Title (EN) DISPLAY DEVICE FOR VEHICLES
(FR) DISPOSITIF D'AFFICHAGE POUR VÉHICULES
(JA) 車両用表示装置
Abstract:
(EN) This display device for vehicles is provided with: a display part (20); a light guide plate (30) which is arranged closer to the viewing side than the display part, while having light transmitting properties; and a light source part (50) which has light source light enter into the light guide plate through a peripheral part (32) of the light guide plate. The light guide plate has a reflection part (36) having a plurality of reflective elements (37) which reflect the light source light from the light source part toward the viewing side. Each reflective element has a reflective curved surface (37a) that has a curved shape and faces the peripheral part on which the light source light is incident.
(FR) L'invention concerne un dispositif d'affichage pour véhicules comprenant : une partie d'affichage (20) ; une plaque de guidage de lumière (30) qui est disposée plus près du côté de visualisation que de la partie d'affichage, tout en présentant des propriétés de transmission de lumière ; et une partie source de lumière (50) dont la lumière de source de lumière pénètre dans la plaque de guidage de lumière à travers une partie périphérique (32) de la plaque de guidage de lumière. La plaque de guidage de lumière possède une partie réfléchissante (36) comportant une pluralité d'éléments réfléchissants (37) qui réfléchissent la lumière de la source de lumière en provenance de la partie source de lumière vers le côté de visualisation. Chaque élément réfléchissant comporte une surface incurvée réfléchissante (37a) qui a une forme incurvée et fait face à la partie périphérique sur laquelle la lumière de la source de lumière est incidente.
(JA) 車両用表示装置は、表示部(20)と、表示部よりも視認側に配置され、透光性を有する導光板(30)と、導光板の外縁部(32)を介して内側へと光源光を入射させる光源部(50)と、を備える。導光板は、光源部からの光源光を視認側に反射する複数の反射素子(37)を有する反射部(36)を有する。反射素子は、光源光が入射する外縁部を向き、曲面状に形成された反射湾曲面(37a)を有する。
