1. A display substrate, comprising: a substrate, and a power source layer, a conductive layer, and a cathode layer which are sequentially stacked on the substrate in a direction away from the substrate, wherein
the conductive layer comprises first conductive patterns and second conductive patterns insulated from each other, the first conductive patterns are coupled to the power source layer, and the second conductive patterns are coupled to the cathode layer;
wherein the conductive layer comprises a plurality of first conductive patterns independent from each other; the plurality of first conductive patterns are respectively coupled with the power layer; and the second conductive patterns are in a grid form;
wherein the plurality of first conductive patterns are divided into at least one row of first conductive patterns, each row of first conductive patterns comprise at least one first conductive pattern arranged in a first direction, the first conductive pattern comprise at least a portion extending in a second direction, and the second direction intersects the first direction.
