World's Largest (200 Inches Diagonal) Glasses-Free 3D Display Unveiled in Japan

While the world's most important consumer electronics manufacturers are struggling to come up with all sorts of 3D viewing solutions, it seems that the future of public display is also 3D, but glasses-free, a Japanese research institute unveiling what really seems to be the world's largest display solution of this type ever built.

So, according to AkihabaraNews, Japanese institute NiCT (National Institute of Information and Communications Technology) announced a while ago a glasses-free display solution with a diagonal size of no less than 200 inches, which virtually makes it the world's largest.

The Universal Media Research Center in Keihanna Research Labs (Kyoto, Japan), the NiCT branch that came up with this development, is actively conducting research on ultra-realistic communication systems using natural 3D images without special glasses, but in order to attain some very good large-scale results, it was forced to come up with a solution to the problem of “Strip Noise” between parallax images.

In order to mitigate this rather serious issue, researchers decided to employ LED light sources in order to compensate and balance colors and brightness between the projector and the surface, the overall result being a large-size image delivering a good level of quality and uniformity throughout its entire area.

Moreover, for the display, they've used a special diffuser film and a condenser lens, enabling it to ultimately display more than 50 parallax images at any given moment.

Researchers from NiCT also have some pretty big plans for the future, as they intend to push the number of parallax images up to 200, as well as increase the overall size of the screen, ultimately leading to the development of digital-signage or cinema theater-grade displays (we're really looking forward to seeing the first glasses-free 3D cinemas make an appearance, but it's quite clear that it will be some time before such solutions become available).
