Abstract

Provided is a display apparatus. The display apparatus includes a display panel, a back cover disposed on a rear side of the display panel, the back cover having a curved shape of which both ends protrude forward, and a fixing part fixing the back cover to maintain the curved shape of the back cover. The display panel is curved in a shape corresponding to that of the back cover.

First claim

What is claimed is:

1. A display apparatus, comprising:
a display module having a curved shape in a horizontal direction;
a back cover disposed behind the display module to cover a rear surface of the display module and having a curved shape corresponding to the display module;
a middle cover, at least a portion of the middle cover being disposed between the display module and the back cover and having a curved shape corresponding to the display module; and
a fixing bar horizontally disposed on the back cover and having a curved shape corresponding to the back cover,
wherein the fixing bar has a cross-section in a vertical direction that includes a plurality of bent portions, and the plurality of bent portions extend horizontally,
wherein the plurality of bent portions of the fixing bar includes:
a first portion;
a second portion bent at a first end of the first portion; and
a third portion bent at a second end of the first portion,
wherein at least one of the plurality of bent portions is configured to contact a surface of the back cover, and
wherein at least one slit is formed in the fixing bar to enable the fixing bar to be easily curved, and
wherein the middle cover includes:
an insertion portion, a first end of which being inserted between the display module and the back cover; and
an end cover portion that is bent at a second end of the insertion portion, and extends in a front direction to be positioned at a side surface of the display module,
wherein an outer surface of the end cover portion of the middle cover is exposed without being covered by the back cover.

2. The display apparatus of claim 1 , wherein the middle cover further includes a stepped portion at a rear surface thereof on which an upper end portion of the back cover is mounted.

3. The display apparatus of claim 2 , wherein the back cover includes a stepped portion at a front surface thereof on which the insertion portion is mounted.

4. The display apparatus of claim 1 , wherein an outer surface of the end cover portion of the middle cover is rounded.

5. The display apparatus of claim 1 , further comprising a plurality of holes formed in the first portion of the fixing bar.

6. The display apparatus of claim 1 , wherein a portion of the back cover is bent several times to form a rib portion,
wherein the rib portion extends in a widthwise direction of the display module.

7. The display apparatus of claim 1 , wherein the fixing bar is provided in plurality,
wherein the plurality of fixing bars are arranged in parallel, and
wherein the plurality of fixing bars are arranged vertically or horizontally.

8. The display apparatus of claim 1 , wherein the back cover includes a rib that protrudes from the back cover and extending horizontally.

9. The display apparatus of claim 8 , wherein the rib has a curved shape corresponding to the curved shape of the back cover.

10. A display apparatus, comprising:
a display module having a curved shape in a horizontal direction;
a back cover disposed behind the display module to cover a rear surface of the display module and having a curved shape corresponding to the display module;
a middle cover, at least a portion of the middle cover being disposed between the display module and the back cover;
a fixing bar horizontally disposed on the back cover and having a curved shape corresponding to the back cover; and
wherein the fixing bar has a cross-section in a vertical direction that includes a plurality of bent portions, the plurality of bent portions extending horizontally,
wherein the plurality of bent portions of the fixing bar includes:
a first portion;
a second portion bent at a first end of the first portion; and
a third portion bent at a second end of the first portion,
wherein at least one of the plurality of bent portions is configured to contact a surface of the back cover,
wherein the first portion is configured to form a vertical surface of the fixing bar,
wherein the first end of the first portion is an upper end of the first portion,
wherein the second portion is configured to be bent at the upper end of the first portion,
wherein the second end of the first portion is a lower end of the first portion,
wherein the third portion is configured to be bent at the lower end of the first portion, and
wherein at least one slit is formed at a position where the second portion is bent from the upper end of the first portion, and
wherein the middle cover includes:
an insertion portion, a first end of which being inserted between the display module and the back cover; and
an end cover portion that is bent at a second end of the insertion portion, and extends in a front direction to be positioned at a side surface of the display module,
wherein an outer surface of the end cover portion of the middle cover is exposed without being covered by the back cover.

11. The display apparatus of claim 10 , further comprising:
a stand configured to be received on an installation surface; and
a supporter having a first end connected to the stand and a second end connected to the back cover.

12. The display apparatus of claim 11 , further comprising a rear cover.

13. The display apparatus of claim 10 , wherein the middle cover further includes a stepped portion at a rear surface thereof on which an upper end portion of the back cover is mounted.

14. The display apparatus of claim 10 , wherein the back cover includes a stepped portion at a front surface thereof on which the insertion portion is mounted.

15. The display apparatus of claim 10 , wherein an outer surface of the end cover portion of the middle cover is rounded.

16. The display apparatus of claim 10 , further comprising a plurality of holes formed in the first portion of the fixing bar.

17. The display apparatus of claim 10 , wherein a portion of the back cover is bent several times to form a rib portion,
wherein the rib portion extends horizontally in a widthwise direction of the display module.

18. The display apparatus of claim 10 , wherein the back cover includes a rib that protrudes from the back cover and extending horizontally.

19. The display apparatus of claim 18 , wherein the rib has a curved shape corresponding to the curved shape of the back cover.

20. A display apparatus, comprising:
a display module having a curved shape in a horizontal direction;
a back cover disposed behind the display module to cover a rear surface of the display module and having a curved shape corresponding to the display module;
a middle cover, at least a portion of the middle cover being disposed between the display module and the back cover and having a curved shape corresponding to the display module; and
a support structure horizontally disposed on the back cover and having a curved shape corresponding to the back cover,
wherein the support structure has a cross-section in a vertical direction that includes a plurality of bent portions, the plurality of bent portions extending horizontally,
