摘要： 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.

摘要： An in-cell multi-touch display panel system includes a touch LCD panel and a touch display control subsystem. The touch LCD panel has a TFT layer, a conductive electrode layer, and a common-voltage and touch-driving layer. The TFT layer has K gate driving lines and L source driving lines for a display operation. The conductive electrode layer has M first conduct lines for a touch detection operation by sampling a touch detection result from the M first conduct lines. The common-voltage and touch-driving layer has N second conduct lines for receiving a common voltage signal in display and receiving a touch-driving signal in touch detection. The K gate driving lines are divided into N groups respectively corresponding to the N second conduct line. When one group of gate driving lines has the display driving signal, the corresponding second conduct line is connected to the common voltage signal.
