Abstract

L’invention concerne un élément d’affichage permettant de commuter l’affichage et de l’élargir afin de faciliter la visualisation. L’invention concerne également un élément d’interrupteur à bouton-poussoir utilisant ledit élément. L’élément d’affichage (1, 100) présente une zone d’affichage superposée (30), au moins une première zone d’affichage (10) et une deuxième zone d’affichage (20) étant partiellement superposées sur une surface d’affichage. Ladite première zone d’affichage (10), sans la zone d’affichage superposée (30), présente une première couche filtrante (51). La deuxième zone d’affichage (20), sans la zone d’affichage superposée (30), présente une deuxième couche filtrante (52). La première couche filtrante (51) émet plus facilement de la lumière dans une première bande de longueur d’onde prescrite mais émet de la lumière moins facilement dans une deuxième bande de longueur d’ondes prescrite par rapport à la deuxième couche filtrante (52). La deuxième couche filtrante (52) émet plus facilement de la lumière dans la deuxième bande de longueur d’ondes prescrite mais émet de la lumière moins facilement dans la première bande de longueur d’ondes prescrite par rapport à la première couche filtrante (51). La zone d’affichage superposée (30) émet de la lumière à la fois dans la première bande de longueur d’ondes prescrite et dans la deuxième bande de longueur d’ondes prescrite.
