  • Patent number: 10317677
    Abstract: A display system comprises an optical waveguide, an actuator and a light engine. The light engine generates multiple input beams which form a virtual image. An incoupling grating of the optical waveguide couples each beam into an intermediate grating of the waveguide, in which that beam is guided onto multiple splitting regions. The intermediate grating splits that beam at the splitting regions to provide multiple substantially parallel versions of that beam. Those multiple versions are coupled into an exit grating of the waveguide, in which the multiple versions are guided onto multiple exit regions. The exit grating diffracts the multiple versions of that beam outwardly. The multiple input beams thus cause multiple exit beams to exit the waveguide which form a version of the virtual image. The actuator is coupled to the waveguide and is arranged to generate acoustic waves, which are incident on, and propagate through, the optical waveguide.

  • Patent number: 10310262
    Abstract: The problem addressed by the present invention is to provide a head-up display device suitable for a curved windshield in a head-up display device provided with a combiner and a cover wherein the cover moves in the longitudinal direction of the vehicle. A front part of a guide rail extending in the longitudinal direction of the vehicle is curved downward. A cover, which moves along this guide rail, is moved by a drive link and a driven link. Because the curved guide rail is used, the dimension of a head-up display device in the longitudinal direction of the vehicle can be reduced, a large inclined surface can be provided on the upper front part of a housing, and the head-up display device can be placed close to a curved windshield.
