What is 4wire Resistive Touch Screen
A 4wire resistive touch screen is a very simple touch sensor that uses dual layers of a flexible, conductive material that deforms under a touch and the layers make contact, the position of this contact is determined by the change in resistance of the circuits.
A 4wire type resistive uses 4 electrodes, one along each edge, and the touch controller alternates between sensing x and y axis readings using electrodes on opposite sides to carry a voltage difference and one of the adjacent electrodes to sense the touch.
