Abstract

Dispositif dans lequel des ponts contacteurs relient les connexions non utilisées et la connexion à l'électrode arrière ou électrode constituant le << commun >> de sélection se trouvant sur la petite plaquette de verre afin d'éviter que les conductivités latérales résiduelles aient pour effet que les caractères non utilisés ne soient partiellement pas éliminés de la sélection et donc soient visibles. Une barrette obturatrice 7 de la cellule et à conductivité contrôlée intègre les ponts contacteurs dans le dispositif d'affichage lui-même Application à la fabrication en série de dispositifs d'affichage dans lesquels certains signes ou caractères ne sont pas utilisés dans certaines applications.
