D Touch

The original predecessor of pressure-sensitive touch screens was Apple’s proprietary technology called Force Touch, which was used in the company’s smartwatches, MacBook, MackBook Pro and Magic Trackpad 2.

Having tested on these devices interface solutions and various scenarios for the use of pressure recognition, Apple began to introduce a similar solution in its smartphones. In the iPhone 6s and 6s Plus, recognition and measurement of pressure has become one of the functions of the touchscreen and has received the commercial name 3D Touch.

Although Apple did not hide the fact that the new technology only modifies the usual capacitive sensors and even showed a scheme that outlined the principle of its operation, details about the device of touch screens with 3D Touch appeared only after the first new-generation iPhones were dismantled by enthusiasts.


In order to teach the capacitive touch screen to recognize pressures and distinguish several degrees of pressure, the Cupertino engineers needed to rebuild the touch screen sandwich. They made changes to its individual parts and added another new layer to the capacitive one. And, interestingly, when doing this, they were clearly inspired by obsolete resistive screens.

The grid of capacitive sensors remained unchanged, but it was moved back closer to the matrix. An additional array of 96 separate sensors was integrated between the set of electrical contacts that monitor the place of touching the display and the protective glass.

Its task was not to locate a finger on the iPhone screen. The capacitive touchscreen still did a great job with this. These plates are necessary to detect and measure the degree of bending of the protective glass. Apple specifically for the iPhone ordered Gorilla Glass to design and produce a protective coating that retains its original strength and, at the same time, is flexible enough to allow the screen to respond to pressure.

On this development, it was possible to finish the material telling about touch screens, if not for another technology, which several years ago had a great future.

Wave touch screens

Unexpectedly, but they do not use electricity and do not even have anything to do with light. Surface Acoustic Wave system technology uses surface acoustic waves that propagate along the surface of the screen to determine the point of contact. The ultrasound generated by the piezoelectric elements in the corners is too high for the human hearing to catch. It spreads back and forth, repeatedly reflected from the edges of the screen. Sound is analyzed for anomalies created by objects touching the screen.


There are not many disadvantages in wave touch screens. They begin to make mistakes after severe contamination of the glass and in conditions of strong noise, but at the same time, in screens with such a sensor there are no additional layers that increase the thickness and affect the image quality. All sensor components are hidden under the display frame. In addition, wave sensors can accurately calculate the area of ​​contact of the screen with a finger or other object and indirectly calculate the force of pressing the screen from this area.

We are unlikely to encounter this technology in smartphones due to the current fashion for frameless displays, but several years ago Samsung experimented with the Surface Acoustic Wave system in monoblocks, and panels with acoustic touchscreens are sold as accessories for gaming machines and advertising terminals. now


Instead of a conclusion

In a very short time, touchscreens have conquered the world of electronics. Despite the lack of tactile response and its other drawbacks, touch screens have become a very intuitive, understandable and convenient method of entering information into computers. Last but not least, they owe their success to a variety of technical implementations. Each with its own advantages and disadvantages, suitable for its class of devices. Resistive touch screen monitor for the cheapest and most popular gadgets, capacitive screens for smartphones and tablets and desktop computers with which we interact every day and infrared touchscreens for those cases where the screen design should be left intact. In conclusion, it remains only to state that touch screens are with us for a long time, no replacement is expected in the near future.

Technology impacting the future

I believe technology today has definitely impacted the future and especially in my career of dentistry. The new kinds of technology has enhanced the quality of dental work and easies patient’s discomfort. Social media has also played a key role in free marketing and dentists have been taking full advantage of it. When I went to get my x-ray license at school, we were taught how to develop each x-ray shot we took and the process of developing these x-rays would take 15-20 minutes.

Today, in almost all dental practices, when digital x-rays are taken, it shows up immediately on the computer screen for quicker diagnoses. This lessens the time patients have to wait in the chair and allows them to go about their day. In addition to x-rays, I have had the privilege of working as a dental assistant for a dentist who used a cerec machine. The cerec machine allowed the dentist to create the crown for a crown prep that same day. This makes for a quicker procedure and the patient does not need to come back after 2 weeks to receive his/her crown.

The cerec machine only takes a few minutes to create the crown as well. As a dental assistant, I would notice all of the technology that has developed since the beginning stages of dentistry, from the amalgamator, autoclave, drills, touch screen and all of the other devices that has made dentistry where it is today. When I recently had my wisdom tooth removed, I had a CT scan performed to develop a radiograph of my entire skull and all of the nerves that aligns with my jaw.

My wisdom tooth removal was a special case, in that the tooth was sitting on top of my facial nerve. This particular radiograph allowed the oral surgeon to determine the best way of removing the wisdom tooth because if there was a slight mistake, I could lose function of the lower part of my jaw. The CT scan did wonders in allowing me to have a seamless procedure. In the near future, I do not see technology-replacing dentists, only because dentists are able to adapt to different scenarios and dentists are also compassionate and patient health clinicians. Dentists do have the patient’s best interest in mind, when diagnosing and treating.

I also see most offices going paperless in the more modern dental practices. Technology and dentistry has been fascinating to observe and I only expect more types of technologies to ease patient’s discomfort. 

I also believe social media has been a huge leap forward in free marketing of dental practices. Dentists are able to post pictures of their practice, before and after cosmetic procedures, as well as technological advances to help ease the worries of patients, who are scared to go to the dentist.

I believe in today’s generation, yelp and Google have played huge roles in identifying great dentists in the area. This is based on people’s reviews and from my own personal experience of using amazon, I tend to purchase items that have the best reviews, for the sake of having to try products I am not familiar with. Instagram for example has played a huge free marketing tool that dentists can utilize.

Dentists post pictures of there practice, employees, before and after shots, as well as they can post videos that last a couple seconds. This can bring about a vibrant and entertaining page that can draw lots of traction from people all over the world. It is fascinating to see dentists have thousands of followers on instagram. These thousands of followers are potential patients. Instagram also allows you to post videos that can show up on your story as well. Stories are videos that anybody can see for up to 24 hours and after those 24 hours the stories disappear, unless you decide to save them.

Facebook also allows you to create a personal page for your practice. People are able to write reviews, they can send you direct messages, but also see posts and videos you want to share. These types of free social media is what revolutionizes dentistry in today’s age. In the near future, I see technology always improving, starting from light cures, impression material, more precise hand pieces, loupes and everything else. 

When I was five, I remember spending time watching my father build my first aircraft model. I watched him cut, paste and paint the meticulously. My father lovingly shared his passion with me as we built planes together. Since then, I followed my father in sharing his hobbies. Whether it was sketching, playing musical instruments, or building model airplanes, my father fostered discipline and perseverance as I honed my hand dexterity.

These are my most cherished moments now that he is gone. My dad suffered from diabetes and due to poor oral hygiene had lost all his teeth. Dentures however gave him new life so visible when he smiled. It is this memory that still motivates me to pursue dentistry in hopes of changing others’ lives by giving them the ability to smile.

In addition to being competent at diagnosing and treating patients, compassion is critical for a clinician. Growing up I witnessed my mom as a caretaker in both her job and at home and I too was draw to patient care of a patient with Alzheimer’s disease; this experience has helped me to develop patience and empathy towards others who cannot care for themselves. I understand more fully that as a future dentist it is important to identify and treat discomfort with skill but also to provide care with compassion to each patient.

During the time I shadowed Dr. Abello, I learned how successful dentists care for their patient’s oral health as well as their physical and emotional well-being. She modeled the dentist I hope to become by combining quality clinical care with compassion and patience. The way she genuinely listened to her patients’ concerns and kindly addressed each one with reassurance earned her their trust and soothed their worries. Most of all, her respect towards each patient and her readiness to help others truly showed when she developed personalized treatment plans for each patient. Dr. Abello understood that each patient was different and offered treatment options that best fit their needs. Like Dr. Abello, I want to become the kind of dentist who dedicates my time to serving others with compassion and humility by always having the patient’s best interest in mind.

Knowing my strong desire to become a dentist and that my academic credentials were weak, I enrolled in Boston University’s Oral Health Sciences Master’s Program to strengthen my credentials for the rigor and challenges of dental school. Even though my path to dentistry has not been traditional, I now feel prepared. Obtaining my Master’s has given me the confidence and the skills necessary to succeed in dental school and allowed me to learn more about the systemic effects connecting oral and systemic health. Having lost my father to diabetic complications, I know that as a future dentist I can better educate others on the importance of maintaining oral health.

As a practitioner, it is vital to provide the utmost care when treating patients, and more importantly, to be able to connect with patients to gain their trust and respect. Dental school will provide me with the scientific foundation to better the oral health of those in need while also allowing me to achieve my dream of creating life-changing smiles. If given the privilege to study and train to become a dentist, I will work diligently to serve my community by educating people on the importance of maintaining oral health. I also know that through my skilled hands and my passion for patient care I will help to create smiles that change people’s quality of life.

My father passed away when I was 15 years old and I had to work to help provide for my family and my grades suffered as a result. I was unmotivated and when I went to community college, I had to learn from my mistakes through trial and error. I decided to pursue dentistry at the age of 21 and I transferred to UCI, where I obtained my BS in Public Health Sciences. At UCI, I lacked the science foundation most of the other students had. It was here where I was also diagnosed as pre-diabetic. This news really put me in a depressed state because I had anticipated the same fate that happened to my father would happen to me. My grades suffered and by the time I applied to dental school, my numbers were not cutting it. After graduating in 2015, I decided to do an informal post-bac and take science classes at my local state school to increase my science GPA in hopes of getting accepted to a master’s program. After doing the post-bac, I was accepted at Boston University, where I obtained my MS in Oral Health Sciences. By this time, I had already applied to dental school 4 times without success. My journey consisted of 7 years of undergrad, 1 year of post-bac, 2 years of a master’s program and having to retake the DAT’s twice. This year I was accepted at Roseman University of Health Sciences, where I will be pursuing my dental degree. I never gave up on my passion and every year I did my best to improve my application and my journey has humbled me and I am truly blessed by it.

My primary goal for going to school is to pursue dentistry. I lost my father at the age of 15 due to progressed type 2 diabetes. My father had periodontal disease and had lost all of his teeth. Dentures redefined the quality of his life by giving him that ability to smile. As a dentist, it is my passion to be able to educate others on how important it is to maintain your oral health and how much of a connection your oral health has with your systemic health. I also have a passion for people through my experience working as a caretaker for physically disabled patients and a patient with Alzheimer’s Disease. My compassion and patience are deeply rooted from these experiences but also because of my faith. Dentistry allows me to use my hands to better serve people. I grew up building model aircraft planes with my father, and played the piano and guitar. I plan to work diligently to serve my community by educating people on the importance of maintaining oral health. Through my skilled hands and my passion for patient care I will help to create smiles that change people’s quality of life. 

I believe that social responsibility is an act of a responsibility to benefit society at large. I believe strongly that clinicians, including dentists are held to a higher standard and its critical to always share my skills with those in need. It is a passion of mine to be able to volunteer in my community and especially with the homeless. I believe as a future clinician, social responsibility consists of competence, fairness, integrity, responsibility, respect and service-mindedness. It is your responsibility to be a lifelong learner, to give your best effort to each and ever patient, treating them in a fair manner. Integrity to treat each patient as if they were a family member. Being responsible to show up on time, being dependable, having a plan for patients of record who have an emergency and by admitting mistakes. It is important to have respect for your patients by maintaining confidentiality of health information, protecting patients from harm, respecting there right to choose their course of treatment within a correct standard of care parameter. It is also important to have service-mindedness and outreach to people who do not have access to quality dental work. 

I worked at a corporate dental office and I remember a story when I had a patient come in, who had previously been in a gang, got shot in the face and was a crystal meth user. I took his x-rays and treated him like I treat every patient, with compassion and patience. As I took this patient to an operatory, he pulled me aside and said “Patrick, thank you for treating me like a person” and this touched me because I could not have imagined treating anybody any different and social responsibility to me is treating patients as people first. This is the reason why technology will not replace dentists. Dentists always have a patient’s best interest in mind and they treat patients as people first, something technology can never do. 

The 7 facts you need to know about Resistive touch screen.

Resistive touchscreens used to play a very important role in touchscreen filed. Even though most of the market shares have been occupied by PCAP touchscreen and foldable touchscreen foil nowadays, but still there is an irreplaceable status in some of the applications for resistive touchscreen. below let’s try to reveal the 7 features of the resistive touch screen.

The 7 facts you need to know about Resistive touch screen. 61
  1. Work Through Pressure

Unlike other types or touchscreens, Resistive touchscreen works through pressure. It consists of 2 layers, Normally the Top layer is ITO Film and bottom layer ITO glass which separately by the dot in between. When you press the ITO film in the surface, which will make the ITO FILM and ITO glass contact .then the touchpoint creates. That’s is how resistive touchscreen works.

2. Can be touched by any objects, except sharp stuffs

Because of the feature of its working principle. resistive touchscreen can be touched by any objects like pen, fingers stylus, gloves etc , but you can not use the sharp objects to touch, as the touch surface is the ITO film which is easy to scratch. And when its scratched or broken will actually affect the touch effect.

3. Sensibility 

Resistive touch screen is less sensible Compare with Pcap touchscreen. As resistive touch panel work by touch ,so sometimes if you press lightly, it may be unable to fell the touch and cause the touch sensibility not so sensible .

4. Single Touch 

Resistive touchscreen can only support single point touch. Which Pcap touchscreen can support 10 point multi touch screen.

5. Calibration Needed :

Resistive touchscreen calibration principle: the resistance value of conductive ITO layer and the whole circuit will be slightly offset with time and voltage, etc. In order to more accurately correspond with the functional pattern on the LCD display screen, the standard position shall be recalibrated and calculated. Without calibration may cause linear offset

6. Available size : 

Resistive touchscreen standard size range is from 3.5” to 22” which because of the raw material limitation so no bigger size available.

7.Dustproof & water proof 

Resistive touchscreen is waterproof and dustproof, which is a very good application for outdoor and rough situation use.

Review TFT Display. Benefits of TFT Display

Today the world is moving so fast in terms of science and technology. Every second, a new discovery is taking place all over the world in the column of computers and mechanization. Despite new discoveries, there are also ongoing processes for improving old technologies, touch screen mobile phones and digitalized trends. “TFT” Display is one of the latest innovation which helps to improve old display devices. The full abbreviation of TFT is “thin film transistor”. For our customers, we have gathered the most convenient and important information about TFT displays. Below you can find the desired information and knowledge about TFT displays and our products.

TFT Display

What is TFT Display and Working of TFT Display

As mentioned above TFT full form is “thin film transistor. This TFT display technology enhances the picture and color quality of old LCD Displays and monitors. The LCD screens use a crystal form of liquid which is used to display pictures to the spectator. The small transistors in a TFT LCD display increase the number of pixels. These transistors increase the number of pixels when LCD displays low-quality images due to the slow rate of fluid movement. The slow fluid movement usually causes blurry images in LCD which can be solved by using TFT transistors. TFT displays are nowadays used in home appliances, medical equipment, engineering instruments, airplanes computer devices, and TVs.

“Thin film transistor display” uses a range of complicated scientific and electronic properties which creates a high-resolution image on the screen. TFT display takes advantage of electrical energy. That electrical energy causes the liquid display to change its molecular arrangement. When the molecular structure of liquid display has changed, waves of light starts to pass through it using high speed. The mechanism of TFT display remains inconsistent flow, refreshing and changing again and again. It remains in the same consistent flow at the same speed until the signals have not been stopped, coming from a control device.

The board of TFT display uses many layers of filters, placed between two panes of glass. TFT board utilizes three/five different filters and layers determine how much light and which colors are being passed. These three or five filers and layers contain polarizer filters, color filters and different types of alignment layers. Several pixels of a TFT display is dependent on the depth of color matrix, TFT display structure, and mechanism. And of course, a higher number of the pixels in TFT display, higher the image quality and detail. Working on a TFT display also depends that what screen size and several pixels you choose for your TFT LCD display.

Advantages of TFT Display

There are uncountable and unique advantages of TFT LCD displays but for your information, some of are the following:

1. TFT displays are very famous for their amazingly clear, sharp and vivid colors. It will not be hesitating to say that this TFT technology displays colors and images extraordinary sharp and exquisite!

The 2 main Touchscreen bonding Technologies. Resistive touch screen manufacturers

As we all know, the bonding method for common TFT LCD and touch screen on the market are divided into two ways: Air bonding and Direct bonding. If a person who doesn’t understand these two terms certainly doesn’t know the difference between them, or what kind of advantages and disadvantages they all have, let’s briefly explain below:

The 2 main Touchscreen bonding Technologies. Resistive touch screen manufacturers 75

Direct Bonding features: resistive touch screen manufacturers

Directly bonding is a way bonding protect glass, TFT LCD and Touchscreen completed together in a seamless way, omitting the air layer existing between the display screen and the touch screen, making the screen thickness thinner. The visual effect is perfectly presented, it looks more beautiful, reduces the chance of getting into the gray, the picture is more transparent which enhances the display effect, and makes the screen thinner. It seems that the direct bonding is more aesthetic and practical. However, the direct bonding technology yield is lower , the cost is relatively expensive, and once damaged, the entire screen needs to be replaced. Resistive touch screen manufacturers

Air Bonding Features:

What about the air bonding then? The air bonding is to use double-sided tape to fix the touch screen and the four sides of the display panel, and there is a gap between the display panel and the touch screen with air filling, the operation is relatively simple, and the process is relatively mature. Mature technology plus stable yield rate gives the biggest advantage of air bonding, as well as cheaper and simpler replacement. It also has a feature that the screen is thick and the overall body cannot be thin. There are gaps, and dust is the biggest enemy that exists. In addition, the reflective surface of the panel and the glass are more obvious, and the display effect is relatively poor.

Through the above content, I believe that everyone understands the difference between the two bonding methods. compare with air bonding the direct bonding is much more better from the display effect, to the appearance of the screen, and the gap dust,

Eagle Touch as one of a resistive touch screen manufacturers in China, manufacturing Resistive 4 wire touch screen ,5 wire touchscreen as well as PCAP touchscreen, we provide both air bonding and direct bonding .

Types of Touch Screen- Touch screen manufacturers

There are four main types of touch screen technology that includes resistive, capacitive, SAW and infrared. Let’s explore them in detail.

1) Resistive touch screen – From the name, you can gain the idea that it has a resistive touch. Resistive touchscreen panels are composed of distinct thin layers. The screen works by applying pressure onto it. This touchscreen comes in different models like 4 wired and 5 wired resistive screens. Today 6, 7 and 8 wired resistive screens are also available. The outer layer of the screen is flexible and coated inside while the bottom layer is made rigid. And between them, there is a gap containing insulating spacer dots. When someone presses the top layer then both of the layers touch and gets connected.

• The applications of resistive touch screen included in the restaurant, control panels, industrial automation, voting terminals, POS (point of sales), etc.

• One of the advantages of using this touch screen technology is that it consumes less power and aren’t expensive.

• You can use stylus, pen or even gloved hand to activate the screen. The only disadvantage is the low image clarity that it provides in comparison to the other touch screen technologies.

• Additionally, the outer film is made of polyester that can get damaged by scratching, poling or coming in contact with sharp objects.

2) Surface Acoustic Wave- SAW technology works because of ultrasonic waves. The problem with using this touch screen is that it is easily damageable by the elements present outside. Contaminants can also affect the proper functioning of the touchscreen functionality. Piezoelectric transducers in series and receivers are used. These are present on the side of a monitor’s plate that produces invisible ultrasonic waves on the surface. When someone touches the panel then a portion of a wave is absorbed. With the help of the receiving transducer, the touch point is located and the data is sent to the computer. There are some important benefits of using SAW.

• It is highly scratch resistant than the capacitive touch screens.

• It provides extremely good image clarity.

• It can’t be operated with hard materials like a pen.

• Any amount of water when fall on it will cause false-triggering.

• The screen can stop working at those points where solid particles are residing.

3) Capacitive- Capacitive touch screens are of two types including surface and PCAP (Projected Capacitive). It contains an insulator like glass. This glass is then coated with a transparent conductive material like ITO (indium tin oxide). In projected capacitive, artificial intelligence is used that enables accurate sensing with the help of thick glass. It was first made by Ronal and Malcolm Binstead in 1984. They invented a capacitive touchpad containing 16 key. The PCAP can be operated by the gloves of cotton or surgical gloves. People can input data using two fingers at the same time (multi-touch). ). In the market, surface capacitive is the second most popular touchscreen panel. These panels consist of a transparent electrode layer placed on top of a glass panel. It is then covered by a protective layer. The screen reacts to the static electrical capacity of the human body when touched. Do you know by using a touch screen foil (PCAP touch technology), you can change any acrylic and glass surface into a touch screen?

4) Infrared- Infrared involves the use of IR emitters (X-Y infrared LED) and photodetector pairs. An invisible grid of light is created across the screen that results in the production of a high-quality image.

Hardware Features

After knowing everything about the touch screens, your next step will be to find the correct hardware according to the business needs and of course a touch screen manufacturer that will meet your needs… How much space do you need on the touchscreen? If you have the answer to this question then that’s great. To run your business effectively and efficiently, hardware features matters a lot.

• The cable management should be done properly in the hardware.

• Serial, as well as a USB touch interface, are there are working properly.

• There must be hidden place in the base of the hardware for an external power supply.

• The hardware must be able to display MSR.

• The hardware should also show rear customer options.

Features to consider while choosing the touch screen panel

Every touch screen has pros and cons. A touch screen suitable for one place can have no use at the same place. Thus, your selection should consider hardware features, touchscreen size, touch accuracy, resolution, timing in responding, clarity, life expectancy, environmental conditions, etc.

• Touch Size: Touchscreens comes in three sizes small, medium and large. The sizes of the monitor can vary from 3.5-inch to 52-inch in size. It is necessary to check the size of the touchscreen panel. Full-color TFT LSD (Thin Film Transistor Liquid Crystal Display) ranges from size 1.44 inch to 5.0 inch.

• Accuracy: The touch performance must be excellent and able to provide accurate touch response.

• Resolution: The resolution is the number of touch points on the touch panel. The greater the resolution, the higher will be touch points. Also, there’s another resolution known as pixel density. This should be considered too.

• Response: The touch panel must have the potential to respond quickly. The response time is measured in milliseconds (ms). According to a study, human being requires the latency of 10 ms or less than that for comfort. SAW screens respond quickly with the response time of around 10 ms and IR takes 20 ms.

• Clarity: Being at the top of the display, the quality of the image gets interrupted by the loss of light. Resistive screens the poorest in producing clarity in the image.

What’s Resistive Touchscreen? Resistive touch screen suppliers.

As there are more resistive touch screen suppliers on the market which make resistive touchscreens more popular and prices are falling down, so that resistive technology is becoming more widely used. In order to choose the best touch screen technology, application designers must consider the application requirements. Resistive touch screen technology requires only a simple printed circuit board design, unlike capacitive and inductive touch screen technology, which requires electrode or coil etch on the printed circuit board. Because the touch screen is directly overlaid on the display, so that the printed circuit board space required for mechanical switches or capacitive touch key electrodes can be saved. Resistive touch screens are not recommended for use in harsh environments, such as mines or work sites that are often exploding or dusty. Little damage on resistive touch screens can affect touch accuracy and linearity.

Resistive Touchscreen

1.The working principle of resistive touchscreen:

1. A resistive touch screen is a transparent glass panel with a surface covered with a touch-responsive film.

2. The resistive touch screen panel consists of two resistive layers (ITO) and separated by the dot in between.

3. The two thin film layers of the resistive touch screen form a resistor network that acts as a voltage divider for the touch position detection function.

4. The touch screen causes a voltage change on the voltage divider formed by the resistor network. This voltage is used to determine the contact position of the touch screen.

5. The touch screen controller (TSC) converts the captured analog voltage signal into a digital touch coordinate signal. A built-in analog-to-digital conversion channel acts as a voltmeter for measuring analog voltage.

6. After touching the screen, the touch controller functioning as a voltmeter first applies a voltage gradient VDD at the X+ point and a ground voltage GND at the X-point. Then, the analog voltage on the Y-axis resistance is detected, and the analog voltage is converted into a value, and the X-coordinate is calculated using an analog-to-digital converter. In this case, the Y-axis becomes a sensing line. Similarly, the Y coordinate can be measured by applying a voltage gradient at the Y+ and Y-points.

7. Some touch controllers also support touch pressure measurement, or Z-axis measurement. When measuring the Z-axis coordinates, a voltage gradient is applied to the Y+ axis and the X-axis.

 2.The 3 types of resistive touchscreen.

According to the number of sensing lines on the touch screen, the resistive touch screen can be further divided into three categories: 4-wire resistive touchscreens5-wire resistive touchscreens and 8-wire resistive touchscreens . The strip electrodes of the 4-wire touch screen are mounted on two different resistive layers (X+, X- are on the same layer, Y+, Y-the other resistive layer). The 5-wire touch screen has only round electrodes (X+, X-, Y+, and Y-) on the bottom layer. The top layer is used to measure the voltage during the touch process and the voltage gradient is applied only to the bottom layer.

The 8-line touch screen works like a 4-wire touch screen. Just add a reference voltage line to each line, so the final number of buses reaches 8. The new four lines are used to provide reference voltages to the original four lines. The 8-wire touch screen uses the measurement principle of a proportional measurement analog-to-digital converter.

Because of its low cost and simple touch sensing algorithm, 4-wire touch screens are widely used in low-end consumer electronics. 5 wire and 8-wire touch screens are used primarily for expensive high-end medical equipment and important industrial controllers. Eagle Touch as an experienced touch screen manufacturer we provided both 4 wire resistive touchscreens and 5 wire resistive touchscreens.

Touch screen performance comparison

The resistive touch screen works in an environment completely isolated from the outside world. It is not afraid of dust, moisture and oil. It can be touched by any object and is suitable for industrial control. The disadvantage is that because the outer layer of the composite film is made of film, too much force or sharp touch may scratch the touch screen which will be unable to work anymore.

The capacitive touch screen has a high resolution and a good light transmittance, which can well meet various requirements. This type of touch screen is common in public places. However, the capacitive touch screen uses the human body as an electrode of a capacitor. When a conductor is close to and a sufficiently large capacitance is coupled between the ITO working surface of the interlayer, the current flowing away causes a malfunction of the capacitive touch screen; There is no response when touched with gloves or a hand-held insulating object because of the increased insulation medium.

The infrared touch screen determines the touch position by measuring the on and off of the infrared light, regardless of the material of the transparent baffle selected for the touch screen (some have no baffles at all). Therefore, the use of a baffle with good light transmission properties, and anti-reflective treatment, can get a good visual effect. However, due to the limitation of the volume of the infrared emission tube, it is impossible to emit high-density infrared rays, so the resolution of such a touch screen is not high. In addition, since the infrared touch screen relies on infrared sensing to work, external light changes, such as sunlight or indoor lights, can affect its accuracy.

The surface acoustic wave technology is very stable, and the controller of the surface acoustic wave touch screen calculates the touch position by measuring the position of the decay moment on the time axis, so the accuracy is very high. The surface acoustic wave touch screen also has a third axis (z axis), that is, a pressure axis – the amount of power that the user touches the screen can be obtained by calculating the amount of attenuation at the attenuation of the received signal, which can be divided into up to 256 levels of force. The greater the power, the wider and deeper the attenuation gap on the received signal waveform. Of all the touch screens, only the surface acoustic wave touch screen has the ability to sense touch pressure.
