Abstract

Interface de visualisation vidéo destinée à être utilisée avec des panneaux d'affichage électroluminescents C.C. et des circuits de commande de visualisation à courant constant. L'interface de visualisation vidéo reçoit des données vidéo en série à une cadence de défilement d'images de 60 Hz, les convertit en mots de huit bits et les stocke dans une mémoire vidéo à double tampon, d'après une topographie de mémoire ayant dix unités correspondant aux dix unités de visualisation logiques. L'interface de visualisation vidéo affiche des données vidéo stockées dans la topographie de mémoire, les convertit en mots de dix bits à sortie parallèle et envoie les mots de dix bits à des circuits de commande d'affichage pour commander simultanément plusieurs sections de l'écran de visualisation à une cadence de défilement de 240 Hz. L'interface de visualisation vidéo génère également des signaux de commande à courant constant et de pré-charge utilisés par les circuits de commande d'affichage pour générer des signaux à courant constant et de pré-charge, afin de commander l'écran de visualisation.
