Title
(EN) VEHICLE DISPLAY SYSTEM WITH REFLECTION CONTROL
(FR) SYSTÈME D'AFFICHAGE POUR VÉHICULE AVEC COMMANDE DE RÉFLEXION
Abstract
(EN)
A display system for a vehicle comprises a display device disposed inside a passenger compartment of the vehicle. The passenger compartment is configured to receive light from a first polarization filter disposed on a light-transmissive panel of the vehicle. The first polarization filter is oriented in a first orientation and the display device is configured to display video data from a display screen. The display device comprises an electro-optic element comprising a plurality of substrates and a second polarization filter disposed on at least one of the plurality of substrates. The second polarization filter is oriented in a second orientation parallel to the first orientation.

L'invention concerne un système d'affichage pour un véhicule comprenant un dispositif d'affichage disposé à l'intérieur d'un habitacle du véhicule. L'habitacle est configuré pour recevoir de la lumière en provenance d'un premier filtre de polarisation disposé sur un panneau transmettant la lumière du véhicule. Le premier filtre de polarisation est orienté dans une première orientation et le dispositif d'affichage est configuré pour afficher des données vidéo provenant d'un écran d'affichage. Le dispositif d'affichage comprend un élément électro-optique qui comporte une pluralité de substrats et un deuxième filtre de polarisation disposé sur au moins l'un de la pluralité de substrats. Le deuxième filtre de polarisation est orienté dans une deuxième orientation parallèle à la première orientation.
