Abstract

The invention provides a fingerprint unlocking method and device, and belongs to the technical field of the terminal. The method comprises the following steps: detecting whether the pressure of the fingerprint pressing achieves the preset threshold if detecting that the fingerprint pressing on a touch screen is effective fingerprint pressing, wherein the touch screen is in an off screen display state; awakening a terminal system when the pressure of the fingerprint pressing achieves the preset threshold; switching the touch screen to the on state from the off display state; and unlocking the terminal when the acquired fingerprint feature information is successfully connected with a fingerprint template. When the terminal waits for unlocking, the terminal system is awakened when the effective fingerprint pressing on the touch screen is detected and the pressure is greater than the preset threshold, and the terminal is unlocked when the acquired fingerprint feature information is successfully matched. A reasonable and effective in-screen fingerprint unlocking method is provided, the phenomenon of touching the screen by mistake by the user is effectively avoided, the effectiveness andthe accuracy of the unlocking are guaranteed.

Description

Technical field [0001] The present disclosure relates to the field of terminal technology, and in particular to a fingerprint unlocking method and device. Background technique [0002] With the development of science and technology, optical fingerprint sensing technology and the self-luminous characteristics of OLED (Organic Light-Emitting Diode) screen make it possible to combine the full screen and front fingerprint recognition of mobile phones, 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 mobile terminals such as released mobile phones. Correspondingly, the fingerprint unlocking process based on in-screen fingerprint recognition is also in the exploratory stage, and how to achieve reasonable and effective fingerprint unlocking based on in-screen fingerprint recognition is a proble...
