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 above the substrate, a first conductive layer and a second conductive layer being integrated in the thin-film transistor layer, wherein the first conductive layer, a source electrode, and a drain electrode are formed simultaneously, and the second conductive layer is connected with a transparent conductive layer coupled to a common voltage;

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

    a color filtering layer, disposed above the liquid crystal layer; and

    a glass layer, disposed above the color filtering layer;

    wherein the first conductive layer and the second conductive layer are used as bridges of a transmitter electrode and a multi-function electrode above an active area of the in-cell mutual-capacitive touch panel;

    the second conductive layer and the transparent conductive layer are used as bridges of the transmitter electrode and the multi-function electrode at the lower-side out of the active area of the in-cell mutual-capacitive touch panel;

    the in-cell mutual-capacitive touch panel is cooperated with at least one driving IC having more than two sets of transmitter electrode pins and multi-function electrode pins;

    the number of the at least one driving IC is determined according to a size of the in-cell mutual-capacitive touch panel, and the at least one driving IC is disposed out of the active area of the in-cell mutual-capacitive touch panel.
