Abstract

The present disclosure provides a pixel structure, a display panel, and a display apparatus. The pixel structure includes a plurality of pixel cells having a first pixel cell and a first adjacent pixel cell. Each pixel cell includes a first pixel; and two second pixels and two third pixels, surrounding the first pixel. Each of the two second pixels and the two third pixels is arranged separately in a direction along a side of a virtual rectangular area, the first pixel corresponding to one portion of the virtual rectangular area. Each of the two second pixels and the two third pixels has a first portion arranged in the first pixel cell covered by a first virtual rectangular area, and a second portion arranged in the first adjacent pixel cell covered by a second virtual rectangular area.

First claim

What is claimed is:

1. A pixel structure, comprising:
a first pixel; and
side pixels including two second pixels and two third pixels, wherein:
one side of each side pixel is substantially parallel to at least one side of another side pixel;
the side pixels surround the first pixel and a virtual rectangular area containing at least a portion of the first pixel is defined;
at least two adjacent ones of the side pixels are approximately perpendicular to each other and together form a T-shaped pattern; and
a portion of at least one of the side pixels extends outside the virtual rectangular area.

2. The pixel structure of claim 1 , wherein:
the virtual rectangular area is centered by the first pixel.

3. The pixel structure of claim 2 , wherein:
the T-shaped pattern is formed with one pixel having a longitudinal axis aligned with a width center of another pixel.

4. The pixel structure of claim 1 , wherein:
the first pixel has a rectangular shape, and
a plurality of the first pixels in a plurality of the pixel structures are arrayed.

5. The pixel structure of claim 1 , wherein:
the first pixel has a square shape, and
each of the side pixels has a rectangular shape.

6. The pixel structure of claim 5 , wherein:
the side pixels have substantially equal length, and
the equal length is greater than twice a length of the first pixel.

7. The pixel structure of claim 5 , wherein:
the side pixels have substantially equal length, and
the equal length is substantially twice a length of the first pixel plus a width of the second pixel or the third pixel.

8. The pixel structure of claim 5 , wherein the first pixel and each of the side pixels have at least one chamfered corner.

9. The pixel structure of claim 5 , wherein same pixels, among the two second pixels and the two third pixels, are configured on opposite sides of the first pixel.

10. The pixel structure of claim 9 , wherein:
the two second pixels are symmetrically configured and centered by the first pixel,
the two third pixels are symmetrically configured and centered by the first pixel, and
each of the two third pixels is approximately perpendicular to an adjacent second pixel.

11. The pixel structure of claim 5 , wherein:
the two second pixels are configured in a T-shaped pattern, and
the two third pixels are configured in another T-shaped pattern.

12. The pixel structure of claim 11 , wherein different pixels, among the two second pixels and the two third pixels, are configured on opposite sides of the first pixel.

13. The pixel structure of claim 11 , wherein:
the two second pixels are configured approximately perpendicular to one another,
the two third pixels are configured approximately perpendicular to one another, and
each of the two third pixels is approximately perpendicular to an adjacent second pixel.

14. The pixel structure of claim 1 , wherein: the first pixel, the second pixel, and the third pixel are configured to emit different color lights.

15. The pixel structure of claim 14 , wherein:
the first pixel is configured to emit green light,
the second pixel is configured to emit one of red or blue light, and
the third pixel is configured to emit the other one of the red or blue light not emitted by the second pixel.

16. A display panel, comprising the pixel structure of claim 1 .

17. A display apparatus, comprising the display panel of claim 16 .

18. The pixel structure of claim 1 , wherein: a portion of the side pixels covered by the virtual rectangular area is one quarter of an area of the side pixels.
