Last week's Finetech Japan 2010 expo allowed display manufacturers to show and tell each other about their latest innovations and advancements. One of the unquestioned highlights was NewSight's implementation of parallax barrier technology on displays up to 70 inches in size. The company is claiming its demo unit as the world's largest glasses-free 3D screen, but regrettably deprives us of any further details. All we're told is that the parallax barrier is "affixed to commercial-grade" LCDs, which suggests to us that perhaps the technique and hardware could be applied atop your favorite brand's existent 2D models. Of course, that'd only matter if these displays deliver a manifestly better picture and experience than what we have now, but it's looking like we'll have to wait a little bit longer to find out.
