Abstract:
A touch sensing circuit is provided. Signal generators output a pulse signal according to a control signal. Touch detection circuits are arranged as an array, generating a sensing signal according a touch event and the pulse signal. The touch detection circuits in the same row are coupled to the same signal generator. The sensing circuits are respectively coupled to the touch detection circuits in the same column, generating an output signal according to the sensing signal. The controller receives the output signal, outputs the control signal to control one of the signal generators outputting the pulse signal, and detects the touch detection circuit corresponding to the touch event according to the output control signal and the output signal.
