    Abstract: The present disclosure provides a fingerprint identification panel, a fingerprint identification method and a display device. The fingerprint identification panel includes: a display panel including a substrate and a display element arranged at one side of the substrate; and a fingerprint identification module arranged at a side of the substrate away from the display element. The fingerprint identification module includes a collimation membrane and photosensitive sensors. The collimation membrane is configured to allow a collimated light beam in a reflected light beam to pass therethrough and prohibit a scattered light beam in the reflected light beam from passing therethrough. The reflected light beam is formed by a light beam emitted from the display panel and reflected by a finger. Each photosensitive sensor is configured to receive the collimated light beam and identity a fingerprint in accordance with the collimated light beam.
