1. A display substrate, comprising a light-transmitting region and a normal display region surrounding the light-transmitting region,
wherein the light-transmitting region comprises a plurality of rows of effective sub-pixel sets and a plurality of main light-transmitting regions, each row of the plurality of rows of effective sub-pixel sets comprises a plurality of effective sub-pixel sets, each of the plurality of effective sub-pixel sets comprises a plurality of effective sub-pixels, any two adjacent effective sub-pixel sets in a same row are spaced apart from each other by one main light-transmitting region, the main light-transmitting region comprises at least two sub-light-transmitting regions arranged along a column direction, and
wherein at least two sub-light-transmitting regions arranged along a row direction have different widths; and/or at least two sub-light-transmitting regions of a same main sub-light-transmitting region have different widths,
in the light-transmitting region, each effective sub-pixel comprises a pixel driving circuit for driving the effective sub-pixel to emit light; in the light-transmitting region, at least one of the plurality of signal lines connected to the effective sub-pixel comprises a portion extending along a row direction or a column direction in a region where the effective sub-pixel is located and a bent portion bending along an edge of the main light-transmitting region adjacent to the effective sub-pixel.
