Abstract: A touch scanning method shortening a first touch latency includes: scanning a Mth column of the N-column touch panel according to a touch scan (TSHD) signal; determining whether the finger is on the Mth column of the N-column touch panel according to a scan data signal; performing a fast done process according to a fast done signal when the finger is on the Mth column of the N-column touch panel; determining whether M equals to N when the finger is not on the Mth column of the N-column touch panel; and resetting M to 1 according to a scan start signal and performing an algorithm according to a finish flag signal.

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.
