Abstract
The present disclosure relates to the field of fingerprint identification technology, and provides a fingerprint identification substrate, a fingerprint identification method and a display device. The fingerprint identification substrate includes: a base substrate; at least one point light source arranged on the base substrate and configured to emit signal light; and at least one photosensitive unit arranged at a side of the base substrate away from the point light source, and configured to receive the signal light reflected by a finger and identify a fingerprint. Each photosensitive unit includes a first photosensitive sensor and a second photosensitive sensor independent of each other, a light filtration structure is arranged at a side of the second photosensitive sensor facing the point light source and configured to merely allow light in a first direction to pass therethrough, and the first direction is perpendicular to the base substrate.
