1. A display substrate, comprising:
a base substrate, which comprises a display region and a driving region arranged on at least one side of the display region;
a first electrode layer disposed in the display region;
a signal output part disposed in the driving region, the first electrode layer is electrically coupled to the signal output part, and the first electrode layer comprises a plurality of electrode regions each having a same area; and
a plurality of auxiliary electrodes, which are in one-to-one correspondence with the plurality of electrode regions and configured to be coupled in parallel with the first electrode layer, wherein a resistance of each auxiliary electrode is inversely correlated with a minimum distance from the electrode region corresponding to said each auxiliary electrode to the signal output part, wherein
each auxiliary electrode comprises at least one conductive part having a resistance inversely correlated with a minimum distance from the electrode region corresponding to the conductive part to the signal output part, and conductive parts coupled in parallel to the first electrode layer are uniformly distributed,
a pixel defining layer is further disposed in the display region, the pixel defining layer is located between the base substrate and the first electrode layer;
a first groove is provided on a side of the pixel defining layer away from the base substrate, the first electrode layer covering outer sidewalls, inner sidewalls and a bottom surface of the first groove; and
the conductive part is located in the first groove and on a side of the first electrode layer away from the base substrate, and is in contact with portions of the first electrode layer on the inner sidewalls and the bottom surface of the first groove.
