1. A capacitive in-cell touch panel, comprising:

  • a color filter substrate, a thin-film transistor (TFT) array substrate and a liquid crystal layer disposed between the color filter substrate and the TFT array substrate, whereinthe capacitive in-cell touch panel is formed with a plurality of pixel units arranged in a matrix;

    two gate signal lines are disposed between every two adjacent rows of pixel units in the TFT array substrate, every two adjacent columns of pixel units being are taken as a group of pixel unit columns, and a data signal line is disposed between the two pixel unit columns in each group of pixel unit columns and shared by the two pixel unit columns;

    the TFT array substrate includes a plurality of touch driving electrodes disposed at gaps between adjacent groups of pixel unit columns; and

    the color filter substrate includes a plurality of touch sensing electrodes extended along a row direction of the pixel units.
