Abstract

A method for presenting image content in two operating modes, B1 for a viewing mode with a restricted viewing angle, and B2 for a viewing mode with an unrestricted viewing angle, comprising: providing a first image generator radiating image content into a restricted viewing angle; providing a second image generator radiating image content into an unrestricted viewing angle, wherein the second generator is in front of the first, and is partially transparent to light from the first, and deflects, on at least 50% of its surface, at least 90% of the light passed by it, by maximally 10°; switching on the first generator to start mode B1, wherein the second generator is switched to a transparent state and scatters only a negligible portion of light from the first generator, to retain the restricted viewing angle; and switching on the second generator to start mode B2.
