How it works
|
|
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 layer's electrodes. The coordinate
X axis of the touch point can be detected by measuring 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.
