What is active and passive 3D?

Wear 3D glasses watch 3D television

CES attendees wear 3-D glasses as they watch a 3-D television in the Panasonic booth at the 2010
International Consumer Electronics Show at the Las Vegas Hilton January 7, 2010 in Las Vegas.
Many of us were blown away by the 3-D visual effects of "Avatar" when we saw it in theaters. Now, that same experience is headed to your home theater. Three-D is considered by many to be the "next big thing" in visual entertainment, so a 3-D-capable television is a great gift idea this season.
Three-D TVs can come with either special glasses like you get in the theaters, known as "passive 3-D," or they can include battery-powered liquid crystal shutters that generate the 3-D effect -- this is called "active 3-D." Active 3-D was the most common type when these TVs launched last year, but lately passive 3-D TVs are more common. Passive glasses are less expensive as well, but the quality isn't quite as a good.

Important Note:

It's important to note that 3-D hasn't become mainstream quite yet. Three-D Blu-Ray DVDs are rare and 3-D TV channels are even rarer. However, 3-D video games are catching on quickly, so a TV that can handle those effects might be great for gamers. Right now, it's best to think of 3-D as just one of the many features offered on a modern TV, not as the main reason to purchase a new set. Still, having a 3-D TV means you'll be ready for the exciting new features that might be available in the near future.
