VARIABLE REFLECTANCE MIRROR SYSTEM

Abstract:

A window is provided that includes a first substrate, a second substrate spaced apart from the first substrate, an intermediate substrate between the first and second substrate and having a first transparent electrode on a surface proximal to the first substrate and second transparent electrode on a surface proximal to the second substrate, a first electrode on a surface of the first substrate proximal to the intermediate substrate, a second electrode on a surface of the second substrate proximal to the intermediate substrate, a light absorbing layer comprising an electrochromic medium between the first substrate and the intermediate substrate, and a light scattering layer comprising a liquid crystal material between the intermediate substrate and the second substrate.
