1. A driving method for a touch panel comprising:
controlling the touch panel to scan and display at least one first image frame according to a first timing sequence, wherein the first timing sequence comprises a plurality of first display stages and a plurality of first touch stages alternately performed in time-sharing, the touch panel is configured to scan and display the first image frame in the first display stages and load touch signals in the first touch stages, and a first switching position is defined between each of the first display stages and each of the first touch stages;
determining a second timing sequence according to the first timing sequence, wherein the second timing sequence comprises a plurality of second display stages and a plurality of second touch stages alternately performed in time-sharing, a second switching position is defined between each of the second display stages and each of the second touch stages, and the second switching position is different from the first switching position; and
controlling the touch panel to scan and display at least one second image frame according to the second timing sequence, wherein the second image frame is located after the first image frame, and the touch panel is further configured to scan and display the second image frame in the second display stages and load touch signals in the second touch stages,
wherein a first one of the first display stages in the first timing sequence has a first duration, and a first one of the second display stages in the second timing sequence has a second duration; each of the first touch stages has a third duration, and one of the first display stages between any adjacent two of the first touch stages has a fourth duration; and each of the second touch stages has a fifth duration, and one of the second display stages between any adjacent two of the second touch stages has a sixth duration; and
wherein the second duration is not equal to the first duration, the third duration is equal to the fifth duration, and the fourth duration is equal to the sixth duration.
