Researchers from MIT will demonstrate a new method for creating glasses-free 3D displays when they present a paper at Siggraph later this summer. The new proposal uses either three separate layers of LCDs with a single backlight, or two LCDs with lenses between them to refract light left and right.
The three layer solution has a viewing angle of around 20 degrees, whilst the two layer solution improves that to 50 degrees. Watch the video for a demonstration!
