Operating Principle & Structure

四線原理

The 4-wire resistive touch panel is composed of two layers of conductive materials (Indium Tin Oxide, ITO), which are usually composed of conductive film (ITO film) and conductive glass (ITO glass), these two layers are divided by insulating Spacer Dots.

After the circuit passes through the upper and lower layers to contact each other, an analog voltage signal will be generated, which is the output of the circuit, converting into a digital signal by the controller, then the computer calculates the correct position of the touch. For 4-wire resistive touch panel, X-axis and Y-axis are made separately on the film and the glass, and separates the wiring in the action area. At the same time, a fixed voltage is set to become a uniform electric field, and the difference in voltage value will be converted into an accurate coordinate position.
