Abstract

The present invention is related to a mobile communication terminal capable of displaying a task executed thereon. The mobile communication terminal includes a first display for initially displaying one or more tasks simultaneously being executed on the mobile communication terminal, a second display for subsequently displaying the one or more tasks simultaneously being executed on the mobile communication terminal after a display conversion from the first display to the second display occurs, and a controller operationally connected with the first display and the second display, wherein the controller displays on the second display a highest priority task among the one more tasks simultaneously being executed when the display conversion from the first display to the second display occurs.

Claims

1. A mobile communication terminal capable of displaying a task executed thereon, the mobile communication terminal comprising:

a first display for initially displaying one or more tasks simultaneously being executed on the mobile communication terminal;

a second display for subsequently displaying the one or more tasks simultaneously being executed on the mobile communication terminal after a display conversion from the first display to the second display occurs; and

a controller operationally connected with the first display and the second display, wherein the controller displays on the second display a highest priority task among the one more tasks simultaneously being executed when the display conversion from the first display to the second display occurs.

2. The mobile communication terminal of claim 1, wherein the highest priority task is a task related to a communication function.

3. The mobile communication terminal of claim 1, wherein the highest priority task is a task related to a sound output function.

4. The mobile communication terminal of claim 1, wherein when the highest priority task is not a Latest Recently Used (LRU) task, the controller changes the highest priority task into an LRU task and displays the changed task on the second display.

5. The mobile communication terminal of claim 1, wherein when the highest priority task does not exist, the controller displays a default task.

6. The mobile communication terminal of claim 1, wherein when the highest priority task is finished executing after the display conversion, the controller displays a next highest priority task among the one more tasks simultaneously being executed.

7. The mobile communication terminal of claim 1, wherein the display conversion from the first display to the second display corresponds to a closing operation of a folder type mobile communication terminal.

8. The mobile communication terminal of claim 1, wherein a list of the one or more tasks can be displayed on the second display.

9. The mobile communication terminal of claim 1, wherein during a display return from the second display to the first display, the controller re-displays on the first display a task that was displayed on the first display prior to the occurrence of the display conversion.

10. The mobile communication terminal of claim 9, wherein the display return from the second display to the first display corresponds to an opening operation of a folder type mobile communication terminal.

11. A method for displaying a task executed on a mobile communication terminal, the method comprising:

initially displaying one or more tasks simultaneously being executed on the mobile communication terminal on a first display;

receiving a command for a display conversion from the first display to a second display; and

displaying on the second display a highest priority task among the one more tasks simultaneously being executed in response to the command for the display conversion.

12. The method of claim 11, wherein the displaying step comprises:

comparing priorities of the one or more tasks with each other when receiving the command; and

determining the highest priority task based on the comparison.

13. The method of claim 11, wherein the highest priority task is a task related to a communication function.

14. The method of claim 11, wherein the highest priority task is a task related to a sound output function.

15. The method of claim 11, wherein the displaying step comprises changing the highest priority task into a Latest Recently Used (LRU) task if the highest priority task is not the LRU task.

16. The method of claim 11, wherein a default task is displayed if the highest priority task does not exist.

17. The method of claim 11, further comprising finishing the highest priority task and displaying a next highest priority task on the second display if a command to finish the highest priority task is received after the displaying step.

18. The method of claim 11, wherein the display conversion from the first display to the second display corresponds to a closing operation of a folder type mobile communication terminal.

19. The method of claim 11, wherein a list of the one or more tasks can be displayed on the second display.

20. The method of claim 11, further comprising displaying a specific task on the first display if a command for a display return from the second display to the first display is received, wherein the specific task was a Latest Recently Used (LRU) task prior to the display conversion.

21. The method of claim 20, wherein the display return from the second display to the first display corresponds to an opening operation of a folder type mobile communication terminal.

22. The method of claim 20, wherein during the display return, the one or more tasks have the same execution order as the execution order prior to the display conversion.
