Abstract
A display substrate includes a first display region and a second display region located at at least one side of the first display region, a light transmittance of the first display region is greater than that of the second display region. The first display region is provided with first light emitting devices, the second display region is provided with first pixel driving circuits, second pixel driving circuits, and second light emitting devices. The first pixel driving circuit drives the first light emitting device, and the second pixel driving circuit drives the second light emitting device. The second display region further includes initialization signal lines respectively connected with the first pixel driving circuits and the second pixel driving circuits and apply initialization signals thereto. The first pixel driving circuit and the second pixel driving circuit are respectively connected to different initialization signal lines.
