Abstract

A device for controlling a screen according to data loading in a terminal is provided. The device includes a display whose screen brightness value is changed step by step while data is being loaded, and a controller configured to control to change, if data information is requested, a screen brightness value of the display step by step according to progress of data loading, and to control to display the data being loaded, on the display whose screen brightness value is changed step by step.

Claims

1. A device for controlling a screen according to data loading in a terminal, the device comprising:

a display whose screen brightness value is changed step by step while data is being loaded; and

a controller configured to control to change, if data information is requested, a screen brightness value of the display step by step according to progress of data loading, and to control to display the data being loaded, on the display whose screen brightness value is changed step by step.

2. The device of claim 1, wherein, if the data information is requested, the controller is configured to determine whether a ‘

display a screen that is adjusted according to a progress of data loading’

option is set, and controls to change a screen brightness value of the display step by step according to the progress of data loading, if the ‘

display a screen that is adjusted according to a progress of data loading’

option is set.

3. The device of claim 1, wherein, if the data information is requested on the display whose screen brightness value is set to a default screen brightness value, the controller is configured to control to change the screen brightness value to zero (0), and increase the screen brightness value of the display step by step according to the progress of the data loading while displaying the data being loaded.

4. The device of claim 3, wherein, upon completion of the data loading, the controller is configured to control to change the screen brightness value of the display to the default screen brightness value, and to display the completely loaded data on the display.

5. The device of claim 3, wherein, if a touch action occurs on the display while the data is being loaded, the controller is configured to control to change the screen brightness value of the display to the default screen brightness value, and to display the data being loaded.

6. The device of claim 1, wherein, while the data is being loaded, the controller is configured to control to display a progress bar indicating the progress of data loading, in a predetermined area on the display.

7. The device of claim 1, wherein the controller is configured to control to change the screen brightness value of the display step by step according to the progress of data loading by controlling a backlight unit while the data is being loaded.

8. The device of claim 1, wherein the controller is configured to control to change the screen brightness value of the display step by step according to the progress of data loading by adjusting predetermined pixel values applied to the screen of the display step by step while the data is being loaded.

9. The device of claim 1, wherein, if the data information is requested, the controller is configured to determine whether a ‘

display data after completion of data loading’

option is set, control to change the screen brightness value to zero (0), if the ‘

display data after completion of data loading’

option is set, and control to display the progress of data loading with a User Interface (UI) on the display whose screen brightness value is changed to zero (0).

10. The device of claim 9, wherein the controller is configured to control to display the progress of data loading in a text or an image.

11. The device of claim 9, wherein, if the data loading is completed, the controller is configured to control to change the screen brightness value of the display to a default screen brightness value, and to display the completely loaded data on the display.

12. The device of claim 9, wherein, if a touch action occurs on the display while the data is being loaded, the controller is configured to control to change the screen brightness value of the display to a default screen brightness value, and to display the data being loaded.

13. The device of claim 9, wherein while the data is being loaded, the controller controls to display a progress bar indicating the progress of data loading, in a predetermined area on the display.

14. A method for controlling a screen according to data loading in a terminal, the method comprising:

changing a screen brightness value of a display step by step according to progress of data loading, if data information is requested; and

displaying the data being loaded, on the display whose screen brightness value is changed step by step.

15. The method of claim 14, wherein the changing a screen brightness value comprises:

determining whether a ‘

display a screen that is adjusted according to a progress of data loading’

option is set, if the data information is requested; and

changing a screen brightness value of the display step by step according to the progress of data loading, if the ‘

display a screen that is adjusted according to a progress of data loading’

option is set.

16. The method of claim 14, wherein the changing of the screen brightness value comprises:

changing the screen brightness value to zero (0), if the data information is requested on the display whose screen brightness value is set to a default screen brightness value; and

increasing the screen brightness value of the display step by step according to the progress of data loading while displaying the data being loaded.

17. The method of claim 14, wherein the changing of the screen brightness value comprises:

changing the screen brightness value of the display step by step according to the progress of data loading by controlling a backlight unit while the data is being loaded.

18. The method of claim 14, wherein the changing of the screen brightness value comprises:

changing the screen brightness value of the display step by step according to the progress of data loading by adjusting predetermined pixel values applied to the screen of the display step by step while the data is being loaded.

19. The method of claim 14, further comprising:

changing, upon completion of the data loading, the screen brightness value of the display to a default screen brightness value; and

displaying the completely loaded data on the display whose screen brightness value is changed to the default screen brightness value.

20. The method of claim 14, further comprising:

changing the screen brightness value of the display to a default screen brightness value, if a touch action occurs on the display while the data is being loaded; and

displaying the data being loaded, on the display whose screen brightness value is changed to the default screen brightness value.

21. The method of claim 14, further comprising:

displaying a progress bar indicating the progress of data loading, in a predetermined area on the display, while the data is being loaded.

22. The method of claim 14, further comprising:

determining whether a ‘

display data after completion of data loading’

option is set, if the data information is requested;

changing the screen brightness value to zero (0), if the ‘

display data after completion of data loading’

option is set; and

displaying the progress of data loading with a User Interface (UI) on the display whose screen brightness value is changed to zero (0).

23. The method of claim 22, wherein the progress of data loading is displayed in a text or an image.

24. The method of claim 22, further comprising:

changing the screen brightness value of the display to a default screen brightness value, if the data loading is completed; and

displaying the completely loaded data on the display whose screen brightness value is changed to the default screen brightness value.

25. The method of claim 22, further comprising:

changing the screen brightness value of the display to a default screen brightness value, if a touch action occurs on the display while the data is being loaded; and

displaying the data being loaded, on the display whose screen brightness value is changed to the default screen brightness value.

26. The method of claim 22, further comprising:

displaying a progress bar indicating the progress of data loading, in a predetermined area on the display, while the data is being loaded.
