ABSTRACT:
Electro optic devices incorporating an improved configuration of elements which dramatically reduces light scattering and haziness with relatively inexpensive coated glass. The devices are liquid or gel containing electro optic devices, such as an electrochromic automatic rearview mirror for automotive vehicles, which has for at least one of its walls a sheet of glass coated with a transparent conductive coating. The combination of the coated glass, which has a tendency to have an optically rough surface, and the liquid or gel electro optic material reduces the scattering of any incident light by wetting out the rough optical surface of the coated glass, thereby improving the optical quality. The coated glass scatters between 0.2 and 4.0% of visible white light prior to assembly into the device.
