1. A pixel arrangement structure, comprising at least one pixel group, wherein the pixel group comprises at least one first type pixel and at least one second type pixel;
the first type pixel comprises a high grayscale sub-pixel and a first low grayscale sub-pixel, the second type pixel comprises a second low grayscale sub-pixel and a third low grayscale sub-pixel, and a grayscale value of the high grayscale sub-pixel, a grayscale value of the first low grayscale sub-pixel, a grayscale value of the second low grayscale sub-pixel, and a grayscale value of the third low grayscale sub-pixel are different;
in each of the pixel groups, a number of the first type pixels is equal to a number of the second type pixels, a number of the high grayscale sub-pixels, a number of the first low grayscale sub-pixels, a number of the second low grayscale sub-pixels, and a number of the third low grayscale sub-pixels are all equal, and the first type pixel and the second type pixel in each of the pixel groups are arranged in two rows and two columns;
wherein in each of the pixel groups, the first type pixels are arranged in one column, and the second type pixels are arranged in another column;
in a column direction of the pixel arrangement structure, in two adjacent pixel groups, the first type pixels are not arranged in a same column, and the second type pixels are not arranged in a same column.
