Overview
Action principle of the projected capacitive touch panel: There are two layers of glass in the lower surface of the ITO layer, the electric field formed X-axis and Y-axis, the electric field through the power lines to keep the glass surface electric field balance. Once the finger is close to the glass surface, and the finger electrode X or Y to form a new field, so that local changes in capacitance, the controller determines the position based on a change in capacitance.

Projected capacitive touch screen
Overview:
Action principle of the projected capacitive touch panel: There are two layers of glass in the lower surface of the ITO layer, the electric field formed X-axis and Y-axis, the electric field through the power lines to keep the glass surface electric field balance. Once the finger is close to the glass surface, and the finger electrode X or Y to form a new field, so that local changes in capacitance, the controller determines the position based on a change in capacitance. Capacitive touch screen with the traditional resistive touch screen is very different. Resistive touch screens at work, you can only judge a touch point, if two or more touch points, you can not make the right judgments, so resistive touch screen applies only to click on, drag the judge and some simple actions. The capacitive touch screen multi-touch, you can decompose the user's touch is collecting more signal and the decision signal significance of the two working to complete the complex movements of the judgment, while projected capacitive touch panel can sense light touch , better durability, light transmission rate up to 90%, high transmittance than the traditional resistive touch screen.
