Abstract:
1. A driving method for a touch panel having a plurality of electrodes, wherein the electrodes are coupled to a driving circuit respectively via different electrical paths, the driving method for the touch panel comprises: 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, wherein the driving configuration comprises corresponding relations of a first electrode, a second electrode and a third electrode among the electrodes which are respectively corresponding to a first operational configuration, a second operational configuration and a third operational configuration; providing a driving signal from the driving circuit to the electrodes having the first operational configuration during one of the sub-frame periods; reading sub-frame sensing values by the driving circuit from the electrodes having the second operational configuration during the same one of the sub-frame periods; and providing a shield potential from the driving circuit to the electrodes having the third operational configuration during the same one of the sub-frame periods; and integrating the sub-frame sensing values respectively obtained during the sub-frame periods by the driving circuit for obtaining a touch information of the touch panel during the first frame period.
