Mention of ETC in CNET CES 3D FAQ

Do 3D TVs use more power?

No manufacturer we asked would say one way or another, although two other sources (the head of USC’s Entertainment Technology Center, as well as Bruce Berkoff of the LCD TV association) said they do not. On the other hand, it’s true that the active LC shutter glasses effectively block half of the light arriving from the screen, and the lenses are not entirely transparent to begin with, so logically a TV displaying a 3D image could use more power than the same TV to produce a 2D image of equivalent brightness. But it’s just too early to know until we can test one.
