Abstract

L'invention concerne un agencement pour minimiser la lumière réfléchie par un affichage. Selon l'invention, l'affichage comprend un moyen 10 pour changer la polarisation de la lumière, ayant des premier et second côtés opposés, un premier moyen 14 d'analyse de la lumière adjacent au premier côté et un moyen 16 de diffusion de la lumière entre le premier côté et le moyen d'analyse. L'invention s'applique notamment aux affichages. (CF DESSIN DANS BOPI)
