Product Description

5 Wire Touch Screen Working Principle:
5-Wire Resistive Touch Screen has the same structure as 4-Wire Resistive Touch Screen: Top layer, ITO film and bottom layer ITO film/glass. The bottom layer measures both X and Y coordinates and the top layer applies only voltage. When screen is touched, both conductive layers of the top film and bottom glass make an electrical contact. The controller will get the X and Y coordination by calculating the voltage of the touching point. Since the top layer only plays common sensor, the touch screen will be still working even the top film is damaged or scratched so the 5-Wire touch screen has longer life expectancy than 4-Wire touch screen.
