Abstract
A display apparatus and a fingerprint identification method are provided. An exemplary display apparatus includes a display region including a fingerprint identification region; a plurality of fingerprint identification pixels disposed in the fingerprint identification region and configured to provide a fingerprint identification light; a fingerprint identification array including fingerprint sensing units disposed in the fingerprint identification region and configured to receive the fingerprint identification light after being reflected by a touching body; and a controller electrically connected to the fingerprint sensing units and configured to obtain a whole image of a to-be-identified fingerprint, determine position coordinates of characteristic points on the display apparatus according to the whole image, control a first number of the fingerprint identification pixels to emit light according to the position coordinates to obtain local images at characteristic points of the to-be-identified fingerprint, and identify the to-be-identified fingerprint according to the local images.
