Abstract

A display panel, a display device and a method for pixel arrangement, which can improve picture quality. The display panel includes a plurality of sub-pixels arranged in an array, and the sub-pixels arranged in a first direction are arranged in one of following modes: a first mode of sub-pixel arrangement, in which a first sub-pixel (A) or a third sub-pixel (C) is inserted between every two second sub-pixels (B); and a second mode of sub-pixel arrangement, in which the first sub-pixel (A) and the third sub-pixel (C) are inserted between every two second sub-pixels (B).

First claim

1 . A display panel comprising a plurality of sub-pixels arranged in an array, wherein the sub-pixels arranged in a first direction are arranged in one of following modes:
a first mode of sub-pixel arrangement, in which a first sub-pixel or a third sub-pixel is inserted between every two second sub-pixels; and a second mode of sub-pixel arrangement, in which the first sub-pixel and the third sub-pixel are inserted between every two second sub-pixels.

2 . The display panel of claim 1 , wherein, in the second mode of sub-pixel arrangement, sub-pixels are arranged in at least one of a sequence of the second sub-pixel, the first sub-pixel and the third sub-pixel and a sequence of the second sub-pixel, the third sub-pixel and the first sub- pixel.

3 . The display panel of claim 1 , wherein the first mode of sub-pixel arrangement and the second mode of sub-pixel arrangement are deployed alternately in a second direction.

4 . The display panel of claim 3 , wherein the first direction is one of a row direction and a column direction while the second direction is the other of the row direction and the column direction.

5 . The display panel of claim 1 , wherein the second sub-pixel is a green sub-pixel, the first sub-pixel is one of a red sub-pixel and a blue sub-pixel, and the third sub-pixel is the other of the red sub-pixel and the blue sub-pixel.

6 . The display panel of claim 5 , wherein compensation is performed on image data for the first sub-pixel using a first compensation parameter and mapping is performed on a compensation result of the image data for the first sub-pixel using a first mapping parameter to obtain output image data for the first sub-pixel.

7 . The display panel of claim 6 , wherein compensation is performed on image data for the third sub-pixel using a third parameter and mapping is performed on a compensation result of the image data for the third sub-pixel using a third mapping parameter to obtain output image data for the third sub-pixel.

8 . The display panel of claim 7 , wherein mapping is performed on image data for the second sub-pixel using a second mapping parameter, and a mapping result of the image data for the second sub-pixel, the compensation result of the image data for the first sub-pixel and the compensation result of the image data for the third sub-pixel are superimposed onto each other to obtain output image data for the second sub-pixel.

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

10 . A method for sub-pixel arrangement, comprising:
inserting a first sub-pixel or a third sub-pixel between every two second sub-pixels; or inserting the first sub-pixel and the third sub-pixel between every two second sub-pixels.

11 . The method for sub-pixel arrangement of claim 10 , wherein inserting the first sub-pixel and the third sub-pixel between every two second sub-pixels includes:
arranging sub-pixels in at least one of a sequence of the second sub-pixel, the first sub-pixel and the third sub-pixel and a sequence of the second sub-pixel, the third sub-pixel and the first sub-pixel.

12 . The method for sub-pixel arrangement of claim 10 , wherein a first mode of sub-pixel arrangement and a second mode of sub-pixel arrangement are deployed alternately in a second direction.

13 . The method for sub-pixel arrangement of claim 12 , wherein a first direction is one of a row direction and a column direction while the second direction is the other of the row direction and the column direction.

14 . The method for sub-pixel arrangement of claim 10 , wherein the second sub-pixel is a green sub-pixel, the first sub-pixel is one of a red sub-pixel and a blue sub-pixel, and the third sub-pixel is the other of the red sub-pixel and the blue sub-pixel.

15 . The display panel of claim 2 , wherein the second sub-pixel is a green sub-pixel, the first sub-pixel is one of a red sub-pixel and a blue sub-pixel, and the third sub-pixel is the other of the red sub-pixel and the blue sub-pixel.

16 . The display panel of claim 15 , wherein compensation is performed on image data for the first sub-pixel using a first compensation parameter and mapping is performed on a compensation result of the image data for the first sub-pixel using a first mapping parameter to obtain output image data for the first sub-pixel.

17 . The display panel of claim 16 , wherein compensation is performed on image data for the third sub-pixel using a third parameter and mapping is performed on a compensation result of the image data for the third sub-pixel using a third mapping parameter to obtain output image data for the third sub-pixel.

18 . The display panel of claim 17 , wherein mapping is performed on image data for the second sub-pixel using a second mapping parameter, and a mapping result of the image data for the second sub-pixel, the compensation result of the image data for the first sub-pixel and the compensation result of the image data for the third sub-pixel are superimposed onto each other to obtain output image data for the second sub-pixel.

19 . The display panel of claim 2 , wherein the first mode of sub-pixel arrangement and the second mode of sub-pixel arrangement are deployed alternately in a second direction.

20 . The display panel of claim 19 , wherein the first direction is one of a row direction and a column direction while the second direction is the other of the row direction and the column direction.
