Abstract
An OLED display panel and an under-screen optical fingerprint recognition method are provided. In the OLED display panel, light sensitive units for optical fingerprint recognition are assembled in an OLED module functional layer and located on a same film layer where an anode of an organic electroluminescence device is located on, and located at gaps between the anodes. Such a structure reduces a path for light propagation, increases intensity of light received by the light sensitive units, and improves accuracy and efficiency in fingerprint recognition.
