Display panel, display device and display method

A display method applied in a display panel comprising at least a first sub pixel column, a second sub pixel column and a third sub pixel column that are sequentially arranged, wherein:

• the first sub pixel column is formed of 2N first color sub pixels, where N is a positive integer;
• the second sub pixel column is formed of 2N second color sub pixels and is offset by a predetermined pitch in a column direction with respect to the first sub pixel column;
• and the third sub pixel column is formed of alternate N third color sub pixels and N white sub pixels, wherein each of the second color sub pixels forms a pixel unit together with one white sub pixel, one third color sub pixel and two first color sub pixels adjacent to the second color sub pixel to perform display;
• wherein the first color is red, the second color is green, and the third color is blue;
• and wherein the first color sub pixel has an aspect ratio of 7:4, the second color sub pixel has an aspect ratio of 7:2, the third color sub pixel has an aspect ratio of 14:9, the white sub pixel has an aspect ratio of 7:9, and a longitudinal direction of each sub pixel is the same as that of a corresponding sub pixel column, the display method comprising:
• according to a sub pixel rendering algorithm, converting a brightness value of each sub pixel in a first virtual pixel array corresponding to an image to be displayed into a brightness value of each sub pixel in the pixel unit.
