It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. When the portable electronic terminal is unlocked in the related art, it is necessary to perform a specific unlocking operation to a specific position of the touch screen, which causes a problem of inconvenience to the user. Embodiments of the present invention provide a portable electronic terminal, and a method and apparatus for unlocking the portable electronic terminal. When the mobile electronic terminal unlocks the operation, the portable electronic terminal can be unlocked when the moving speed of the contact with the touch screen is greater than a preset value, and the unlocking operation can be performed at any position on the touch screen, thereby facilitating the user to unlock the operation and improving the user experience, in particular Suitable for portable electronic terminals with large screen sizes. According to an embodiment of the present invention, a method for unlocking a portable electronic terminal is provided. As shown in FIG. 1, the method may include the following steps (step S102 - step S106): Step S102, detecting a touch screen with a portable electronic terminal contact. Portable electronic terminals such as mobile phones, tablets and personal digital assistants (PDAs) are increasingly using touch screens as displays and user input devices, and users can interact with the terminals by touching the touch screen position corresponding to the user interface objects. , greatly improved the user experience. However, portable electronic terminals using touch screens have problems inadvertently activating or deactivating certain functions due to the screen being accidentally touched. It is often necessary to set a lock screen to protect, and when the user needs to interact with the terminal, it is unlocked by a specific method. When the touch screen is in the lock screen state, the lock screen prompt can be displayed on the touch screen, and the touch screen is in the detection state, and the contact with the touch screen can be detected. In the embodiment of the present invention, in order to enable the user to conveniently perform the unlocking operation, the user can perform the unlocking operation at any position on the touch screen of the portable electronic terminal, for example, when the user uses the portable electronic terminal with a large screen size, Open one hand and perform the unlock operation at the specified position, and the unlock operation can be performed at the edge of the touch screen. In order to achieve this, contact with the touch screen at any position can be detected. And, a visual cue can be displayed on the touch screen to prompt the user to perform an unlocking operation, such as prompting the user to unlock by image and/or text. Step S104, acquiring a moving speed of the contact while maintaining continuous contact with the touch screen. After detecting contact with the touch screen, determining whether to maintain continuous contact with the touch screen and moving on the touch screen, if it is detected that the contact moves on the touch screen while maintaining continuous contact with the touch screen, the persistence of the touch screen can be acquired. The speed of movement of the above contact while contacting. In a preferred embodiment of the present invention, the moving distance of the contact may be acquired while maintaining continuous contact with the touch screen in a preset time interval, and the movement of the contact is calculated according to the preset time interval and the acquired moving distance. speed. After acquiring the moving speed of the contact while maintaining the continuous contact with the touch screen, the acquired moving speed and the preset moving speed value are compared, and it is determined whether to unlock the portable electronic terminal according to the comparison result. Step S106: If the moving speed of the contact reaches a preset threshold, unlocking the portable electronic terminal. If the acquired moving speed of the contact reaches a preset threshold, the portable electronic terminal is unlocked, and the portable electronic terminal enters an unlocked state, and the user can interact with the terminal through the touch screen. In practical applications, the moving speed required to unlock the portable electronic terminal can be set to respond to the user's unlocking operation according to different user requirements. With the embodiment of the present invention, the portable electronic terminal is unlocked according to the moving speed of the contact while maintaining contact with the touch screen, and the user can perform the unlocking operation at any position on the touch screen without performing the unlocking operation in a specific posture to a specific position, and only needs to contact When the moving speed reaches a preset threshold, the portable electronic terminal can be unlocked, which is convenient for the user to unlock the operation and improve the user experience.

An unlocking prompt appears on the screen, and the unlocking prompt can be text or graphics. Step S206, the user inputs the medium to start sliding from the contact point. Step S208, calculating a sliding speed according to a reservation rule. The booking rule is that during the sliding process of the user's finger on the screen, the distance of the finger sliding is recorded according to a certain time interval, and then the speed is calculated according to the time and the distance. In step S210, the sliding speed reaches a preset value, and the screen is unlocked. The preset value is a speed threshold. If the sliding speed is greater than the threshold, the screen is unlocked. If it is less than the threshold, the unlocking is not performed. The user can set the threshold of the moving speed according to the usage habits. Embodiment 2 FIG. 3 is a flowchart of a method for unlocking a portable electronic terminal according to Embodiment 2 of the present invention. As shown in FIG. 3, the method may include the following steps (Step S302 - Step S316): Step S302, Touching the screen The device is in the lock screen state, and the lock screen prompt is displayed on the screen. Step S304, the touch screen is in a contact detection state. Step S306, the user touches the screen. In step S308, an unlocking prompt is displayed on the screen. Step S310, detecting whether the user maintains the contact state with the screen. If the contact is not maintained, the unlocking prompt disappears, and the lock screen prompt is redisplayed; otherwise, the unlocking prompt is displayed. In step S312, the user's finger slides on the screen. Step S314, determining whether the sliding speed reaches a preset value according to a predetermined rule, if not, returning to step S310; and reaching the preset value, performing an unlocking action. The predetermined rule is that the moving distance on the screen is continuously taken according to the preset time period, and the moving speed is calculated accordingly. In step S316, the unlocking succeeds, the unlocking prompt disappears, and the user access interface is entered.
