1. A display substrate, comprising:
a base substrate comprising a first display region and a second display region, wherein the first display region at least partially surrounds the second display region, and the first display region comprises: a first sub-display region and a second sub-display region located on opposite sides of the second display region along a first direction, and a third sub-display region located on at least one side of the second display region along a second direction, wherein the first direction intersects the second direction;
multiple pixel circuits and multiple first light emitting elements located in the first display region; wherein the multiple pixel circuits comprise multiple first pixel circuits and multiple second pixel circuits, the multiple second pixel circuits are distributed among the multiple first pixel circuits, and at least one pixel circuit of the multiple first pixel circuits is connected with at least one light emitting element of the multiple first light emitting elements;
at least one first data line located in the first display region; wherein the first data line comprises a first sub-data line, a second sub-data line, and a third sub-data line, the third sub-data line is connected with the first sub-data line and the second sub-data line; and
the first sub-data line is located in the first sub-display region and is connected with a pixel circuit of the first sub-display region, the second sub-data line is located in the second sub-display region and is connected with a pixel circuit of the second sub-display region, and the third sub-data line is located in the third sub-display region and is connected with at least one second pixel circuit of the third sub-display region,
further comprising:
multiple second light emitting elements located in the second display region; and
at least one pixel circuit of the multiple second pixel circuits connected with at least one light emitting element of the multiple second light emitting elements through a conductive line.
