Abstract

In some embodiments a user interface is adapted to monitor user inputs and one or more controllers are adapted to modify backlight segment brightness and/or image pixel values of a segmented backlight display in response to the monitored user inputs. Other embodiments are described and claimed.

Claims

1. A method comprising:

monitoring user inputs;

modifying backlight segment brightness and/or image pixel values of a segmented backlight display in response to the monitoring.

2. The method of claim 1, further comprising translating the user inputs to control commands, wherein the modifying is in response to the control commands.

3. The method of claim 1, further comprising lighting only display segments aligned with a focus window.

4. The method of claim 3, further comprising dimming or turning off display segments outside the focus window.

5. The method of claim 3, further comprising darkening or making black pixels outside the focus window.

6. The method of claim 3, further comprising adjusting a size and/or position of the focus window.

7. The method of claim 3, further comprising lighting the entire segmented backlight display in response to a user input corresponding to an area that is outside the focus area.

8. The method of claim 3, further comprising changing a background window to the focus area in response to a user input corresponding to the background window.

9. The method of claim 1, further comprising lighting only display segments aligned with a user defined region.

10. The method of claim 9, further comprising allowing the user to arrange more than one window inside the user defined region.

11. The method of claim 9, further comprising resizing and/or repositioning the user defined region.

12. An apparatus comprising:

a user interface adapted to monitor user inputs;

one or more controllers adapted to modify backlight segment brightness and/or image pixel values of a segmented backlight display in response to the monitored user inputs.

13. The apparatus of claim 12, wherein the user interface is adapted to translate the user inputs to control commands, the one or more controllers adapted to modify the backlight segment brightness and/or the image pixel values in response to the control commands.

14. The apparatus of claim 12, the one or more controllers including a backlight controller adapted to modify the backlight segment brightness and including a pixel controller adapted to modify the image pixel values.

15. The apparatus of claim 12, the one or more controllers adapted to light only display segments aligned with a focus window.

16. The apparatus of claim 15, the one or more controllers adapted to dim or turn off display segments outside the focus window.

17. The apparatus of claim 15, the one or more controllers adapted to darken or make black pixels outside the focus window.

18. The apparatus of claim 15, the one or more controllers adapted to adjust a size and/or position of the focus window.

19. The apparatus of claim 15, the one or more controllers adapted to light the entire segmented backlight display in response to a user input corresponding to an area that is outside the focus area.

20. The apparatus of claim 15, the one or more controllers adapted to change a background window to the focus area in response to a user input corresponding to the background window.

21. The apparatus of claim 12, the one or more controllers adapted to light only display segments aligned with a user defined region.

22. The apparatus of claim 21, the one or more controllers adapted to allow the user to arrange more than one window inside the user defined region.

23. The apparatus of claim 21, the one or more controllers adapted to resize and/or reposition the user defined region.
