Abstract

A pixel arrangement including first groups of sub-pixels arranged in a first direction, each of the first groups including first sub-pixels and third sub-pixels arranged alternately, and second groups of sub-pixels arranged in the first direction, each of the second groups including third sub-pixels and second sub-pixels arranged alternately. The first groups and the second groups are alternately arranged in a second direction perpendicular to the first direction. The first groups and the second groups are arranged to form third groups of sub-pixels arranged in the second direction and fourth groups of sub-pixels arranged in the second direction. The third groups and the fourth groups are alternately arranged in the first direction. Each of the third groups includes first sub-pixels and third sub-pixels arranged alternately. Each of the fourth groups includes third sub-pixels and second sub-pixels arranged alternately.
