- an in-cell touch panel and a display device provided by the embodiments of the present invention, since the self-capacitance electrode has a plurality of hollow regions, the area of the respective capacitor electrodes can be reduced, thereby reducing the inherent capacitance of the respective capacitor electrodes; If the finger capacitance is constant, the capacitance on the self-capacitance electrode is solid. The capacitance plus the finger capacitance is relatively small, thereby reducing the RC delay of the feedback signal on the self-capacitance electrode; and, since the amount of capacitance change on the self-capacitance electrode before and after the touch is relatively increased relative to its inherent capacitance, the opposite finger The amount of change in the feedback signal caused will increase, thereby increasing the touch sensitivity of the touch screen.
- the touch sensitivity of the touch screen can be increased on the basis of ensuring the design of the narrow bezel.
