摘要:
The following invention relates to an improved lens apparatus for use in a head up display (HUD), particularly for providing HUD with a depth of field and more particularly with providing a secondary virtual image in a different colour so as to provide a warning message. The partially reflecting combiner has a first surface S 1 located closest to a display, and a second surface S 2 , located furthest from the display, wherein the effective radius of curvature of surface S 2 >S 1 so as to provide two non- coincident virtual images. The selection of antireflective coatings on the surfaces S 2 and S 1 allows the non-coincident virtual images to have different coloured virtual images.

以下发明涉及一种用于头顶显示器(HUD)中的改进的透镜装置,特别是用于为HUD提供景深,并且更具体地提供以不同颜色提供次虚拟图像以提供警告消息。 部分反射组合器具有最靠近显示器的第一表面S1和位于离显示器最远的第二表面S2,其中表面S2> S1的有效曲率半径以提供两个非重合虚拟图像。 在表面S2和S1上选择抗反射涂层允许非重合的虚拟图像具有不同的彩色虚像。
