Abstract
(EN)
Provided is an information display device (100) that displays video information of a virtual image on the windshield (5) of a vehicle, wherein: the information display device (100) comprises a housing (6); a part of the housing includes an opening (41) and a transparent cover provided over the opening (4); the housing stores a video light generation means (3) that generates video light for displaying video information and an optical system (1) that allows a driver of the vehicle to recognize the video information as a virtual image in front of the windshield (5), the video information displayed using video light from the video light generation means (3); given that S polarized light is defined as a first polarized wave relative to the windshield (5) and polarized light with the polarization direction perpendicular to the first polarized wave is defined as a second polarized wave, the video light generation means (3) is configured to generate the video light using the first polarized wave; and the information display device (100) is provided with transmittance and reflectance control means (1 or 2) for blocking part of the second polarized wave and first polarized wave of external light that enters the housing (6) through the opening (41). The information display device (100) has significantly improved sunlight resistance.
(FR)
La présente invention concerne un dispositif d’affichage d’informations (100) qui affiche des informations vidéo d’une image virtuelle sur le pare-brise (5) d’un véhicule, dans lequel : le dispositif d’affichage d’informations (100) comprend un boîtier (6) ; une partie du boîtier comprend une ouverture (41) et un couvercle transparent disposé au-dessus de l’ouverture (4) ; le boîtier stocke un moyen de génération de lumière vidéo (3) qui génère une lumière vidéo pour afficher des informations vidéo et un système optique (1) qui permet à un conducteur du véhicule de reconnaître les informations vidéo sous la forme d’une image virtuelle devant le pare-brise (5), les informations vidéo affichées au moyen de la lumière vidéo provenant du moyen de génération de lumière vidéo (3) ; étant donné que la lumière polarisée S est définie comme une première onde polarisée par rapport au pare-brise (5) et une lumière polarisée ayant la direction de polarisation perpendiculaire à la première onde polarisée est définie comme une deuxième onde polarisée, le moyen de génération de lumière vidéo (3) est configuré pour générer la lumière vidéo au moyen de la première onde polarisée ; et le dispositif d’affichage d’informations (100) est pourvu de moyens de commande de transmittance et de réflectance (1 ou 2) pour bloquer une partie de la deuxième onde polarisée et une première onde polarisée de lumière externe qui pénètre dans le boîtier (6) à travers l’ouverture (41). Le dispositif d’affichage d’informations (100) présente une résistance à la lumière du soleil significativement améliorée.
