1. a kind of In-cell touch panel, including the upper substrate and lower substrate being oppositely arranged, arranged in arrays is multiple mutually indepedentAnd the self-capacitance electrode of same layer setting, in the touch-control period by detecting the capacitance variation of each self-capacitance electrode to judgeThe touch detection chip of position of touch, and the self-capacitance electrode is connected to a plurality of conducting wire of the touch detection chip,It is characterized by:

  • The conducting wire and the self-capacitance electrode are all set in the upper substrate towards the lower substrate side or the lower substrateTowards the upper substrate side;

    Each self-capacitance electrode all has multiple hollowed out areas;

    The self-capacitance electrode is located at the lower substrate towards the upper substrate side;

    The In-cell touch panel further include;

    withThe self-capacitance electrode same layer setting, the public electrode in each hollowed out area of the self-capacitance electrode, and it is described publicMutually insulated between electrode and the self-capacitance electrode;

    The touch detection chip is also used in the display period to each public affairsCommon electrode loads common electrode signal.
