Abstract

Embodiments of the present disclosure provide a display apparatus, a fingerprint identification method thereof, and an electronic device. The display apparatus includes: an organic light emitting layer and a fingerprint identification array. The organic light emitting layer includes a plurality of organic light emitting configurations. In a fingerprint identification phase, the plurality of organic light emitting configurations are arranged to emit light according to a first light emitting lattice and shift. A distance between any two adjacent organic light emitting configurations in the first light emitting lattice is greater than or equal to a minimum crosstalk-free distance. The minimum crosstalk-free distance is a maximum radius of a covering region formed on the fingerprint identification array by the light emitted from any organic light emitting configuration and then reflected through the first surface of the cover plate.
