Abstract

An organic light emitting diode display having a flat region having a flat surface, and curved regions disposed at left and right sides of the flat region and formed in curved surfaces, having a display panel including a substrate, which maintains a flat surface in the flat region, and is formed in curved surfaces in the curved regions, and organic light emitting diodes disposed on the substrate, a window disposed in the flat region and the curved regions on the display panel, and a cover member disposed under the display panel, in which the cover member includes a flat cover member disposed in the flat region and curved cover members disposed in the curved regions, and the flat cover member and the curved cover member are formed of different materials or have different thicknesses.

Claims

1. An organic light emitting diode display having a flat region having a flat surface, and curved regions disposed at left and right sides of the flat region and formed in curved surfaces, comprising:

a display panel including a substrate having a flat surface in the flat region, and curved surfaces in the curved regions, and organic light emitting diodes disposed on the substrate;

a window disposed in the flat region and the curved regions on the display panel; and

a cover member disposed under the display panel,

wherein the cover member includes a flat cover member disposed in the flat region and curved cover members disposed in the curved regions, and

the flat cover member and the curved cover member are formed of different materials or have different thicknesses.

2. The organic light emitting diode display of claim 1, wherein the cover member is formed of a cushion or a sponge.

3. The organic light emitting diode display of claim 2, wherein the flat cover member and the curved cover member have different thicknesses.

4. The organic light emitting diode display of claim 3, wherein a thickness of the curved cover member is larger than a thickness of the flat cover member by about 1.5 times to about 3 times.

5. The organic light emitting diode display of claim 4, wherein the flat cover member and the curved cover member are formed of the same material.

6. The organic light emitting diode display of claim 2, wherein the flat cover member and the curved cover member are formed of different materials.

7. The organic light emitting diode display of claim 6, wherein a density of the flat cover member is larger than a density of the curved cover member by about 3 times to about 10 times.

8. The organic light emitting diode display of claim 7, wherein the flat cover member and the curved cover member have the same thickness.

9. The organic light emitting diode display of claim 1, further comprising a touch panel disposed between the display panel and the window.

10. The organic light emitting diode display of claim 9, wherein the touch panel is disposed in the flat region and the curved regions.

11. The organic light emitting diode display of claim 1, wherein the curved regions extend from the flat region.

12. The organic light emitting diode display of claim 11, wherein the flat region and the curved regions are configured to display an image.
