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.

Abstract: A display panel and an electronic device are provided. The display panel includes a display area. The display area includes a first display area and a second display area at least partially surrounds the first display area. The first display area has greater light transmittance than the second display area. The display panel further includes a substrate, and a display array on the substrate. The display array includes light emitting elements arranged in the display area. The light emitting elements arranged in the first display area are grouped into at least one light emitting element group. The light emitting elements in the same light emitting element group share a same anode, and therefore are controlled to emit light synchronously via the anode, to decrease a lightproof structure in the first display area in size and improving the light transmittance of the first display area.
