The second electrode 5 may also be referred to as a touch sensing electrode (hereinafter, the second electrode is referred to as a touch sensing electrode) for sensing a touch operation. Coupling capacitance is formed between the touch scanning electrode 4 and the touch sensing electrode 5, or the touch scanning electrode 4 and the touch sensing electrode 5 respectively form capacitance with the ground, when a finger touches the display panel, the capacitance of the finger will be superposed on the capacitance formed by the touch scanning electrode 4 and the touch sensing electrode 5 corresponding to the touch point, and the position of the touch point can be determined by detecting the change of capacitance of each position on the display panel.
