Abstract
In a driving method for reducing display interference in in-cell multi-touch panel, a display driving signal is provided to K gate lines and a display image signal is provided to L source lines so as to drive corresponding transistors and capacitors in a display frame for displaying an image. The method also provides a touch driving signal to N touch driving lines and receives touch signals from M sensing lines to thereby detect one or more touch point positions of an external object in a touch frame based on the touch driving signal. In each touch frame, a sequence of providing the touch driving signal to N touch driving lines is different.
