Abstract

Cette invention concerne des écrans comprenant une première lentille ou couche d'élément optique holographique et une seconde couche de masque. La première couche collimate sensiblement les rayons lumineux d'une image de sorte qu'ils heurtent la couche de masque. La couche de masque produit un réseau ou une matrice d'éléments de projection. Chacun des éléments de projection reçoit et focalise les rayons lumineux sensiblement collimatés en points focaux correspondants. La couche de masque comprend un masque qui bloque la transmission de lumière sauf aux emplacements des orifices. Ces orifices permettent à la lumière focalisée par les points focaux de traverser sensiblement le masque afin qu'une image soit formée. Ces écrans peuvent être utilisés dans des appareils d'affichage.
