Claim 0:
1. A display substrate comprising:
a base substrate and a plurality of first color sub-pixels, a plurality of second color sub-pixels and a plurality of third color sub-pixels disposed on the base substrate, current efficiency of the first color sub-pixel being less than current efficiency of the second color sub-pixel;
a light emitting control signal line, extending along a first direction;
a data line, extending along a second direction, the first direction being intersected with the second direction; and
a power line, overlapping with the data line in a third direction perpendicular to the base substrate,
wherein at least one sub-pixel comprises an organic light emitting element and a pixel circuit for driving the organic light emitting element,
the organic light emitting element comprises a first electrode, a second electrode and a light emitting layer disposed between the first electrode and the second electrode; the pixel circuit comprises a driving transistor and a first light emitting control transistor, and the pixel circuit further comprises a connection structure,
in at least one second color sub-pixel, a first electrode of the first light emitting control transistor of the second color sub-pixel is electrically connected with the connection structure through a first connection hole, and the connection structure is electrically connected with the second electrode of the second color sub-pixel through a second connection hole;
in at least one third color sub-pixel, the second electrode of the third color sub-pixel does not overlap with a channel of the driving transistor controlling the organic light emitting element of the third color sub-pixel in the third direction.
