Abstract: An in-cell touch panel LCD module (100) and a method for driving the same includes a common electrode layer including first and second common electrodes. A control circuit divides the frame time period into a display time period and a touch control time period. A display signal is applied to the common electrode layer during the display time period for a normal LCD display. First and second touch control signals are applied to the first and second common electrodes, respectively, during the touch control time period, so that the electric potential of the first common electrode equals to that of the driving line and the electric potential of the second common electrode equals to that of the sensing line.
