Abstract

A display device includes: a display panel curved in one direction; and a lower frame configured to accommodate the display panel. The lower frame includes: a plurality of bottom portions having a predetermined curvature; a side portion bent and extending from an edge portion of the bottom portion; and at least one connecting unit configured to connect the plurality of bottom portions.

First claim

What is claimed is:

1. A display device comprising:
a display panel curved in one direction; and
a lower frame configured to accommodate the display panel, wherein the lower frame comprises:
a plurality of bottom portions having a curvature corresponding to the display panel, each bottom portion having a side portion bent and extending from an edge portion of the bottom portion; and
at least one connecting unit configured to connect the plurality of bottom portions, the connecting unit comprising a first connecting unit configured to connect the plurality of bottom portions and a second connecting unit configured to connect the side portions.

2. The display device of claim 1 , wherein the connecting unit has a curvature corresponding to the display panel.

3. The display device of claim 2 , wherein the connecting unit has substantially the same curvature as the bottom portions.

4. The display device of claim 1 , wherein the connecting unit has a groove into which a free edge of the bottom portion is inserted.

5. The display device of claim 4 , further comprising a coupling member configured to fix the bottom portion to the connecting unit.

6. The display device of claim 4 , wherein the lower frame has a height difference between the free edge of the bottom portion inserted to the groove and the rest of the bottom portion.

7. The display device of claim 1 , wherein the first and second connecting units have grooves into which a free edge of the bottom portion and a free end of the side portion are respectively inserted.

8. The display device of claim 1 , wherein the connecting unit is integrally formed by press molding.

9. The display device of claim 1 , wherein the connecting unit comprises at least one of aluminum (Al), iron (Fe), stainless steel, and alloys thereof.

10. A display device comprising:
a display panel curved in one direction;
a lower frame configured to accommodate the display panel, the lower frame comprising:
a plurality of bottom portions having a curvature corresponding to the display panel, each bottom portion having at least one free edge; and
a side portion orthogonally extending from remaining edge portions of the bottom portion, each side portion having at least one free end;
a first connecting unit configured to accommodate the free edge of each bottom portion to connect the plurality of bottom portions to each other via the first connecting unit; and
a second connecting unit orthogonally extending from the first connecting unit, the second connecting unit configured to accommodate the free end of each side portion to connect the side portions to each other via the second connecting unit.

11. The display device as set forth in claim 10 , the first connecting unit having insert grooves on opposite edges thereof to respectively accommodate the free edge of each bottom portion.

12. The display device as set forth in claim 10 , the second connecting unit having insert grooves on opposite edges thereof to respectively accommodate the free end of each side portion.

13. A display device comprising:
a curved display panel;
a curved lower frame configured to accommodate the display panel, the lower frame comprising:
a first bottom portion having a curvature corresponding to the curved display panel, the first bottom portion having a free edge;
a second bottom portion having a curvature corresponding to the curved display panel, the second bottom portion having a free edge;
first to third side portions orthogonally extending from remaining edge portions of the first bottom portion, the first and third side portions each having one free end; and
fourth to sixth side portions orthogonally extending from remaining edge portions of the second bottom portion, the fourth and sixth side portions each having one free end;
a first connecting unit configured to accommodate the free edges of the first and second bottom portions to connect the first and second bottom portions to each other via the first connecting unit;
a second connecting unit orthogonally extending from a first end of the first connecting unit, the second connecting unit configured to accommodate the free ends of the first and fourth side portions to connect the first and fourth side portions to each other via the second connecting unit; and
a third connecting unit orthogonally extending from a second end of the first connecting unit, the third connecting unit configured to accommodate the free ends of the third and sixth side portions to connect the third and sixth side portions to each other via the third connecting unit.

14. The display device as set forth in claim 13 , the first connecting unit having insert grooves on opposite edges thereof to respectively accommodate the free edge of the first and second bottom portions.

15. The display device as set forth in claim 13 , the second connecting unit having insert grooves on opposite edges thereof to respectively accommodate the free ends of the first and fourth side portions; and
the third connecting unit having insert grooves on opposite edges thereof to respectively accommodate the free ends of the third and sixth side portion.

16. The display device as set forth in claim 13 , the first connecting unit having a curvature corresponding to the curved display.
