1. A display substrate, comprising a base having an installation area, a transition area surrounding the installation area, and a display area surrounding the transition area; the installation area, the transition area, and the display area each comprising a sub-pixel area; wherein the sub-pixel area in the transition area comprises at least a first type sub-pixel area and a second type sub-pixel area; and the sub-pixel area in the installation area comprises at least a third type sub-pixel area;
the first type sub-pixel area is provided with a pixel circuit on the base; the pixel circuit comprising a driving sub-circuit and a light-emitting device; the second type sub-pixel area is provided with the driving sub-circuit on the base; and the third type sub-pixel area is provided with the light-emitting device on the base; and
wherein the light-emitting device in the third type sub-pixel area of the installation area is coupled to the driving sub-circuit in the second type sub-pixel area of the transition area via a signal connection line; different light-emitting devices are coupled to different signal connection lines and different driving sub-circuits; and orthographic projections of at least some of the signal connection lines overlap with one another on the base.
