More Information
Summary:An optical display device includes a plurality of emitters configured to emit electromagnetic radiation in a main emission direction and at least one optical modulation unit which has an adjustable focal length. The emitters are arranged in a main plane and are separately controllable from one another. The optical modulation unit is arranged downstream of the emitters in the main emission direction. Images of the emitters are generated by means of the optical modulation unit, the images of the emitters each having a distance from the main plane which can be predetermined by means of the adjustable focal length. Methods of operating an optical display device are also disclosed.
