Abstract

A mobile terminal capable of performing a touch input and a control method therefor are provided. A mobile terminal includes a display unit and a controller. The display unit displays screen information. The controller receives a control signal for setting the screen information as a locked screen, and controls the display unit so that the screen information is output on the display unit, based on the control signal, when a locked state for limiting the input of a control command for an application.

Claims

1. A mobile terminal, comprising:

a display unit configured to receive inputs and display information; and

a controller configured to;

receive a control signal for setting a lock state of a screen of the display unit, the lock state limiting input of a control command for an application being executed; and

control the display unit to set the lock state of the screen and display locked screen information in response to the control signal.

2. The mobile terminal of claim 1, wherein the controller is further configured to control the display unit to set the locked screen information to information displayed on the screen when the control signal is received.

3. The mobile terminal of claim 2, wherein the controller is further configured to:

capture an image of information displayed on the screen when the control signal is received; and

control the display unit to set the captured image as the locked screen information.

4. The mobile terminal of claim 1, wherein the controller is further configured to control the display unit to:

display a graphic for selecting the locked screen information; and

set the locked screen information in response to selection of the graphic.

5. The mobile terminal of claim 1, wherein the control signal is generated when no user input is received on the screen for a predetermined time interval.

6. The mobile terminal of claim 1, wherein the controller is further configured to control the display unit to set the locked screen information to an execution screen of the application.

7. The mobile terminal of claim 6, wherein the controller is further configured to control the display unit to update the execution screen set as the locked screen information during the lock state such that updated information corresponding to the application is displayed.

8. The mobile terminal of claim 7, wherein the controller is further configured to control the display unit to update the execution screen set as the locked screen information in real time or at a predetermined interval.

9. The mobile terminal of claim 1, wherein the controller is further configured to control the display unit to allow a control command for the application to be received via a specific region on the screen while the lock state is set.

10. The mobile terminal of claim 9, wherein the control command is received via on a touch input on the specific region.

11. The mobile terminal of claim 9, wherein the controller is further configured to control the display unit to display the specific region to be distinguished from other regions on the screen.

12. The mobile terminal of claim 1, wherein the controller is further configured to:

control the display unit to display a plurality of graphics on the screen during the lock state, each of the plurality of graphics corresponding to different screen information;

process a touch input to select one of the plurality of graphics, the touch input satisfying a release condition; and

control the display unit to release the locked state of the screen and display information corresponding to the selected one of the plurality of graphics on the screen.

13. The mobile terminal of claim 12, wherein:

the touch input is received on a specific one of the plurality of graphics that corresponds to screen information of the received control signal; and

the controller is further configured to execute an application corresponding to the screen information of the received control signal in response to the touch input.

14. The mobile terminal of claim 1, wherein the controller is further configured to:

control the display unit to display a graphic for controlling illumination of the display unit on the locked screen;

process a touch input to the displayed graphic; and

illuminate the display unit during the locked state of the screen based on the touch input.

15. A method for controlling a mobile terminal, the method comprising:

displaying information on a display unit of the mobile terminal;

receiving a control signal for setting a lock state of a screen of the display unit, the lock state limiting input of a control command for an application being executed; and

setting the lock state of the screen and displaying locked screen information in response to the control signal.

16. The method of claim 15, further comprising:

setting the locked screen information to information displayed on the screen when the control signal is received.

17. The method of claim 15, wherein the control signal is generated when no user input is received on the screen for a predetermined time interval.

18. The method of claim 15, further comprising:

setting the locked screen information to an execution screen of the application.

19. The method of claim 15, further comprising allowing a control command for the application to be received via a specific region on the screen while the lock state is set.

20. The method of claim 15, further comprising:

displaying a plurality of graphics on the screen during the lock state, each of the plurality of graphics corresponding to different screen information;

processing a touch input to select one of the plurality of graphics, the touch input satisfying a release condition; and

releasing the locked state of the screen and displaying information corresponding to the selected one of the plurality of graphics on the screen.
