Abstract

A curved display device may include a display panel and a chassis member. The display panel may include a first edge and a second edge. The first edge may be longer than the second edge and may be convex in a back direction. The second edge may be convex in an image-displaying direction. The back direction and the image-displaying direction may be with reference to the display panel. The chassis member may be coupled to the display panel and may support the display panel.

First claim

What is claimed is:

1. A curved display device comprising:
a display panel including a first edge and a second edge, wherein the first edge is longer than the second edge and is convex in a back direction, wherein the second edge is convex in an image-displaying direction, and wherein the back direction and the image-displaying direction are with reference to the display panel; and
a chassis member coupled to the display panel and supporting the display panel.

2. The curved display device of claim 1 , wherein the chassis member comprises a first surface portion and a second surface portion, wherein both the first surface portion and the second surface portion overlap a peripheral portion of the display panel, wherein the first surface portion is convex in the back direction, and wherein the second surface portion is convex in the image-displaying direction.

3. The curved display device of claim 1 , wherein the chassis member includes a convex support surface, wherein a curvature of the convex support surface corresponds to a curvature of the second edge.

4. The curved display device of claim 3 , wherein the chassis member includes a flat surface that overlaps the convex support surface.

5. The curved display device of claim 1 , wherein the first edge includes a curved section that has a constant curvature.

6. The curved display device of claim 1 , wherein the first edge includes consecutive curved sections having gradually increasing or decreasing curvatures, and wherein the first edge includes a straight section directly connected to one of the consecutive curved sections.

7. The curved display device of claim 1 , wherein a curved section of the first edge matches a curved section of a sine wave.

8. The curved display device of claim 1 , wherein the second edge includes a curved section that has a constant curvature.

9. The curved display device of claim 1 , wherein the second edge includes consecutive curved sections having gradually increasing or decreasing curvatures, and wherein the second edge includes a straight section directly connected to one of the consecutive curved sections.

10. The curved display device of claim 1 , wherein a curved section of the second edge matches a curved section of a sine wave.

11. The curved display device of claim 1 , wherein a maximum depth of the second edge relative to two opposite ends of the second edge depends on a length of the second edge.

12. The curved display device of claim 11 , wherein the maximum depth of the second edge is equal to or less than 0.15% of the length of the second edge.

13. The curved display device of claim 1 , wherein a maximum depth of the second edge relative to two opposite ends of the second edge depends on a maximum depth of the first edge relative to two opposite ends of the first edge.

14. The curved display device of claim 13 , wherein the maximum depth of the second edge is equal to or less than 0.62% of the maximum depth of the first edge.

15. The curved display device of claim 1 , wherein the display panel includes:
a pixel unit including pixels;
data lines;
scan lines;
a data driver for providing data signals to the pixels through the data lines;
a scan driver for providing scan signals to the pixels through the scan lines; and
a timing controller for controlling operations of the data driver and the scan driver.

16. The curved display device of claim 1 , wherein the display panel is positioned between a center of the curvature of the first edge and a center of the curvature of the second edge.

17. The curved display device of claim 1 , wherein a central section of the first edge corresponds to a curved section of a sine wave.

18. The curved display device of claim 1 , wherein a central section of the second edge corresponds to a curved section of a sine wave.
