Abstract

There is provided a display device including a display part including a pixel of a first series having a first horizontal pixel width and a pixel of a second series having a second horizontal pixel width smaller than the first horizontal pixel width, the pixels of the first series and the pixels of the second series being arrayed alternately in each of a horizontal direction and a vertical direction, and a light beam control part that controls a light beam from the display part or a light beam toward the display part.

Claims

1. A display device, comprising:

a display part including a pixel of a first series having a first horizontal pixel width and a pixel of a second series having a second horizontal pixel width smaller than the first horizontal pixel width, the pixels of the first series and the pixels of the second series being arrayed alternately in each of a horizontal direction and a vertical direction; and

a light beam control part that controls a light beam from the display part or a light beam toward the display part.

2. The display device according to claim 1, wherein

the display device has a plurality of display modes including a first display mode and a second display mode,

in the first display mode, the pixels of the first series and the pixels of the second series display a single image, and

in the second display mode, the pixels of the first series display a plurality of images and the pixels of the second series display a black color.

3. The display device according to claim 2, wherein the distance between the pixels of the first series in the horizontal direction is equal to the first horizontal pixel width.

4. The display device according to claim 2, wherein the distance between the pixels of the first series in the horizontal direction is smaller than the first horizontal pixel width.

5. The display device according to claim 2, wherein the distance between the pixels of the first series in the horizontal direction is larger than the first horizontal pixel width.

6. The display device according to claim 3, wherein a central coordinate in the horizontal direction of each pixel of the first series is equal to a central coordinate in the horizontal direction of a pixel of the second series neighboring on the pixel of the first series in the vertical direction.

7. The display device according to claim 1, wherein

the display device has a plurality of display modes including a first display mode and a second display mode,

in the first display mode, the pixels of the first series and the pixels of the second series display a single image, and

in the second display mode, the pixels of the first series display a plurality of images and the pixels of the second series display a gray color.

8. The display device according to claim 2, wherein the light beam control part operates

in the first display mode, in manner to allow light beams from the single image or light beams toward the single image to pass therethrough, and

in the second display mode, in a manner to regulate light beams from the respective images displayed on the display part or light beams toward the respective images in a corresponding angular direction.

9. The display device according to claim 1, wherein

the light beam control part is a barrier part that allows light to pass therethrough or blocks the same, and

the barrier part includes a plurality of liquid crystal barriers of a first series and a plurality of liquid crystal barriers of a second series which are switchable between an open state and a closed state.

10. The display device according to claim 9, wherein

the plurality of liquid crystal barriers of the first series and the plurality of the liquid crystal barriers of the second series get into a transmissive state in the first display mode, and

the plurality of liquid crystal barriers of the first series get into the transmissive state and the plurality of liquid crystal barriers of the second series get into a blocking state in the second display mode.

11. The display device according to claim 10, wherein the plurality of liquid crystal barriers of the first series and the plurality of liquid crystal barriers of the second series extend in a predetermined direction.

12. The display device according to claim 11, wherein a width of the liquid crystal barriers of the first series is smaller than the first horizontal pixel width.

13. The display device according to claim 1, wherein

the light beam control part is a barrier part that allows light to pass therethrough or blocks the same, and

the barrier part has a plurality of fixed openings.

14. The display device according to claim 1, wherein the light beam control part has a plurality of variable lenses capable of changing a refraction index.

15. The display device according to claim 1, wherein the light beam control part has a plurality of fixed lenses.

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

a back light, wherein

the display part is a liquid crystal display part, and

the liquid crystal display part is disposed between the back light and the barrier part.

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

a back light, wherein

the display part is a liquid crystal display part, and

the barrier part is disposed between the back light and the liquid crystal display part.

18. A display panel, comprising:

a pixel of a first series having a first horizontal pixel width; and

a pixel of a second series having a second horizontal pixel width smaller than the first horizontal pixel width, wherein

the pixels of the first series and the pixels of the second series are arrayed alternately in each of a horizontal direction and a vertical direction.

19. An electronic apparatus, comprising:

a display unit; and

a control unit that performs operation control by using the display unit, wherein

the display unit includes

a display part in which a pixel of a first series having a first horizontal pixel width and a pixel of a second series having a second horizontal pixel width smaller than the first horizontal pixel width are arrayed alternately in each of a horizontal direction and a vertical direction; and

a light beam control part that controls a light beam from the display part or a light beam toward the display part.
