1. A display substrate, having a first display region and a second display region, a light transmittance of the first display region being greater than a light transmittance of the second display region, and comprising:
a substrate;
a plurality of first pixel units disposed in the first display region, each of the plurality of first pixel units comprising first OLED pixels of n colors, the first OLED pixels being disposed on the substrate, each of the first OLED pixels comprising at least two first sub-pixels arranged at intervals in a first direction,
wherein each of the first sub-pixels comprises:
a first electrode block;
a first light-emitting structure block, disposed on the first electrode block; and
a second electrode, disposed on the first light-emitting structure block; and
a plurality of second pixel units, disposed in the second display region, each of the second pixel units comprising second OLED pixels of n colors, and the second OLED pixels being disposed on the substrate;
wherein adjacent first sub-pixels of different first OLED pixels are arranged at intervals in a second direction, adjacent first electrode blocks of each of the plurality of first OLED pixels are electrically connected; and
a ratio of a first size of the first pixel unit in the first direction to a second size of the first pixel unit in the second direction is substantially same as a ratio of a first size of the second pixel unit in the first direction to a second size of the second pixel unit in the second direction, wherein the first direction intersects the second direction, and n is a natural number greater than or equal to 3.
