In-cell capacitive touch panel lcd module and method for driving the same

A method for driving an in-cell capacitive touch panel LCD module, wherein the in-cell capacitive touch panel LCD module comprises:

• a first substrate and a second substrate disposed opposite to each other;
• a plurality of spaced driving lines and a plurality of spaced sensing lines disposed between the first substrate and the second substrate, wherein the driving lines cross the sensing lines;
• a common electrode layer disposed between the first substrate and the second substrate and located below the driving lines and the sensing lines,
• the common electrode layer comprises a plurality of spaced first common electrodes and a plurality of spaced second common electrodes;
• at least part of the driving line overlaps with the first common electrode, and at least part of the sensing line overlaps with the second common electrode;
• the first common electrode is disposed at an interval between two adjacent second common electrodes;
• and
• the first common electrodes cross the second common electrodes and the first common electrodes are electrically isolated from the second common electrodes;
• and
• a control circuit,
• the method comprising:
• dividing, by the control circuit, a time period of each frame into a display time period and a touch control time period;
• supplying, by the control circuit, a display signal to the common electrode layer during the display time period;
• and
• supplying, by the control circuit, a first touch control signal to the first common electrode and a second touch control signal to the second common electrode during the touch time period, wherein the first touch control signal causes the first common electrode to have an electric potential equal to an electric potential of the driving line, and wherein the second touch control signal causes the second common electrode to have an electric potential equal to an electric potential of the sensing line.
