Abstract

La présente invention se rapporte à un appareil d'affichage utilisant un rétroviseur. Cet appareil est pourvu d'un panneau d'affichage à cristaux liquides (ACL) (2) et d'un panneau foncé (3), ainsi que d'un miroir réfléchissant (4) qui recouvre lesdits panneaux (2) et (3). En mode classique, l'appareil d'affichage permet au conducteur de voir la zone se trouvant derrière le véhicule grâce au miroir réfléchissant (4). En mode affichage d'images arrières faisant appel à une caméra CCD (5), le panneau ACL (2) affiche une image arrière photographiée par ladite caméra (5). En mode affichage de navigation faisant appel à un système de navigation (18), le panneau ACL (2) affiche une image cartographique. En mode télévision, une unité de traitement de signaux de télévision (15) délivre un signal vidéo au panneau ACL (2) et délivre un signal audio à un haut-parleur (17). Le fonctionnement de cet appareil est commandé par une unité de commande (12).
