1. A display substrate, comprising:
a first display sub-region, the first display sub-region comprising a plurality of first repeating regions, at least one first repeating region of the plurality of first repeating regions comprising a first pixel unit and a second pixel unit disposed adjacently, the first pixel unit comprising a first sub-pixel and a second sub-pixel, the second pixel unit comprising the second sub-pixel and a third sub-pixel; and
a second display sub-region located at at least one side of the first display sub-region, the second display sub-region comprising a plurality of second repeating regions, at least one second repeating region of the plurality of second repeating regions comprising a third pixel unit and a first transparent pixel, the third pixel unit comprising the first sub-pixel, the second sub-pixel and the third sub-pixel, wherein the first transparent pixel is not provided with a light emitting functional layer and allows ambient light to transmit,
wherein a pixel density of the second display sub-region is less than a pixel density of the first display sub-region, and a light transmittance of ambient light of the second display sub-region is greater than a light transmittance of ambient light of the first display sub-region,
wherein the at least one second repeating region is configured to be driven in a manner in which no sub-pixel is borrowed, and in the third pixel unit, the first sub-pixel and the second sub-pixel are arranged along an extending direction of the third sub-pixel, and
wherein in each of the at least one second repeating region, along a direction perpendicular to the extending direction of the third sub-pixel, the second sub-pixel and the first sub-pixel of the third pixel unit are located between the first transparent pixel and the third sub-pixel of the third pixel unit.
