The touch panel 1071 can include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the touch position of the user and detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into contact coordinates, and then sends it to the processor 110, and can receive and execute commands sent by the processor 110.
