Abstract

A curved display apparatus and a multi display system having the same are provided. The curved display apparatus includes a display panel, and a fixation member which fixes the display panel so that the display panel is curved with multiple curvatures.

First claim

What is claimed is:

1. A curved display apparatus, comprising:
a display panel; and
a fixation member with multiple curvatures in a part of the fixation member which supports the display panel so that the display panel is curved with multiple curvatures,
wherein the fixation member includes a center portion corresponding to a center portion of the display panel, peripheral portions corresponding to peripheral portions of the display panel, and intermediate portions corresponding to intermediate portions of the display panel, each of the intermediate portions of the fixation member connecting the center portion of the fixation member and a peripheral portion of the peripheral portions of the fixation member,
wherein the multiple curvatures include a curvature of the center portion of the fixation member, curvatures of the peripheral portions of the fixation member and curvatures of the intermediate portions of the fixation member,
wherein the curvatures of the peripheral portions of the fixation member are symmetric with reference to the center portion of the fixation member, and
wherein the multiple curvatures of the fixation member are set to decrease along a direction away from the center portion of the fixation member towards each of the peripheral portions of the fixation member.

2. The curved display apparatus of claim 1 , wherein the display panel is a liquid crystal display (LCD) panel, and the curved display apparatus further comprises a direct-type backlight assembly which provides the LCD panel with light, wherein
the direct-type backlight assembly includes a plurality of light sources arranged on a rear side of the LCD panel.

3. The curved display apparatus of claim 1 , wherein the fixation member comprises:
an upper frame which corresponds to an upper side of the display panel and which supports the display panel so that the display panel is curved with the multiple curvatures;
a lower frame which corresponds to a lower side of the display panel and which supports the display panel so that the display panel is curved with the multiple curvatures;
a left frame which corresponds to a left side of the display panel and which is disposed between the upper frame and the lower frame; and
a right frame which corresponds to a right side of the display panel and which is disposed between the upper frame and the lower frame.

4. The curved display apparatus of claim 3 , wherein the upper frame comprises a first opening formed therein to receive the upper side of the display panel, and the lower frame comprises a second opening formed therein to receive the lower side of the display panel, the left frame comprises a third opening formed therein to receive the left side of the display panel, and the right frame comprises a fourth opening formed therein to receive the right side of the display panel.

5. The curved display apparatus of claim 1 , wherein the fixation member comprises:
a bottom chassis arranged below the display panel; and
a top chassis arranged above the display panel, the top chassis comprising multiple curvatures and fixing the display panel via coupling with the bottom chassis.

6. The curved display apparatus of claim 1 , wherein the fixation member comprises:
a bottom chassis arranged below the display panel;
a molding member arranged between the display panel and the bottom chassis, the molding member comprising multiple curvatures which support the display panel; and
a top chassis arranged above the display panel, the top chassis comprising multiple curvatures and fixing the display panel via coupling with the bottom chassis.

7. The curved display apparatus of claim 1 , wherein the fixation member comprises:
a bottom chassis arranged below the display panel;
a molding member arranged between the display panel and the bottom chassis, the molding member comprising multiple curvatures which support the display panel; and
an adhesive member arranged between the molding member and the display panel to fix the display panel with the multiple curvatures to the molding member.

8. The curved display apparatus of claim 1 , wherein the multiple curvatures are defined by a plurality of radii of curvature which increase in a direction moving farther away from the center portion of the fixation member.

9. The curved display apparatus of claim 1 , wherein the multiple curvatures are defined by a plurality of radii of curvature which change in a direction moving farther away from the center portion of the fixation member.

10. The curved display apparatus of claim 1 , wherein the fixation member comprises:
first and second members which respectively support the display panel at front and rear locations of the display panel so that the display panel is curved with multiple curvatures, wherein
the first and second members each provide support so that a first region of the display panel maintains a first curvature, a second region on a left side of the first region maintains a second curvature which is smaller than the first curvature, and a third region on a right side of the first region maintains a third curvature which is smaller than the first curvature.

11. The display apparatus of claim 10 , wherein the first member comprises a first supporting surface to be in contact with a front surface of the display panel, and the second member comprises a second supporting surface to be in contact with a rear surface of the display panel, and
the first and second supporting surfaces each comprise:
a first supporting region having the first curvature and corresponding to the first region,
a second supporting region having the second curvature and corresponding to the second region, and
a third supporting region having the third curvature and corresponding to the third region.

12. The display apparatus of claim 11 , wherein the first and second supporting surfaces having the first, second and third supporting regions formed thereon each comprise:
a fourth supporting region arranged between the first and second supporting regions and having a fourth curvature which is larger than the first curvature; and
a fifth supporting region arranged between the first and third supporting regions and having a fifth curvature which is larger than the first curvature.

13. The display apparatus of claim 10 , wherein the second member comprises a supporting surface to contact a front surface of the display panel, and the supporting surface comprises a first supporting region having the first curvature and corresponding to the first region, a second supporting region having the second curvature and corresponding to the second region, and a third supporting region having the third curvature and corresponding to the third region, and
the first member is deformed by a force to couple the first member into tight contact with the second member so as to bring the display panel into tight contact with the supporting surface of the second member.

14. A curved display apparatus, comprising:
a flexible display panel; and
a fixation member supporting the flexible display panel so that the flexible display panel is curved with multiple curvatures,
wherein the fixation member includes a plurality of guide members according to which the flexible display panel is curved with the multiple curvatures,
wherein the fixation member comprises a support opening which has a larger width than a thickness of the flexible display panel and into which a part of the flexible display panel is inserted,
wherein a maximum thickness of each of the plurality of guide members is a difference between the width of the support opening and the thickness of
