Claim:
1. A touch display panel, comprising: an upper substrate and a lower substrate which are arranged oppositely; a liquid crystal layer between the upper substrate and the lower substrate; a pixel electrode and a common electrode layer which are insulated from each other; and a plurality of wires; wherein the common electrode layer is divided into a plurality of self capacitance electrodes, and each self capacitance electrode is connected to one of the plurality of wires; a compensating electrode arranged in a layer different from that of the self capacitance electrodes and insulated from the self capacitance electrodes; wherein the compensating electrode at least covers a portion of a partition gap between neighboring self capacitance electrodes; wherein a common electrode signal is applied to the compensating electrode during a display period; and wherein the self capacitance electrodes, the wires, and the compensating electrode are arranged on a surface of one of the upper substrate and the lower substrate so that the self capacitance electrodes, the wires, and the compensating electrode face the other of the upper substrate and the lower substrate.
