Abstract

An apparatus and method for automatically controlling screens displayed on two display units installed in a mobile terminal are provided. The apparatus includes a first display disposed on a front surface of the mobile device; a first user input device disposed on the front surface; a second display disposed on a rear surface of the mobile device; a second user input device disposed on the rear surface; and a controller configured to selectively operate at least one of the first display, the second display, the first user input device, and the second user input device according to detecting a user input or an operation being performed by the mobile device.

Claims

1. A mobile device comprising:

a first display disposed on a front surface of the mobile device;

a first user input device disposed on the front surface;

a second display disposed on a rear surface of the mobile device;

a second user input device disposed on the rear surface; and

a controller configured to selectively operate the first display and the first user input device, or the second display and the second user input device, according to detecting a user input or an operation being performed by the mobile device.

2. The mobile device of claim 1, wherein the controller is further configured to change an activation state by activating one of the first display and the second display, and displaying a screen of a function corresponding to the one of the first display and the second display.

3. The mobile device of claim 2, wherein the screen of the function is customized to a size of the one of the first display and the second display.

4. The mobile device of claim 1, wherein the controller is further configured to change the activation state by activating the first display and the second display, and simultaneously displaying a screen corresponding to a function on the first display and the second display.

5. The mobile device of claim 1, wherein the controller is further configured to change an activation state by activating the first display and the second display, and displaying a first screen corresponding to a first function on the first display, and displaying a second screen corresponding to a second function on the second display, based on motion information.

6. The mobile device of claim 1, wherein the controller is further configured to change an activation state by activating the first display and the second display, and displaying a first screen corresponding to a first function on the first display, and displaying a second screen corresponding to a second function on the second display, based on the user input.

7. The mobile device of claim 1, wherein the controller is further configured to automatically control activation states of the first display and the second display, according to operation control information.

8. A method comprising:

detecting, by a mobile device, a user input or an operation of the mobile device, wherein the mobile device includes a first display disposed on a front surface of the mobile device, a first user input device disposed on the front surface, a second display disposed on a rear surface of the mobile device, and a second user input device disposed on the rear surface; and

selectively operating the first display and the first user input device, or the second display and the second user input device, according to the detection of the user input or the operation of the mobile device.

9. The method of claim 8, further comprising:

acquiring, by a sensing unit, a motion information value associated with the mobile device;

extracting, from the motion information value, operation control information for at least one of the first display and the second display; and

changing an activation state of at least one of the first display and the second display, based on the operation control information.

10. The method of claim 9, wherein changing the activation state comprises:

activating one of the first display and the second display; and

displaying a screen of a function corresponding to the one of the first display and the second display.

11. The method of claim 10, wherein the screen of the function is customized to a size of the one of the first display and the second display.

12. The method of claim 9, wherein changing the activation state comprises:

activating the first display and the second display; and

simultaneously displaying a screen corresponding to a function on the first display and the second display.

13. The method of claim 9, wherein changing the activation state comprises:

activating the first display and the second display; and

displaying a first screen corresponding to a first function on the first display, and displaying a second screen corresponding to a second function on the second display, based on the motion information.

14. The method of claim 9, wherein changing the activation state comprises:

activating the first display and the second display; and

displaying a first screen corresponding to a first function on the first display, and displaying a second screen corresponding to a second function on the second display, based on the user input.

15. The method of claim 9, further comprising transmitting image data to at least one of the first display and the second display, according to a specification of at least one of the first display and the second display.

16. The method of claim 9, wherein the sensing unit includes at least one of an acceleration sensor and a gyro sensor.

17. The method of claim 9, further comprising changing a location of a screen corresponding to a function according to the changed activation state.

18. A non-transitory machine-readable storage device storing instructions that, when executed by one or more processors, controls the one or more processors to perform operations in a mobile device including a first display disposed on a front surface of the mobile device, a first user input device disposed on the front surface, a second display disposed on a rear surface of the mobile device, and a second user input device disposed on the rear surface, the operations comprising:

detecting, by the mobile device, a user input or an operation of the mobile device; and

selectively operating the first display and the first user input device, or the second display and the second user input device, according to the detection of the user input or the operation of the mobile device.

19. The non-transitory machine-readable storage device of claim 18, wherein the operations further comprise:

acquiring, by a sensing unit, a motion information value associated with the mobile device;

extracting, from the motion information value, operation control information for at least one of the first display and the second display operatively; and

changing an activation state of at least one of the first display and the second display, based on the operation control information.

20. The non-transitory machine-readable storage device of claim 19, wherein changing the activation state comprises:

activating one of the first display and the second display; and

displaying a screen of a function corresponding to the one of the first display and the second display.
