Abstract

An apparatus for attaching a display panel includes a panel mount which receives a panel bottom cover facing corner portions of the display panel which are extended bent from a front surface of the display panel, and a pressing module which provides a pressing force to the panel bottom cover which is received in the panel mount and faces the corner portions of the display panel. The pressing module includes a pressing pad which applies the pressing force to the panel bottom cover at the corner portions of the display panel to attach the panel bottom cover to the display panel at the corner portions thereof.

First claim

What is claimed is:

1. An apparatus for attaching a display panel, comprising:
a panel mount which receives the display panel including a plurality of surfaces, the surfaces comprising:
a front surface including first to fourth sides,
a first side surface extending from the first side of the front surface in a first direction,
a second side surface extending from the second side of the front surface in a second direction which crosses the first direction,
a third side surface extending from the third side of the front surface in the first direction,
a fourth side surface extending from the fourth side of the front surface in the second direction,
a first corner portion between the first side surface and the second side surface, a second corner portion between the second side surface and the third side surface,
a third corner portion between the third side surface and the fourth side surface, and
a fourth corner portion between the first side surface and the fourth side surface; and

a pressing module which provides a pressing force to a panel bottom cover which faces the plurality of surfaces of the display panel, the pressing module comprising:
a pressing pad which applies the pressing force to the panel bottom cover at the first to fourth corner portions of the display panel, to attach the panel bottom cover to the display panel at the first to fourth corner portions thereof, and
the pressing pad comprising:
a first pressing portion corresponding to the first side surface of the display panel;
a second pressing portion corresponding to the second side surface of the display panel;
a third pressing portion corresponding to the third side surface of the display panel;
a fourth pressing portion corresponding to the fourth side surface of the display panel;
a first corner-pressing portion corresponding to the first corner portion of the display panel, and disposed between the first pressing portion and the second pressing portion;
a second corner-pressing portion corresponding to the second corner portion of the display panel, and disposed between the second pressing portion and the third pressing portion;
a third corner-pressing portion corresponding to the third corner portion of the display panel, and disposed between the third pressing portion and the fourth pressing portion; and
a fourth corner-pressing portion corresponding to the fourth corner portion of the display panel, and disposed between the fourth pressing portion and the first pressing portion.

2. The apparatus of claim 1 , wherein the pressing module further comprises:
a pressing bracket to which the pressing pad is fixed,
each of the pressing pad and the pressing bracket having a hardness, and
the hardness of the pressing pad lower than the hardness of the pressing bracket.

3. The apparatus of claim 2 , wherein
the pressing pad comprises silicon, and
the pressing bracket comprises a metal.

4. The apparatus of claim 1 , wherein the pressing pad has a quadrangular frame shape.

5. An apparatus for attaching a display panel, comprising
a panel mount which receives the display panel including a plurality of corner portions; and
a pressing module which provides a pressing force to a panel bottom cover which faces the plurality of corner portions of the display panel,
wherein
the pressing module comprises a pressing pad which applies the pressing force to the panel bottom cover at the corner portions of the display panel to attach the panel bottom cover to the display panel at the corner portions thereof, and
the pressing pad comprises:
a first pressing pad and a second pressing pad extending along a first direction and facing each other along a second direction which intersects the first direction; and
a third pressing pad and a fourth pressing pad extending along the second direction and facing each other along the first direction,
wherein the first pressing pad, the second pressing pad, the third pressing pad and the fourth pressing pad are disconnected from one another at corner portions of the pressing pad which correspond to the corner portions of the display panel.

6. The apparatus of claim 5 , wherein
each of the first pressing pad, the second pressing pad, the third pressing pad and the fourth pressing pad has a first end and a second end which is opposite to the first end,
at a first corner portion of the pressing pad, the first end of the third pressing pad is adjacent to the first end of the first pressing pad,
at a second corner portion of the pressing pad, the second end of the third pressing pad is adjacent to the first end of the second pressing pad,
at a third corner portion of the pressing pad, the first end of the fourth pressing pad is adjacent to the second end of the first pressing pad, and
at a fourth corner portion of the pressing pad, the second end of the fourth pressing pad is adjacent to the second end of the second pressing pad.

7. The apparatus of claim 6 , wherein each of the first end and the second end of the first pressing pad, the first end and the second end of the second pressing pad, the first end and the second end of the third pressing pad, and the first end and the second end of the fourth pressing pad has a triangular shape in a plan view.

8. The apparatus of claim 6 , wherein the pressing pad further comprises:
at the first corner portion of the pressing pad, a first corner pressing pad adjacent to the first end of the first pressing pad and the first end of the third pressing pad;
at the second corner portion of the pressing pad, a second corner pressing pad adjacent to the first end of the second pressing pad and the second end of the third pressing pad;
at the third corner portion of the pressing pad, a third corner pressing pad adjacent to the second end of the first pressing pad and the first end of the fourth pressing pad; and
at the fourth corner portion of the pressing pad, a fourth corner pressing pad adjacent to the second end of the second pressing pad and the second end of the fourth pressing pad.

9. The apparatus of claim 8 , wherein each of the first corner-pressing pad, the second corner-pressing pad, the third corner-pressing pad and the fourth corner-pressing pad has a triangular shape in a plan view.

10. The apparatus of claim 2 , wherein the pressing module further comprises:
the pressing bracket including a first bracket and a second bracket which face each other with the pressing pad therebetween,
a first air passage hole penetrating the first bracket,
a second air passage hole penetrating the second bracket, and
the first air passage hole of the first bracket aligned with the second air passage hole of the second bracket.

11. The apparatus of claim 2 , wherein the pressing module further comprises:
the pressing bracket including a first bracket and a second bracket which face each other with the pressing pad therebetween, and
a fixing member which fixes the first bracket to the second bracket.

12. The apparatus of claim 11 , wherein
the first bracket defines a first fixing hole through which the fixing member is fixed to the first bracket, and
the second bracket defines a second fixing hole which penetrates the second bracket and through which the fixing member extends to be fixed to the first bracket at the first fixing hole thereof.

13. The apparatus of claim 1 , wherein
the pressing module further comprises a pressing bracket to which the pressing pad is fixed, and
the pressing pad further comprises a fixing portion fixed to the pressing bracket at an inside of the pressing bracket,
wherein the pressing portion extends from a distal end of the fixin
