摘要： A display substrate and a display apparatus. The display substrate comprises a first display area and a second display area located on at least one side of the first display area, and the light transmittance of the first display area is greater than that of the second display area. The first display area is provided with a plurality of first light-emitting devices, the second display area is provided with a plurality of first pixel driving circuits and a plurality of second pixel driving circuits, and the second display area is further provided with a plurality of second light-emitting devices. The first pixel driving circuits are configured to drive the first light-emitting devices, and the second pixel driving circuits are configured to drive the second light-emitting devices. The second display area further comprises a plurality of initialization signal lines which are respectively connected to the plurality of first pixel driving circuits and the plurality of second pixel driving circuits and are configured to apply initialization signals to the first light-emitting devices and the second light-emitting devices. The first pixel driving circuits and the second pixel driving circuits are respectively connected to different initialization signal lines. Hence, a display difference between the first display area and the second display area can be improved.

摘要： Provided are a display substrate and a display device. The display substrate includes a base substrate, and a driving circuit layer and a light-emitting device layer on the base substrate. The display substrate includes 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 includes multiple normal driving circuits and multiple dummy driving circuits; some dummy driving circuit are used for driving light-emitting devices located in the light-transmitting display area. The display substrate further includes multiple normal data lines coupled to the normal driving circuits; at least one normal data line is coupled to a data signal input terminal through a data lead; an orthographic projection of the data lead onto the base substrate at least partially overlaps an orthographic projection of the dummy driving circuit onto the base substrate.
