Abstract

The present disclosure provides a display panel and a display device. The display panel includes: a base substrate including a display area and a non-display area, the non-display area including: a lead area, a bending area, and a bonding area; a plurality of touch wirings arranged on the base substrate, one end of the touch wirings being connected to the display area, and the other end extending to the bonding area via the lead area and the bending area; signal wirings including a first portion located at the lead area, a second portion located at the bending area, and a third portion located at the bonding area, the second portion including a plurality of sub-signal wirings, the plurality of sub-signal wirings being divided into a plurality of sub-signal wiring groups; where in the bending area, the touch wirings and the sub-signal wiring groups are alternately distributed in a first direction.

First claim

What is claimed is:

1 . A display panel, comprising:
a base substrate comprising a display area and a non-display area located at the periphery of the display area, the non-display area comprising: a lead area, a bending area, and a bonding area; a plurality of touch wirings arranged on the base substrate, one end of the touch wirings being connected to the display area, and the other end extending to the bonding area via the lead area and the bending area; signal wirings comprising a first portion located at the lead area, a second portion located at the bending area, and a third portion located at the bonding area, the second portion comprising a plurality of sub-signal wirings, the plurality of sub-signal wirings being divided into a plurality of sub-signal wiring groups, and the sub-signal wiring groups comprising at least one of the sub-signal wirings; wherein in the bending area, the touch wirings and the sub-signal wiring groups are alternately distributed in a first direction, and the first direction intersects with an extension direction of the touch wirings and the sub-signal wirings in the bonding area.

2 . The display panel according to claim 1 , wherein a portion of the touch wirings in the bending area and a second portion of the signal wirings are made of a single layer of metal.

3 . The display panel according to claim 2 , wherein the portion of the touch wirings in the bending area and the second portion of the signal wirings are arranged in the same layer and the same material.

4 . The display panel according to claim 3 , wherein the portion of the touch wirings in the bending area and the second portion of the signal wirings are arranged in the same layer and the same material as a source-drain metal layer or a gate metal layer of the display panel.

5 . The display panel according to claim 1 , wherein in the lead area and/or the bonding area, the touch wirings and the signal wirings are arranged in different layers, and the touch wirings are located on one side of the signal wirings away from the base substrate.

6 . The display panel according to claim 5 , wherein in the lead area and/or the bonding area, the signal wirings are arranged in the same layer and the same material as the source-drain metal layer of the display panel.

7 . The display panel according to claim 1 , wherein in the lead area and/or the bonding area, the signal wirings are arranged in a plate shape, and the orthographic projection of the touch wirings on the base substrate is at least partially located in the orthographic projection area of the signal wirings on the base substrate.

8 . The display panel according to claim 1 , wherein in the bending area, each of the touch wirings occupies one pitch, and each of the sub-signal wiring groups occupies two pitches.

9 . The display panel according to claim 1 , wherein the touch wirings comprise touch driving wirings and touch sensing wirings.

10 . The display panel according to claim 1 , wherein the signal wirings are VSS signal lines.

11 . The display panel according to claim 1 , wherein the first direction is perpendicular to the extension direction of the touch wirings and the sub-signal wirings in the bonding area.

12 . A display device, comprising the display panel according to claim 1 .

13 . The display device according to claim 12 , wherein a portion of the touch wirings in the bending area and a second portion of the signal wirings are made of a single layer of metal.

14 . The display device according to claim 13 , wherein the portion of the touch wirings in the bending area and the second portion of the signal wirings are arranged in the same layer and the same material.

15 . The display device according to claim 14 , wherein the portion of the touch wirings in the bending area and the second portion of the signal wirings are arranged in the same layer and the same material as a source-drain metal layer or a gate metal layer of the display panel.

16 . The display device according to claim 12 , wherein in the lead area and/or the bonding area, the touch wirings and the signal wirings are arranged in different layers, and the touch wirings are located on one side of the signal wirings away from the base substrate.

17 . The display device according to claim 16 , wherein in the lead area and/or the bonding area, the signal wirings are arranged in the same layer and the same material as the source-drain metal layer of the display panel.

18 . The display device according to claim 12 , wherein in the lead area and/or the bonding area, the signal wirings are arranged in a plate shape, and the orthographic projection of the touch wirings on the base substrate is at least partially located in the orthographic projection area of the signal wirings on the base substrate.

19 . The display device according to claim 12 , wherein in the bending area, each of the touch wirings occupies one pitch, and each of the sub-signal wiring groups occupies two pitches.

20 . The display device according to claim 12 , wherein the touch wirings comprise touch driving wirings and touch sensing wirings.
