Abstract

A display panel and a fabrication method of the display panel are provided. The display panel includes a plurality of pixel rows, which includes first pixel rows and second pixel rows that are alternately arranged and is extended along a first direction. A first pixel row includes a plurality of first units, and a first unit includes two first sub-pixels arranged along a second direction with a same color. First sub-pixels in adjacent first units have different colors. The second direction intersects with and is non-perpendicular to the first direction. A second pixel row includes a plurality of second units, and a second unit includes two second sub-pixels arranged along the second direction with a same color. The first pixel rows and the second pixel rows are alternately arranged in a third direction perpendicular to the first direction. The first sub-pixels have a color different from the second sub-pixels.

Claims (37)

1. A display panel, comprising:

a plurality of pixel rows extended along a first direction, wherein the plurality of pixel rows includes first pixel rows and second pixel rows that are alternately arranged, wherein:

a first pixel row includes a plurality of first units, each of the plurality of first units includes two first sub-pixels with a same color, the two first sub-pixels in each of the plurality of first units are arranged along a second direction, first sub-pixels in adjacent first units have different colors, and the second direction intersects with and is non-perpendicular to the first direction,

a second pixel row includes a plurality of second units, each of the plurality of second units includes two second sub-pixels with a same color, the two second sub-pixels in each of the plurality of second units are arranged along the second direction, and in the second direction, a distance between each two adjacent sub-pixels with different colors is greater than a distance between each two adjacent sub-pixels with a same color,

a number of the first units in the first pixel row equals a number of the second units in the second pixel row,

the first pixel rows and the second pixel rows are alternately arranged in a third direction perpendicular to the first direction, and

each of the two first sub-pixels has a color different from the second sub-pixels.

2. The display panel according to claim 1 , wherein:

each second sub-pixel and two adjacent first sub-pixels with different colors form an equivalent pixel.

3. The display panel according to claim 2 , wherein:

in a same one equivalent pixel, the two adjacent first sub-pixels with different colors include a first of the two adjacent first sub-pixels with a first color and a second of the two adjacent first sub-pixels with a second color, respectively, and

the first sub-pixel with the first color is adjacent to the first sub-pixel with the second color in the first direction.

4. The display panel according to claim 2 , wherein:

in a same one equivalent pixel, the two adjacent first sub-pixels with different colors include a first of the two adjacent first sub-pixels with a first color and a second of the two adjacent first sub-pixels with a second color, respectively, and

the second sub-pixel is adjacent to the first of the two adjacent first sub-pixels with the first color in the third direction, and is adjacent to the second of the two adjacent first sub-pixels with the second color in the second direction.

5. The display panel according to claim 1 , wherein:

in the second direction, a spacing between adjacent first sub-pixel and second sub-pixel is a, and a spacing between adjacent two first sub-pixels or between adjacent two second sub-pixels is b, wherein a>b.

6. The display panel according to claim 5 , wherein:

21 μm≤a≤30 μm, and

10 μm≤b≤19 μm.

7. The display panel according to claim 1 , wherein:

the first sub-pixel has an area larger than the second sub-pixel.

8. The display panel according to claim 7 , wherein:

the first sub-pixel has a same shape as the second sub-pixel.

9. The display panel according to claim 1 , wherein:

a first color of each of the first sub-pixels is blue or green, and a second color of each of the second sub-pixels is red; or

the first color of each of the first sub-pixels is blue or red, and the second color of each of the second sub-pixels is green; or

the first color of each of the first sub-pixels is green or red, and the second color of each of the second sub-pixels is blue.

10. The display panel according to claim 1 , wherein:

a shape of the first sub-pixel includes one of a rectangle, a diamond, a square, a hexagon, an octagon, a triangle, a circle, and an ellipse; and

a shape of the second sub-pixel includes one of a rectangle, a diamond, a square, a hexagon, an octagon, a triangle, a circle, and an ellipse.

11. The display panel according to claim 1 , wherein:

an angle between the second direction and the first direction is in a range of approximately 30°-60°.

12. The display panel according to claim 1 , wherein:

the display panel is an organic light-emitting display panel.

13. The display panel according to claim 1 , wherein:

the first units and the second units are alternately arranged in the second direction.
