Abstract

A method for controlling a portable device and which includes detecting one of a first unlock command for switching a state of a first display unit to an active state and maintaining a state of a second display unit in a locked state or a second unlock command for switching the state of the first display unit to the active state and switching the state of the second display unit to a ready-to-activate state; switching the states of the first and second display units to the active state and the ready-to-activate state, respectively, when the second unlock command is detected; detecting an unlock trigger; and switching the second display unit to the active state according to the detected unlock trigger.

Claims

1. A method for controlling a portable device including first and second display units at opposing surfaces of the portable device, the method comprising:

detecting, via a controller of the portable device, an unlock command for switching a state of the first display unit from a first locked state to an active state and switching a state of the second display unit from a second locked state to a ready-to-activate state;

switching, via the controller, the state of the first display unit to the active state and switching the state of the second display unit to the ready-to-activate state when the unlock command is detected;

detecting, via the controller, an unlock trigger for switching the state of the second display unit, which is in the ready-to-activate state, to the active state; and

switching, via the controller, the state of the second display unit, which is in the ready-to-activate state, to the active state according to the detected unlock trigger,

wherein the ready-to-activate state is an intermediate state between the second locked state and the active state.

2. The method according to claim 1, wherein the unlock trigger for the second display unit is generated as the portable device is rotated such that the second display unit faces a user or is generated upon execution of an application that operates in conjunction with the second display unit.

3. The method according to claim 2, wherein, when the portable device is rotated, the switching of the state of the second display unit to the active state includes activating a light emitting element of the second display unit when the portable device has been rotated by a first threshold angle and activating a touch sensor of the second display unit when the portable device has been rotated by a second threshold angle that is equal to or greater than the first threshold angle.

4. The method according to claim 2, further comprising:

deactivating at least one of a light emitting element and a touch sensor of the first display unit when the portable device rotates.

5. The method according to claim 2, wherein, when the application that operates in conjunction with the second display unit is executed, the switching of the state of the second display unit to the active state includes activating at least one of a light emitting element and a touch sensor of the second display unit according to control of the application.

6. The method according to claim 1, wherein the first display unit faces a user and the second display unit faces the opposite direction of the first display unit.

7. The method according to claim 1, wherein the unlock trigger is detected through at least one of a touch sensor, a gravity sensor, a motion sensor, a gyro sensor, an acceleration sensor, an inclination sensor, and a brightness sensor.

8. The method according to claim 1, wherein the unlock command is detected simultaneously by a touch sensor of the first display unit and a touch sensor of the second display unit.

9. The method according to claim 1, wherein the unlock command is determined based on a touch region detected by a touch sensor of the first display unit.

10. The method according to claim 1, further comprising:

displaying content on the first display unit; and

displaying detailed content on the second display unit associated with the content displayed on the first display unit, when the unlock trigger for the second display unit is detected.

11. The method according to claim 1, wherein, in the ready-to-activate state, the state of the second display unit is switched to the active state by detecting the unlock trigger without simultaneously detecting the unlock command.

12. The method according to claim 1, wherein, in the first locked state, the first display unit partially activates a touch sensor or a light emitting element.

13. The method according to claim 1, wherein, in the second locked state, a light emitting element and a touch sensor of the second display unit are inactive.

14. A portable device comprising:

a first and a second display units at opposing surfaces of the portable device configured to display content; and

a controller configured to;

detect an unlock command for switching a state of the first display unit from a first locked state to an active state and-switching a state of the second display unit from a second locked state to a ready-to-activate state,

switch the state of the first display unit to the active state and switch the state of the second display unit to the ready-to-activate state when the unlock command is detected,

detect an unlock trigger for switching the state of the second display unit, which is in the ready-to-activate state, to the active state, and

switch the state of the second display unit, which is in the ready-to-activate state, to the active state according to the detected unlock trigger,

wherein the ready-to-activate state is an intermediate state between the second locked state and the active state.

15. The portable device according to claim 14, wherein the unlock trigger for the second display unit is generated as the portable device is rotated such that the second display unit faces a user or is generated upon execution of an application that operates in conjunction with the second display unit.

16. The portable device according to claim 15, wherein, when the portable device is rotated, the switching of the state of the second display unit to the active state includes the controller activating a light emitting element of the second display unit when the portable device has been rotated by a first threshold angle and activating a touch sensor of the second display unit when the portable device has been rotated by a second threshold angle that is equal to or greater than the first threshold angle.

17. The portable device according to claim 15, wherein the first display unit includes at least one of a light emitting element and a touch sensor, and the controller is further configured to deactivate said at least one of the light emitting element and the touch sensor of the first display unit when the portable device rotates.

18. The portable device according to claim 15, wherein, when the application that operates in conjunction with the second display unit is executed, the switching of the state of the second display unit to the active state includes the controller activating at least one of a light emitting element and a touch sensor of the second display unit according to control of the application.

19. The portable device according to claim 14, wherein the first display unit faces a user and the second display unit faces the opposite direction of the first display unit.

20. The portable device according to claim 14, wherein the unlock trigger is detected through at least one of a touch sensor, a gravity sensor, a motion sensor, a gyro sensor, an acceleration sensor, an inclination sensor, and a brightness sensor.

21. The portable device according to claim 14, wherein the controller is further configured to detect the unlock command by a simultaneously touching of a touch sensor of the first display unit and a touch sensor of the second display unit.

22. The portable device according to claim 14, the unlock command is determined based on a touch region detected by a touch sensor of the first display unit.

23. The portable device according to claim 14, wherein when the controller detects the unlock trigger for the second display unit, the controller is further configured to display detailed content on the second display unit associated with the content displayed on the first display unit.

24. The portable device according to claim 14, wherein, in the ready-to-activate state, the state of the second display unit is switched to the active state by detecting the unlock trigger without simultaneously detecting the unlock command.

25. The portable device according to claim 14, wherein, in the first locked state, the first display unit partially activates a touch sensor or a light emitting element.

26. The portable device according to claim 14, wherein, in the second locked state, a light emitting element and a touch sensor of the second display unit are inactive.
