Abstract

Un dispositif d’affichage comprend des roues colorées rotatives (12, 14), afin de générer un faisceau coloré périodique, et un imageur (16) qui module le faisceau coloré en fonction d’un signal vidéo reçu (V RGB). Le faisceau coloré (8) prend successivement à chaque période une pluralité de couleurs de base (a, β, Ϝ) en synchronisme avec les images générées par l’imageur pour chaque couleur de base (a, β, Ϝ). Par le réglage de la position relative (ϕ) des roues colorées (12, 14), on peut modifier la teinte des couleurs de base (a, β, Ϝ) afin de les adapter au mieux au signal vidéo reçu (V RGB).
