84 touch screen displays.The five-wire touch screen uses a resistive layer and a conductive layer. The conductive layer has a contact, usually on the edge of one side. Each of the four corners of the resistive layer has a contact. To measure in the X- axis direction, the upper left and lower left corners are offset to VREF , and the upper right and lower right corners are grounded. Because the left and right corners are the same voltage, the effect is similar to connecting the bus on the left and right, similar to the method used in a four-wire touch screen.
