Abstract:
Disclosed are an optical fingerprint identification device and a display panel including the same. The optical fingerprint identification device includes a light emitting structure and a photosensitive sensor. The light emitting structure includes a transparent first electrode, an opaque second electrode, an electroluminescent layer between the first electrode and the second electrode, and a through hole penetrating the first electrode, the electroluminescent layer and the second electrode. The photosensitive sensor is disposed on a side of the second electrode facing away from the electroluminescent layer, and is configured to receive light rays transmitted through the through hole and acquire fingerprint information according to the received light rays.
