Abstract

L'invention concerne les dispositifs d'affichage à sept segments. Le dispositif d'affichage de l'invention comporte un étage d'affichage supérieur, comportant les segments PUA, PUB, etc., et un étage d'affichage inférieur comportant les segments PLA, PLB, etc. Les deux étages d'affichage sont placés cote à côte et séparés par un écran M, N qui empêche toute interaction parasite. Un tel affichage permet d'afficher simultanément les deux opérandes d'une opération. Application aux calculatrices de poche.
