7 inch capacitive touch screen overlay
7 inch capacitive touch screen overlay consists of a conductive bottom layer of either glass or film and a conductive top film layer, separated by small, transparent spacer dots. A voltage is applied across the conductive surface. When pressure from a touch is applied to the top layer, it is deflected and makes contact with the bottom layer, which results in a voltage drop. This change is detected by the controller.
