Abstract

A display device includes: a display panel which displays an image; and a frame set disposed on a rear side of the display panel, where the frame set bends the display panel. The frame set includes a frame including a body extending in a longitudinal direction and a head protruding toward the rear side of the display panel from the body, and a wire fixed to the head and extending in a longitudinal direction of the frame.

First claim

What is claimed is:

1. A display device comprising:
a display panel which displays an image; and
a frame set disposed on a rear side of the display panel, wherein the frame set bends the display panel,
wherein the frame set comprises a frame including a body extending in a longitudinal direction and a head protruding toward the rear side of the display panel from the body, and a wire fixed to the head and extending in a longitudinal direction of the frame,
wherein the body is in an unbent state when the display panel is in a flat state, and
wherein the wire is disposed between the display panel and the body.

2. The display device of claim 1 , wherein
the frame further includes a protrusion pattern protruding toward the rear side of the display panel from the body,
the protrusion pattern is apart from the head in the longitudinal direction of the frame,
a through hole is defined through the protrusion pattern, and
the wire extends through the through hole.

3. The display device of claim 1 , wherein
the frame set further comprises an intermediate frame disposed between the frame and the display panel, wherein the intermediate frame extends in the longitudinal direction of the frame, and moves relative to the head,
one of the head and the intermediate frame comprises a concave portion facing the other one of the head and the intermediate frame, and
the other one of the head and the intermediate frame comprises a convex portion facing the concave portion.

4. The display device of claim 1 , wherein
the display panel comprises a first edge extending in a first direction, and a second edge extending in a second direction crossing the first direction,
the frame set comprises a plurality of frame sets,
the plurality of frame sets comprise a first frame set extending in the first direction, and a second frame set extending in the second direction, and
the first frame set and the second frame set bend the display panel in a way such that each of the first edge and the second edge each has a curvature.

5. The display device of claim 4 , further comprising:
a plurality of supporters which supports the display panel and is arranged side by side in the second direction,
wherein the first frame set bends the plurality of supporters, and
the second frame set moves at least one selected from the plurality of supporters in a third direction crossing the first direction and the second direction.

6. The display device of claim 5 , wherein
the plurality of supporters comprise a first supporter and a second supporter adjacent to each other, and
the first supporter and the second supporter are connected to each other.

7. The display device of claim 5 , wherein an extension direction of each of the plurality of supporters is changed at least twice.

8. The display device of claim 4 , wherein
the display panel comprises a central display area, and a corner display area disposed between the central display area and a corner where the first edge and the second edge meet, and
when the display panel is bent, the corner display area is bent from the first direction to a third direction crossing the first direction and the second direction, and is bent from the second direction to the third direction.

9. The display device of claim 1 , further comprising:
a controller which adjusts a length of the wire,
wherein the frame is bent when the length of the wire decreases.

10. A control method of a display device, the method comprising:
displaying an image on a display panel of the display device; and
bending the display panel by bending a frame set of the display device, wherein the frame set is disposed on a rear side of the display panel,
wherein the frame set comprises: a frame including a body extending in a longitudinal direction, and a head protruding to the rear side of the display panel from the body, wherein the body is in an unbent state when the display panel is in a flat state; and a wire fixed to the head and extending in a longitudinal direction of the frame, and
the frame is bent by adjusting a length of the wire,
wherein the wire is disposed between the display panel and the body.

11. The control method of claim 10 , wherein
the frame set further comprises an intermediate frame disposed between the frame and the display panel and extending in the longitudinal direction of the frame, and
the intermediate frame moves relative to the head when the frame is bent.

12. The control method of claim 11 , wherein
one of the head and the intermediate frame comprises a concave portion facing the other one of the head and the intermediate frame,
the other one of the head and the intermediate frame includes a convex portion facing the concave portion, and
when the frame is bent, the convex portion moves relative to the concave portion in the concave portion.

13. The control method of claim 10 , wherein
the display panel comprises a first edge extending in a first direction, and a second edge extending in a second direction crossing the first direction,
the frame set comprises a plurality of frame sets,
the plurality of frame sets comprise a first frame set extending in the first direction, and a second frame set extending in the second direction, and
the bending the display panel comprises bending the display panel by bending at least one selected from the first frame set and the second frame set.

14. The control method of claim 13 , wherein the first frame set and the second frame set bend the display panel in way such that each of the first edge and the second edge has a curvature.

15. The control method of claim 13 , further comprising:
bending a plurality of supporters of the display device by bending the first frame set, wherein the plurality of supporters supports the display panel and is arranged side by side in the second direction.

16. The control method of claim 13 , further comprising:
moving at least one selected from a plurality of supporters in a third direction crossing the first direction and the second direction by bending the second frame set, wherein the plurality of supporters supports the display panel and is arranged side by side in the second direction.

17. The control method of claim 13 , wherein
the display panel comprises a central display area, and a corner display area disposed between the central display area and a corner where the first edge and the second edge meet, and
the bending the display panel comprises bending the corner display area from the first direction to a third direction crossing the first direction and the second direction, and bending the corner display area from the second direction to the third direction.

18. The control method of claim 17 , wherein
the corner display area comprises a first corner display area and a second corner display area,
when the display panel is bent, the first corner display area has a first-direction first-curvature in a cross-section in the first direction, and a second-direction first-curvature in a cross-section in the second direction,
when the display panel is bent, the second corner display area has a first-direction second-curvature in a cross-section in the first direction, and a second-direction second-curvature in a cross-section in the second direction, and
the first-direction first-curvature is different from the first-direction second-curvature.

19. The control method of claim 10 , further comprising:
obtaining information for bending the display panel,
wherein the display panel is bent in a shape corr
