Abstract

An apparatus and method are provided for controlling the display of a screen in an electronic device that supports multitasking. In the method, the apparatus displays first and second application execution screens on first and second areas of a screen, respectively. The first and second areas are distinct from each other. When an event for executing a third application is detected, the apparatus displays the second application execution screen on the first area and also displays a third application execution screen on the second area in response to the detected event. When execution of the third application is terminated, the apparatus displays the first application execution screen on the first area and also displays the second application execution screen on the second area.

Claims

1. An electronic device comprising:

a display panel configured to display respective application execution screens on a first area and a second area of a display screen, the first and second areas being distinct from each other; and

a control circuit configured to;

display a second application execution screen on the first area and to display a third application execution screen on the second area when an event for executing a third application is detected while a first application execution screen is displayed on the first area and the second application execution screen is displayed on the second area,

display the first application execution screen on the first area and to display the second application execution screen on the second area when execution of the third application is terminated,

determine an attribute of the third application when the third application is executed in response to the event,

display the second application execution screen on the first area and to display the third application execution screen on the second area when the attribute of the third application is set to display the third application execution screen on the second area, and

transparently display a portion of at least one item for controlling the third application execution screen overlapping onto the second application execution screen displayed in the second area when the attribute of the third application is set to display the at least one item on the second area,

wherein the portion of the at least one item for controlling the third application execution screen is transparently displayed overlapping onto the second application execution screen while the third application execution screen is simultaneously being displayed in the first area in place of the first application execution screen.

2. The electronic device of claim 1, wherein the first area is located at an upper part of the screen, and the second area is located at a lower part of the screen.

3. The electronic device of claim 1, wherein the control circuit is further configured to display the third application execution screen on the first area when the attribute of the third application is set to display the at least one item for controlling the third application execution screen on the second area.

4. The electronic device of claim 3, wherein the control circuit is further configured to remove the at least one item from the second area and display the first application execution screen on the first area when the execution of the third application is terminated.

5. The electronic device of claim 1, wherein the control circuit is further configured to display one of a specific application selected by a user, a predefined default application, a recently executed application, and a frequently executed application in the form of at least one of a widget, a shortcut, and an icon on the first application execution screen.

6. The electronic device of claim 1, wherein the attribute of the third application is one of information which is set to display the third application execution screen on the second area, and information which is set to display the at least one item for controlling the third application execution screen on the second area, and

wherein the control circuit is further configured to set the attribute of the third application in response to a user input.

7. The electronic device of claim 1, wherein the first and second areas are divided logically or physically within the screen.

8. The electronic device of claim 1, wherein the event for executing the third application is one of a call reception, a music playback, a camera activation, a notification reception, and a message reception.

9. A method for controlling a screen display in an electronic device, the method comprising:

displaying first and second application execution screens on first and second areas of a screen, respectively, wherein the first and second areas are distinct from each other;

detecting an event for executing a third application;

displaying the second application execution screen on the first area and displaying a third application execution screen on the second area in response to the detected event;

displaying the first application execution screen on the first area and displaying the second application execution screen on the second area when execution of the third application is terminated;

determining an attribute of the third application when the third application is executed in response to the event;

displaying the second application execution screen on the first area and displaying the third application execution screen on the second area when the attribute of the third application is set to display the third application execution screen on the second area; and

transparently displaying a portion of at least one item for controlling the third application execution screen overlapping onto the second application execution screen displayed in the second area when the attribute of the third application is set to display the at least one item on the second area,

wherein the portion of the at least one item for controlling the third application execution screen is transparently displayed overlapping onto the second application execution screen while the third application execution screen is simultaneously being displayed in the first area in place of the first application execution screen.

10. The method of claim 9, wherein the first area is located at an upper part of the screen, and the second area is located at a lower part of the screen.

11. The method of claim 9, further comprising:

displaying the third application execution screen on the first area when the attribute of the third application is set to display the at least one item on the second area.

12. The method of claim 11, further comprising:

removing the at least one item from the second area and displaying the first application execution screen on the first area when the execution of the third application is terminated.

13. The method of claim 9, wherein displaying the first application execution screen on the first area includes displaying one of a specific application selected by a user, a predefined default application, a recently executed application, and a frequently executed application in the form of at least one of a widget, a shortcut, and an icon on the first application execution screen.

14. The method of claim 9, wherein the first and second application execution screens are displayed at the same layer of the screen.

15. The method of claim 9, wherein the attribute of the third application is one of information which is set to display the third application execution screen on the second area, and information which is set to display the at least one item for controlling the third application execution screen on the second area, and

wherein the attribute of the third application is set in response to a user input.

16. The method of claim 9, wherein the event for executing the third application is one of a call reception, a music playback, a camera activation, a notification reception, and a message reception.
