In place of a conventional fluorescent backlight, the UN46B7000 uses a series of LEDs. LED backlighting dramatically improves picture contrast, expanding the range of gray tones from absolute black to brilliant white. It also increases the number of available colors — you'll primarily notice deeper reds and greens. Images have tremendous punch and impact, and colors look more nuanced and natural. An LED backlight also doesn't require as much power. In fact, Samsung's 2009 LED HDTVs consume up to 40% less power than last year's conventional LCD sets.
