Working Principle

The CP8387ATT controller works by detecting changes in the internal electric field that occurs when a finger is near the touch panel. When a finger touches the touch panel, the electric field surrounding it changes and the controller can detect this change. The controller then converts this signal into a digital signal, which can be used by the host processor for the required application.

The controller can measure the pressure applied on the surface of the touch panel and can distinguish between a real finger touch and a false one. This helps to eliminate faulty inputs caused by objects like a pen, pencil, or a stylus. The controller is also capable of filtering out accidental touches and rejecting ghost touches.
