Claim 0:
1. A display substrate, comprising a plurality of first color sub-pixel blocks, a plurality of second color sub-pixel blocks, and a plurality of third color sub-pixel blocks,
wherein the display substrate comprises a plurality of first virtual rectangles;
one first color sub-pixel block, one second color sub-pixel block, and one third color sub-pixel block are provided in each first virtual rectangle;
the first virtual rectangle comprises a first edge and a second edge perpendicular to the first edge, both the first edge and the second edge have a non-zero included angle with a first direction, and the first direction is a row direction or a column direction;
in a direction parallel to at least one selected from a group consisting of the second edge, the row direction, and the column direction, a minimum distance between two adjacent second color sub-pixel blocks is smaller than a minimum distance between two adjacent first color sub-pixel blocks, and a minimum distance between two adjacent third color sub-pixel blocks is smaller than the minimum distance between the two adjacent first color sub-pixel blocks; and
a maximum size of the first color sub-pixel block in a direction parallel to the second edge is greater than a maximum size of the first color sub-pixel block in the first direction;
the display substrate further comprises a plurality of second virtual rectangles, a plurality of third virtual rectangles, and a plurality of fourth virtual rectangles;
one first virtual rectangle, one second virtual rectangle, one third virtual rectangle, and one fourth virtual rectangle form a 2*2 matrix in an edge-sharing manner to form a minimum repeating region;
the second virtual rectangle shares the first edge with the first virtual rectangle, and is mirror-symmetrical with the first virtual rectangle with respect to the first edge;
the first virtual rectangle coincides with the third virtual rectangle by shifting a distance of a length of a diagonal line of the first virtual rectangle along the diagonal line, and the third virtual rectangle is adjacent to the second virtual rectangle;
the third virtual rectangle comprises a third edge, the fourth virtual rectangle shares the third edge with the third virtual rectangle, and is mirror-symmetrical with the third virtual rectangle with respect to the third edge, and the third edge and the first edge are in a same straight line;
the first color sub-pixel block comprises a first color light emitting layer, the second color sub-pixel block comprises a second color light emitting layer, and the third color sub-pixel block comprises a third color light emitting layer;
in a same minimum repeating region, the first color light emitting layer of the first color sub-pixel block of the third virtual rectangle and the first color light emitting layer of the first color sub-pixel block of the fourth virtual rectangle are formed by sharing a same single color pattern region;
in two adjacent minimum repeating regions in a direction perpendicular to the first edge, the two adjacent minimum repeating regions comprise a first minimum repeating region and a second minimum repeating region, and the first color light emitting layer of the first color sub-pixel block of the first virtual rectangle in the first minimum repeating region and the first color light emitting layer of the first color sub-pixel block of the second virtual rectangle in the second minimum repeating region are formed by sharing a same single color pattern region;
in the same minimum repeating region, an area of the first color light emitting layer of the first color sub-pixel block of the third virtual rectangle and the first color light emitting layer of the first color sub-pixel block of the fourth virtual rectangle formed by sharing the same single color pattern region is larger than a sum of an area of the first color pixel electrode of the first color sub-pixel block of the third virtual rectangle and an area of the first color pixel electrode of the first color sub-pixel block of the fourth virtual rectangle; and
an area of the first color light emitting layer of the first color sub-pixel block of the first virtual rectangle in the first minimum repeating region and the first color light emitting layer of the first color sub-pixel block of the second virtual rectangle in the second minimum repeating region formed by sharing the same single color pattern region is larger than a sum of an area of the first color pixel electrode of the first color sub-pixel block of the first virtual rectangle in the first minimum repeating region and an area of the first color pixel electrode of the first color sub-pixel block of the second virtual rectangle in the second minimum repeating region.
