Abstract

This display device comprises: a plurality of display panels arranged in a grid pattern; a fastening bracket coupled to the respective rear surfaces of the plurality of display panels; a module holder coupled to the fastening bracket by means of a resin; a control unit located on the rear surface of the module holder; and a back cover that covers the control unit and is fastened to the module holder. Since the coupling position of a display module between the fastening bracket and the module holder can be set differently for each of display modules, stepped portions and gaps between the display modules can be reduced.

First claim

The invention claimed is:

1. A display device comprising:
a plurality of display panels arranged in a grid pattern;
a fastening bracket coupled to a back surface of each of the plurality of display panels:
a module holder coupled to the fastening brackets by a resin:
a controller disposed on a back side of the module holder; and
a back cover arranged to cover the controller and coupled to the module holder.

2. The display device of claim 1 , wherein the fastening bracket comprises:
a first fastening portion coupled to a back surface of each of the display panels; and
a second fastening portion protruding away from the back surface of each of the display panels and coupled to the module holder by the resin.

3. The display device of claim 2 , wherein front surfaces of the plurality of display panels are arranged in the same plane.

4. The display device of claim 3 , wherein the plurality of display panels comprises a first display panel having a first thickness and a second display panel having a second thickness, the second thickness being greater than the first thickness,
wherein the first fastening portion of the fastening bracket disposed on the back surface of the first display panel and the second fastening portion of the fastening bracket disposed on the back surface of the second display panel are arranged to have a step therebetween and are coupled to the module holder at different positions in a thickness direction.

5. The display device of claim 2 , wherein the second fastening portion is disposed around a perimeter of the back surface of each of the display panels,
wherein the module holder comprises a third fastening portion disposed laterally in parallel with the second fastening portion,
wherein the resin is injected into a space between the second fastening portion and the third fastening portion.

6. The display device as in claim 5 , wherein the second fastening portion is segmented into a plurality of pieces along the perimeter of each of the display panels,
wherein the third fastening portion comprises a fastening hole allowing the second fastening portion to extend therethrough,
wherein the fastening hole has a length corresponding to a length of the second fastening portion.

7. The display device of claim 6 , wherein the fastening hole comprises a inclined surface or stepped portion having a wide back side and a narrow front side.

8. The display device of claim 2 , further comprising:
an adhesive tape arranged between the first fastening portion and each of the display panels.

9. The display device of claim 2 , wherein the second fastening portion is perpendicular to the first fastening portion.
