Abstract

The invention discloses a screen unlocking method and device and a terminal, and belongs to the field of man-machine interaction. The method is applied in the terminal which is provided with a touch display screen, and the touch display screen is provided with a fingerprint sensor. The method comprises the following steps of: when a touch operation acting on the touch display screen is received under a screen locked state, acquiring fingerprint information corresponding to the touch operation through the fingerprint sensor; matching the fingerprint information with a preset fingerprint template; and when the fingerprint information is matched with the fingerprint template and the touch time length of the touch operation is greater than a first preset time length, maintaining the screen locked state. According to the method, the problem that the switching of the terminal from the screen locked state to an unlocked state is incorrect is solved, and the correctness of switching working state of the display screen by the terminal is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of human-computer interaction, and in particular to a screen unlocking method, device and terminal. Background technique [0002] The working state of the touch display screen in the terminal includes a locked screen state and an unlocked state. In the lock screen state, the backlight circuit in the touch display is cut off. When switching from the locked screen state to the unlocked state, the backlight circuit in the touch screen is connected, and the brightness of the touch screen returns to normal brightness. [0003] A fingerprint recognition sensor is arranged in the touch display screen with fingerprint recognition function. When the working state of the touch screen is the lock screen state, if the fingerprint recognition sensor scans the fingerprint information, the terminal will match the fingerprint information with the preset fingerprint template; if the fingerprint information matc...
