Method and display for the presentation of image contents in at least two operation modes

A display screen that is operable in at least two operating modes, namely, a first operating mode for a viewing mode with a restricted viewing angle, and a second operating mode for a viewing mode with an unrestricted viewing angle, comprising:

• a first image generator that radiates image content into the restricted viewing angle;
• a second image generator that radiates image content into the unrestricted viewing angle, wherein the second image generator is arranged in front of the first image generator, as seen in a viewing direction, and is at least partially transparent to light originating from the first image generator, wherein the second image generator is adapted to deflect, on at least 50% of its surface, at least 90% of the light passed by the second image generator, by maximally 10°;
• wherein the first image generator for the first operating mode for the first viewing mode with the restricted viewing angle is configured to be switched on for the viewing mode with the restricted viewing angle, and wherein the second image generator is configured to be switched to a transparent state when the first image generator is switched on for the first viewing mode with the restricted viewing angle and, due to limited scattering properties of the second image generator, scatters only a negligible-portion of the light originating from the first image generator when the light originating from the first image generator passes the second image generator, so that the restricted viewing angle is retained, and
• wherein the second image generator is configured such that at least the second image generator is switched on to start the second operating mode for the viewing mode with the unrestricted viewing angle.
