Product Description:

4-Wire Resistive touch screen 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 Resitive touchscreen is an outstanding high quality product, suitable for low cost solution. It is inherently of many advantages such as high accuracy, quick response, drift-free, stable and long durability for a life time of 1,000,000 times finger touches. Kingtouch Technology’s 4 wire Resistive touchscreen featured contamination-resistant and waterproof, is designed for the harshest environment such as dust is prevalent or liquid spills, splashes and wash down. It can be touched by finger, gloved finger, leather or stylus pen.
