4 wire Resistive touch screen works:   

        GreenTouch 4 wire resistive touch screen consists of two parts:1. ITO glass substrate (ITO Glass): plated by a piece of glass or plexiglass as the substrate, the surface of a transparent conductive layer.2. ITO polyester plastic layer (ITO Film): surface-hardened, the surface is smooth and has a scratch-resistant features, its inner surface coated with a transparent conductive layer, tightly bonded to the surface of the ITO glass substrate.

     When a voltage is applied when the electrode layer will form a voltage gradient on the network. If an external force makes contact with upper and lower layers at a certain point, then another layer of electrodes no voltage is applied voltage that can be measured at the point of contact, so you know the coordinates of the contact point. For example, the voltage, the voltage gradient is formed on the top conductor layer coupled to the electrode (X +, X-) at the top, when an external force makes contact with upper and lower layers at some point, at the bottom you can measure the voltage at the point of contact , according to between (X +) the voltage of the electrode distance relationship, know where the X coordinate. Then, the voltage is switched to the bottom electrode (Y +, Y-) on, and measure the voltage at the point of contact at the top, so know Y coordinates.
