FG4_6.5-0001 is a 6.5 inch diagonal 4-wire Resistive Touch Screen. Active Area Dimension is 132.5mm x 99.4mm. The 4-wire Resistive Touch Screen is the preferred solution for low-cost applications. It consists of a conductive bottom layer of either glass or film and a conductive top film layer, separated by extremely small, transparent spacer dots. A voltage is applied across the conductive surface. When pressure from a touch is applied to the top layer, it is deflected and makes contact with the bottom layer resulting in a voltage drop. This change is detected by the controller. By alternating the voltage signal between the top layer and the bottom layer, the X and Y coordinates of the user’s touch are computed.
