Abstract

A display device is disclosed. The display device includes a housing, a roller located within the housing, a display panel having a front surface for displaying a screen and a back surface facing the front surface, the display panel being wound on the roller, and a plate wound on the roller, and coupled to back surface of the display panel, the plate having an opening.

Claims

1. A display device, comprising:

a housing;

a roller located within the housing;

a display panel comprising a front surface and a rear surface; and

a plate coupled to the back surface of the display panel and comprising an opening,

wherein the display panel and the plate are wound on the roller,

wherein the plate further comprises a plurality of openings arranged in a plurality of rows which are aligned along a longitudinal direction of the roller, and

wherein positions of openings of a first row are offset with respect to positions of openings of a second row adjacent to the first row such that adjacent openings of the first row are separated by plate material which is vertically aligned with a center of an opening of the adjacent second row.

2. The display device of claim 1, wherein the plate comprises a metal material.

3. The display device of claim 1, wherein the plurality of rows are separated by rows of plate material each having a same height, wherein adjacent rows of plate material are connected by bars of plate material separating the plurality of openings.

4. The display device of claim 1, wherein:

the plurality of openings are elongated slits; and

a first length of a first opening of the first row of the plurality of rows is greater than a second length of the second opening of an adjacent second row of the plurality of rows.

5. The display device of claim 1, wherein sizes of openings of a first row of the plurality of rows are the same as sizes of openings of an adjacent second row of the plurality of rows.

6. The display device of claim 1, wherein the plurality of openings form a pattern such that corresponding bars of plate material between corresponding openings in every other row of the plurality of rows are vertically aligned.

7. The display device of claim 1, wherein each of the plurality of openings is rectangularly shaped.

8. The display device of claim 1, wherein each of the plurality of openings is an elongated slit formed to be elongated in a direction parallel to the roller.

9. The display device of claim 1, wherein the rear surface of the display panel and the plate are coupled via an adhesive layer.

10. The display device of claim 1, wherein the plate and the display panel are wound on the roller in a direction such that a rear surface of the plate is positioned toward the roller.

11. The display device of claim 1, wherein plate and the display panel are wound on the roller in a direction such that the front surface of the display panel is positioned toward the roller.

12. The display device of claim 1, further comprising a first resin layer disposed at a rear surface of the plate which covers the opening of the plate.

13. The display device of claim 12, wherein:

each of the plurality of openings is an elongated slit formed to be elongated in a direction parallel to the roller;

the first resin layer is flexible and configured to be wound on the roller; and

each of the plurality of openings is filled in by the first resin layer,

wherein the plate and the display panel are wound on the roller in a direction such that the first resin layer is positioned toward the roller.

14. The display device of claim 12, wherein the first resin layer is configured to cover the entire plate such that the plate is not externally exposed.

15. The display device of claim 12, further comprising a second resin layer disposed at the rear surface of the display panel, wherein the plate is disposed between the first resin layer and the second resin layer.

16. The display device of claim 12, wherein the first resin layer comprises a urethane or rubber material.

17. A display device comprising:

a housing;

a roller located within the housing;

a display panel comprising a front surface and a rear surface; and

a plate coupled to the back surface of the display panel and comprising an opening,

wherein;

the display panel and the plate are wound on the roller;

the plate further comprises a plurality of openings arranged in a plurality of rows which are aligned along a longitudinal direction of the roller;

the plurality of openings are elongated slits;

a first opening disposed at an end of a first row of the plurality of rows is open-ended toward a lateral edge of the plate; and

a second opening disposed at an end of a second row adjacent to the first row is open-ended toward the lateral edge of the plate,

wherein a length of the first opening is greater than a length of the second opening.

18. The display device of claim 17, wherein the plate comprises a metal material.

19. A display device comprising:

a housing;

a roller located within the housing;

a display panel comprising a front surface and a rear surface; and

a plate coupled to the back surface of the display panel and comprising an opening,

wherein;

the plate further comprises a plurality of openings arranged in a plurality of rows;

positions of openings of a first row are offset with respect to positions of openings of a second row adjacent to the first row; and

a first bar of plate material between a first opening and a second opening of the first row is vertically aligned with a second bar of plate material between a third opening and a fourth opening of a third row,

wherein the second row is between the first row and the third row.

20. The display device of claim 19, wherein the plate comprises a metal material.
