Principle of operation of Resistive TP-4099S2 Touchscreen

An insulator (dot spacer) is placed between the upper and lower ITO electrodes to prevent short-circuit between the electrodes when no input is made. Resistive TP-4099S2 touchscreens can be roughly divided into two types: analog type and digital (matrix) type.

Detects input position by load
When the TP-4099S2 panel is pressed, the upper substrate flexes and the upper and lower ITO electrodes (X/Y electrodes) contact and conduct each other to detect the input.
