Kingtouch Technology is specialized in producing surface acoustic wave(SAW) touch screen, Multi-touch Infrared touch screen/ IR Touch Frame, Interactive touch foil, resistive touch screen, LCD touch PC/ Computer / Touch Tablet PC, Optical touch screen and Capacitive touch screen, Any size of touch panel we can customized for you. Just let us know the requirement.
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.
Advantage:
--Low cost solution, Low power consumption
--To be activated with any device
--Finger, gloved hand and stylus activation
--High accuracy and sensitivity
--High durability and reliability
--Contaminant proof and liquid resistance.
Application
--Light industrial
--Home appliances
--Portable sport devices
--Access control terminals
--Portable medical devices
--Personal computer and office.
