Abstract

Cette invention se rapporte à un polariseur réflectif multicouche (12), qui est placé entre une cavité optique (24) et un module d'afficheur à cristaux liquides (16), afin de former un afficheur optique. Ce polariseur réflectif réfléchit une partie de la lumière dans la cavité optique (24), où elle est randomisée et d'où elle peut finalement sortir avec la polarisation correcte pour être transmise hors de l'afficheur.
