Abstract

The present disclosure provides a fingerprint unlocking method and device, belonging to the technical field of terminals. The method includes: when the terminal is in a state of waiting to be unlocked, if it is detected that the fingerprint pressing on the touch screen is an effective fingerprint pressing, detecting whether the pressing force of the fingerprint pressing reaches a preset threshold, and the touch screen is in an off-screen display state; When the pressing force reaches the preset threshold, wake up the terminal system; switch the touch screen from the off-screen display state to the bright screen state; unlock the terminal when the acquired fingerprint feature information and the fingerprint template are successfully matched. In the present disclosure, when the terminal is waiting to be unlocked, the terminal system is only woken up when an effective fingerprint pressing on the touch screen is detected and the pressing force is greater than a preset threshold, and the terminal is unlocked when the acquired fingerprint feature information and the fingerprint template are successfully matched, providing A reasonable and effective in-screen fingerprint unlocking method effectively avoids the phenomenon that the user touches the screen by mistake, and ensures the effectiveness and accuracy of the unlocking.

Description

technical field [0001] The present disclosure relates to the technical field of terminals, and in particular to a fingerprint unlocking method and device. Background technique [0002] With the development of science and technology, the self-luminous characteristics of optical fingerprint sensing technology and OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) screen make it possible to combine the full screen of mobile phones with front fingerprint recognition, that is, fingerprint recognition in the screen ( Also known as in-screen fingerprint recognition). [0003] At present, the in-screen fingerprint recognition technology is still in the research and optimization stage, and has not been applied to released mobile terminals such as mobile phones. Correspondingly, the fingerprint unlocking process based on in-screen fingerprint recognition is also in the exploratory stage. How to realize reasonable and effective fingerprint unlocking based on in-screen f...
