Abstract

An autostereoscopic display includes an image forming device and a substrate having alternating strips, where strips having a first optical property are separated by strips having a different optical property. This substrate may be composed of alternating strips of polarization film separated by clear, nonpolarizing strips. Alternately, this substrate may be composed of first alternating strips that retard a component of linearly polarized light by one-half wavelength, separated by second alternating strips that retard a component of linearly polarized light by one wavelength. A removable, separate polarizing substrate may be removably placed in front of the substrate containing the alternating strips. When the removable polarizing substrate is placed in front of the strips in a certain orientation, autostereoscopic imaging is viewed by the observer, and when this polarizing substrate is removed, 2D imaging is viewed.
