Abstract

L'invention concerne un ensemble écran d'un système vidéo à rétroprojection, qui comporte un écran à nervures croisées et à gain vertical et horizontal variable, un écran à vibrations et à nervures croisées, ayant un champ variable vertical et horizontal, un écran à petites lentilles chevauchantes, un ensemble écran permettant de réduire la tavelure, de supprimer la réflexion et de réduire la perte lumineuse, et permettant également de fournir une protection de la surface de l'écran tout en offrant un meilleur contraste. L'invention concerne également une technique de montage de l'ensemble écran dans le système vidéo à rétroprojection.
