Abstract

A display apparatus is disclosed that includes a display panel and a controller. The display panel includes a first edge extending in a first direction, a second edge extending in a second direction that intersects the first direction, and a display area where an image is displayed. The controller is configured to obtain information to bend the display panel and, in response, to bend the display panel to a bent display panel. In the bent display panel, the first edge has a first display-panel curvature and the second edge has a second display-panel curvature.

First claim

What is claimed is:

1. A display apparatus comprising:
a display panel comprising a first edge extending in a first direction, a second edge extending in a second direction that intersects the first direction, and a display area where an image is displayed;
a controller configured to obtain information to bend the display panel and, in response, to bend the display panel to a bent display panel; and
a frame assembly located behind the display panel and configured to bend the display panel under control of the controller,
wherein in the bent display panel, the first edge has a first display-panel curvature and the second edge has a second display-panel curvature,
wherein the frame assembly comprises a first frame and a second frame,
wherein the first frame extends in the first direction and is configured to bend the display panel from the first direction to a third direction that intersects the first direction and the second direction by contracting the first frame,
wherein the second frame extends in the second direction and is configured to bend the display panel from the second direction to the third direction by contracting the second frame.

2. The display apparatus of claim 1 , wherein the display area comprises a central display area, and a corner display area located between the central display area and a corner where the first edge and the second edge meet each other,
wherein, in the bent display panel, the corner display area is bent from the first direction to a third direction that intersects the first direction and the second direction, and is bent from the second direction to the third direction.

3. The display apparatus of claim 2 , wherein the corner display area comprises a first corner display area and a second corner display area,
wherein, in the bent display panel, the first corner display area comprises a first curvature in a cross-section in the first direction, and a second curvature in a cross-section in the second direction, and
the second corner display area comprises a third curvature in a cross-section in the first direction, and a fourth curvature in a cross-section in the second direction,
wherein the first curvature and the third curvature are different from each other.

4. The display apparatus of claim 1 , wherein the information obtained to bend the display panel comprises at least one of a first information corresponding to a manipulation of a remote controller connected to the display apparatus, a second information corresponding to a voice signal of a user who watches the image, and a third information based on a type of content included in the image.

5. The display apparatus of claim 1 , wherein the information obtained to bend the display panel comprises location information of at least one user who watches the image.

6. The display apparatus of claim 1 , wherein the frame assembly further comprises a plurality of supporters supporting the display panel, extending in the first direction, and spaced apart from one another in the second direction,
wherein the first frame is further configured to bend the plurality of supporters from the first direction to the third direction.

7. The display apparatus of claim 1 , wherein the frame assembly further comprises a plurality of supporters supporting the display panel, extending in the first direction, and spaced apart from one another in the second direction,
wherein the second frame is further configured to move at least one of the plurality of supporters in the third direction.

8. The display apparatus of claim 1 , wherein the frame assembly further comprises a plurality of supporters supporting the display panel, extending in the first direction, and spaced apart from one another in the second direction,
wherein the display apparatus further comprises a cushion layer between the display panel and the plurality of supporters.

9. The display apparatus of claim 1 , wherein the display panel further comprises a through-portion passing through the display panel.

10. A method of controlling a display apparatus, the method comprising:
displaying an image in a display area of a display panel comprising a first edge extending in a first direction and a second edge extending in a second direction that intersects the first direction;
obtaining information to bend the display panel;
bending the display panel so that the first edge has a first display-panel curvature and the second edge has a second display-panel curvature by considering the obtained information;
bending a first frame located behind the display panel and extending in the first direction, from the first direction to a third direction that intersects the first direction and the second direction by contracting the first frame; and
bending a second frame located behind the display panel and extending in the second direction, from the second direction to the third direction by contracting the second frame.

11. The method of claim 10 , wherein the display area comprises a central display area, and a corner display area located between the central display area and a corner where the first edge and the second edge meet each other,
wherein the bending of the display panel comprises bending the corner display area from the first direction to a third direction that intersects the first direction and the second direction, and bending the corner display area from the second direction to the third direction.

12. The method of claim 11 , wherein the corner display area comprises a first corner display area and a second corner display area,
wherein the first corner display area comprises a first curvature in a cross-section in the first direction and a second curvature in a cross-section in the second direction, and
the second corner display area comprises a third curvature in a cross-section in the first direction and a fourth curvature in a cross-section in the second direction,
wherein the first curvature and the third curvature are different from each other.

13. The method of claim 10 , wherein the information obtained to bend the display panel comprises at least one of a first information corresponding to a manipulation of a remote controller connected to the display apparatus, a second information corresponding to a voice signal of a user who watches the image, and a third information based on a type of content included in the image.

14. The method of claim 10 , wherein the information obtained to bend the display panel comprises location information of at least one user who watches the image.

15. The method of claim 10 , further comprising bending, from the first direction to the third direction, a plurality of supporters supporting the display panel, extending in the first direction, and spaced apart from one another in the second direction.

16. The method of claim 10 , further comprising moving, in the third direction, at least one of a plurality of supporters supporting the display panel, extending in the first direction, and spaced apart from one another in the second direction.

17. The method of claim 10 , further comprising rotating the display panel using the second direction as an axis.

18. The method of claim 10 , further comprising changing a shape of a through-portion passing through the display panel.
