Abstract

The embodiment of the invention discloses a fingerprint identification method and a related product. The fingerprint identification method is applied to electronic equipment, and the electronic equipment comprises a display screen module, wherein the display screen module comprises an ultrasonic module and a display screen. The fingerprint identification method comprises the steps: obtaining a first fingerprint image through an ultrasonic module when a first position of a display screen is in a touched state, and matching the first fingerprint image with a preset fingerprint template to obtaina first matching result; if the first matching result is matching failure, sending prompt information to prompt the target object to adjust the finger touch position, obtaining a second fingerprint image through an ultrasonic module, and matching the second fingerprint image with a preset fingerprint template to obtain a second matching result; and if the second matching result is matching failure, determining whether fingerprint identification succeeds or not according to the first matching result and the second matching result, and if the fingerprint identification succeeds, executing preset unlocking operation, so that the fingerprint identification efficiency is improved.
