Abstract

A display device includes: a display panel, a border pattern and a light shielding pattern. The display panel includes a display area and a non-display area surrounding the display area, the display panel further includes a plurality of signal lines in the display area and a plurality of signal leading lines in the non-display area, and the signal leading lines are electrically connected to the signal lines, respectively. The border pattern is located on a light-exit side of the display panel. The light shielding pattern is located on the light-exit side and on a side of the border pattern adjacent to the display panel. An orthographic projection of the light shielding pattern on the display panel is located within the non-display area, and the light shielding pattern is configured to block light reflected by the signal leading lines from exiting out from the light-exit side.

First claim

What is claimed is:

1. A display device, comprising:
a display panel comprising a display area and a non-display area surrounding the display area, the display panel further comprising a plurality of signal lines in the display area and a plurality of signal leading lines in the non-display area, and the plurality of signal leading lines being electrically connected to the plurality of signal lines, respectively;
a border pattern on a light-exit side of the display panel, an orthographic projection of the border pattern on the display panel being located within the non-display area; and
a light shielding pattern on the light-exit side of the display panel and on a side of the border pattern adjacent to the display panel,
wherein an orthographic projection of the light shielding pattern on the display panel is located within the non-display area, and the light shielding pattern is configured to block light reflected by the plurality of signal leading lines from exiting out from the light-exit side;
wherein various portions of the light shielding pattern have inconsistent light transmittances;
wherein an area in which the plurality of signal leading lines are located comprises a first leading line area and a second leading line area, and a light reflection capability of the first leading line area is higher than a light reflection capability of the second leading line area; and
wherein the light shielding pattern comprises a first pattern for blocking reflected light from the first leading line area and a second pattern for blocking reflected light from the second leading line area, and a light transmittance of the first pattern is lower than a light transmittance of the second pattern.

2. The display device of claim 1 , wherein the plurality of signal lines comprise a plurality of data lines, and the plurality of signal leading lines comprise a plurality of data leading lines.

3. The display device of claim 1 , wherein
the orthographic projection of the light shielding pattern on the display panel at least partially overlaps with the orthographic projection of the border pattern on the display panel.

4. The display device of claim 1 , wherein
at least a part of the orthographic projection of the light shielding pattern on the display panel is located within a middle area between the display area of the display panel and the orthographic projection of the border pattern on the display panel.

5. The display device of claim 1 , wherein the display device comprises a touch electrode layer on the light-exit side of the display panel, and the light shielding pattern is arranged on the touch electrode layer.

6. The display device of claim 1 , wherein the display device further comprises a layer structure on the light-exit side of the display panel, the light shielding pattern is connected to the layer structure, and the layer structure comprises at least one of a packaging layer, a polarizer, a touch electrode layer, or an optical adhesive layer.

7. The display device of claim 1 , wherein the display device further comprises a cover plate above the display panel, and the border pattern is formed on the cover plate.

8. The display device of claim 1 , wherein a distribution density of the signal leading lines in the first leading line area is greater than a distribution density of the signal leading lines in the second leading line area.

9. The display device of claim 1 , wherein each of the first pattern and the second pattern comprises a hollow portion, and a proportion of the hollow portion in the first pattern is smaller than a proportion of the hollow portion in the second pattern.

10. The display device of claim 1 , wherein the light shielding pattern comprises a plurality of strips, and a density of the strips in the first pattern is greater than a density of the strips in the second pattern.

11. The display device of claim 1 , wherein a material forming the light shielding pattern comprises ink.

12. The display device of claim 1 , wherein a width of the light shielding pattern in a direction perpendicular to an edge of a display area closest to the light shielding pattern ranges from 0.5 mm to 1 mm.

13. The display device of claim 3 , wherein at least a part of the orthographic projection of the light shielding pattern on the display panel is located within a middle area between the display area of the display panel and the orthographic projection of the border pattern on the display panel.

14. The display device of claim 1 , wherein the display device further comprises a fanout area in the non-display area, the plurality of signal leading lines are gathered in the fanout area, and an orthographic projection of the light shielding pattern on the display panel is located within the fanout area.

15. The display device of claim 1 , wherein an orthographic projection of the border pattern on the display panel surrounds the display area, and an area of a region surrounded by the orthographic projection of the border pattern on the display panel is greater than an area of the display area.
