1. An information display system for at least one person, comprising:
- a first display unit for presentation of information on a windshield of a vehicle as a head-up display;
a second display unit for the presentation of information on the dashboard of the vehicle;
optical means that adjust the presentation in a direction of view of the person, wherein an illumination beam path is adapted to the direction of view of the person;
a Fresnel prism displaceable in the illumination beam path, the Fresnel Prism deflecting the illumination beam path, whereby parts of the information are selectively presented graduation-free in the first display unit and the second display unit.

Abstract
An information display system having an output display for presenting information. Optical means are provided that deflect an illumination beam path into the field of view of the observer. Further, a subdividable output display is created that makes it possible to partly obtain information in a vehicle via a head-up display and partly via a traditional or back-projection display. Given seats arranged in rows, for example in airplanes or buses, back rests of preceding seats contain an output display and a communication interface to the seat of the viewer.
