Heres a pretty good explanation of phillips 3D.

Here's how they work. None of the image processing takes place beforehand; it happens inside the display, which accepts a DVI input carrying a 2D image plus a "depth map" — in this case, an 8-bit (256-level) representation of depth within that image. (Philips calls this the "2D-plus-depth" format.) The display uses that depth map to create different "views" of the 2D image corresponding to the parallax that would be perceived by human eyes. In all, nine different images are displayed simultaneously. The screen is covered by a series of very thin lenses that diffract the light so that the eyes of an observer will see two different images that create the perception of 3D.
