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 folder type mobile communication terminal capable of displaying a task executed thereon and configured to be in a folded or open configuration according to a position of a folder of the mobile communication terminal, 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 responsive to a display conversion from the first display to the second display upon folding of the mobile communication terminal to be in the folded configuration; and

a controller operationally connected with the first display and the second display,

wherein the controller is configured to display on the second display a highest priority task among the one or more tasks simultaneously being executed responsive to the display conversion, and

wherein the controller is further configured to re-display on the first display a task that was displayed on the first display prior to the display conversion responsive to a display return from the second display to the first display upon opening of the mobile communication terminal to be in the open configuration.

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 a list of the one or more tasks is displayed on the second display.

16. The mobile communication terminal of claim 1, wherein only one of the first display and the second display is active according to the folded or open configuration.

17. The mobile communication terminal of claim 16, wherein the first display is active in the open configuration.

18. The mobile communication terminal of claim 16, wherein the second display is active in the folded configuration.

8. A method for displaying a task executed on a folder type mobile communication terminal that is configured to be in a folded or open configuration according to a position of a folder of the mobile communication terminal, the method comprising:

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

receiving a command for a display conversion from the first display to a second display of the mobile communication terminal, the command for the display conversion generated when a configuration of the mobile communication terminal is switched from the open configuration into the folded configuration;

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

displaying a specific task on the first display in response to a command for a display return from the second display to the first display, the command for the display return generated when the configuration of the mobile communication terminal is switched from the closed configuration into the open configuration, wherein the specific task is a Latest Recently Used (LRU) task that was displayed on the first display prior to the display conversion.

wherein the one or more tasks have the same execution order as an execution order prior to the display conversion upon the display return.

9. The method of claim 8, further comprising:

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

determining the highest priority task based on the comparison.

10. The method of claim 8, wherein the highest priority task is a task related to a communication function.

11. The method of claim 8, wherein the highest priority task is a task related to a sound output function.

12. The method of claim 8, further comprising:

changing the highest priority task into the Latest Recently Used (LRU) task if the highest priority task is not the LRU task.

13. The method of claim 8, wherein a default task is displayed if the highest priority task does not exist.

14. The method of claim 8, 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 on the second display the highest priority task.

15. The method of claim 8, further comprising:

displaying a list of the one or more tasks on the second display.

19. The method of claim 8, wherein only one of the first display and the second display is active according to the folded or open configuration.

20. The method of claim 19, wherein the first display is active in the open configuration.

21. The method of claim 19, wherein the second display is active in the folded configuration.
