Abstract

The invention provides a terminal, an ultrasonic fingerprint unlocking method and an unlocking device. A touch display screen of the terminal and a terminal shell define a containing part. An ultrasonic fingerprint sensor is arranged in the portion, at the inner side of a fingerprint recognition part on the lower portion of the touch display screen, of the containing part. A first distance sensor is arranged in the portion, on the upper portion of the touch display screen, of the containing part. The terminal comprises a second distance sensor, wherein the second distance sensor is close to the ultrasonic fingerprint sensor, arranged in the portion, on the lower portion of the touch display screen, of the containing part and used for performing fingerprint recognition on a shelter within a preset distance range of the fingerprint recognition part. Through the technical scheme, the security and reliability of fingerprint recognition are improved, and power consumption of the terminal is lowered.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular, to a terminal, an ultrasonic fingerprint unlocking method and an ultrasonic fingerprint unlocking device. Background technique [0002] With the development of electronic information technology, fingerprint identification technology is also applied to the touch screen operating system, which brings convenience for people to operate electronic equipment. [0003] Unlike the existing touch screen fingerprint recognition, because ultrasonic waves (sound waves with a frequency higher than 20,000 Hz) have good directionality and strong penetrating ability, they can recognize the three-dimensional details and unique fingerprint characteristics of the user's finger. Therefore, Now more and more manufacturers of electronic equipment prefer to use ultrasonic fingerprint sensors for non-contact fingerprint identification, which effectively improves the efficiency and reliability of...
