Resistive touch screen
Overview:
Resistive touch screen from the next line (glass or film material) conductive ITO layer and the line (film material) conductive ITO layer. Use subtle insulating intermediate point separated when the touch screen surface without pressure, the bottom line into the open. Once the pressure applied to the touch screen, the vertical line is turned on, the controller through the lower conductive ITO layer line drive voltage is applied in the X coordinate direction, through conductive ITO layer on the line probe on the voltage detected in the X direction,, thus calculate the X coordinate of the contact. Through the controller to change the direction of the applied voltage, empathy can be measured contacts the Y coordinate, so as to clarify the position of contacts.
