  • Patent number: 7762703
    Abstract: 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.

  • Publication number: 20080192312
    Abstract: The invention relates to a holographic information display for a motor vehicle for projecting a virtual display element. A data processing device provides a hologram for the virtual display element to be projected. A control device in each case emits an individual control signal for a plurality of segments of the hologram. A plurality of optical phase delay cells which can be individually adjusted by the control device and are arranged on a face illuminated by the light beam, delay the fraction of the light beam incident thereon in each case in the phase in response to the respective individual control signal.

  • Publication number: 20080192045
    Abstract: In a holographic heads-up display, a first set of data and a second set of data are provided. A three-dimensional image or scenery displaying the first set of data in a first layer and the second set of data in a second layer are created. The first layer is separated from the second layer by a specified distance. A hologram is determined, which corresponds to a recording of the scenery via a reference beam. A plurality of controllable phase delay elements are set according to the determined hologram. The hologram is reconstructed by illuminating the plurality of phase delay elements using a coherent light source. The light of the reconstructed hologram is directed into the visual field of a driver via a wind screen of a vehicle.
