Abstract

A mobile terminal capable of allowing a user to rapidly and easily recognize a list of multi-tasks being executed is provided. The mobile terminal includes one or more bodies, an input unit performing a key input or a touch input, a display unit displaying a task execution screen and a controller displaying a list of tasks being executed when the mobile terminal is in a preset operation mode set by operating the body or the input unit.

Claims

1. A method for controlling a screen of a mobile terminal, the method comprising:

executing one or more tasks; and

displaying a list of the one or more tasks being executed when the mobile terminal is in a preset operation mode.

2. The method of claim 1, wherein the task list is displayed when the mobile terminal is converted from a standby state to an idle state.

3. The method of claim 1, wherein the task list is displayed when the mobile terminal is converted from an idle state to a standby state.

4. The method of claim 1, wherein the task list is displayed upon receiving one of a predetermined key input and a predetermined touch input when the mobile terminal is in one of a standby state and an idle state.

5. The method of claim 1, wherein the task list is displayed when another task exists after finishing the one or more tasks being executed.

6. The method of claim 1, wherein displaying the task list comprises displaying an icon related to each of the one or more tasks, each icon comprising one of a moving image and a stationary image.

7. The method of claim 6, wherein the icon related to each of the one or more tasks comprises an image indicating one of contents and a function of information included in the corresponding task.

8. The method of claim 1, wherein displaying the task list comprises displaying an indicator on a predetermined region of a display unit when a number of tasks being executed is at least two.

9. The method of claim 1, wherein the task list is displayed on a predetermined region of a display unit in a tab form.

10. The method of claim 1, wherein the task list is displayed on a predetermined region of a display unit in one of a scroll manner and a pop up manner.

11. A mobile terminal, comprising:

one or more bodies;

an input unit performing at least one of a key input and a touch input;

a display unit displaying a task execution screen; and

a controller controlling the display unit to display a list of tasks being executed when the mobile terminal is in a preset operation mode according to manipulation of the one or more bodies and the input unit.

12. The mobile terminal of claim 11, wherein the controller displays the task list when the mobile terminal is converted from a standby state to an idle state.

13. The mobile terminal of claim 11, wherein the controller displays the task list when the mobile terminal is converted from an idle state to a standby state.

14. The mobile terminal of claim 11, wherein the controller displays the task list upon receipt of one of a predetermined key input and a predetermined touch input when the mobile terminal is in one of a standby state and an idle state.

15. The mobile terminal of claim 11, further comprising a memory unit storing an icon corresponding to each of the tasks being executed, the icon comprising one of a moving image and a stationary image.

16. The mobile terminal of claim 11, wherein the controller displays an indicator on a predetermined region of the display unit when a number of tasks being executed is at least two.

17. The mobile terminal of claim 11, wherein the controller displays the task list on a predetermined region of the display unit in a tab form.

18. The mobile terminal of claim 11, wherein the controller displays the task list on the display unit in one of a scroll manner and a pop up manner.

19. The mobile terminal of claim 11, wherein the controller deletes the task list when a predetermined time lapses after the mobile terminal is converted from a standby state to an idle state.

20. The mobile terminal of claim 11, wherein the controller deletes the task list upon receipt of one of a predetermined key input and a predetermined touch input when the mobile terminal is in a standby state.

21. The mobile terminal of claim 11, wherein the controller displays and deletes the task in a toggle manner upon receipt of the same one of a predetermined key input and a predetermined touch input.

22. The mobile terminal of claim 11, further comprising a memory unit and wherein the controller stores information related to each of the tasks being executed in the memory and continuously stores the information related to any of the tasks being executed whose execution is not finished.
