Japan shows off world's largest glasses-free 3D display

Japan's National Institute of Information and Communications and JVC Kenwood recently demonstrated a 200-inch glasses-free 3D display that they touted as the world's largest auto-stereoscopic 3D screen. Aside from the enormous size, the system offers a full-HD resolution with 57 effective viewing angles. Hardware-wise, 57 projectors were deployed to render the 3D visuals, and these have to be individually tuned to maintain a uniform brightness and color consistency. The hefty 1,000-plus-pound screen is far from ordinary, either, and features a condenser lens and a diffuser film to smooth the transition between viewing angles. An improved version of this glasses-free 3D system with 200 viewpoints is in the pipeline as well. Unfortunately, according to Akihabara News, there's no indication this technology will make it way into consumer electronics as it was originally conceived for design and digital-signage applications.
