1. A display substrate, comprising:
a plurality of first sub-pixels;
a plurality of second sub-pixels; and
a plurality of third sub-pixels;
wherein:
the plurality of first sub-pixels and the plurality of third sub-pixels are alternated in a first direction and a second direction so as to form a first type of rows along the first direction and a first type of columns along the second direction;
the plurality of second sub-pixels form a second type of rows along the first direction and a second type of columns along the second direction, the first type of rows and the second type of rows are alternated in the second direction, and the first type of columns and the second type of columns are alternated in the first direction;
in at least one of the first type of rows, a connection line between a center of a first sub-pixel and a center of a third sub-pixel adjacent to the first sub-pixel is not parallel to the first direction, a connection line between centers of first sub-pixels adjacent to each other is parallel to the first direction, and a connection line between centers of third sub-pixels adjacent to each other is parallel to the first direction; and
in at least one of the second type of rows, a connection line between centers of second sub-pixels adjacent to each other is parallel to the first direction;
in the at least one of the first type of rows, for a first sub-pixel and a third sub-pixel adjacent to each other, the first sub-pixel has a first vertex closest to the third sub-pixel, the third sub-pixel has a second vertex closest to the first sub-pixel, and a connection line between the first vertex and the second vertex is inclined with respect to the first direction; and
in the at least one of the first type of rows, the connection line between the center of the first sub-pixel and the center of the third sub-pixel adjacent to the first sub-pixel is inclined with respect to the connection line between the first vertex and the second vertex.
