Pixel array and display apparatus

A pixel array, comprising a plurality of first sub-pixels having a first color, a plurality of second sub-pixels having a second color, and a plurality of third sub-pixels having a third color;

• wherein
• the plurality of first sub-pixels and the plurality of third sub-pixels are alternately arranged in a first direction to form a plurality of first sub-pixel rows;
• the plurality of second sub-pixels are arranged in the first direction to form a plurality of second sub-pixel rows;
• the plurality of first sub-pixel rows and the plurality of second sub-pixel rows are alternately arranged in a second direction;
• and the plurality of first sub-pixels and the plurality of third sub-pixels are alternately arranged in the second direction to form a plurality of first sub-pixel columns;
• the plurality of second sub-pixels are arranged in the second direction to form a plurality of second sub-pixel columns;
• the plurality of first sub-pixel columns and the plurality of second sub-pixel columns are alternately arranged in the first direction;
• the second direction is different from the first direction, and
• wherein at least a portion of each of at least one first sub-pixel of the plurality of first sub-pixels comprises an inward indentation, at least a portion of each of at least one second sub-pixel of the plurality of second sub-pixels comprises an inward indentation, and each of at least one of the plurality of third sub-pixels adjacent to the at least one second sub-pixel comprises an outward protrusion corresponding to the inward indentation of the at least one second sub-pixel;
• wherein lines, sequentially connecting centers of two first sub-pixels and centers of two third sub-pixels in two adjacent first sub-pixel rows of the plurality of first sub-pixel rows and two adjacent first sub-pixel columns of the plurality of first sub-pixel columns, constitute a first virtual square;
• one of the plurality of second sub-pixels is at a center of the first virtual square;
• and
• the centers of the two first sub-pixels and the centers of the two third sub-pixels are at four vertexes of the first virtual square, respectively;
• wherein the at least one second sub-pixel each comprises a first side and a second side opposite to each other, which are respectively close to two adjacent third sub-pixels, the first side and the second side are symmetrically arranged about a line connecting a center of the second sub-pixel and the centers of the two adjacent third sub-pixels in the first virtual square, and this line passes through centers of the first side and the second side;
• and
• wherein the centers of the first side and the second side are on the line connecting the center of the second sub-pixel and the centers of the two adjacent third sub-pixels in the first virtual square and closer to the center of the second sub-pixel in the first virtual square than points, other than the centers of the first side and the second side, of the first side and the second side.
