Abstract

A display includes a display panel having elements that allow attachment to a mounting structure therebehind and in alignment with adjacent display panels that collectively form a tiled display screen that has multiple display panels connected to each other with effectively seamless bezels. The elements are configured to allow the display panel to be attached to or detached from the tiled display screen in a particular direction other than a side direction that would only allow for engagement from the sides of the adjacent display panels.

Claims

1. A tiled display device, comprising:

a plurality of display panels;

a plate to which the plurality of display panels are attached in a tiled manner;

a first coupling unit on a rear side of each display panel; and

a second coupling unit on a front side of the plate and operatively attachable or detachable with the first coupling unit,

wherein at least one among the first coupling unit and the second coupling unit includes a magnet, and wherein the first coupling unit comprises;

a body having a cylindrical shape to guide the second coupling unit received therein; and

a coupling groove on an inner surface of the body.

2. The tiled display device according to claim 1, wherein the rear surface of the display panel includes a metallic material which reacts with magnetism.

3. The tiled display device according to claim 1, wherein the display panel includes a LED display panel.

4. The tiled display device according to claim 1, wherein the second coupling unit comprises:

a guide on the plate and received in the body of the first coupling unit;

a movable member in the guide, the movable member being received in the body of the first coupling unit and movable therein;

a first tiling magnet at an end portion of the movable member and used to secure the display panel; and

an elastic member between the plate and the movable member.

5. The tiled display device according to claim 4, further comprising:

a second tiling magnet at an end portion of the body of the first coupling unit, and cooperating with the first tiling magnet to move the movable member, when the first coupling unit and the second coupling unit are coupled with each other.

6. The tiled display device according to claim 4, wherein the first tiling magnet is attached with the display panel as the guide is coupled with the body.

7. The tiled display device according to claim 4, wherein the movable member is moved in a direction facing the plate as the guide is separated from the body.

8. The tiled display device according to claim 4, wherein the guide includes a plurality of through holes.

9. The tiled display device according to claim 8, wherein the through holes are arranged along a circumference of a cross-section of the guide.

10. The tiled display device according to claim 8, wherein the guide further includes coupling members disposed in the through holes, respectively, and a thickness of each coupling members is larger than a depth of each through hole.

11. The tiled display device according to claim 10, wherein the movable member includes a receiving groove formed on an outer wall thereof.

12. The tiled display device according to claim 11, wherein at least a part of the coupling members are disposed in the coupling groove as the guide is coupled with the body.

13. The tiled display device according to claim 11, wherein at least a part of the coupling members are disposed in the receiving groove as the guide is coupled with the body.

14. The tiled display device according to claim 11, wherein, upon attachment of the display panel to the plate, the second coupling unit is received in the first coupling unit, the movable member is moved and the coupling member is received in the receiving groove of the movable member and coupled to the coupling groove.

15. The tiled display device according to claim 11, wherein, upon detachment of the display panel from the plate, the second coupling unit is separated from the first coupling unit, the movable member is moved, and the coupling member is received in the receiving groove of the movable member and decoupled from the coupling groove.
