Abstract

There is provided an apparatus configured to control a display section of a display unit. There is included a pixel in the display section including a plurality of sub-pixels, each of the sub-pixels including a single first electrode, a single second electrode provided along a laminating direction of the first electrode, and a light-emitting layer inserted between the first electrode and the second electrode. One or more of the plurality of sub-pixels have a plurality of window openings that include at least two or more window openings different in one or more of shape, size, and orientation from one another.

Claims (81)

the plurality of windows includes at least a first window and a second window,

a first shape of the first window is different from a second shape of the second window,

a width of the first window and a height of the first insulating layer are same,

the width of the first window is in a first direction parallel to the light-emitting layer, and

the height of the first insulating layer is in a second direction perpendicular to the light-emitting layer; and

a color filter,

wherein the plurality of windows overlaps with the color filter.

2. The display unit according to claim 1 , wherein

the first insulating layer includes a plurality of opening sections in positions corresponding to the plurality of windows,

at least one of the plurality of sub-pixels further includes a second insulating layer on the second electrode,

a first refractive index of the first insulating layer is different from a second refractive index of the second insulating layer, and

the first electrode, the light-emitting layer, the second electrode, and the second insulating layer are laminated on a bottom of the plurality of opening sections.

3. The display unit according to claim 1 , wherein a first arrangement pattern of the plurality of windows is same in each sub-pixel of the plurality of sub-pixels.

4. The display unit according to claim 3 , wherein arrangement patterns of mutually-corresponding sub-pixels in adjacent pixels of the plurality of pixels are the same as each other.

5. The display unit according to claim 3 , further comprising a second pixel of the plurality of pixels, wherein

the second pixel is adjacent to the first pixel, and

the first arrangement pattern of the plurality of windows of a first sub-pixel in the first pixel is different from a second arrangement pattern of a plurality of windows of a mutually-corresponding sub-pixel in the second pixel.

6. The display unit according to claim 1 , wherein an arrangement pattern of the plurality of windows is different in each sub-pixel of the plurality of sub-pixels.

7. The display unit according to claim 1 , wherein

the plurality of sub-pixels includes a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel,

the first sub-pixel, the second sub-pixel, and the third sub-pixel are configured to emit basic color light, and

the fourth sub-pixel is configured to emit non-basic color light.

8. The display unit according to claim 7 , wherein the plurality of windows in the fourth sub-pixel is smaller in number than the plurality of windows in the first sub-pixel, the second sub-pixel, and the third sub-pixel.

9. The display unit according to claim 1 , wherein the plurality of sub-pixels includes a first sub-pixel, a second sub-pixel, and a third sub-pixel each of which is configured to emit basic color light.

10. The display unit according to claim 1 , wherein

the first window is adjacent to the second window, and

the first window is different from the second window in at least one of a size or an orientation.

11. The display unit according to claim 1 , wherein an arrangement pattern of the plurality of windows is based on a Voronoi diagram.

12. The display unit according to claim 1 , wherein the plurality of windows is in an orderly arrangement pattern without periodicity.

13. The display unit according to claim 12 , wherein the orderly arrangement pattern is based on a Penrose tiling.

16. The display unit according to claim 12 , wherein the orderly arrangement pattern is based on an atomic arrangement of a paracrystal.

17. The display unit according to claim 1 , wherein

a first size of the first window is different from a second size of the second window,

a first orientation of the first window is different from a second orientation of the second window, and

the plurality of windows corresponds to light emission regions of each of the plurality of sub-pixels.

18. The display unit according to claim 1 , wherein a luminance of the display unit and a viewing angle of the display unit are based on the width of the first window and the height of the first insulating layer, respectively.

19. An electronic apparatus, comprising:

a display unit; and

a control section configured to control the display unit,

wherein the display unit comprises:

a pixel including a plurality of sub-pixels,

wherein each of the plurality of sub-pixels includes:
