Title (EN) HEADUP DISPLAY DEVICE
(FR) DISPOSITIF D'AFFICHAGE TÊTE HAUTE
(JA) ヘッドアップディスプレイ装置
Abstract:
(EN) Provided is a headup display device that suppresses luminance variance of diffusion light with respect to an obliquely disposed screen. A screen (40) is tilted with respect to an orthogonal plane (43) that is orthogonal to an optical axis (41a) of projection light (41). In the cases where the screen (40) and the optical axis (41a) of the projection light (41) are orthogonal to each other, a center line (45) of a distribution angle (β) of diffusion light (42) is set such that the center line tilts in a direction (C) with respect to an output surface (46) of the screen (40), said direction (C) being identical to a tilt direction (C) of the screen (40).
(FR) L'invention concerne un dispositif d'affichage tête haute qui supprime la variance de luminance de la lumière de diffusion par rapport à un écran disposé obliquement. Un écran (40) est incliné par rapport à un plan orthogonal (43) qui est orthogonal à un axe optique (41a) de la lumière de projection (41). Dans les cas où l'écran (40) et l'axe optique (41a) de la lumière de projection (41) sont orthogonaux l'un par rapport à l'autre, une ligne centrale (45) d'un angle de distribution (β) de lumière de diffusion (42) est réglé de telle sorte que la ligne centrale s'incline dans une direction (C) par rapport à une surface de sortie (46) de l'écran (40), ladite direction (C) étant identique à une direction d'inclinaison (C) de l'écran (40).
(JA) 斜めに配置されたスクリーンについて、拡散光の輝度の差異を抑制するヘッドアップディスプレイ装置を提供すること。 スクリーン(40)は、投射光(41)の光軸(41a)に直交する直交面(43)に対して傾いている。投射光(41)の光軸(41a)とスクリーン(40)とが直交する場合の拡散光(42)の配光角(β)の中心線(45)は、スクリーン(40)の出射面(46)に対して、スクリーン(40)の傾き方向(C)と同じ方向(C)に傾くように設定されている。
