Abstract
Stereoscopic effects can be created by binocular parallax. Known stereoscopic display systems show pseudoscopic effects in outer areas of the image viewing position and the viewing position is fixed. To avoid such pseudoscopic effects and/or to change the viewing position stereoscopic displays using parallax barriers with variable pitch length, moving barriers parallel to the display plane, and a polarizing device forming polarized light together with polarizing prisms are provided.
