1. A display substrate, comprising: a base substrate and a plurality of pixel units arranged in an array on the base substrate; wherein the pixel unit comprises at least one sub-pixel, and the sub-pixel comprises a pixel opening area; the display substrate further comprises:
a plurality of signal lines, the signal line being arranged on the base substrate, the signal line being configured to provide a signal for a corresponding sub-pixel; and
a grid-shaped cathode layer, wherein the cathode layer comprises a plurality of first cathode patterns and a plurality of second cathode patterns, the plurality of first cathode patterns is arranged in an array, and adjacent first cathode patterns are coupled via at least one second cathode pattern; an orthographic projection of the first cathode pattern onto the base substrate covers each pixel opening area in a corresponding pixel unit; an orthographic projection of the second cathode pattern onto the base substrate at least partially overlaps with an orthographic projection of at least part of the plurality of signal lines onto the base substrate;
wherein the orthographic projection of the first cathode pattern onto the base substrate at least partially overlaps with the orthographic projection of the at least part of the plurality of signal lines onto the base substrate;
wherein the plurality of second cathode patterns comprise a plurality of first sub-patterns, and adjacent first cathode patterns arranged in a first direction are coupled via at least one first sub-pattern; and
the plurality of signal lines comprises a plurality of data lines, the data line comprises a first data portion and a second data portion alternately arranged in the first direction, an orthographic projection of the first data portion onto the base substrate at least partially overlaps with an orthographic projection of a corresponding first cathode pattern onto the base substrate, and an orthographic projection of the second data portion onto the base substrate at least partially overlaps with an orthographic projection of a corresponding first sub-pattern onto the base substrate.
