Steve: Hi, I'm Steve, and I'm here in the Crutchfield studio to show you Sony's top-of-the-line XBR8 series of LCD HDTVs. This is the 46-inch model, and it's a beautiful TV, as you can see, with this floating glass design that's distinctive to Sony's XBR line.

But of course, the most exciting stuff is inside the TV. XBR8 TVs use Sony's TRILUMINOUS LED backlighting system. It's more efficient than the fluorescent backlighting used by most LCD TVs, and it can deliver a more vibrant, lifelike picture.

Now, most other backlighting systems rely on a combination of white lights and color filters. But the TRILUMINOUS system actually uses pure red, green, and blue LEDs to produce the XBR8's picture. That's why XBR8s can produce 100% of the broadcast TV color range, which isn't something many other HDTVs can do. You'll see colors that look deeper, purer, and more accurate.

TRILUMINOUS lighting also gives XBR8 TVs an excellent contrast ratio. That is, the ability to display very bright whites and very dark blacks simultaneously. You see, the XBR8 doesn't depend on a single main backlight that's always on. Instead, it uses clusters of LEDs to light the screen. It can turn off the LEDs in an area of shadow, but leave them on for bright sunlight. That way, even scenes with both bright and dark areas are displayed accurately — something that's usually challenging for LCD TVs.

So that's the scoop on Sony's XBR8 LCD HDTVs. For more info, visit crutchfield.com/SonyXBR8.
