Abstract

Dispositif d'affichage de véhicule Un dispositif d'affichage de véhicule comprend : un affichage réfléchissant (30, 400) configuré pour fournir l’affichage vers un extérieur du véhicule ; et un élément d'émission de lumière agencé pour faire face à une partie d'affichage (31, 150) de l’affichage réfléchissant (30, 400). L’élément d'émission de lumière est configuré pour permettre à la lumière destinée à être incidente à partir de la partie d'affichage (31, 150) et à la lumière destinée à être incidente à partir d’un côté opposé au côté de la partie d'affichage (31, 150) de passer à travers l’élément d'émission de lumière, et est configuré pour émettre la lumière vers la partie d'affichage (31, 150), qui est différente de la lumière destinée à être incidente à partir du côté de la partie d'affichage (31, 150) et de la lumière destinée à être incidente à partir du côté opposé au côté de la partie d'affichage (31, 150).
