摘要

The head up display has a display screen (11) which passes light information using a reflecting mirror (50) to a windscreen (20) at head height. The reflecting mirror can be set to two positions. In the first position light from the sun is reflected from the mirror surface (51) to illuminate the display mechanism. In the second position, rear optical illumination is used.
