1. A display apparatus, comprising:

  • a display panel and a cover plate disposed on the display panel, wherein the display panel comprises an array substrate, an organic light emitting layer disposed at one side of the array substrate facing the cover plate, and a fingerprint identification array;

    the organic light emitting layer comprises a plurality of organic light emitting configurations, wherein light emerges from a first surface of the cover plate facing away from the array substrate;

    wherein in a fingerprint identification phase, the plurality of organic light emitting configurations are arranged to emit light according to a first light emitting lattice, wherein the first emitting lattice comprises a plurality of organic light emitting configurations being illuminated, and the first emitting lattice shifts for each frame to be displayed;

    wherein 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, wherein 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 reflected through the first surface of the cover plate.
