Abstract
A display panel is provided to include a substrate; a photoelectric sensing structure on a side of the substrate; a light emitting structure on a side of the photoelectric sensing structure distal to the substrate, and light emitting elements, each of which includes: a first electrode, a light emitting layer, and a second electrode which are successively in a direction distal to the substrate; and a light path structure between the photoelectric sensing structure and the second electrode, and configured to collimate light on a side of the photoelectric sensing structure distal to the substrate and having a propagation direction towards the photoelectric sensing structure; the photoelectric sensing structure and the light emitting structure do not overlap or partially overlap in a direction perpendicular to the substrate; and the light path structure at least partially overlaps the photoelectric sensing structure in the direction. The embodiment also provides a display device.
