1. A display substrate having an display area, the display area including a plurality of sub-display areas; the display substrate comprising:
a base;
a plurality of columns of pixels disposed on the base and located in the display area, at least two columns of pixels in the plurality of columns of pixels being disposed in each sub-display area, and each column of pixels including at least three columns of sub-pixels;
a plurality of first power lines disposed on the base, each sub-display area being provided with at least one first power line of the plurality of first power lines, the at least one first power line being configured to provide a first power signal to all sub-pixels in the sub-display area where the at least one first power line is located; and
a plurality of second power lines disposed on the base, extension directions of the plurality of second power lines and the plurality of first power lines being the same as an arrangement direction of a plurality of sub-pixels in a column of sub-pixels; the plurality of second power lines being configured to provide a second power signal to all sub-pixels located in the display area; wherein
a plurality of columns of sub-pixels are disposed between any two adjacent power lines among the plurality of first power lines and the plurality of second power lines, and any first power line and any second power line are each arranged between a column of sub-pixels for emitting light of a first color and a column of sub-pixels for emitting light of a second color adjacent thereto.
