Abstract:
A heads-up display system is configured for use in a vehicle. The system includes a standard vehicle window (i.e. no special coatings), an image projector, and a vehicle dashboard equipped with a faceted reflective surface. The image projector is configured to project an image onto the faceted reflective surface. The faceted reflective surface is configured to reflect the image from the image projector onto a window surface of the standard vehicle window. The window surface is oriented to reflect the image from the faceted reflective surface toward an occupant. The faceted reflective surface may be disposed within a plurality of troughs separated by a plurality of diffuse reflecting partitions. The plurality of troughs may be configured to shield the occupant from extraneous reflections. The faceted reflective surface may include a plurality of electrically controlled facets. The plurality of electrically controlled reflective facets may be an array of electrowetting cells.
