Rezistive touch panel

4-Wire

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..

5-Wire

5-Wire resistive touch screen is the preferred solution for applications requiring durability and reliability over time. Similar to the 4-Wire technology, 5-Wire touch screen also consists of a conductive bottom layer (ITO Glass or ITO Film) and a conductive top layer (ITO Film).
The fundamental structure difference between the two is: in the 5-wire technology, all the electrodes are placed on the bottom layer and the top layer acts only as a voltage measuring probe. Therefore, the touch screen works properly even with damages or scratches on the top layer.
