    • A head-up display apparatus includes a display unit outputting display light, a mirror for reflecting the display light toward an eye point, a mirror holder to be turned up/down for receiving and holding the mirror, a holder top cover extending toward the eye point when the mirror holder is turned up, and a holder rear cover so as to be placed at an opposite side of the eye point when the mirror holder is turned up. The holder rear cover has a surface shape to become in the same outline as that of the instrument panel when the holder rear cover covers totally an opening provided at the instrument panel in case that the mirror holder is turned down. The holder rear cover is continued to the holder top cover with an acute angle.
    • 平视显示装置包括:输出显示灯的显示单元,向眼睛反射显示光的反射镜;向上/向下翻转以接收和保持反射镜的反射镜保持器;朝向眼睛延伸的保持器顶盖 当镜子保持器翻转时,保持器后盖被放置在眼点的相反侧。 保持器后盖具有与仪表板相同的轮廓,当保持器后盖全部覆盖设置在仪表板上的开口时,在反射镜保持器向下转动的情况下。 保持器后盖以锐角继续到保持器顶盖。

    • An illumination device for an indicating needle includes a plurality of light sources, an indicating needle, a guiding member, and a luminance control unit. The indicating needle includes a needle body and a needle base. The base has an entrance surface and a reflection surface. A luminance control unit controls luminance of the light sources in response to turning of the indicating needle such that the luminance is lowest when a light emitted perpendicularly from a center of an emitting surface of the light source is reflected off a reflection surface's region which a longitudinal central line of the needle body intersects with, and that the luminance gradually increases as the light emitted by the light source from the center of the emitting surface thereof is reflected off a region that is more distant from the region which the longitudinal central line of the needle body intersects with.
    • 用于指示针的照明装置包括多个光源,指示针,引导构件和亮度控制单元。 指针包括针体和针座。 基座具有入射面和反射面。 亮度控制单元响应于指示针的转动来控制光源的亮度,使得当从光源的发射表面的中心垂直发出的光从反射表面的区域反射时,亮度最低,纵向 针体的中心线与光源的从其发射面的中心发出的光相反,并且随着光源从其发射表面的中心发射的光被从远离其发射表面的中心的区域反射的区域反射,亮度逐渐增加。 针体相交。

    • When a polarization axis of a first polarizing plate is parallel to that of a second polarizing plate, a light emitted from a backlight is transmitted, on the other hand, when a polarization axis of the first polarizing plate is orthogonal with that of the second polarizing plate, a light emitted from the backlight is mostly blocked off. A character and scale are constructed by a ½λ phase difference plate, so that the emitted light from the backlight, which enters to the character and scale, has a deflection direction reverse to that of the first polarizing plate. When the light emitted from the backlight is blocked, differently from a conventional artificial (pseudo) black color, a color extremely close to black color is seen. The contrast ratio and visibility are improved.
    • 当第一偏振片的偏振轴平行于第二偏振片的偏振轴时,从背光发出的光透射,另一方面,当第一偏振片的偏振轴与第二偏振片的偏振轴正交时, 板,从背光发出的光大多被阻挡。 由Λ相位差板构成字符和刻度,使得来自背光源的发射的光进入字符和刻度,其偏转方向与第一偏振片的偏转方向相反。 当从背光发出的光被阻挡时,与常规的人造(伪)黑色不同,看到非常接近黑色的颜色。 对比度和可视性得到改善。
