Beschreibung
Zusammenfassung:	The present invention relates to an optical device for privacy or contrast enhancement of a viewing display. Also disclosed are a system including the optical device and methods of improving privacy or contrast of a viewing display, such as a plasma display panel, a liquid crystal display panel, an inorganic light emitting diode display panel, or an organic light emitting diode display panel. La présente invention porte sur un dispositif optique pour l'amélioration du caractère privé ou de contraste d'un dispositif d'affichage de visualisation. L'invention porte également sur un système comprenant le dispositif optique et sur des procédés d'amélioration du caractère privé ou du contraste d'un dispositif d'affichage de visualisation, tel qu'un panneau d'affichage à plasma, un panneau d'affichage à cristaux liquides, un panneau d'affichage à diodes électroluminescentes inorganiques ou un panneau d'affichage à diodes électroluminescentes organiques.
