Abstract

L'invention se rapporte aux dispositifs d'affichage. L'invention concerne une lampe d'affichage ayant 4 filaments verticaux B', C', E', F' et 3 filaments horizontaux A', G', D' qui sont commutés sélectivement pour la présentation d'un chiffre, d'up repère ou d'un symbole. Des plaques d'électrodes sont soudées aux fils et moulées préalablement afin que les extrémités des filaments horizontaux et les extrémités des filaments verticaux se superposent exactement mais se trouvent à des niveaux différents. Application à la réalisation de dispositifs d'affichage pour aéronefs.
