Abstract

Pour reproduire un phénomène ou un nombre réduit de phénomènes à l'aide d'un oscilloscope muni d'un écran de reproduction à cristal liquide, l'invention fournit un circuit de commande matriciel simple par l'emploi duquel la commande par multiplexage de temps de nombreuses lignes est possible tout en donnant lieu à un contraste convenable si, par colonne, il suffit d'amener en situation << TOUT >> un seul ou tout au plus quelques points d'image, cette commande avec ce constraste étant possible sans nécessiter des prévisios coûteuses, par exemple une stabilisation de tension et une stabilisation de température. Application aux oscilloscopes.
