Abstract

L'invention concerne un dispositif d'affichage (2) destiné à délivrer optiquement, vers l'extérieur, un état de fonctionnement interne d'un appareil électrique, le dispositif d'affichage (2) étant conçu pour être disposé sur l'appareil électrique de manière à être visible de l'extérieur, et présentant au moins un point lumineux discret (4), apte à être commandé séparément, pour délivrer en sortie l'état de fonctionnement de l'appareil électrique. Il est proposé que le dispositif d'affichage (2), en tant que représentation d'un état de fonctionnement particulier de l'appareil électrique et sur la base de l'état de fonctionnement, - active et/ou désactive une combinaison de multiples points lumineux (4) du dispositif d'affichage (2) et/ou - commute au moins un point lumineux (4) du dispositif d'affichage (2) en va-et-vient entre un état activé et un état désactivé afin de délivrer en sortie l'état de fonctionnement de l'appareil électrique.
