Systems and methods for controlling operation of a backlight for a display panel

1. A method of controlling operation of a display unit of an electronic device, comprising:

generating a graphical display signal by a display controller;

interpreting the graphical display signal by the display unit to display a content of the graphical display signal on a display panel of the display unit;

comparing the content of the graphical display signal to a known graphical data pattern wherein the known graphical data pattern comprises data entailing a specific graphic, word, or image; and

operating the display unit in accordance to an operating parameter corresponding to the known graphical data pattern if the known graphical data pattern is detected in the display signal while the electronic device is in a network standby mode;

wherein operating the display unit according to an operating parameter includes turning on a backlight of the display unit, turning off the backlight of the display unit, or adjusting a brightness level of the backlight of the display unit.

2. The method of claim 1 , wherein the graphical display signal comprises data pertaining to a plurality of individual frames for the content, and the comparing comprises comparing one or more the frames to the known graphical data pattern.

3. The method of claim 2 , wherein the operating occurs only if a preset number of the frames in successive order contain the known graphical data pattern.

4. The method of claim 1 , wherein the operating ceases for portions of the graphical display signal in which the known graphical data pattern is not detected.

5. The method of claim 1 , wherein operating the display unit in accordance to the operating parameter comprises turning the backlight on for portions of the display signal in which the graphical display signal contains any non-zero values.

6. The method of claim 1 , wherein the operating comprises increasing the brightness level of the backlight for portions of the graphical display signal in which the known graphical data pattern is detected.

7. The method of claim 1 , wherein the comparing is performed by the display controller and the operating is performed by a product controller.

8. The method of claim 7 , wherein detection logic of the display controller performs the comparing, the method further comprising communicating results of the comparing to the product controller.

9. The method of claim 8 , wherein the communicating comprises modifying a system file of an operating system and reading the system file by the product controller, the system file comprising instructions pertaining to the operating parameter.

10. A display unit, comprising:

a display panel configured to interpret a graphical display signal received by the display unit from a display controller, and to display a content of the display signal across the entire display panel; and

a backlight configured to emit light through the display panel and to operate at a brightness level corresponding to a known graphical data pattern if the known graphical data pattern is detected in the content of the entire display panel while the electronic device is in a network standby mode and wherein the known graphical data pattern comprises data entailing a specific graphic, word, or image.

11. An electronic display control system, comprising:

a display controller configured to generate a graphical display signal;

a display unit comprising a display panel and a backlight, the display unit configured to interpret the graphical display signal and to display a content of the graphical display signal on the display panel;

detection logic configured to compare the graphical display signal to a known graphical data pattern wherein the known graphical data pattern comprises data entailing a specific graphic, word, or image; and

a product controller configured to control operation of the backlight in accordance with an operating parameter corresponding to the known graphical data pattern if the known graphical data pattern is detected by the detection logic in the graphical display signal while the electronic device is in a network standby mode;

wherein operation of the backlight in accordance with the operating parameter includes turning on the backlight, turning off the backlight, or adjusting a brightness level of the backlight.

12. The electronic display control system of claim 11 , wherein the product controller is configured to turn the backlight off for portions of the graphical display signal in which the known graphical data pattern is detected.

13. The electronic display control system of claim 11 , wherein the display panel is a liquid crystal display panel.

14. An electronic device comprising the control system of claim 11 .

15. The electronic device of claim 14 , wherein the electronic device comprises a stereo or loudspeaker system.
