TOUCH SCREEN
Touch Screen has become very popular in our daily lives: cell phones, ATM’s, kiosks, ticket vending machines and more all use touch panels to enable the user to interact with a computer or device without the use of a keyboard or mouse. But did you know there are several uniquely different types of Touch Screens? The five most common types are: Resistive Wire Resistive, Projected Capacitive, SAW (Surface Acoustic Wave), and Infrared.
Eagle Touch Provides: 4 wire resistive touchscreen, 5 wire Resistive touchscreen and Projected Capacitive touchscreen.
