EE-0288-IN-AGH-AN-W4R 4 WIRE RESISTIVE TOUCH SCREEN DISPLAY PANEL ORIGINAL EELY-ECW CO. LTD
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 spacers 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
