Title (EN) HEAD-UP DISPLAY
(FR) AFFICHEUR TÊTE HAUTE
(JA) ヘッドアップディスプレイ
Abstract:
(EN) This head-up display has a display device that emits a display light for projecting a background image and a display element, and a mirror device that causes the display light emitted by the display device to be reflected on a front glass, wherein the display light for projecting the background image having a lower brightness than the brightness of the display element is reflected by the mirror device, and/or a background image display light for projecting, on the front glass, the background image included in the display light is reflected by the mirror device in a direction in which the background image cannot be seen by the driver.
(FR) L'invention se rapporte à un afficheur tête haute qui comporte un dispositif d'affichage émettant une lumière d'affichage conçue pour projeter une image d'arrière-plan et un élément d'affichage, ainsi qu'un dispositif miroir provoquant la réflexion, sur une vitre avant, de la lumière d'affichage émise par le dispositif d'affichage. La lumière d'affichage prévue pour projeter l'image d'arrière-plan présentant une luminosité inférieure à la luminosité de l'élément d'affichage est réfléchie par ce dispositif miroir, et/ou une lumière d'affichage d'image d'arrière-plan destinée à projeter, sur la vitre avant, l'image d'arrière-plan incluse dans la lumière d'affichage est réfléchie par ledit dispositif miroir dans une direction où l'image d'arrière-plan ne peut pas être vue par le conducteur.
(JA) 背景画像と、表示要素とを投影させるための表示光を出射する表示装置と、表示装置により出射された表示光をフロントガラスに反射させるミラー装置と、を有するヘッドアップディスプレイであって、ミラー装置に、輝度を表示要素の輝度よりも低くさせた背景画像を投影させるための表示光を反射させる、および/または、表示光に含まれる背景画像をフロントガラスに投影させるための背景画像表示光を背景画像が運転者に視認されない方向へ反射させる。
