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.
