Abstract

A display device includes a liquid crystal display part and a light control part. The liquid crystal display part is configured to have an array of pixels each including a plurality of segments each driven independently. Further, the light control part is configured to control light coming from or directed to the liquid crystal display part. In a first display mode provided by the display device, a plurality of pixel signals derived from different items of pixel information are supplied respectively to the plurality of segments in each of the pixels.

Claims

1. A display device comprising:

a liquid crystal display part configured to have an array of pixels each including a plurality of segments each driven independently; and

a light control part configured to control light coming from or directed to said liquid crystal display part,

wherein, in a first display mode provided by said display device, a plurality of pixel signals derived from different items of pixel information are supplied respectively to said plurality of segments in each of said pixels.

2. The display device according to claim 1, wherein said different items of pixel information correspond to different perspective images.

3. The display device according to claim 1, wherein said different items of pixel information are in different positions corresponding to either the same perspective image or different perspective images.

4. The display device according to claim 1, further comprising a display drive part configured to have a plurality of intensity correction tables corresponding respectively to said plurality of segments in each of said pixels, said display drive part driving said liquid crystal display part by correcting said pixel information using said plurality of intensity correction tables.

5. The display device according to claim 4, wherein said plurality of intensity correction tables are equivalent to each other, and

wherein said display drive part generates a pixel signal based on the pixel information corresponding to each of said segments.

6. The display device according to claim 4, wherein, in a second display mode provided by said display device, said plurality of intensity correction tables are different from one another, and

wherein said display drive part generates a pixel signal based on the pixel information corresponding to each of said pixels.

7. The display device according to claim 1, wherein said light control part constitutes a barrier part configured to let pass or block light, and

wherein said barrier part has a plurality of first-group liquid crystal barriers and a plurality of second-group liquid crystal barriers of which an opened state and a closed state may be switched.

8. The display device according to claim 7, wherein

in said first display mode, said plurality of first-group liquid crystal barriers are turned into a transparent state and said plurality of second-group liquid crystal barriers are turned into a blocked state to display a plurality of perspective images, and

in said second display mode, said plurality of first-group liquid crystal barriers and said plurality of second-group liquid crystal barriers are turned into the transparent state to display one perspective image.

9. The display device according to claim 1, wherein

said light control part constitutes a barrier part configured to let pass or block light, and

said barrier part has a plurality of fixed openings.

10. The display device according to claim 1, wherein said light control part has a plurality of variable lenses of which the refractive index can be switched.

11. The display device according to claim 1, wherein said light control part has a plurality of fixed lenses.

12. The display device according to claim 1, wherein said plurality of segments are vertically arrayed in each of said pixels.

13. The display device according to claim 1, wherein said plurality of segments are horizontally arrayed in each of said pixels.

14. The display device according to claim 1, wherein each of said pixels has two segments.

15. The display device according to claim 1, wherein each of said segments is formed by a plurality of domains of which the orientation directions of liquid crystal molecules are different from one another.

16. The display device according to claim 1, further comprising a backlight part,

wherein said liquid crystal display part is interposed between said backlight part and said light control part.

17. The display device according to claim 1, further comprising a backlight part,

wherein said light control part is interposed between said backlight part and said liquid crystal display part.

18. A display method comprising:

supplying, in a first display mode, a plurality of pixel signals derived from different items of pixel information respectively to a plurality of segments which are included in each of pixels and driven independently for display execution;

causing each of said segments to execute display based on said pixel signals, and

controlling light coming from or directed to each of said segments.

19. An electronic apparatus comprising:

a display device; and

a control part configured to perform operation control using said display device;

wherein said display device includes

a liquid crystal display part configured to have an array of pixels each including a plurality of segments each driven independently, and
