  • Patent number: 10598930
    Abstract: A multi-eyebox head-up display device and a multilayer combiner are disclosed. The device comprises a projector generates a projected image to a reflector. The reflector generates a reflected image to a multilayer combiner. The multilayer combiner includes at least two superimposed imaging plates, and the semi-reflective surfaces of the superimposed imaging plates are tilted to each other. While the reflected image is projected to the semi-reflective surface of the topmost superimposed imaging plate, the semi-reflective surface of the topmost superimposed imaging plate generates a virtual image. Simultaneously, the reflected image penetrates through the topmost superimposed imaging plate and reaches the lower superimposed imaging plate, and the semi-reflective surface of the lower superimposed imaging plate reflects the light to generate another virtual image. The present invention enables the driver to view the vehicular information at different viewing angles.
