Abstract

A display module includes: a substrate including a mounting surface on which a plurality of inorganic light-emitting diodes emitting light in a first direction are mounted, a side surface, and a rear surface being opposite to the mounting surface; a front cover bonded with the mounting surface and covering the mounting surface in the first direction; a metal plate bonded with the rear surface; a side cover surrounding the side surface; and a side end member covering at least one portion of the side cover and extending in a second direction being orthogonal to the first direction along the side surface, wherein the side end member includes a body extending in the second direction, and a plurality of ribs extending from the body in the first direction and arranged at intervals along the second direction.

Claims (49)

1. A display module comprising:

a substrate having a mounting surface on which a plurality of inorganic light-emitting diodes emitting light in a first direction are mounted, a side surface, and a rear surface being opposite to the mounting surface;

a metal plate bonded with the rear surface of the substrate;

a side cover surrounding the side surface of the substrate; and

a side end member covering at least one portion of the side cover, and extending along the side surface of the substrate in a second direction that is orthogonal to the first direction,

wherein the side end member comprises a body extending in the second direction, and a plurality of ribs extending from the body in the first direction and arranged at intervals along the second direction.

2. The display module of claim 1 , wherein the side cover comprises:

a side end portion forming a side end of the side cover, and

a rear portion extending in a rear direction from the side end portion with respect to the first direction and positioned at an inner location than the side end portion in a third direction that is orthogonal to the first direction and the second direction, and

wherein the body is provided on the rear portion in the third direction.

3. The display module of claim 2 , wherein the plurality of ribs are provided on the side end portion.

4. The display module of claim 2 , wherein the plurality of ribs are provided on the side end portion in the third direction and the rear portion in the third direction.

5. The display module of claim 4 , wherein the body is formed at rear ends of the plurality of ribs.

6. The display module of claim 1 , wherein a length of each of the plurality of ribs in the second direction is equal to or less than a length of a separation distance between the plurality of ribs in the second direction.

7. The display module of claim 1 , wherein a conductivity of the side end member is greater than a conductivity of the side cover.

8. The display module of claim 1 , wherein a color of the side end member is a black color.

9. The display module of claim 1 , wherein the side end member comprises a metal material.

10. A display module comprising:

a substrate having a mounting surface on which a plurality of inorganic light-emitting diodes are mounted, a side surface, and a rear surface being opposite to the mounting surface;

a front cover bonded with the mounting surface of the substrate and covering the mounting surface of the substrate;

a metal plate bonded with the rear surface of the substrate;

a side cover surrounding the side surface of the substrate; and

a side end member covering at least one portion of the side cover and at least one portion of the metal plate, the side end member comprising a first end portion, a second end portion spaced from the first end portion in a direction in which the mounting surface faces, and a side end portion extending from the first end portion to the second end portion and forming a side end;

wherein the first end portion of the side end member covers at least one portion of the side end of the side cover,

wherein the second end portion of the side end member contacts the metal plate and is grounded to the metal plate, and

wherein the side end portion comprises mountains and valleys alternately arranged in the direction in which the mounting surface faces.

11. The display module of claim 10 , wherein a mountain from among the mountains is provided at the first end portion, and

wherein a valley among the valleys is provided at the second end portion.

12. The display module of claim 10 , wherein a conductivity of the side end member is greater than a conductivity of the side cover.

13. The display module of claim 10 , wherein a height of each of the mountains and a depth of each of the valleys are the same.

14. The display module of claim 13 , wherein the mountains and the valleys have a same volume.

15. A display apparatus comprising:

a display module array comprising a plurality of display modules arranged in a matrix, wherein each of the plurality of display modules comprises:

a substrate having a mounting surface on which a plurality of inorganic light-emitting diodes in a first direction are mounted, a side surface, and a rear surface being opposite to the mounting surface;

a front cover bonded with the mounting surface of the substrate and covering the mounting surface of the substrate;

a metal plate bonded with the rear surface of the substrate;

a side cover surrounding the side surface of the substrate; and

a side end member covering at least one portion of the side cover and extending along the side surface of the substrate in a second direction that is orthogonal to the first direction,

wherein the side end member comprises a body extending in the second direction, and a plurality of ribs extending from the body in the first direction and arranged at intervals along the second direction.

16. The display apparatus of claim 15 , wherein the plurality of display modules comprises a first display module and a second display module, and

wherein the side end member of the first display module engages the side end member of the second display module.

17. The display apparatus of claim 16 , wherein a length of each of the plurality of ribs in the second direction is equal to or less than a length of a separation distance between the plurality of ribs in the second direction.

18. The display apparatus of claim 16 , wherein the side cover comprises:

a side end portion forming a side end of the side cover, and

a rear portion extending in a rear direction from the side end portion with respect to the first direction and in a third direction that is orthogonal to the first direction and the second direction, and

wherein the body is provided on the rear portion.

19. The display apparatus of claim 18 , wherein the plurality of ribs are provided on the side end portion.

20. The display apparatus of claim 18 , wherein the plurality of ribs are provided on the side end portion in the third direction and the rear portion in the third direction.
