Working Principles

The TSC2301IGQZ operates based on capacitive touch sensing principles. When a conductive object, such as a finger, comes into contact with the touch screen, it causes a change in capacitance at specific sensing points. The controller measures these changes and converts them into digital signals that represent touch coordinates.

The touch screen is divided into X and Y axes, with each axis having two sensing inputs (X+ and X-, Y+ and Y-). By applying voltage to one axis and measuring the voltage on the other axis, the controller can determine the exact touch position.
