Abstract

The use of a holographic video screen which appears black, gray or colored in ambient light as the display surface in a vehicle, wherein a driver can view the screen while driving without taking his eyes of the road. Additionally, the display system containing such a video screen permits the projection and viewing of multiple images on a single screen.
