Abstract

A display assembly has a planar region and an edge bending region that are connected to each other. The display assembly includes a display panel, and a first support portion fixedly connected to a portion of the display panel located in the edge bending region. The first support portion includes a plurality of first support bars, and the plurality of first support bars are spaced apart in a width direction of the edge bending region. Materials of the plurality of first support bars are rigid materials.

First claim

What is claimed is:

1. A display assembly having a planar region and at least one edge bending region that are connected to each other, and the display assembly comprising:
a display panel; and
at least one first support portion fixedly connected to a portion of the display panel located in an edge bending region; wherein
the at least one edge bending region is located in at least one edge of the display panel;
a first support portion includes a plurality of first support bars, and the plurality of first support bars are spaced apart in a width direction of the edge bending region;
shapes of side faces of the plurality of first support bars are different; and
materials of the plurality of first support bars are rigid materials.

2. The display assembly according to claim 1 , wherein a width of a first support bar is in a range of 0.2 mm to 1 mm, inclusive.

3. The display assembly according to claim 1 , wherein
the first support portion further includes a plurality of second support bars; the plurality of first support bars and the plurality of second support bars are alternately arranged in the width direction of the edge bending region, and any adjacent first support bar and second support bar are fixedly connected; and
materials of the plurality of second support bars are elastic materials.

4. The display assembly according to claim 3 , wherein a width of a second support bar is in a range of 0.2 mm to 1 mm, inclusive.

5. The display assembly according to claim 3 , wherein
the first support potion further includes at least one support layer, and a support layer is disposed on a first surface or a second surface of a whole formed by the plurality of first support bars and the plurality of second support bars, the first surface is a surface of the whole formed by the plurality of first support bars and the plurality of second support bars that is proximate to a display surface of the display panel, and the second surface is a surface of the whole formed by the plurality of first support bars and the plurality of second support bars that is away from the display surface of the display panel; and
a material of the support layer is an elastic material.

6. The display assembly according to claim 5 , wherein
the at least one support layer and the plurality of second support bars are of an integral structure.

7. The display assembly according to claim 1 , wherein
the display panel is bent to a back surface of the first support portion around the first support portion, the back surface of the first support portion is a surface of the first support portion away from a display surface of the display panel, and surfaces of the first support portion that are proximate to and away from the display surface of the display panel are both fixedly connected to the display panel.

8. The display assembly according to claim 1 , wherein
the portion of the display panel located in the edge bending region adheres to the first support portion through an adhesive layer; and
in the edge bending region, an outer edge of the adhesive layer is closer to the planar region than an outer edge of the first support portion, the outer edge of the adhesive layer is an edge of the adhesive layer away from the planar region, and the outer edge of the first support portion is an edge of the first support portion away from the planar region.

9. The display assembly according to claim 1 , wherein
a portion of the first support portion extends to the planar region.

10. The display assembly according to claim 1 , wherein a thickness of the first support portion is approximately 2.5 to 15 times a thickness of the display panel.

11. The display assembly according to claim 1 , further comprising a second support portion, wherein
the second support portion is fixedly connected to a portion of the at least one first support portion located in the edge bending region, and the second support portion is attached to a portion of the display panel located in the planar region; and
a material of the second support portion is a rigid material.

12. A display apparatus, comprising:
the display assembly according to claim 1 ;
a cover plate; and
an optically clear adhesive layer located between the display assembly and the cover plate, and the cover plate and a display surface of the display assembly adhering through the optically clear adhesive layer.

13. A display assembly having a planar region and at least one edge bending region that are connected to each other, and the display assembly comprising:
a display panel; and
at least one first support portion fixedly connected to a portion of the display panel located in an edge bending region; wherein
the at least one edge bending region is located in at least one edge of the display panel;
the at least one first support portion is in a curved shape with a preset radian;
a material of a first support portion is an elastic material, and an elastic modulus of the first support portion is greater than an elastic modulus of the display panel.

14. The display assembly according to claim 13 , wherein
the display panel is bent to a back surface of the first support portion around the first support portion, the back surface of the first support portion is a surface of the first support portion away from a display surface of the display panel, and surfaces of the first support portion that are proximate to and away from the display surface of the display panel are both fixedly connected to the display panel.

15. The display assembly according to claim 13 , wherein
the portion of the display panel located in the edge bending region adheres to the first support portion through an adhesive layer; and
in the edge bending region, an outer edge of the adhesive layer is closer to the planar region than an outer edge of the first support portion; the outer edge of the adhesive layer is an edge of the adhesive layer away from the planar region, and the outer edge of the first support portion is an edge of the first support portion away from the planar region.

16. The display assembly according to claim 13 , wherein
a portion of the first support portion extends to the planar region.

17. The display assembly according to claim 13 , wherein a thickness of the first support portion is approximately 2.5 to 12.5 times a thickness of the display panel.

18. The display assembly according to claim 13 , further comprising a second support portion, wherein
