Understanding the 4-Wire Resistive Touch ScreenA 4-wire resistive touch screen consists of two flexible sheets coated with a resistive material. When you press the screen, the two layers make contact, creating a voltage divider that can be measured. The four wires correspond to the two layers of the

Understanding the 4-Wire Resistive Touch ScreenA 4-wire resistive touch screen consists of two flexible layers separated by a thin gap. When pressure is applied to the screen, the two layers make contact, allowing the system to detect the touch location. The four wires correspond to the two layers o
