Abstract
(EN) Provided is a headup display apparatus for vehicles, said headup display apparatus being capable of suppressing deterioration of luminance of virtual images, while avoiding a cost increase. This headup display apparatus is provided with: a light emitting unit (70) having at least a light emitting body (72) that emits output light (L2); a liquid crystal display (20) which emits display light (L1); a concave mirror (41) which reflects the display light (L1); and a housing (80) which houses the light emitting unit (70), the liquid crystal display (20), and the concave mirror (41). The output light (L2) that has been emitted from the light emitting body (72), and the display light (L1) that has been reflected by the concave mirror (41) are radiated to a windshield (13) through a translucent cover (85), and a virtual image (V) obtained by means of the radiation is visually recognized by a driver (14). The light emitting unit (70) is disposed inside of the housing (80) such that the light emitting unit faces the windshield (13) with the translucent cover (85) therebetween.
(FR) L'invention concerne un appareil d'affichage tête haute pour des véhicules, ledit appareil d'affichage tête haute étant capable de supprimer la détérioration de la luminance d'images virtuelles tout en évitant une augmentation du coût. L'appareil d'affichage tête haute selon l'invention comprend : une unité d'émission de lumière (70) comportant au moins un corps d'émission de lumière (72) qui émet une lumière de sortie (L2) ; un écran à cristaux liquides (20) qui émet une lumière d'affichage (L1) ; un miroir concave (41) qui réfléchit la lumière d'affichage (L1) ; et un boîtier (80) dans lequel sont logés l'unité d'émission de lumière (70), l'écran à cristaux liquides (20) et le miroir concave (41). La lumière de sortie (L2) émise à partir du corps d'émission de lumière (72) et la lumière d'affichage (L1) réfléchie par le miroir concave (41) sont projetées en direction d'un pare-brise (13) à travers un cache translucide (85), et une image virtuelle (V) obtenue par le biais de la projection est reconnue visuellement par un conducteur (14). L'unité d'émission de lumière (70) est disposée à l'intérieur du boîtier (80) de façon à faire face au pare-brise (13), le cache translucide (85) étant interposé entre eux.
