Abstract

At least one electronic display has first and second mirrors separated by a distance. The two mirrors are arranged such that they at least partially overlap in a projection view of both mirrors. An intermediate space is formed in the overlap region between the mirrors. The at least one electronic display is part of a display apparatus having at least one light source emitting light into the intermediate space that is reflectable multiple times by the mirrors to generate an infinity mirror effect, resulting in the generation of an image having a light pattern that appears with an optical depth effect in an image plane of the display apparatus.
