Abstract :
The addition of a segmented backlight enables a significant contrast improvement and power savings for LCD panels. Determining the proper backlight drive values and adapting the video accordingly is far from trivial. This paper will focus on an efficient algorithm and architecture enabling the high dynamic range experience.
