Abstract

The embodiment of the invention provides an unlocking method of a touch screen. The unlocking method comprises the following steps of: A, receiving touch information on the touch screen in a screen lock state; and B, when judging that a preset touch track is constructed by touch points included in the touch information and when judging that the pressure amplitude of a part of track preset on the touch track is matched with the preset pressure amplitude, unlocking the touch screen. The embodiment of the invention also provides an unlocking device of the touch screen. By arranging the unlocking information as the touch track and applying pressure value information to the touch track, the unlocking information of the touch screen has higher security, and the system is safer in use.

Description

technical field [0001] The present invention relates to the technical field of touch screens, and in particular, to a method and device for unlocking a touch screen. Background technique [0002] At present, the touch screen is usually unlocked by touch operation.
