Abstract

There is provided a display device including a pixel array unit in which a plurality of pixels are arrayed in a matrix shape. A predetermined amount of light emission variation is added to a light emission state of each pixel and a cycle of the light emission state of the pixel array unit in the case of the addition is shorter than the cycle of a light emission state of the pixel array unit before the predetermined amount of light emission variation is added.

Claims (32)

1. A display device comprising:

a pixel array unit in which a plurality of pixels are arrayed in a matrix shape,

wherein a predetermined amount of light emission variation is configured to be added to a light emission state of each pixel, and a state of variation of a light emission state of the pixel array unit when the variation is added corresponds to at least any one of

(1) a state in which a cycle of the light emission state is shorter than a cycle of the light emission state of the pixel array unit before the predetermined amount of light emission variation is added, and

(2) a state in which the variation of the light emission state is greater than variation of the light emission state of the pixel array unit before the predetermined amount of light emission variation is added, and

wherein the relation of a spatial frequency and a contrast of the variation of the light emission state of the pixel array unit is set to be in the range in which it is not possible to recognize fringe patterns.

2. The display device according to claim 1 , wherein the predetermined amount of light emission variation is configured to be added to the light emission state of each pixel, and the cycle of the variation of the light emission state of the pixel array unit in the case of the addition is shorter than the cycle of the light emission state of the pixel array unit before the predetermined amount of light emission variation is added.

3. The display device according to claim 1 , wherein the predetermined amount of light emission variation is configured to be added to the light emission state of each pixel, and the variation of the light emission state of the pixel array unit in the case of the addition is greater than the variation of the light emission state of the pixel array unit before the predetermined amount of light emission variation is added.

4. The display device according to claim 1 , wherein the addition of the light emission variation is made by adjusting an inter-drain-source current of a driving transistor.

5. The display device according to claim 4 , wherein the adjustment of the inter-drain-source current of the driving transistor is made by changing a channel width.

6. The display device according to claim 4 , wherein the adjustment of the inter-drain-source current of the driving transistor is made by adjusting radiation energy of an excimer laser in a manufacturing process of the driving transistor.

7. The display device according to claim 1 , wherein the addition of the light emission variation is made by adjusting a pixel width.

8. The display device according to claim 1 , wherein the addition of the light emission variation is made by adjusting a transmittance of a color filter.

9. The display device according to claim 1 , wherein the addition of the light emission variation is made by adjusting a signal line voltage.

10. An electronic apparatus comprising: a display device according to claim 1 , wherein the display device is configured to display a video signal input from outside or a video signal generated in the inside.

11. An electronic apparatus comprising:

a display device,

wherein the display device includes a pixel array unit in which a plurality of pixels are arrayed in a matrix shape, and

wherein a predetermined amount of light emission variation is added to a light emission state of each pixel, and a cycle of the light emission state of the pixel array unit in the case of the addition is shorter than the cycle of the light emission state of the pixel array unit before the predetermined amount of light emission variation is added.

12. A display device comprising:

a pixel array unit in which a plurality of pixels are arrayed in a matrix shape,

wherein a predetermined amount of light emission variation is configured to be added to a light emission state of each pixel, and

wherein the relation of a spatial frequency and a contrast of variation of the light emission state of the pixel array unit is set to be in the range in which it is not possible to recognize a fringe pattern.

13. The display device according to claim 12 , wherein the predetermined amount of light emission variation is added to each of pixels in each row of the pixel array unit by changing at least one factor among:

(1) a degree of movement or a channel width of a transistor configured to drive the pixel;

(2) a pixel width of the pixel;

(3) a transmittance of a color filter corresponding to the pixel; and

(4) a reference value of a signal voltage supplied to the pixel.

14. The display device according to claim 13 , wherein the predetermined amount of light emission variation is added to each of the pixels in each row of the pixel array unit by changing the degree of movement or the channel width of the transistor configured to drive the pixel.

15. The display device according to claim 13 , wherein the predetermined amount of light emission variation is added to each of the pixels in each row of the pixel array unit by changing the pixel width of the pixel.

16. The display device according to claim 13 , wherein the predetermined amount of light emission variation is added to each of the pixels in each row of the pixel array unit by changing the transmittance of the color filter corresponding to the pixel.

17. The display according to claim 13 , wherein the predetermined amount of light emission variation is added to each of the pixels in each row of the pixel array unit by changing the reference value of the signal voltage supplied to the pixel.
