Resistive touch screen from the next line (glass or film material) conductive ITO layer and the line (film material) conductive ITO layer. Separated by using fine insulated middle, when the touch screen surface without pressure, the bottom line into the open. Once the pressure applied to the touch screen, turn-down line, the controller circuit through the conductive ITO layer under the X coordinate direction in the drive voltage is applied through conductive ITO layer on the line probe to detect the voltage on the X direction by The projected X coordinate of the contact. Through the controller to change the direction of the applied voltage, empathy can be measured contacts the Y coordinate, which clearly the position of contacts.
