IN-CELL TOUCH PANEL AND DISPLAY DEVICE

摘要

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.

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 side, 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; and an insulation layer that is provided between the self-capacitance electrodes and the wires; wherein the insulation layer, in an area that each self-capacitance electrodes overlaps a corresponding wire, is provided with at least a first hole that runs through the insulation layer and each self-capacitance electrode is electrically connected with the 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, and the second via hole runs through the self-capacitance electrode, and an orthogonal projection of the second via hole on the lower substrate covers an orthogonal projection of the first via hole on the lower substrate.
