Abstract
Disclosed are a display substrate, a display device and a detection method by using a display device. The display substrate includes at least one sub-pixel, the at least one sub-pixel includes a first region and a second region, and the at least one sub-pixel includes a light emitting element which is arranged in the first region, and a pixel circuit structure and a photosensitive structure which are arranged in the second region; the pixel circuit structure and the photosensitive structure are stacked, and the photosensitive structure is closer to a light exiting side of the display substrate than the pixel circuit structure.
