摘要:
A driving method for a touch panel is provided. The touch panel has a plurality of electrodes, the plurality of electrodes are coupled to a driving circuit respectively via different electrical paths. The driving method includes: defining a plurality of sub-frame periods in a first frame period; converting a driving configuration for providing the driving configuration that is different from each other respectively to each of the sub-frame periods; the driving circuit drives the electrodes respectively with the driving configuration corresponding to one of the sub-frame periods during the sub-frame periods for obtaining at least one of the sub-frame sensing values from each of the sub-frame periods; and the driving circuit integrates the sub-frame sensing values respectively obtained during the sub-frame periods for obtaining a touch information of the touch panel during the first frame period.
