Pixel arrangement, manufacturing method thereof, display panel, display device and mask

A set of masks for manufacturing a pixel arrangement, wherein the pixel arrangement comprises:

• a plurality of first groups of sub-pixels arranged in a first direction, each of the plurality of first groups comprising a plurality of first sub-pixels and a plurality of third sub-pixels arranged alternately;
• and
• a plurality of second groups of sub-pixels arranged in the first direction, each of the plurality of second groups comprising a plurality of third sub-pixels and a plurality of second sub-pixels arranged alternately,
• wherein the plurality of first groups and the plurality of second groups are alternately arranged in a second direction perpendicular to the first direction, and
• wherein the plurality of first groups and the plurality of second groups are arranged to form a plurality of third groups of sub-pixels arranged in the second direction and a plurality of fourth groups of sub-pixels arranged in the second direction, the plurality of third groups and the plurality of fourth groups are alternately arranged in the first direction, each of the plurality of third groups comprises a plurality of first sub-pixels and a plurality of third sub-pixels arranged alternately, and each of the plurality of fourth groups comprises a plurality of third sub-pixels and a plurality of second sub-pixels arranged alternately,
• the set of masks comprising:
• a first mask defining a plurality of first openings arranged to have a pattern corresponding to a pattern of the first sub-pixels;
• a second mask defining a plurality of second openings arranged to have a pattern corresponding to a pattern of the second sub-pixels;
• and
• a third mask defining a plurality of third openings arranged to have a pattern corresponding to a pattern of the third sub-pixels.

A pixel arrangement, comprising:

• five first sub-pixels respectively at a center and four vertices of a first imaginary rectangle;
• four second sub-pixels at respective centers of four sides of the first imaginary rectangle;
• and
• four third sub-pixels, each within respective four second imaginary rectangles, wherein each of the second imaginary rectangles is defined by a respective vertex of the four vertices of the first imaginary rectangle, centers of adjacent sides of the first imaginary rectangle, and the center of the first imaginary rectangle, the four second imaginary rectangles together forming the first imaginary rectangle.
