TCO study compares active and passive 3DTV glasses, doesn't really favor one over the other
The debate over active and passive 3DTV glasses has, for the most part, been riddled with biased claims (and more than a little mudslinging) from TV manufacturers on both sides of the aisle. Now, however, an independent study from TCO Development has finally shed some light on how the two glasses can actually affect a user's viewing experience -- and yes, there are some differences. When researchers tilted the passive, film pattern retarder (FPR) above or below a vertical viewing angle of 15-degrees, 3D images tended to bleed into one another at a higher rate. Active glasses, meanwhile, transmitted white images at a luminance that was three times lower than what FPR-equipped shades delivered. But because passive 3D glasses display images at different polarizations for each eye, they don't offer as much vertical resolution as their active counterparts. Unfortunately, TCO didn't look into how each pair of glasses affects a viewer's health and comfort -- which, for most of us, would probably be the deciding factor. But as soon as it does, expect either Panasonic or LG to jump all over the results. Dive into the full PR after the break.
