Order of LEDs on the Side

The movement to replace the traditional fluorescent (CCFL) backlighting for LCD displays with LEDs has become a flood. Sony’s 2011 lineup is dominated by LED-lit LCDs. While the line-topping XBR-HX929 sets have full-array LED backlighting with local dimming, the remainder position their LEDs just beyond the edges of the screen. Aside from lower power consumption compared with CCFL blacklights, LED backlights of either type offer another benefit: They can adjust rapidly in accordance with the changing signal. Edge-lit LED backlights have two primary advantages to manufacturers over the full-array approach that has made them the more widely used. One is lower cost; the other is the ability, at least in some HDTVs, to shrink the depth of the panel to something that seems to approach that of a credit card.

Vizio steps up with the first passive 3DTV, but will the world take it sitting down?

Since the advent of 3D for the home, the specter of pricey active shutter glasses that cost as much as $150 each has hung over the technology like a dark cloud. Many potential buyers are put off by the prospect of buying enough glasses to outfit the whole family, not to mention the houseful of friends who’ve come over to watch Hoodwinked Too! Hood vs. Evil in 3D. (Yes, Virginia, there is a Hoodwinked! sequel in the pipeline. Not many remember that the computer-animated Hoodwinked! was produced in 3D, probably because not many remember Hoodwinked! at all.)

3D Gets Big

It seems like only yesterday that I reviewed Sony’s VPL-VW85 projector, but it was a year and a half ago (Home Theater, November 2009). Sony launches a new flagship home theater projector every year at the September CEDIA EXPO, and 2010 was no exception.

DLP Hangs Tough

Digital Light Processing (DLP) may have jump-started the whole digital display revolution in the late 1990s, but to the consumer, the technology might look like it’s fallen on hard times. Only one major HDTV manufacturer—Mitsubishi—now makes DLP rear projectors. And since DLP is a projection technology, there are no DLP sets that can project an image across a distance of 2 inches or less to compete with today’s popular flat panels.
