‪Glasses-‬F‪ree 3D TV ‬
Added Jul 19, 2012 | Rate View top rated
Despite impressive recent advances, holographic television - which would present images that vary with varying perspectives - probably remains some distance in the future. The MIT Media Lab's Camera Culture group offers a new approach to multiple-perspective, glasses-free 3D that could prove much more practical in the short term. Instead of the complex hardware required to produce holograms, the Media Lab system uses several layers of liquid-crystal displays (LCDs). To produce a convincing 3D illusion, the displays would need to refresh at a rate of about 360 times a second, or 360 hertz. Such displays may not be far off - LCD TVs that boast 240-hertz refresh rates have already appeared on the market, just a few years after 120-hertz TVs made their debut.
