1. An in-cell mutual-capacitive touch panel, comprising:

  • a plurality of pixels, a laminated structure of each pixel comprising;

    a substrate;

    a thin-film transistor layer disposed on the substrate, wherein a first conductive layer and a common electrode are disposed in the TFT layer, and the first conductive layer is arranged in mesh type or only arranged along a first direction in an active area of the in-cell mutual-capacitive touch panel;

    a liquid crystal layer disposed above the thin-film transistor layer;

    a color filter layer disposed above the liquid crystal layer; and

    a glass layer disposed above the color filter layer;

    wherein touch electrodes of the in-cell mutual-capacitive touch panel comprises a first direction electrode and a second direction electrode, the first direction electrode is formed by the first conductive layer arranged in mesh type and the second direction electrode is formed by the first conductive layer arranged along the first direction in the active area electrically connected with the common electrode through a via;

    wherein a multi-function electrode is disposed between the first direction electrode and the second direction electrode;

    the multi-function electrode is formed by the first conductive layer arranged along the first direction in the active area electrically connected with the common electrode through a via.
