Abstract

Panneau d'affichage plasma à masque perforé à décharge de surface comprenant une plaque avant, une plaque arrière, un masque perforé conducteur comportant une grille perforée situé entre ces deux plaques et les maintenant en place, une électrode de balayage et une électrode de support situées sur la plaque avant ainsi qu'une électrode d'adressage située sur la plaque arrière formant avec la grille perforée du masque perforé conducteur une unité de décharge. En mode opérationnel de décharge de surface, une poudre fluorescente est appliquée non seulement sur les parois internes de la grille perforée du masque perforé, mais aussi à sur l'emplacement de l'unité de décharge sur la plaque arrière, la surface d'application de la poudre fluorescente étant ainsi plus large que celle de l'unité de décharge correspondant au masque perforé, augmentant de ce fait la luminescence et l'efficience lumineuse.
