Abstract

Provided is a display module comprising: a display module; a fastening bracket which is disposed at the rear surface of the display module; a resin which couples the fastening bracket and the display module to each other; a module holder which is disposed at the rear surface of the display module; and a fastener which passes through the module holder in the direction from the rear to front of the module holder and is coupled to the fastening bracket, wherein when the fastener is decoupled from the fastening bracket, the module holder is separated from the display module.

First claim

The invention claimed is:

1. A display device comprising:
a display module including a fastening bracket located on a rear surface of the display module;
a resin coupling the fastening bracket and the display module to each other;
a module holder located on the rear surface of the display module; and
a fastener that passes forward through a rear surface of the module holder and coupled to the fastening bracket,
wherein, when the fastener is separated from the fastening bracket, the module holder is separated from the display module,
wherein a plurality of display modules are fastened to a front surface of the module holder,
wherein the plurality of display modules include a first display module having a first thickness and a second display module having a second thickness greater than the first thickness, and
wherein an amount of a first resin of the first display module is greater than an amount of a second resin of the second display module.

2. The display device of claim 1 ,
wherein the plurality of display modules are arranged with front surfaces defining a same plane.

3. The display device of claim 1 , further comprising a fastening boss formed on the rear surface of the display module,
wherein the fastening bracket includes a nut inserted into the fastening boss, and
the resin is located in an empty space between the nut and the fastening boss.

4. The display device of claim 3 , wherein a portion of the fastener, which protrudes to the front surface of the module holder, is less than a thickness of the fastening bracket.

5. The display device of claim 3 , further comprising a stopper inserted into a front surface of the nut after the fastener and the nut are fastened to each other.

6. The display device of claim 1 , further comprising an elastic ring inserted between the fastening bracket and the module holder.

7. The display device of claim 1 , further comprising:
a resin hole formed in the fastening bracket; and
an injection port formed in the module holder at a position corresponding to the resin hole,
wherein the resin is filed in the resin hole.

8. A method of assembling a display device, the method comprising:
accommodating a display module including a fastening boss formed on a rear surface of the display module, a front surface of the display module being in contact with an assembly table;
inserting a fastener into a rear surface of a module holder and fastening a nut to an end of the fastener, which protrudes forward;
injecting a resin into the fastening boss; and
stacking the module holder on the rear surface of the display module to insert the nut into the fastening boss.

9. The method of claim 8 , wherein a plurality of display modules are arranged in a grid, and
the module holder covers rear surfaces of the plurality of display modules and includes fastening bosses of the plurality of display modules, a plurality of fasteners inserted thereinto, and nuts respectively inserted.

10. The method of claim 9 , wherein an injected amount of the resin is adjusted depending on a thickness of the display module.

11. The method of claim 8 , wherein the fastener is released from the nut to separate the display module, the resin, and the nut from the module holder, and
another display module is fastened to the module holder.

12. The method of claim 11 , wherein the another display module includes a fastening boss formed on a rear surface thereof and a nut inserted into the fastening boss, and
the display module further includes an elastic ring between the fastening boss or the nut and the module holder.

13. A method of assembling a display device, the method comprising:
accommodating a display module with a front surface being in contact with an assembly table;
fastening a fastener passing through a module holder and coupling a fastening bracket to a front surface of the module holder;
accommodating the fastening bracket and the module holder on a rear surface of the display module; and
injecting a resin into a resin hole formed in the fastening bracket to couple the fastening bracket and the display module to each other,
wherein the module holder further includes an injection port connected to the resin hole.

14. The method of claim 13 , wherein a plurality of display modules are arranged in a grid,
the module holder covers rear surfaces of the plurality of display modules, and
the display module further includes an elastic ring between the fastening bracket and the module holder.
