Abstract

An organic light-emitting diode display panel and a display device are provided, including a plurality of pixel units ( 1 ), each pixel unit including at least sub-pixels of three primary colors of red, green and blue made of different organic electroluminescent materials; the pixel unit includes at least three regions, the number of the regions being equal to the number of sub-pixels in the pixel unit, and each of the regions having a same area; the blue sub-pixel is located in at least two regions, and the other sub-pixels of different primary colors are located in different regions, an area of the blue sub-pixel being greater than those of other sub-pixels of a same primary color.

First claim

1 . An organic light-emitting diode display panel, comprising a plurality of pixel units, each pixel unit including at least sub-pixels of three primary colors of red, green and blue made of different organic electroluminescent materials, wherein,
the pixel unit includes at least three regions, a number of the regions being equal to a number of sub-pixels in the pixel unit, and each of the regions having a same area; the blue sub-pixel is located in at least two regions, and the other sub-pixels of different primary colors are located in different regions, an area of the blue sub-pixel being greater than those of other sub-pixels of a same primary color.

2 . The display panel according to claim 1 , wherein, the blue sub-pixel includes a first portion and a second portion intersecting with each other; the first portion is located in a region, and at least part of the second portion and the sub-pixels of other colors are located in a same region.

3 . The display panel according to claim 2 , wherein, the first portion is a stripe-shaped structure extending along a first direction, and the second portion is a stripe-shaped structure extending along a second direction, the first direction being perpendicular to the second direction.

4 . The display panel according to claim 3 , wherein, a maximum width of the first portion along the second direction is same as those of other sub-pixels along the second direction.

5 . The display panel according to claim 3 , a maximum width of the second portion along the first direction is same as that of the first portion along the second direction.

6 . The display panel according to claim 1 , wherein, the blue sub-pixel is located in two regions, and the red sub-pixel is located in one of the two regions.

7 . The display panel according to claim 2 , wherein, the blue sub-pixel is located in two regions; and the red sub-pixel and a first portion of the blue sub-pixel are located in different regions, and the red sub-pixel and a second portion of the blue sub-pixel are located in a same region.

8 . The display panel according to claim 1 , wherein, the blue sub-pixel is located in three regions, and the red sub-pixel and the green sub-pixel are located in one of the three regions.

9 . The display panel according to claim 2 , wherein, the blue sub-pixel is located in three regions; and the red sub-pixel and a first portion of the blue sub-pixel are located in different regions, and the red sub-pixel and a second portion of the blue sub-pixel are located in a same region.

10 . The display panel according to claim 1 , wherein, an area of the green sub-pixel is greater than that of the red sub-pixel.

11 . The display panel according to claim 1 , wherein, the pixel unit further includes a white sub-pixel or a yellow sub-pixel, and an area of the white sub-pixel or the yellow sub-pixel is less than that of the red sub-pixel.

12 . A display device, comprising the display panel according to claim 1 .

13 . An organic light-emitting diode display panel, comprising a plurality of pixel units, each pixel unit including at least sub-pixels of three primary colors of red, green and blue made of different organic electroluminescent materials, wherein,
an area of the blue sub-pixel is greater than those of the red sub-pixel and the green sub-pixel.

14 . The display panel according to claim 13 , wherein, an area of the green sub-pixel is greater than that of the red sub-pixel.

15 . The display panel according to claim 13 , wherein, the pixel unit further includes a white sub-pixel or a yellow sub-pixel, and an area of the white sub-pixel or the yellow sub-pixel is less than that of the red sub-pixel.

16 . The display panel according to claim 4 , a maximum width of the second portion along the first direction is same as that of the first portion along the second direction.

17 . The display panel according to claim 2 , wherein, an area of the green sub-pixel is greater than that of the red sub-pixel.

18 . The display panel according to claim 2 , wherein, the pixel unit further includes a white sub-pixel or a yellow sub-pixel, and an area of the white sub-pixel or the yellow sub-pixel is less than that of the red sub-pixel.

19 . The display panel according to claim 6 , wherein, an area of the green sub-pixel is greater than that of the red sub-pixel.

20 . The display panel according to claim 6 , wherein, the pixel unit further includes a white sub-pixel or a yellow sub-pixel, and an area of the white sub-pixel or the yellow sub-pixel is less than that of the red sub-pixel.
