Abstract

L'invention concerne les dispositifs d'affichage Un dispositif d'affichage comprend notamment un diviseur de fréquence DV1 et un diviseur de fréquence DV2. Le diviseur DV1 divise dans le même rapport le signal d'horloge de point et le signal d'horloge de caractère, ce qui multiplie de façon correspondante la largeur de chaque caractère affiché, et le diviseur DV2 divise la fréquence des ordres d'adresse de rangée, ce qui multiplie de façon correspondante la hauteur de chaque caractère affiché. On peut ainsi faire varier la taille des caractères affichés, sans modifier la vitesse de balayage du tube cathodique. Application aux dispositifs d'affichage à tube cathodique.
