Overview
4-Wire resistive touch screen is the preferred solution for low cost applications. It consists of a conductive bottom layer (ITO Glass or Film) and a conductive top layer (ITO Film). The two layers are suspended by many very small spacer dots.
Product Details
Working Principle&Highlight：
4-Wire Resistive Touch Screens 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 ITO 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. Highly Reliable, Economical and Efficient,Multitude Application Input flexibility –finger (with/without glove), stylus, pen, credit card.
