12inch 4wire touch screen supply best price original high quality

The four-wire resistive touch screen is the most widely used resistance family, the most popular one. Its structure consists of a conductive ITO layer of the next line (glass or film material) conductive ITO layer and the line (film material). The middle of a minor insulation separated by a dot, when the touch screen surface without pressure, up and down the line into the open state. Once the pressure is applied to the touch screen, up and down the line conduction, the controller through the next line of conductive ITO layer on the X-coordinate direction to impose driving voltage through the conductive ITO layer on the line on the probe to detect the voltage on the X direction by this projection X coordinate of the contact. By the controller to change the direction of the applied voltage, empathy can be measured by the Y coordinate of the contact to clarify the location of the contacts.
