Abstract

An image display device having a plurality of selfluminous pixels, for displaying an image by selectively making the pixels luminous is disclosed. The image display device includes: the pixels each divided into a plurality of small light-emitting sections; an ejection-direction selecting section that deflects the light emitted from the small light-emitting sections at predetermined angles according to the position of the small light-emitting sections in the pixel; and controller that selectively makes only small light-emitting sections that emit light that can reach the viewer luminous on the basis of viewer-position information indicative of the position of the viewer.

Claims

1. An image display device having a plurality of selfluminous pixels, for displaying an image by selectively making the pixels luminous, the image display device comprising:

the pixels each divided into a plurality of small light-emitting sections;

an ejection-direction selecting section that ejects the light emitted from the small light-emitting sections at predetermined angles according to the position of the small light-emitting sections in the pixel; and

a controller that selectively makes only small light-emitting sections that emit light that can reach the viewer luminous on the basis of viewer-position information indicative of the position of the viewer.

3. The image display device according to claim 1, wherein:

the plurality of small light-emitting sections are divided into a plurality of groups which can emit the light in different colors; and

the luminescent light of any one of the small light-emitting sections of each group can reach the viewer who is present in a predetermined position.

4. The image display device according to claim 3, wherein the groups each have at least five small light-emitting sections.

5. The image display device according to claim 3, wherein the plurality of groups is arranged in the vertical direction in the pixel.

6. The image display device according to claim 3, wherein the plurality of groups are arranged in the horizontal direction in the pixel.

7. The image display device according to claim 3, wherein:

the difference between the luminance in the case where the luminescent lights of both adjacent small light-emitting sections in the same group reach the viewer who is in a predetermined place and the luminance in the case where the luminescent light of any one of adjacent small light-emitting sections in the same group reaches the viewer who is in a predetermined place is set within 50 percent.

8. The image display device according to claim 1, wherein at least part of the small light-emitting sections that can emit light to the viewer who is present in a predetermined position is arranged along the same straight line.

9. The image display device according to claim 1, wherein the emission-direction selecting section ejects the light emitted from the small light-emitting section closer to the central axis of the display surface as the small light-emitting section is located closer to the end of the image display surface.

10. The image display device according to claim 1, wherein the emission-direction selecting section is a cylindrical lens.

11. The image display device according to claim 1, wherein the luminous intensity of the small light-emitting section is variable.

12. The image display device according to claim 1, wherein the small light-emitting section is an organic electroluminescence device.

13. The image display device according to claim 1 wherein the relative position of the pixel to the emission-direction selecting section is movable.

2. An image display device comprising a viewer-position sensor that acquires the viewer-position information.
