1. A driver circuit, configured to drive a touch display panel, the driver circuit comprising:
a timing control circuit, configured to output a touch driving signal to a sensor, wherein the sensor generates a sensing signal according to the touch driving signal;
a touch sensing circuit, coupled to the timing control circuit and configured to receive the sensing signal; and
a display driver circuit, coupled to the timing control circuit and configured to output a prohibit duration signal to the timing control circuit,
wherein the timing control circuit determines a timing of the touch driving signal according to the prohibit duration signal to drive the sensor to generate the sensing signal.
