In-cell touch panel and display device
First Claim
1. An in-cell touch screen, comprising:
- an upper substrate and a lower substrate that are provided opposite to each other;
a plurality of mutually independent self-capacitance electrodes disposed on a side, facing the lower substrate, of the upper substrate, or disposed on aside, facing the upper substrate, of the lower substrate;
wires that are disposed on a different layer from the self-capacitance electrodes and electrically connected correspondingly with the self-capacitance electrodes in a one-to-one manner; and
an insulation layer that is provided between the self-capacitance electrodes and the wires;
wherein the mutually independent self-capacitance electrodes comprise at least one first self-capacitance electrode that overlaps at least two of the wires, and the at least two of the wires comprise a first wire that is connected with the first self-capacitance electrode and at least one second wire that is not connected with the first self-capacitance electrode;
the insulation layer, in an area where the first self-capacitance electrode overlaps each of the at least two wires, is provided with at least one first via hole running through the insulation layer, and the first self-capacitance electrode is electrically connected with the first wire through the at least one first via hole overlapping the first wire;
the first self-capacitance electrode is provided with a second via hole which overlaps each of the at least one second wire, and the at least one second via hole runs through the first self-capacitance electrode, and an orthogonal projection of the second via hole on the lower substrate covers an orthogonal projection of the at least one first via holes overlapping each of the at least one second wire.

Abstract
An in-cell touch screen and a display device are provided. In the in-cell touch screens, an insulation layer, in an area that each self-capacitance electrode overlap a wire, is provided with at least a first hole that runs through the insulation layer and each self-capacitance electrode is electrically connected with a corresponding wire via a corresponding first via hole; each self-capacitance electrode, within an area overlapping other wire than the corresponding wire and at a position corresponding to the first via hole, is disposed with a second via hole that runs through the self-capacitance electrode. An orthogonal projection of a second via hole on a lower substrate covers an orthogonal projection of a first via hole on the lower substrate. The in-cell touch screen can solve a problem of uneven image display due to nonuniform distribution of via holes in an insulation layer.
