The present invention proposes a control method of the lock screen based on a touch input detected in the locked state, and displays an execution screen of an application on a lock screen displayed in a locked state of the portable electronic device.

Hereinafter, a control method of the lock screen displayed in the locked state of the portable electronic device will be described with reference to FIG. 3 together with FIG. 1 and FIG.

3 is a flowchart illustrating a method of controlling a portable electronic device according to an embodiment disclosed herein.

First, a control method of a portable electronic device according to an embodiment of the present invention executes a lock state when the portable electronic device meets a condition set in the released state (S100). Next, the control method of the portable electronic device displays the application execution screen on the lock screen displayed in the locked state (S110). In addition, the control method controls the lock screen based on the touch input sensed in the locked state (S120).

The portable electronic device according to an embodiment of the present invention is divided into a 'locked state' and a 'released state' depending on whether the user inputs a control command to the portable electronic device.

First, the locked state is a state of restricting input of a user's control command to applications included in the portable electronic device. This is to prevent the functions and applications of the portable electronic device from being activated or deactivated by inputting a control command that is not intended by a user in a portable electronic device mainly equipped with the touch screen 151. [ Accordingly, in the locked state, the input of the user's control command input through the touch screen 151 and the other user input unit 130 is limited within a set range.

On the other hand, in the locked state, the input of the user's control command is limited, but the functions of the portable electronic device and the operations of the applications that were operating before the locked state was executed can be continuously executed.

The cancel state is a state in which the input of the user's control command to the portable electronic device is not restricted. Therefore, the functions and applications of the portable electronic device are activated or deactivated according to a control command input by the user in the released state.

Here, the locked state may be executed when the user's input is not detected for a predetermined time with respect to the touch screen 151 and other user input units 130 provided in the portable electronic device. The set time may be changed according to the setting of the user.

Also, the locked state may be executed when the user presses a special key (e.g., a hold key) provided in the portable electronic device set in advance for the locked state.

In this specification, when the input of the user is not detected in the portable electronic device for the set time or when the input of the special key is detected and the lock state is executed, if the set condition is satisfied, Can be expressed as 'execute'.

The release state may be executed by the user again pressing the special key in the locked state or by touch input sensed on the lock screen displayed in the locked state.

Here, the application corresponding to the execution screen displayed on the lock screen may be the last displayed before the lock status is executed, or the application corresponding to the screen captured by the user's capture command before the lock status is executed . The application corresponding to the execution screen displayed on the lock screen may be an application executing in the locked state or an application in which a new event is generated in the locked state. The application corresponding to the execution screen displayed on the lock screen may be an application that was executed before the lock status was executed.

Hereinafter, embodiments in which the control method is applied will be described.
