Glasses Free 3D

Forget about silly-looking, uncomfortable 3-D glasses. Philips's new 3-D displays create the illusion of depth by overlaying an LCD screen with tiny lenses that direct slightly different images to the viewer's eyes. The illusion persists within a 120º viewing area. The displays work only with specially created content, so Philips is currently marketing them for use in promotional displays--at malls, casinos, and movie theaters, for instance. But it hopes to have 3-D TVs in homes within a few years.
