Abstract

A curved display device comprising a continuous, curved, concave viewing surface having a surface width W greater than or equal to 48 cm and less than or equal to 200 cm, and wherein a distance D from the center of a straight line segment which connects the centers of the display edges in the width dimension, to the center of the display surface in the horizontal dimension is less than or equal to ((0.215W)−6.5).

Claims

1. A curved desktop display device comprising a continuous, curved, concave, non-immersive viewing surface having a horizontal radius of curvature that varies from the center of the viewing surface to the display edges in the width dimension, and having a surface width W greater than or equal to 48 cm and less than or equal to 200 cm, and wherein a distance D from the center of a straight line segment which connects the centers of the display edges in the width dimension, to the center of the display surface in the horizontal dimension is less than or equal to ((0.215 W)−

6.5 cm); and

wherein the display device is an OLED display.

2. The curved desktop display device of claim 1, wherein D is within 10 percent of ((0.215 W)−

8.9 cm).

3. The curved desktop display device of claim 1, wherein D is equal to or greater than 1 cm.

4. The curved desktop display device of claim 3, wherein D is greater than 0 and equal to or greater than ((0.215 W)−

14.5 cm).

5. The curved desktop display device of claim 1, wherein the horizontal radius of curvature of the continuous curved concave non-immersive viewing surface decreases from the center of the viewing surface to the display edges in the width dimension.

6. The curved desktop display device of claim 1, wherein the horizontal radius of curvature of the continuous curved concave non-immersive viewing surface has a first or second derivative with respect to distance from the display center that varies monotonically.

7. The curved desktop display device of claim 1, wherein the display is horizontally symmetric about the center of the display.

8. The curved desktop display device of claim 1, wherein the ratio of the horizontal width of the display surface to the height of the display surface is greater than 1.8.

9. The curved desktop display device of claim 1, wherein the radius of curvature is constant over a portion of the surface.

10. The curved desktop display device of claim 1, wherein the viewing surface has a constant vertical radius of curvature.

11. The curved desktop display device of claim 1, wherein the viewing surface has no curvature in the vertical direction.

12. The curved desktop display device of claim 1, wherein W is from 60 to 100 cm.

13. The curved desktop display device of claim 1, wherein the display device is a tiled display.

14. The curved desktop display device of claim 1, wherein the display device is an active-matrix display.

15. The curved desktop display device of claim 1, further comprising pixel elements on the concave side of the curved display surface.
