Abstract: A driving method for charger noise rejection in a touch panel has steps of: reading the sensing frame of the touch panel with a self-capacitance sensing mode, marking at least one first-axis sensing line having a recognizable sensing value, and driving the at least one marked first-axis sensing line with a mutual-capacitance sensing mode to acquire at least one sensing value corresponding to at least one sensing point on each one of the at least one marked first-axis sensing line. Accordingly, the charger noise is rejected in the touch panel by the driving method of the present invention.

Abstract: A scan method for a capacitive touch panel has steps of performing a relatively small first number of estimation scans on multiple sensing lines of a capacitive touch panel and recording results of the estimation scans, marking the sensing lines meeting a predetermined condition according to the results of the estimation scans, and performing a relatively large second number of practical scans on the marked sensing lines. Given the first-stage estimation scans and the second-stage practical scans, the sensing lines possibly touched by a touch object can be rapidly identified and marked, and the second-stage practical scans are performed on the marked sensing lines. Accordingly, noises and errors can be effectively reduced, accurate scan can be ensured, and higher frame rate can be achieved.

Further, the present invention also increases the frame rate since only a part of sensing lines need to be scanned.
