A head up display assembly includes an optical system () and a transmissive display. A light source is configured to projected a light through the transmissive display. A diffuser () is located between the optical system and the transmissive display ().

Head up display assembly and method

The present invention relates to a head up display system, in particular for a motor vehicle, comprising: a picture generating unit having a picture projection optics, a tilted mirror and an intermediate image plane, wherein light from the picture projection optics is deflected by the mirror toward the backside of the intermediate image plane, and an optical lens and/or mirror arrangement for magnifying and/or conveying a picture generated on the intermediate image plane to an optical combiner, wherein a pair of prisms is inserted in the optical path between the tilted mirror and the intermediate image plane to eliminate or mitigate specific light beams emanating from the intermediate image plane and traveling toward the tilted mirror and/or specific light beams emanating from the intermediate image plane already being reflected from the tilted mirror and traveling back toward the intermediate image plane.
