Dimmable rear view mirror, particularly for automotive vehicles
First Claim
1. A dimmable rearview mirror, particularly for motor vehicles, comprisinga mirror reflective surface constituting a mirror,a liquid crystal cell covered adjacent a rear side thereof by said reflective surface;
- two polarization filters spaced apart from each other,said liquid-crystal cell being disposed between said two polarization filters,said liquid-crystal cell includes cell glasses, a liquid-crystal substance enclosed by said cell glasses, and electrodes disposed on said cell glasses,said electrodes cover substantially the entire surface of said liquid crystal cell next to said liquid-crystal substance,means including a source of voltage connected to said electrodes for adjusting the degree of reflection of the rearview mirror in the area of the reflective surface,a display surface at least alongside of said reflective surface formed by one part of the liquid-crystal cell for displaying characters and symbols.

Abstract
A dimmable rearview mirror, particularly for motor vehicles comprising a reflective surface, two polarization filters spaced apart from each other and arranged in front of the reflective surface as seen in the direction of observation. A liquid crystal cell is disposed between the two polarization filters and includes cell glasses enclosing a liquid crystal substance. The cell glasses are provided with electrodes, the electrodes surfacewise covering essentially the entire surface of the reflective surface. A switchable and/or variable source of voltage is connected to the electrodes for adjusting the degree of reflection of the rearview mirror.
