Philips’ WOWvx displays–which allow viewers to perceive high-quality 3-D images without the need for special glasses–are now beginning to appear in shopping malls, movie-theater lobbies, and theme parks worldwide.

The technology uses image-processing software, plus display hardware that includes sheets of tiny lenses atop LCD screens. The lenses project slightly different images to viewers’ left and right eyes, which the brain translates into a perception of depth.
