1. An in-cell touch panel, comprising:

  • a first substrate and a second substrate arranged opposite to each other, a common electrode layer disposed on one side of the first substrate facing the second substrate, and a touch detection chip, whereinthe common electrode layer includes a plurality of mutually independent self-capacitance electrodes and a plurality of leads configured to connect the self-capacitance electrodes to the touch detection chip; and

    the touch detection chip is configured to apply common electrode signals to the self-capacitance electrodes in a display period and determine the touch position by the detection of the capacitance variation of the self-capacitance electrode in a touch period.
