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.
