Pixel arrangement of color display panel

A pixel arrangement of color display panel, comprising:

• a plurality of first sub-pixels, configured to provide a first color light, wherein the first sub-pixel has a first length in a first direction;
• a plurality of second sub-pixels, configured to provide a second color light, wherein the second sub-pixel has a second length in the first direction;
• a plurality of third sub-pixels, configured to provide a third color light, wherein the third sub-pixel has a third length in the first direction;
• and
• a plurality of fourth sub-pixels configured to provide a fourth light, wherein the fourth sub-pixel has a fourth length in the first direction, the first length is substantially equal to the fourth length, the second length is substantially equal to the third length, and the second length is greater than the first length, wherein
• a portion of the first sub-pixels and a portion of the fourth sub-pixels are arranged along the first direction and form a plurality of first sub-pixel columns, and the first sub-pixels and the fourth sub-pixels of the first sub-pixel column are repeatedly arranged in a sequence of the first sub-pixel, the fourth sub-pixel and the first sub-pixel in the first direction,
• the other portion of the first sub-pixels and the other portion of the fourth sub-pixels are arranged along the first direction and form a plurality of fourth sub-pixel columns, and the first sub-pixels and the fourth sub-pixels of the fourth sub-pixel column are repeatedly arranged in a sequence of the first sub-pixel, the fourth sub-pixel and the first sub-pixel in the first direction, and any one of the first sub-pixels of the first sub-pixel column partially overlaps one of the first sub-pixels and one of the fourth sub-pixels of the fourth sub-pixel column in a second direction perpendicular to the first direction,
• a portion of the second sub-pixels and a portion of the third sub-pixels are arranged along the first direction and form a plurality of second sub-pixel columns, and the second sub-pixels and the third sub-pixels of the second sub-pixel column are repeatedly arranged in a sequence of the second sub-pixel and the third sub-pixel in the first direction,
• the other portion of the second sub-pixels and the other portion of the third sub-pixels are arranged along the first direction and form a plurality of third sub-pixel columns, and the second sub-pixels and the third sub-pixels of the third sub-pixel column are repeatedly arranged in a sequence of the third sub-pixel and the second sub-pixel in the first direction, and
• wherein the first sub-pixel columns, the second sub-pixel columns, the third sub-pixel columns and the fourth sub-pixel columns are repeatedly arranged in a sequence of the second sub-pixel column, the first sub-pixel column, the third sub-pixel column and the fourth sub-pixel column in the second direction.
