4 wire resistive touch screen
4-wire touch screens are suitable for small or medium sized products such as HMI and hand-held systems. These panels utilize X+, X-, Y+ and Y- lead outs at the four edges of the screen. When contact is made, X/Y read-outs are then read by the controller and converted into the correct coordinates.
