1. A display substrate, comprising:
a base substrate;
a plurality of pixel units, wherein the plurality of pixel units are located on the base substrate;
a blocking structure, wherein the blocking structure surrounds the plurality of pixel units;
an auxiliary connection structure, comprising a first side surface and a second side surface which are opposite to each other, wherein the first side surface is closer to the plurality of pixel units than the second side surface;
a cathode layer, located on a side of the auxiliary connection structure away from the base substrate;
a first organic pattern, located on the side of the auxiliary connection structure away from the base substrate;
at least one first power line, located on the base substrate, wherein the at least one first power line comprises a first portion, a second portion and a first metal layer, wherein the first portion is located on a side of the blocking structure away from the plurality of pixel units and is configured to receive a power signal, the second portion is connected with the cathode layer by the auxiliary connection structure, and the second portion has a first connection position and a second connection position, the second portion is connected with the auxiliary connection structure at both the first connection position and the second connection position, and a distance between the first connection position and the blocking structure is greater than a distance between the second connection position and the blocking structure;
wherein the at least one first power line further comprises a second metal layer located on a side of the first metal layer away from the base substrate, and a side of the second metal layer away from the first metal layer is in contact with the auxiliary connection structure; or
wherein the display substrate further comprises an auxiliary metal layer located on a side of the first metal layer away from the base substrate, and a side of the auxiliary metal layer away from the first metal layer is in contact with the auxiliary connection structure.
