MIT postdoc researcher Gordon Wetzstein and Ph.D. student Matt Hirsch explain a new glasses-free 3D flat-panel technology they are working on at the MIT Media Lab. Conventional stereoscopic displays show two views (left and right eye) in a narrow viewing area, and all viewers see the same perspective. The new display shows many perspectives across a wider area, providing each viewer with a different perspective, much like a hologram. The new display combines several LCD layers, directional backlighting, and sophisticated processing to achieve its remarkable result. This isn't going to be a commercial product any time soon, but it does point the way toward a more realistic 3D display without needing those annoying glasses.
