Definitions

  • the present invention relates to a display device, in particular a motor vehicle display device, which generates virtual images by means of a projector and an at least partially reflecting surface.
  • Such a display device is described, for example, in the press release “For the Trade and Business Press” Frankfurt / Main of September 11, 2001, Information SV 200 109.001 d, published by Siemens VDO Automotive AG.
  • a display device of the type mentioned at the outset is proposed, in which a projector is arranged under an inclined partially reflecting, transparent surface (also called a combiner for short).
  • the projector has a light source, a translucent display and one
  • Optical lens forming the beam path and creates a fixed virtual image in the vehicle front area in the eye of the beholder.
  • a reflector is connected between the light source and a display, which can be designed as a thin film transistor (TFT) display for color image generation.
  • TFT thin film transistor
  • the light rays are then directed over several mirrors which serve to compensate for the curvature of the windshield.
  • One of these mirrors can be rotated, so that the overlay in the windscreen can be adapted to the driver's seat position.
  • the driver does not see the image on the glass surface, but hovers freely about two meters above the bonnet.
  • the light source is very bright and is speed sensor controlled. The size and scope of the information displayed can be freely selected.
  • a head-up display which provides a driver with more information with undisturbed attention.
  • This system is borrowed from aircraft technology and is designed to increase traffic safety.
  • Information is transmitted to a dynamic display device, such as a video screen or a liquid crystal screen, which is located in the dashboard.
  • the screen image is then projected onto the windshield at the driver's eye level.
  • the windshield can be covered with a semi-reflective layer.
  • shutter glasses alternately provide the left and right eyes with image sequences.
  • the object on which the present invention is based is to provide a display device of the type mentioned at the outset with which three-dimensional virtual images can be generated in a technically simple manner.
  • the display device has a projector with an optical device in which auto-stereoscopic beam guidance takes place.
  • autostereoscopic beam steering the propagation of light of different image content is separated and forwarded in a spatially offset manner.
  • this process is preferably carried out by a corresponding optical unit, which is arranged between an imaging device (display) and a beam-shaping lens.
  • a stereoscopic beam steering creates a three-dimensional image for the observer.
  • an imaging device which can preferably be irradiated is provided within the optical device and displays the image information alternately, for example alternatingly, preferably line-by-line or column-by-column.

  • the mask itself borders on a glass pane serving as a support.
  • This glass can have optical correction layers - e.g. in the form of foils - and can thus correct optical distortions.

  • the LED light source 2 is followed by a diffuser 3, which ensures a homogeneous mixing and distribution of the light.
  • a collimator 4 follows in the beam path, which ensures that the mixed and distributed light is thrown approximately parallel onto a downstream transmissive display 5.
  • the display alternately shows the optical information of an image consisting of at least two image parts in a column-like manner.
  • a mask 6 delimits the columns from one another, so that the image information for the right and left eyes reaches a prismatic glass 8 arranged after the mask 6, offset separately.
  • the prism glass 8 shapes the beam path 9 in such a way that an angle of spread corresponding to the distance between the eyes of an observer is created between the light beam of the two display images.
  • the spatially spread light beams of both parts of the image hit the windshield after leaving a projector according to FIG. 1, which acts here as a combiner 13.
