Abstract
A display substrate includes a substrate, and the display substrate includes a first display region with a greatest light transmittance, a second display region, and a third display region on the substrate, the third display region is contiguous to the first and second display regions. A plurality of first sub-pixels are disposed in the first display region, a plurality of second sub-pixels are disposed in the second display region, a plurality of third sub-pixels are disposed in the third display region, and a density of the second sub-pixels is the greatest. A pixel circuit for the first sub-pixels is disposed in the third display region, a first electrode of the first sub-pixel is electrically connected to a corresponding pixel circuit via a wiring, the wiring includes a first segment of transparent conductive material disposed in the first display region and a second segment disposed in the third display region.
