Abstract

DISPOSITIF D'AFFICHAGE LUMINESCENT COMPRENANT UNE PLAQUE TRANSPARENTE, UNE COUCHE DE MATIERE LUMINESCENTE, OU PHOSPHORE, SUR LA SURFACE INTERIEURE DE LA PLAQUE ET UNE PELLICULE NON HOMOGENE, ABSORBANT LA LUMIERE, QUI ADHERE A LA COUCHE DE PHOSPHORE. LA PELLICULE PRESENTE UNE COMPOSITION QUI VARIE DE MANIERE CONTINUE A TRAVERS LA PELLICULE ET DEVIENT D'UN OXYDE METALLIQUE A L'INTERFACE PHOSPHORE-PELLICULE LE METAL CONSTITUTIF DE L'OXYDE DANS UNE ZONE ELOIGNEE DE CETTE INTERFACE DE TELLE SORTE QUE LA PELLICULE PRESENTE UN GRADIENT CONTINU D'INDICE DE REFRACTION ALLANT APPROXIMATIVEMENT DE L'INDICE DE REFRACTION DU PHOSPHORE JUSQU'A CELUI DU METAL, L'OXYDE METALLIQUE ETANT DE L'OXYDE DE TANTALE OU DE VANADIUM. L'INVENTION EST APPLICABLE NOTAMMENT A DES TUBES CATHODIQUES ET DES PANNEAUX LUMINESCENTS.
