Title (EN) DISPLAY DEVICE FOR VEHICLE
(FR) DISPOSITIF D'AFFICHAGE POUR VÉHICULE
(JA) 車両用表示装置
Abstract:
(EN) Provided is a display device for a vehicle that can, in a configuration in which the cost of parts is curbed, quickly raise the temperature of a laser light source (LD) in a low temperature environment, and quickly perform stable image output. The LDs (11, 12, 13) emit laser light (RGB) and an MEMS mirror (30) scans the laser light (RGB) and generates a display image (M). A convex mirror (70) reflects display light (L) indicating the display image (M) in an external direction via a translucent light-transmitting unit (90). An LD driving means (101) emits laser light (RGB) to the LDs (11, 12, 13) when the temperature is low, and causes the LDs (11, 12, 13) to perform self-heating driving for raising the temperature of themselves.
(FR) La présente invention concerne un dispositif d'affichage pour véhicule susceptible, dans une configuration dans laquelle le coût des pièces est réduit, d'augmenter rapidement la température d'une source de lumière laser (LD) dans un environnement à basse température et d'effectuer rapidement une sortie d'image stable. Les LD (11, 12, 13) émettent une lumière laser (RVB). Puis un miroir MEMS (30) balaie la lumière laser (RVB) et produit une image d'affichage (M). Un miroir convexe (70) réfléchit la lumière d'affichage (L) indiquant l'image d'affichage (M) dans une direction externe par l'intermédiaire d'une unité translucide de transmission de lumière (90). Un moyen de commande de LD (101) émet une lumière laser (RVB) vers les LD (11, 12, 13) quand la température est basse et amène les LD (11, 12, 13) à exécuter une commande d'autochauffage afin d'augmenter leur propre température.
(JA)  部材費を抑えた構成において、低温環境下におけるレーザー光源(LD)を速やかに昇温することができ、安定した画像出力を速やかにおこなうことができる車両用表示装置を提供する。 LD11,12,13はレーザー光RGBを射出し、MEMSミラー30はこのレーザー光RGBを走査して表示画像Mを生成し、凹面ミラー70は表示画像Mを表す表示光Lを透光性の透光部90を介して外部方向へ反射し、LD駆動手段101は、低温時にLD11,12,13にレーザー光RGBを射出させ、LD11,12,13自身を昇温する自己発熱駆動を行わせる。
