Really? How does that work? I'm interested in the cost and models of these TV's and if they are available to purchase.
Q: What's the difference between "active" and "passive" 3D TVs?
A: The first wave of 3D TVs released in 2010 were all active 3D TVs that used shutter-type active 3D glasses. In 2011, most 3D TVs are still active, but some TV makers have also introduced passive 3D models.
Active 3D — Active 3D TVs require viewers to wear battery-powered active shutter glasses to see the 3D effects. These shutter glasses feature LCD lenses that alternately block the view of the right eye and left eye in response to sync signals beamed wirelessly from the TV. Active 3D TVs provide full 1080p picture resolution for each eye. However, the glasses are expensive and usually bulkier than passive glasses, and some viewers are bothered by their high-speed flickering.
Passive 3D — Passive 3D TVs provide a 3D experience that's very similar to watching a 3D movie in a theater. For passive 3D TVs, the screen is doing almost all of the work. Not only are two video images being displayed, but there's also a special screen coating that works with the polarizing passive glasses to create the 3D effect. Passive 3D glasses are lightweight and inexpensive and require no batteries — they're virtually identical to the 3D glasses handed out in movie theaters. Passive 3D provides a picture that's crisp and bright and free of any traces of flicker. Passive 3D technology is less sensitive to a viewer's viewing angle or head movement, which makes it easier for several people to enjoy convincing 3D effects.
Here's an article about a head to head study of active vs passive 3D. It has a few models listed in it.

And here's the actual study:
