Claim:
1. An in-cell touch panel comprising: a first substrate and a second substrate disposed oppositely to each other, a common electrode layer comprising a plurality of strip-like slits disposed on a side of the second substrate, which side faces the first substrate, and a touch sensing chip; wherein the common electrode layer comprises a plurality of mutually independent self-capacitance electrodes distributed along the strip-like slits and a direction crossing the strip-like slits; and the touch sensing chip is configured to apply common electrode signals to the self-capacitance electrodes in a display time period and determine touch positions by detecting capacitance value variation of self-capacitance electrodes in a touch time period; further comprising: a black matrix layer disposed on a side of the first substrate, which side faces the second substrate, or on a side of the second substrate, which side faces the first substrate; and in the common electrode layer, orthogonal projections of partitioning gaps in the direction crossing the strip-like slits on the second substrate are all within regions in which a pattern of the black matrix layer is located; a plurality of wires connecting the self-capacitance electrodes to the touch sensing chip; wherein the wires and the self-capacitance electrodes are disposed on different layers; and pixel electrodes disposed between the second substrate and the common electrode layer; wherein a layer where the wires are located is disposed between the pixel electrodes and the common electrode layer or on a same layer as the pixel electrodes; wherein opposite sides of adjacent two of self-capacitance electrodes are both configured as bend lines.
