Abstract

A display panel and a display apparatus are provided. The display panel comprises an array substrate, a plurality of light emitting units disposed on the array substrate, each having a plurality of sub-light emitting units, and a plurality of fingerprint recognition units, configured to recognize fingerprints based on light reflected by a touch object to the fingerprint recognition units. Each fingerprint recognition unit is configured in coordination with at least one sub-light emitting unit. An orthogonal projection of each fingerprint recognition unit on the array substrate and an orthogonal projection of a corresponding sub-light emitting structure on the array substrate overlap with each other.
