Abstract: An apparatus for generating a virtual image having a display element for generating an image, an optical waveguide for expanding an exit pupil, and an anti-glare element arranged downstream of the optical waveguide in the beam path, wherein the anti-glare element is a shutter that has a plurality of slats which, in their end regions, have flat reinforcing elements which protrude beyond the slats is disclosed.

Abstract: A device for generating a virtual image comprising a display element for generating an image, an optical waveguide for expanding an exit pupil and an anti-glare element arranged downstream of the optical waveguide in the beam path, wherein the anti-glare element is a shutter which has a plurality of slats wherein the slats come to rest in each case on a slant of at least one one-piece spring is disclosed.

Abstract: A device for generating a virtual image comprising a display element for generating an image, an optical waveguide for expanding an exit pupil, and an antiglare element, which is arranged after the optical waveguide in a beam path and is configured as a shutter comprising slats, wherein the slats are arranged variably in their setting angle during operation is disclosed.

Abstract: The disclosure relates to an optical waveguide for a display device and to a method for producing such an optical waveguide. The optical waveguide has a substrate on which a hologram layer is arranged. A cover layer includes a light-transmissive material that has been subjected to a curing process is arranged on the hologram layer. The substrate can consist of glass. Alternatively, the substrate likewise consists of a light-transmissive material that has been subjected to a curing process.

Abstract: A method for exactly aligning at least two holograms arranged in optical waveguides with respect to one another includes writing a first hologram and a first mark in a first optical waveguide. The method also includes writing a second hologram and a second mark in a second optical waveguide. The method further includes positioning the first optical waveguide and the second optical waveguide with respect to one another. The method also includes illuminating the first mark and the second mark. A pattern occurring during the illumination after passing the first mark and the second mark is detected. The method further includes changing the position of one of the optical waveguides until the detected pattern matches a specified pattern.
