Abstract

A display panel and a display device are provided in embodiments of the disclosure, including: a first substrate, on a display side; and a second substrate opposite to the first substrate; and a first transparent conductive pattern is provided on a side of the first substrate facing towards the second substrate, and is arranged to be electrically connected to a ground point.

First claim

What is claimed is:

1 . A display panel, comprising:
a first substrate, on a display side; and a second substrate opposite to the first substrate, wherein a first transparent conductive pattern is provided on a side of the first substrate facing towards the second substrate, and is arranged to be electrically connected to a ground point.

2 . The display panel according to claim 1 , wherein an orthogonal projection of the first transparent conductive pattern on the second substrate at least partially covers a display region of the second substrate.

3 . The display panel according to claim 2 , wherein a second transparent conductive pattern is provided on a side of the second substrate facing towards the first substrate, and is arranged to be electrically connected to the ground point.

4 . The display panel according to claim 3 , wherein a combination of the orthogonal projection of the first transparent conductive pattern on the second substrate and an orthogonal projection of the second transparent conductive pattern on the second substrate completely covers the display region of the second substrate.

5 . The display panel according to claim 4 , wherein the orthogonal projection of the first transparent conductive pattern on the second substrate and the orthogonal projection of the second transparent conductive pattern on the second substrate are arranged to be staggered with each other.

6 . The display panel according to claim 5 , wherein the orthogonal projection of the first transparent conductive pattern on the second substrate and the orthogonal projection of the second transparent conductive pattern on the second substrate do not overlap with each other at all.

7 . The display panel according to claim 5 , wherein the orthogonal projection of the first transparent conductive pattern on the second substrate and the orthogonal projection of the second transparent conductive pattern on the second substrate at least partially overlap with each other.

8 . The display panel according to claim 3 , wherein a plurality of first touch electrodes are provided on a side of the first substrate facing towards the second substrate, and a plurality of second touch electrodes are provided on a side of the second substrate facing towards the first substrate.

9 . The display panel according to claim 8 , wherein the first transparent conductive pattern and the plurality of first touch electrodes are provided in one and the same layer, and the first transparent conductive pattern are located at gaps among adjacent ones of the plurality of first touch electrodes.

10 . The display panel according to claim 9 , wherein the first transparent conductive pattern fills the gaps among adjacent ones of the plurality of first touch electrodes.

11 . The display panel according to claim 8 , wherein the second transparent conductive pattern and the plurality of second touch electrodes are provided in one and the same layer, and the second transparent conductive pattern are located at gaps among adjacent ones of the plurality of second touch electrodes.

12 . The display panel according to claim 11 , wherein the second transparent conductive pattern fills the gaps among adjacent ones of the plurality of second touch electrodes.

13 . The display panel according to claim 8 , wherein the plurality of first touch electrodes are multiplexed as a plurality of first display electrodes, and the plurality of second touch electrodes are multiplexed as a plurality of second display electrodes.

14 . The display panel according to claim 13 , the plurality of first display electrodes belong to one type of a common electrode and pixel electrodes, and the plurality of second display electrodes belong to the other type of the common electrode and the pixel electrodes.

15 . A display device, comprising the display panel according to any one of claims 1 - 14 .

16 . The display device according to claim 15 , wherein the display device is an aviation display screen or a display screen for industrial-control equipment.
