Method and arrangement for optically representing information

A method and an arrangement for optically representing information on a transparent projection surface using several projection modules and using through-light projection. The method and arrangement are both cost effective and ensures that an observer viewing even a large display of information is provided with a bright, contrast, homogeneous image. Each projection module is formed of a light source with a divergent beam radiating through a controllable light valve and a projection surface arranged behind it. The distance between the light valve and the projection surface is chosen in such a way that the image parts projected by adjacent modules border gaplessly to each other on the projection surface.
