A 4 Wire Touch Screen typically consists of an ITO‑coated glass substrate and an ITO‑coated film separated by micro‑spacers that prevent accidental contact. When a user presses the film, the two conductive layers make contact and create an analog voltage signal corresponding to the touch position.[6][7][1]
- Along one axis, a fixed voltage is applied between two electrodes on one conductive layer so the surface becomes a uniform electric field, while the other axis is measured by the controller.[2][6]
- By switching the voltage orientation between the two layers, the controller can measure both X and Y coordinates, providing precise single‑touch detection for the 4 Wire Touch Screen.[7][6]
- Typical performance indicators include transparency around 80 percent, surface hardness of about 3H, operating force below roughly 80 g, linearity better than 1.5 percent, and durability up to about 1 million stylus actuations.[9][6]
The analog signals from a 4 Wire Touch Screen are processed by a dedicated touch controller that filters noise, calculates coordinates, and communicates with the host system via interfaces such as I⊃2;C, SPI, or USB.
