Embodiment Construction

[0045] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0046] The invention provides a fingerprint unlocking method, such as figure 1 As shown, a schematic flow chart of the first embodiment of the fingerprint unlocking method of the present invention is shown, and the method includes:

[0047] S10. When the mobile terminal is in the locked screen state, control the ultrasonic sensor of the mobile terminal to scan in real time to capture the fingerprint of the user touching the preset unlocking area on the surface of the mobile terminal;

[0048] The mobile terminal can be an intelligent terminal with a display screen, such as a mobile phone, a tablet computer, a vehicle-mounted intelligent terminal, and a wearable device. The display screen of the mobile terminal has two working states, one is an unlocked state, and the other is a locked screen state. When the display ...

Abstract

The invention discloses a fingerprint unlocking method. The fingerprint unlocking method includes the steps that when a mobile terminal is in a screen locked state, an ultrasonic sensor of the mobile terminal is controlled to carry out real-time scanning to capture fingerprints generated when a user touches an unlocking region preset on the surface of the mobile terminal; the fingerprints are imaged when the fingerprints are scanned in the unlocking region, and fingerprint feature data in fingerprint information obtained after imaging is completed is matched with fingerprint feature data in saved fingerprint passwords one to one; when at least one piece of fingerprint feature data in the fingerprint information is matched with the fingerprint feature data in the fingerprint passwords, a display screen of the mobile terminal is unlocked. The invention further discloses a fingerprint unlocking system and the mobile terminal. Fingerprint unlocking on the mobile terminal is achieved through the ultrasonic sensor, and the accuracy of fingerprint unlocking on the mobile terminal is improved.

Description

technical field [0001] The present invention relates to the field of mobile terminals, in particular to a fingerprint unlocking method, system and mobile terminal. Background technique [0002] With the progress and development of technology, mobile terminals have become an indispensable device in people's daily life, and the functions of mobile terminals are becoming more and more powerful. At present, the screens of mobile terminals such as mobile phones and tablet computers can be unlocked by means of slide unlocking, Jiugongge unlocking, fingerprint unlocking and the like. Compared with fingerprint unlocking, slide unlocking is simpler and easier to use. However, the existing fingerprint unlocking mainly relies on the fingerprint scanning sensor installed inside the mobile phone screen or on the back of the mobile phone body. This fingerprint unlocking method is in the unlocking area of ​​the finger or mobile terminal When there are stains on the screen, it is difficult...
