Abstract

Disclosed is a flexible display that is slim for flexibility, is controlled in stiffness, and has improved reliability owing to a structure of a non-folding portion thereof.

First claim

The invention claimed is:

1. A flexible display comprising:
a display panel;
a plate having a first surface facing a surface of the display panel and a second surface facing away from the surface of the display panel, the plate being divided into at least one folding portion and a non-folding portion adjacent to the folding portion; and
a plurality of first fasteners coupled to the second surface of the plate at a predetermined interval apart from each other along a boundary of the folding portion and the non-folding portion,
wherein each of the first fasteners includes a body portion having a first height and a flange coupled to the body portion, the flange having a second height less than the first height.

2. The flexible display according to claim 1 , wherein each of the first fasteners is a metal bolt positioned on the second surface of the plate.

3. The flexible display according to claim 1 , wherein the body portion and the flange of each fasteners are on the second surface of the plate.

4. The flexible display according to claim 1 , wherein a first side of the flange is coupled to the body and a second side of the flange is coupled to the second surface of the plate.

5. The flexible display according to claim 1 , wherein the plate has a plurality of openings in the folding portion extending through the first and second surfaces of the plate.

6. The flexible display of claim 5 , wherein the plurality of openings extend from a first end of the folding portion to a second end of the folding portion.

7. The flexible display according to claim 1 , further comprising:
a supporter having an area that is less than an area of the plate, the supporter fully overlapping the plate.

8. The flexible display according to claim 7 , wherein the supporter has a stiffness greater than a stiffness of the plate.

9. The flexible display according to claim 1 , further comprising at least one second fastener positioned at a corner of the second surface of the plate, wherein the second fastener is located in the non-folding portion and is not adjacent to the folding portion.

10. The flexible display according to claim 1 , wherein the flange is welded and fixed to the second surface of the plate by a continuous hole in the plate and the flange.

11. The flexible display according to claim 1 , further comprising:
a case structure to receive the display panel, the plate, and the plurality of first fasteners.

12. The flexible display according to claim 11 , wherein the body and the flange of each of first fasteners face an inner surface of the case structure.
