Abstract:
1. A capacitive in-cell touch panel comprising: a color filter substrate, a thin film transistor TFT array substrate having a common electrode layer, and a liquid crystal layer between the color filter substrate and the TFT array substrate, wherein a plurality of pixel units arranged in a matrix are set in the capacitive in-cell touch panel; two gate signal lines are arranged between two adjacent rows of pixel units on the TFT array substrate, and two adjacent columns of pixel units constitute a group and commonly use a same data signal line located between the two adjacent columns of pixel units, wherein, the color filter substrate has a plurality of touch sensing electrodes; the common electrode layer of the TFT array substrate has a plurality of touch driving electrodes, each of which is electrically connected to at least one touch driving signal line located between two adjacent groups of columns of pixel units; during a display period of a frame of picture, each of the touch driving signal lines electrically connected to the touch driving electrode is used to transmit a common electrode signal and a touch scanning signal to the touch driving electrode in a time division manner; wherein each of the touch driving electrodes has concave structures in areas overlapping with the touch sensing electrode; the common electrode layer of the TFT array substrate further has a plurality of common electrodes, and each of the common electrodes is located within the concave structures between the adjacent touch driving electrodes and is isolated from the touch driving electrodes.
