 4-Wire Resistive Touch Screen Description:
|
  
4-Wire Resistive Touch Screens are generally built with two layers of electrically conductive materials (ITO Indium Tin Oxide or ATO Antimony Tin Oxide) separated by insulated dots. When an object touches the device, the two layers come into contact. The contact produces a change in electrical current and is registered as an analog touch event signal. The signal is then sent through the circuit to be converted into a digital signal by the controller for the device to compute the exact location of the touch event.
4-Wire Resistive Touch technology is suitable for applications that require ease of integration, low power consumption, lightweight, portability, cost effectiveness and compact mechanism. Affordable, durable and versatile, the 4-wire resistive touch screens are primarily used in mobile applications, such as smart phones, PDAs, e-books, web pads, digital cameras, GPS, and other consumer or office electronics.
