Abstract
An embodiment of the present application provides an optical fingerprint identification apparatus, which includes: at least one non-visible light source, configured to emit non-visible light to a human finger to provide excitation light for fingerprint identification; an optical component, disposed under a fingerprint detecting area of the display screen, and configured to receive signal light scattered and reflected by the human finger; and a fingerprint sensor configured to perform imaging based on the signal light passing through the optical component, where a working wave band of the fingerprint sensor is the same as a light emitting wave band of the non-visible light source, a number of the working wave bands is the same as the number of the light emitting wave bands, and the fingerprint sensor is connected to the non-visible light source, and is configured to control the non-visible light source to actively emit light.
