When the user presses the lock button in the lock mode, the control unit 180 detects the input of the lock button and controls the power supply unit 190 to supply power to the display unit 151 at step S102. In other words, upon receipt of the unlock command, the controller 180 supplies power to the display unit 151.

Then, the control unit 180 displays at least one or more lock screens on the display unit screen (S103). The lock screen may be screen information provided from a terminal connected to the mobile terminal 100 through an DLNA (Digital Living Network Alliance) network or an execution screen of an application. For example, when a terminal such as a personal computer, a television (TV), or a camera is connected to the mobile terminal 100 using the DLNA network, the mobile terminal 100 displays screen information displayed on the display screen of the connected terminals And displays a player screen for reproducing media content transmitted from the connected terminal in a thumbnail form.

The control unit 180 selects at least one of the lock screens displayed on the display screen according to a user input (S104). For example, when a plurality of lock screens are displayed in a thumbnail form as shown in FIG. 5, the controller 180 records a lock screen and a lock screen selection order selected by the user.

The controller 180 determines whether the selected lock screen and the lock screen selection sequence coincide with predetermined information (S105).

If it is determined that the selected lock screen and the lock screen selection sequence coincide with predetermined information, the controller 180 cancels the screen lock (S106).

On the other hand, if the selected lock screen and the lock screen selection sequence do not coincide with preset information, the control unit 180 outputs a notification signal informing of the mismatch (S107). The notification signal may be output as a sound effect and / or a message.

In the present embodiment, a predetermined number of lock screens are selected in order, but it is also possible to perform unlocking through at least two lock screen combinations. For example, if two or more predetermined screens of the plurality of lock screens are selected, the controller 180 unlocks the selected one.

6 is a flowchart illustrating an unlocking method of a mobile terminal according to a second embodiment of the present invention.

The control unit 180 of the mobile terminal 100 controls the power supply unit 190 when there is no input or a lock button is input for a predetermined period of time while using the mobile terminal 100, And sets it to the lock mode (S201).

When the user presses the lock button in the lock mode, the controller 180 detects the input of the lock button, and controls the power supply unit 190 to supply power to the display unit 151 (S202).

Then, the controller 180 displays a plurality of lock screens on the display unit screen (S203).

If at least one of the plurality of lock screens is selected, the controller 180 enlarges the selected lock screen to the entire display screen and requests a password input (S204, S205).

If the user inputs a password in response to the password input request, the controller 180 determines whether the input password and the selected lock screen coincide with predetermined lock setting information (S206, S207).

If it is determined that the input password and the selected lock screen coincide with predetermined lock setting information, the controller 180 cancels the screen lock (S208).

If the input password and / or the selected lock screen do not coincide with predetermined lock setting information, the controller 180 displays a notification signal indicating that the input password and the selected lock screen do not match preset lock setting information (S209). At this time, the control unit 180 may request to input the password and / or select the lock screen after outputting the notification signal.

FIG. 7 shows an example of performing an unlocking operation in the mobile terminal according to the embodiment of FIG.

First, when the lock button is pressed while the power supply to the display unit 151 is cut off, the controller 180 supplies power to the display unit 151 and displays a plurality of lock screens on the display unit 151 a). When a predetermined screen among a plurality of lock screens displayed through the display unit 151 is selected by a user, the controller 180 requests a password input. If the user inputs a password in response to the password input request, the controller 180 determines whether the selected screen is a screen that can be unlocked, and checks whether the password input by the user matches the preset password.

On the other hand, if the selected screen is a screen that can be unlocked or the received password is inconsistent with the preset password, the controller 180 outputs a notification signal (e.g. Here, if the selected screen is a screen which can not be unlocked, the controller 180 does not release the lock mode even if the user inputs the correct password on the selected screen.

After the notification signal is output, the control unit 180 may reselect a predetermined lock screen or re-input a password according to user input. For example, as shown in (b) of FIG. 7, a predetermined lock screen among a plurality of lock screens is reselected through a touch-and-drag input on a previously selected lock screen. At this time, the control unit 180 displays a lock screen following the lock screen displayed on the display screen according to the touch and drag input (c). If there is no touch and drag input for a predetermined time in the state of displaying the next lock screen, the controller 180 requests the password input.

If the reselected predetermined lock screen is an unlockable screen and the received password matches a predetermined password, the controller 180 cancels the lock mode.

8 shows an example in which the mobile terminal according to the third embodiment of the present invention performs multiple unlocking. The present embodiment will be described by taking as an example a case where a lock mode is set for each screen of other terminals connected through the DLNA network.

When the controller 180 of the mobile terminal 100 detects the input of the lock button while the power supplied to the display unit 151 is turned off, the controller 180 of the mobile terminal 100 displays thumbnails of the lock screens of the terminals connected to the DLNA network, 210 (a). The display screen includes an area 210 for displaying the lock screens and an unlock board 220.

When a predetermined lock screen is selected from among the lock screens and the selected lock screen is moved to the unlock board 220, the controller 180 performs an unlock operation on the selected lock screen. For example, the control unit 180 of the mobile terminal 100 displays a mobile terminal screen, a TV screen, a personal computer screen, and the like in a thumbnail form. When the TV screen is dragged and moved to the unlocking board among the displayed screens, the controller 180 cancels the lock mode of the TV screen and displays the TV screen on the display screen.

In addition, if a predetermined lock screen is selected among a plurality of lock screens, the controller 180 records the selection order of the lock screen. Then, when the lock screen selection is completed, the controller 180 arranges the terminal screen based on the recorded lock screen selection order. For example, the control unit 180 disposes the terminal screen corresponding to the first selected lock screen on the front of the display screen, unlocks the terminal screen corresponding to the next selected lock screen, and disposes it in the background (b).
