1. A driving method for reducing display interference in an in-cell multi-touch panel having a thin film transistor (TFT) layer, a sensing electrode layer, and a common voltage and touch driving layer, wherein the TFT layer having K gate lines and L source lines, the sensing electrode layer having M sensing lines, the common voltage and touch driving layer having N touch driving lines, where K, L, N, M are positive integers respectively, the driving method comprising:

  • providing a display driving signal to the K gate lines and a display pixel signal to the L source lines so as to drive corresponding transistors and capacitors in a display frame for displaying an image; and

    providing a touch driving signal to the N touch driving lines and receiving touch signals from the M sensing lines so as to detect touch point positions of an external object in a touch frame,wherein the touch frame and the display frame are synchronous and have the same time width and, sequence of providing the touch driving signal to the N touch driving lines are different for the touch frames respectively.
