Abstract

A panel flattening assembly includes a first fixing assembly and a second fixing assembly respectively disposed at a first corner and a second corner adjacent to the first corner in a first direction on a rear surface of a display panel; a first supporting member disposed between the first fixing assembly and the second fixing assembly and spaced apart from the display panel; a first displacement adjusting member connected to the first fixing assembly and adjusting a distance between the first fixing assembly and a first end of the first supporting member by adjusting a displacement of the first fixing assembly; and a second displacement adjusting member connected to the second fixing assembly and adjusting a distance between the second fixing assembly and a second end of the first supporting member by adjusting a displacement of the second fixing assembly.

First claim

What is claimed is:

1. A panel flattening assembly comprising:
a first fixing assembly and a second fixing assembly respectively disposed at a first corner and a second corner adjacent to the first corner in a first direction on a rear surface of a display panel;
a first supporting member disposed between the first fixing assembly and the second fixing assembly and spaced apart from the display panel;
a first displacement adjusting member connected to the first fixing assembly and adjusting a distance between the first fixing assembly and a first end of the first supporting member by adjusting a displacement of the first fixing assembly; and
a second displacement adjusting member connected to the second fixing assembly and adjusting a distance between the second fixing assembly and a second end of the first supporting member by adjusting a displacement of the second fixing assembly.

2. The panel flattening assembly of claim 1 , wherein the first fixing assembly comprises:
a first fixing member attached to the first corner on the rear surface of the display panel; and
a second fixing member connected to the first fixing member with the first displacement adjusting member disposed between the second fixing member and the first fixing member.

3. The panel flattening assembly of claim 2 , wherein the first displacement adjusting member comprises:
a first screw protruding toward the second fixing assembly and having a protrusion connected to the first supporting member.

4. The panel flattening assembly of claim 3 , wherein the first fixing member and the second fixing member include grooves into which part of the first screw is inserted so that movement other than rotation of the first screw is restricted within the first fixing assembly.

5. The panel flattening assembly of claim 3 , wherein by rotation of the first screw,
the first screw and the first fixing assembly are moved together in the first direction or in a direction opposite to the first direction, and
the distance between the first fixing assembly and the first end of the first supporting member is adjusted.

6. The panel flattening assembly of claim 3 , wherein the second displacement adjusting member comprises:
a second screw protruding toward the first fixing assembly and having a protrusion connected to the first supporting member.

7. The panel flattening assembly of claim 6 , wherein by rotation of the second screw,
the second screw and the second fixing assembly are moved together in the first direction or in a direction opposite to the first direction, and
the distance between the second fixing assembly and the second end of the first supporting member is adjusted.

8. The panel flattening assembly of claim 6 , further comprising:
a third fixing assembly disposed at a third corner adjacent to the first corner in a second direction on the rear surface of the display panel; and
a second supporting member disposed between the first fixing assembly and the third fixing assembly and spaced apart from the display panel.

9. The panel flattening assembly of claim 8 , further comprising:
a third displacement adjusting member disposed on the second fixing member and adjusting a distance between the first fixing assembly and a first end of the second supporting member by adjusting the displacement of the first fixing assembly.

10. The panel flattening assembly of claim 9 , wherein
the first fixing assembly further includes a third fixing member disposed on the third displacement adjusting member and the second fixing member, and
the third displacement adjusting member includes a third screw protruding toward the third fixing assembly and having a protrusion connected to the second supporting member.

11. The panel flattening assembly of claim 10 , wherein the second fixing member and the third fixing member include grooves into which part of the third screw is inserted so that movement other than rotation of the third screw is restricted within the first fixing assembly.

12. The panel flattening assembly of claim 9 , further comprising:
a fourth fixing assembly disposed at a fourth corner adjacent to the second corner in the second direction on the rear surface of the display panel;
a third supporting member disposed between the third fixing assembly and the fourth fixing assembly and spaced apart from the display panel;
a fourth supporting member disposed between the second fixing assembly and the fourth fixing assembly and spaced apart from the display panel;
a fourth displacement adjusting member connected to the third fixing assembly and a second end of the second supporting member;
a fifth displacement adjusting member connected to the third fixing assembly and a first end of the third supporting member;
a sixth displacement adjusting member connected to the fourth fixing assembly and a second end of the third supporting member;
a seventh displacement adjusting member connected to the second fixing assembly and a first end of the fourth supporting member; and
an eighth displacement adjusting member connected to the fourth fixing assembly and a second end of the fourth supporting member.

13. The panel flattening assembly of claim 8 , wherein the second supporting member is directly connected to the first fixing assembly and the third fixing assembly.

14. The panel flattening assembly of claim 1 , wherein
the first displacement adjusting member includes a first spring member disposed between the first fixing assembly and the first end of the first supporting member, and
the second displacement adjusting member includes a second spring member disposed between the second fixing assembly and the second end of the first supporting member.

15. The panel flattening assembly of claim 1 , wherein the first fixing assembly and the second fixing assembly include a magnetic material.

16. A display module comprising:
a display panel including a substrate;
a panel flattening assembly attached to a corner portion on a rear surface of the display panel;
a circuit plate disposed on the panel flattening assembly; and
a back cover covering the rear surface of the display panel, the panel flattening assembly, and the circuit plate,
wherein the panel flattening assembly comprises:
a first fixing assembly and a second fixing assembly respectively disposed at a first corner and a second corner adjacent to the first corner in a first direction on the rear surface of the display panel;
a first supporting member disposed between the first fixing assembly and the second fixing assembly and spaced apart from the display panel;
a first displacement adjusting member connected to the first fixing assembly and adjusting a distance between the first fixing assembly and a first end of the first supporting member by adjusting a displacement of the first fixing assembly; and
a second displacement adjusting member connected to the second fixing assembly and adjusting a distance between the second fixing assembly and a second end of the first supporting member by adjusting a displacement of the second fixing assembly.

17. The display module of claim 16 , wherein the first fixing assembly comprises:
a first fixing member attached to the first corner on the rear surface of the display panel; and
a second fixing member connected to the first fixing member with the first displacement adjusting member disposed between the second fixing member and the first fixing member.

18. The display module of claim 17 , wherein the first displacement adjusting member comprises:
a first screw protr
