4-wire resistive touch screen is the preferred solution for low cost applications.

It consists of a conductive bottom layer ITO Film and a conductive top layer (ITO Film).The two layers are suspended by many very small spacer dots

When a certain point is touched, the top layer contacts the bottom layer and a voltage charged by the controller is applied to the bottom layers electrodes.

The controller can detected the touch point by the position on the X and Y-axis.
