Abstract

A three dimensional display apparatus comprising: a backlight to emit light from switchable apertures, the light being polarized; at least one light modulation panel with pixels that can be set to change the polarization of light; a polarizer that transmits light within a limited range of polarizations; where each light modulation panel can change the polarization such that the light passing through the polarizer can both increase and decrease irrespective of the polarization of light before passing the panel; and where the switching of the apertures are synchronized with the switching of the pixels on the at least one light modulation panel.
