Abstract
An organic light-emitting diode (OLED) display panel and a display device are provided. The OLED display panel includes a substrate, a driving circuit layer formed on a side of the substrate, a light-emitting material layer formed on a side of the driving circuit layer away from the substrate, a sensing unit formed on another side of the substrate away from the driving circuit layer and configured to receive light reflected by a fingerprint surface. In a fingerprint identifying region of the OLED display panel, the substrate includes a through hole, and the light emitted from the light-emitting material layer and reflected by the fingerprint surface travels through the through hole and arrivals the sensing unit.
