Heads-up display, motor vehicle and method of operating a heads-up display

摘要

A heads-up display comprises a monochrome display device for generating an image and an optical device for generating a virtual image from the image of the display device. The monochrome display device comprises a display and a backlight for illuminating the display from its backside. The backlight comprises a first light source emitting light of a first color, a second light source emitting light of a second color, a first light guide coupled to the first light source, and a second light guide coupled to the second light source. The first and second light guides are disposed in such close juxtaposition behind the display so that they illuminate together the entire backside of the display and illuminate a first region of the display associated with the first light guide with the first color and a second region of the display associated with the second light guide with the second color.
