Abstract: An electronic circuit, adapted to drive a display panel comprising touch sensors, is provided. The electronic circuit can include a display driving circuit, a timing circuit and a touch scan circuit. The display driving circuit drives a touch display panel. The timing circuit receives a flag signal from a processing circuit and generates a scan start signal according to the flag signal. The touch scan circuit generates a plurality of touch scan signals according to the scan start signal and a touch column synchronization signal. The touch scan circuit determines a start time of a touch frame period according to a pulse of the scan start signal. The scan start signal can be asynchronous or delayed with respect to a touch frame synchronization signal generated by the display driving circuit.
