at least one processor configured to:

provide a lock screen to a display area of at least one of the main display area or the sub display area,

in response to a user input of releasing the lock screen being sensed in the main display area, control the display to provide a first home screen, and

in response to a user input of releasing the lock screen being sensed in the sub display area, control the display to provide a second home screen different from the first home screen.

2. The apparatus of claim 1 , wherein the at least one processor is further configured to, in response to a user input for providing the lock screen being sensed on the display, determine a display area where the lock screen is to be provided based on an orientation of the user terminal apparatus at a time when the user input for providing the lock screen is sensed.

3. The apparatus of claim 2 , wherein the at least one processor is further configured to change at least one of a type or a shape of the lock screen based on the display area where the lock screen is provided.

4. The apparatus of claim 1 , wherein the at least one processor is further configured to, in response to an orientation of the user terminal apparatus being changed while the lock screen is provided, change at least one of a type, a shape or a display area of the lock screen.

5. The apparatus of claim 1 , wherein the at least one processor is further configured to:

provide the lock screen to one of the main display area or the sub display area, and

in response to a user input of touching the lock screen and dragging the touched lock screen in a direction of another display area on the display being sensed, move the lock screen to the other display area.

6. The apparatus of claim 5 , wherein the at least one processor is further configured to, in response to the user input of touching and dragging the lock screen being sensed, change at least one of a type or a shape of the lock screen based on the display area where the lock screen is provided.

7. The apparatus of claim 1 , wherein the at least one processor is further configured to determine at least one of a type of an application to be provided on the home screen or access rights of the application based on the display area where the user input is sensed among the main display area and the sub display area.

8. The apparatus of claim 7 , wherein the at least one processor comprises a graphical user interface (GUI) configured to:

change at least one of the type of the application or the access rights of the application in the home screen, and

provide the home screen.

9. The apparatus of claim 1 , wherein the lock screen is one of a swipe lock screen, a biometric information lock screen, a pattern lock screen, a personal identification number (PIN) lock screen, or a password lock screen.

10. A controlling method of a user terminal apparatus including a display comprising a main display area disposed on a front side of the user terminal apparatus and a sub display area extended from one side of the main display area to be disposed on at least one area of a rear side of the user terminal apparatus, the method comprising:

providing a lock screen to a display area of at least one of the main display area or the sub display area;

in response to a user input of releasing the lock screen being sensed in the main display area, providing a first home screen; and

in response to a user input of releasing the lock screen being sensed in the sub display area, providing a second home screen different from the first home screen.

11. The method of claim 10 , wherein the providing of the lock screen comprises:

sensing a user input for providing the lock screen on the display; and

determining the display area where the lock screen is provided based on an orientation of the user terminal apparatus at a time when the user input for providing the lock screen is sensed.

12. The method of claim 11 , wherein the providing of the lock screen further comprises:

changing at least one of a type or a shape of the lock screen based on the display area where the lock screen is provided.

13. The method of claim 10 , further comprising:

in response to an orientation of the user terminal apparatus being changed while the lock screen is provided, changing at least one of a type, a shape, or the display area of the lock screen.

14. The method of claim 10 , further comprising:

sensing a user input of touching the lock screen and dragging the touched lock screen in a direction of the other display area on the display; and

moving the lock screen to another display area and providing the lock screen.

15. The method of claim 14 , further comprising:

in response to the user input of touching and dragging the lock screen being sensed, changing at least one of a type or a shape of the lock screen based on the display area where the lock screen is provided.

16. The method of claim 10 , wherein the providing of the first home screen or the second home screen comprises determining at least one of a type of an application to be provided or access rights of the application based on the display area where the user input is sensed among the main display area and the sub display area.

17. The method of claim 16 , wherein the providing of the first home screen or the second home screen further comprises including a graphical user interface (GUI) for changing at least one of a type of the application or access rights of the application.

18. The method of claim 10 , wherein the lock screen is one of a swipe lock screen, a biometric information lock screen, a pattern lock screen, a personal identification number (PIN) lock screen, or a password lock screen.

19. A computer executable program code recorded on a computer readable non-transitory storage medium, wherein the computer executable program code when executed by the at least one processor, configures the at least one processor to perform the method of claim 10 .

20. A user terminal apparatus comprising:

a display comprising:

a main display area disposed on a front side of the user terminal apparatus,

a sub display area extended from one side of the main display area to be disposed on at least one area of a rear side of the user terminal apparatus, and

a round display area which connects the main display area and the sub display area; and

at least one processor configured to:

provide a lock screen to a display area of at least one of the main display area, the sub display area, or the round display area,

in response to a user input of releasing the lock screen being sensed in the main display area, control the display to provide a first home screen, and

in response to a user input of releasing the lock screen being sensed in the sub display area, control the display to provide a second home screen different from the first home screen,

wherein the round display area is distinguished from the main display area and the sub display area by border lines set by the user.
