1. A display substrate, wherein
a display region of the display substrate comprises a first display region and a second display region;
a light transmittance of the first display region is greater than that of the second display region;
the display region is provided with a plurality of pixel groups, each pixel group comprises a plurality of sub-pixels arranged along a first direction, the plurality of pixel groups are arranged in a second direction;
the plurality of pixel groups comprise a plurality of first-type pixel groups and a plurality of second-type pixel groups;
the first display region is provided with a plurality of first sub-pixels, and the second display region is provided with a plurality of second sub-pixels;
a density of the first sub-pixels is smaller than a density of the second sub-pixels;
the first-type pixel group comprises the first sub-pixels and the second sub-pixels; the second-type pixel group comprises only the second sub-pixels;
the second sub-pixels of the first-type pixel groups are disposed in regions at two sides of the first display region in the first direction, and/or the second sub-pixels of the second-type pixel groups are disposed in regions at two sides of the first display region in the first direction;
the display region is provided with a plurality of first-type data lines, a plurality of second-type data lines, a power line, and pixel circuits corresponding to the sub-pixels in an one-to-one manner; the pixel circuits of the first sub-pixels and the second sub-pixels of each first-type pixel group are connected to a same first-type data line; the pixel circuits of the second sub-pixels of each second-type pixel group are connected to a same second-type data line; and
a first-display-region-located portion of the power line is disposed below a first-display-region-located portion of the first-type data line.
