Abstract
An embedded touch screen display panel driving mechanism includes a number of common electrodes, a number of pixel units each including a pixel electrode, and a number of touch sensing electrodes. The common electrodes can receive a first common voltage to cooperatively induce a first electric field with the pixel electrodes to drive liquid crystals of a liquid crystal layer to rotate to display according to data signals received by the pixel electrodes. The common electrodes can also receive a second common voltage to cooperatively induce a second electric field with the touch sensing electrodes to enable the touch sensing electrodes to transmit touch signals corresponding to touch input on the touch electrodes. At any one time, some common electrodes receive the first common voltage while other common electrodes receive the second common voltage.
