Abstract: A projection display device includes an imaging unit; a planar waveguide with a light decoupling face for a light beam bundle produced by the imaging unit; an at least partially transparent reflection plate arranged in the field of view of a user and configured to reflect a light beam bundle decoupled from the waveguide to an eyebox predetermined for the user's eyes; an eye-tracking device configured to determine an eyebox window which is currently occupied by the user's eyes; and a dynamic scattered light absorber, which, to shadow the light decoupling face in a surface portion which is dynamically adjustable depending on a signal of the eye-tracking device and which extends starting from at least one of the edges of the light decoupling surface, is configured to at least partially limit the decoupled light beam bundle to the current eyebox window.

Abstract: A waveguide display assembly includes a flat waveguide; a passage filter layer, which is divided into a plurality of area segments, which can be switched to light passage independently of each other; an image-generating unit, which is configured to generate different 2D images, each of which is intended only for one eye of a user for autostereoscopic 3D presentation, and to couple the 2D images into the waveguide in the form of collimated light beams, the propagation directions of which correspond to individual pixels; and a control unit, which is configured to control the image-generating unit and the passage filter layer such that only one or a subset of the area segments is switched to light passage at a time and, synchronously therewith, the image-generating unit generates only one image area segment of the 2D image intended for one eye of the user.

Abstract: A windscreen display system for a motor vehicle has a head-up display device. The head-up display device has a projection device for emitting a projection light beam with a first item of image information towards a display region of a windscreen so that the information is reflected there and can be perceived in an eye region, and a transparent covering for protecting the projection device, the covering having a cover pane and an antireflection layer applied to one or both sides.

Abstract: A head-up display system for a motor vehicle includes a projection unit for providing a display image; a transparent holographic light guide display panel with a display surface in order to output a display image coupled into the display panel via a coupling-in region on a display surface, and a light guide which runs in a non-linear manner in order to guide a display image from the projection unit to the coupling-in region of the display panel.

Abstract: A head-up display system for a motor vehicle includes a projection unit for providing a display image; a transparent, holographic optical fiber display panel for outputting, on a display surface, a display image that is coupled into the display panel via a coupling-in region; and a guide device designed to move the display panel between an operational position and a parked position.
