1. A display substrate, comprising a base substrate, and a driving circuit layer and a light-emitting device layer located on the base substrate, wherein
the display substrate comprises a light-transmitting display area and a normal display area, the normal display area surrounds at least a portion of the light-transmitting display area; the normal display area comprises a plurality of normal driving circuits and a plurality of dummy driving circuits; some of the dummy driving circuits are configured to drive light-emitting devices located in the light-transmitting display area;
the display substrate further comprises a plurality of normal data lines coupled to the normal driving circuits; wherein at least one of the normal data lines is coupled to a data signal input terminal through a data lead; an orthographic projection of at least a portion of the data lead onto the base substrate at least partially overlaps with an orthographic projection of the dummy driving circuits onto the base substrate;
the data lead comprises a first line segment and a second line segment coupled to each other, the first line segment comprises at least a portion extending along a first direction, the second line segment comprises at least a portion extending along a second direction, and the first direction intersects the second direction;
the plurality of dummy driving circuits is divided into a plurality of columns of dummy driving circuits, and each column of dummy driving circuits comprises a plurality of dummy driving circuits arranged along the second direction; and
the first line segment is coupled to the normal data line, and the second line segment is coupled to the data signal input terminal; an orthographic projection of the second line segment onto the base substrate at least partially overlaps with an orthographic projection of at least some of dummy driving circuits comprised in a corresponding column of dummy driving circuits onto the base substrate.
