Abstract: A driver circuit, configured to drive a touch display panel, is provided. The touch display panel includes a sensor. The driver circuit includes a timing control circuit and a touch sensing circuit. The timing control circuit is configured to output a touch driving signal to the sensor. The sensor generates a sensing signal according to the touch driving signal. The touch sensing circuit is coupled to the timing control circuit and is configured to receive the sensing signal. The timing control circuit determines a timing of the touch driving signal according to a noise duration signal to drive the sensor to generate the sensing signal.

Abstract: A driver circuit, configured to drive a touch display panel, is provided. The touch display panel includes a sensor. The driver circuit includes a timing control circuit and a touch sensing circuit. The timing control circuit is configured to output a touch driving signal to the sensor. The sensor generates a sensing signal according to the touch driving signal. The touch sensing circuit is coupled to the timing control circuit and is configured to receive the sensing signal. The timing control circuit determines a timing of the touch driving signal according to a noise duration signal to drive the sensor to generate the sensing signal.
