Product Name: Touch screen
Place of Origin: China

Specifications:

Available size: 2.8" ~ 21" ( standard and custom)

Description: 4 Wire Touch Screen

Touch screen has two-layer structure, i. E. The top layer, ITO film and the bottom layer, ITO glass or film. They are use PET film and glass as substrate material respectively, and then the ITO (Indium Tin Oxide) is coated on the film and glass surface. The non-conductive surface of the film is treated with hard coating to prevent scratch. The ITO film and ITO glass are separated by printed very small transparent insulation spacers (<1/1000 inch). When operating, each conductive layer is given uniformly a voltage by controller: Usually X direction is on the ITO film, Y direction on the ITO glass or film. When screen is touched, both conductive layers of the top film and bottom glass make an electrical contact. The controller will get the X and Y coordination by calculating the voltage of the touching point.
