Definition: lenticular 3D

A type of glasses-free 3D (autostereoscopic) technology that separates the image into left and right frames. Lenticular 3D uses a convex lens to direct the eyes appropriately. Left and right frames appear as columns of pixels or blocks of pixels for multi-view images.

Having evolved from lenticular printing methods that create the illusion of depth on printed matter, a layer of lenticular lenses in front of an LCD screen directs the stereo frames to the appropriate eyes. Used on large screens in stores and shopping malls, this technique creates a more eye-popping display than regular 2D signage. See parallax 3D, 3D visualization, 3D rendering and lenticular printing.

The lens directs the left image to the left eye and the right image to the right eye.
