Parallax barrier

From Wikipedia, the free encyclopedia

A parallax barrier is a device to allow a liquid crystal display to show a three dimensional image without the need for the viewer to wear glasses. Placed behind the normal LCD, it consists of a layer of material with a series of precision slots, allowing each eye to see a different set of pixels, so creating a sense of depth through parallax.[1][2] A disadvantage of the technology is that the viewer must be positioned in a well defined spot to experience the 3D effect.[3] In addition to films and computer games, the technique has found uses in areas such as molecular modelling and airport security.[4]
