Abstract

Ecran à électroluminescence excitée par un courant alternatif. Les couches de poudre électroluminescente consistent en couche d'épaisseur monoparticulaire qui sont enrobées dans une résine thermoplastique dont la constante diélectrique est plus élevée que celle des particules de la poudre enrobée. Application à l'affichage numérique et aux écrans de télévision en noir et blanc et en couleur.
