Abstract
Invention concernant un dispositif électrique d'affichage. Dispositif de visualisation à cristal liquide, avec circuit de commande électronique qui excite des électrodes disposées sur les faces opposées du cristal. Des électrodes concentriques sont divisées en segments; des groupes de barres électrodes formant des secteurs de l'affichage coopèrent, pour chaque secteur, avec un segment intérieur et avec un segment extérieur et les barres électrodes d'un secteur sont reliées dans l'ordre inverse aux barres électrodes du secteur suivant Le circuit électronique choisit un ou des segments dans un secteur requis et modifie en conséquence l'ordre de sélection des barres. Application à l'affichage simultané de trois variables.
