For example, the controller 160 generates an unlock pattern by combining one or more first body rear button inputs and / or one or more second body rear button inputs (or first user inputs).

In the case of the conventional unlocking pattern using the touch panel, there is a possibility that the unlocking pattern is exposed to others due to the traces remaining on the display portion (or the liquid crystal display).

However, since the unlock pattern according to the embodiment of the present invention is set by an existing physical button (for example, a main body rear button), it is possible to leave no traces of the user on the liquid crystal.

In addition, the unlock pattern setting according to the embodiment of the present invention can be easily set by a user with one hand.

FIGS. 4 to 6 are diagrams for explaining a method of setting an unlock pattern according to an embodiment of the present invention.

4 is a view showing an object used for unlocking displayed on the display unit 130. FIG.

As shown in FIG. 4, the display unit 130 displays one or more objects used for unlocking.

According to an embodiment of the present invention, the user input 120 generates a second user input based on a user input to the object.

For example, a second user input may be generated by a combination of one or more objects among a plurality of objects 310 to 390 displayed on the display unit 130. [

Also, the controller 160 generates an unlock pattern based on at least one of the first user input and the second user input.

That is, when the first user input is effectively generated, the controller 160 generates an unlock pattern based on the combination of the second user input.

For example, when the user manipulation button 110 provided on the rear case or the rear surface of the main body is pressed (or selected / touched), the control unit 160 determines, based on the combination by the second user input, .

Also, the object used for the unlocking may be expressed in a plurality of modes.

4 (a) is an example of a first mode of an object used for unlocking. 4 (b) is an example of a second mode of the object used for unlocking. At this time, according to each mode, if a user input is performed to an object, the user input to be acquired by the user input unit 120 may be different. Here, in the first mode, an object composed of a plurality of different numbers (or different characters) is displayed. In the second mode, a plurality of different characters (e.g., a Korean consonant, ) (Or a different number) may be displayed.

For example, when a user input is performed on the object shown in FIG. 4A, the user input unit 120 may obtain a user input in the form of a number.

4 (b), the user input unit 120 may obtain a user input in a character form.

According to the embodiment of the present invention, the control unit 160 may convert (or change) the object used for unlocking from the preset first mode to the second mode based on the first user input.

That is, when the first user input continues for a predetermined time or longer, the controller 160 may convert the object from the first mode to the second mode.

5 is a diagram for explaining an example of mode conversion.

1, a, 5, i 'are set as the unlock pattern.

According to the present embodiment, when the first user input continues for a predetermined time or longer, the controller 160 converts the state of the object from the first mode to the second mode.

If there is no input of the first user, the controller 160 displays the object in the first mode on the display unit 130.

Therefore, in order to input '1', only the input to the object 310 is required without inputting to the user operation button 110. On the other hand, in order to input 'a', both the input to the user operation button 110 and the input to the object 310 are required. Similarly, in order to input '5', only the input to the object 350 is needed without the input to the user operation button 110. In order to input 'i', both the input to the user operation button 110 and the input to the object 390 are required.

According to this embodiment, when the first user input is continued, the controller 160 may convert the object from the first mode to the second mode.

6 is a diagram for explaining another example of mode conversion.

Similarly, it is assumed that '1, a, 5, i' is set as an unlock pattern.

According to the present exemplary embodiment, when the first user input is obtained, the controller 160 converts the state of the object from the first mode to the second mode.

If there is no first user input, the control unit 160 displays the previous state of the object on the display unit 130. At this time, it is assumed that the display unit 130 initially displays an object of the first mode.

Accordingly, in order to input '1', only input to the object 310 is required without inputting to the user operation button 110. On the other hand, in order to input 'a', both the input to the user operation button 110 and the input to the object 310 are required.
