The resistive touch screen converts the physical position of the touch point (X, Y) in the rectangular area into a voltage representing the X coordinate and the Y coordinate. This screen can use four, five, seven or eight lines to generate the screen bias voltage while reading back the voltage at the touch point. Resistive touch screen is mainly divided into four-wire touch screen, five-wire touch screen, seven-line touch and eight-line touch screen.

A capacitive touch screen is a layer of transparent special metal conductive material attached to the surface of the glass. When the finger touches the metal layer, the capacitance of the contact changes, so that the frequency of the oscillator connected to it changes, and the position of the touch can be determined by measuring the frequency change.
