1. A display substrate, comprising:
a base substrate, comprising a display area and a bezel area on at least one side of the display area;
a plurality of pixel units in the display area, wherein the plurality of pixel units are arranged on the base substrate in an array in a row direction and a column direction, and each row of pixel units comprises a plurality of sub-pixels;
a plurality of scanning signal lines arranged on the base substrate and configured to provide a scanning signal to a plurality of rows of sub-pixels respectively;
a plurality of load compensation units arranged on the base substrate and located in the bezel area, wherein the plurality of load compensation units are electrically connected to at least some of the plurality of scanning signal lines respectively; and
a common electrode arranged on the base substrate, wherein at least part of the common electrode is in the display area, and the common electrode is configured to receive a common voltage signal,
wherein at least one of the plurality of load compensation units comprises at least one of a compensation capacitor and a compensation resistor;
wherein the display substrate comprises N rows of pixel units, and n rows of pixel units among the N rows of pixel units comprise different numbers of sub-pixels, wherein N is a positive integer greater than or equal to 2, and n is a positive integer greater than or equal to 2 and less than or equal to N; and
wherein the scanning signal line for each of the n rows of pixel units is electrically connected to a respective load compensation unit, a load compensation value of the load compensation unit for each row of pixel units is negatively related to the number of sub-pixels of the row of pixel units, and the load compensation value comprises at least one of a capacitance compensation value and a resistance compensation value.
