摘要： An in-cell touch panel and a display device are provided. Self-capacitance electrodes arranged in the same layer as pixel electrodes are disposed at gaps between the pixel electrodes of the touch panel in accordance with the self-capacitance principle. A touch detection chip can determine a touch position by detection of capacitance variation of the self-capacitance electrodes in a touch period. The touch panel does not need to add additional processes on the basis of the manufacturing process of an array substrate and hence can reduce the manufacturing cost and improve the productivity.

摘要： An in-cell touch panel and a display device are disclosed. A plurality of mutually independent self-capacitance electrodes arranged in the same layer are disposed in the touch panel in accordance with the self-capacitance principle. A touch detection chip can determine the touch position by the detection of the capacitance variation of the self-capacitance electrode. Compared with the case that body capacitance only acts on the projected capacitance in mutual capacitance, the in-cell touch panel can effectively improve the signal-to-noise ratio of touch and hence can improve the accuracy of touch sensing.
