Abstract

A display management method and system of a mobile terminal that provides the user with indications of the currently running applications and activation and deactivation progresses of the applications. A first execution screen of a first application is displayed, and an input signal is detected for activating a second application. A second execution screen is displayed corresponding to the second application in response to the input signal. The second execution screen includes at least one of a first intermediate image obtained by downsizing an image contained within the first execution screen, a second intermediate image obtained by downsizing an image contained within the second execution screen, and a task window containing at least the downsized first and second intermediate images in a sequential order.

Claims

1. A method of displaying an activation screen switching process of a mobile terminal, comprising:

displaying on a display unit a first execution screen of a first application;

in response to sensing a tilt of the mobile terminal, determining that the sensed tilt comprises a quick application switch command for displaying a second execution screen corresponding to a second application;

replacing the first execution screen on the display unit with a first intermediate screen having an image obtained by downsizing an image presented in the first execution screen in which the first intermediate screen displays at a reduced size an entirety of the first execution screen;

replacing the first intermediate screen with a second intermediate screen having an image obtained by downsizing an image presented in the second execution screen in which the second intermediate screen displays at a reduced size only an entirety of the second execution screen for a predetermined time interval;

replacing the second intermediate screen with the second execution screen of the second application;

obtaining a zoom-in effect by displaying an intermediate image of the second intermediate screen showing a reduced size of a single screen image for the predetermined time interval, then displaying a second application screen displaying a full screen image in sequence;

presenting a task window having thumbnail images of at least the first and second intermediate images in a sequential order on the display after erasing the first execution screen;

presenting the task window on the display after erasing the first execution screen;

erasing the task window after a predetermined time interval; and

presenting the second execution screen after erasing the task window.

2. The method of claim 1, wherein the thumbnail images are smaller in size than the first and second intermediate images.

3. The method of claim 1, wherein replacing the second intermediate screen further comprises:

presenting an intermediate task window image which is identical with the first intermediate image in size before presenting the task window for the predetermined time interval; and

presenting the intermediate task window image after erasing the intermediate task window.

4. A mobile terminal comprising:

a display unit which displays an execution screen of an activated application;

a tilting sensor for sensing a tilt of the mobile terminal; and

a control unit which controls processing to display a series of images to show a progress of switching between a first application running in foreground and a second application running in background selected in response to an input signal,

wherein the control unit controls for replacing a first execution screen on a display unit with a first intermediate screen having an image obtained by downsizing an image presented in the first execution screen in which the first intermediate screen displays at a reduced size an entirety of the first execution screen and replacing the first intermediate screen with a second intermediate screen having an image obtained by downsizing an image presented in a second execution screen in which the second intermediate screen displays at a reduced size only an entirety of the second execution screen for a predetermined time interval, and replacing the second intermediate screen with the second execution screen of the second application, and

wherein the control unit is further configured to;

determine that a sensed tilt by the tilting sensor comprises a quick application switch command to display the second execution screen corresponding to the second application; and

obtain a zoom-in effect by controlling display of the second intermediate screen showing only a reduced size of a single screen image for the predetermined time interval, then displaying the second application screen displaying only a full screen image in sequence.

5. The mobile terminal of claim 4, wherein the display unit presents the first intermediate image, a task window having thumbnail images of at least the first and second intermediate images in a sequential order, and the second intermediate image in series for the predetermined time interval respectively, and thereafter displays the second execution screen.

6. The mobile terminal of claim 5, wherein the display unit presents the first intermediate image along with a background image around the first intermediate image and moves the first intermediate image to an edge of the display to disappear from the display.

7. The mobile terminal of claim 5, wherein the display unit moves the second intermediate image from an edge of the display to a center of the display, presents the second intermediate image along with a background image around the second intermediate image, and erases the second intermediate image after the second intermediate image remains at the center of the display for the predetermined time interval.

8. The mobile terminal of claim 4, wherein the display unit erases the first execution screen from the display, presents a task window on the display after erasing the first execution screen, erases the task window after a predetermined time interval, and presents the second execution screen after erasing the task window.

9. The mobile terminal of claim 8, wherein one or more thumbnail images are smaller in size than the first and second intermediate images.

10. The mobile terminal of claim 8, wherein the display unit presents an intermediate task window image which is identical with the first intermediate image in size before presenting the task window for the predetermined time interval and the intermediate task window image after erasing the task window.

11. The mobile terminal of claim 4, wherein the display unit presents the first intermediate image for a predetermined time interval, the second intermediate image for the predetermined interval, and the second execution screen respectively.

12. The mobile terminal of claim 11, wherein the display unit presents the first intermediate image along with a background image around the first intermediate image, moves the first intermediate image to an edge of the display to disappear from the display, moves the second intermediate image from an edge of the display to a center of the display, presents the second intermediate image along with the background image around the second intermediate image, and erases the second intermediate image from the display after the second intermediate image remains at the center of the display for the predetermined time interval.

13. The mobile terminal of claim 4, further comprising a touch panel which presents a key map for inputting the input signal and senses a touch event designated for generating the input signal on the key map.

14. A method of displaying an activation screen switching process of a user device, comprising:

displaying on a display unit a first execution screen of a first application;

receiving an input signal;

replacing the first execution screen on the display unit with a task window comprising a first image obtained by downsizing an image presented in the first execution screen and a second image obtained by downsizing an image in response to a second application in a running state,

wherein the downsized image is an intermediate image larger than a thumbnail and in which the intermediate image is displayed at a reduced size an entirety of the first execution screen;

obtaining a zoom-in effect by displaying the intermediate image, second application screen showing only a reduced size of a single screen image for a predetermined time interval showing only the reduced size an entirety of the first execution screen for a predetermined time interval, then displaying a second application screen displaying only and a full screen image in sequence; and
