| | | 4-Wire resistive touch screen is the preferred solution for low cost applications. It consists of a | conductive bottom layer (ITO Glass or 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 | | coordinate X axis of the touch point can be detected by measuring the voltage the voltage value thru the | | top ITO layer and the coordinate Y axis of the touch point can be detected in the same way by changing | voltage input to the top layer's electrodes. |
