1. A display panel, comprising:
a display module, comprising a fingerprint recognition component;
a packaging cover plate, located on a light emergent side of the display module; and
a plurality of light path adjustment devices, located between the packaging cover plate and the fingerprint recognition component;
wherein each of the light path adjustment devices comprises:
an optical fiber structure; and
a convex lens structure disposed opposite to the optical fiber structure and on a side, facing away from the packaging cover plate, of the optical fiber structure;
wherein the light path adjustment devices are configured to adjust incident light reflected by a finger, so as to reduce an angle of divergence of light entering the fingerprint recognition component; and
a center of a light outlet of the optical fiber structure overlaps with a focal point of the convex lens structure.
