Abstract:
Aglazing, comprising:a) at least one active layer; b) at least one reflecting coating on said active layer; c) two electrically conductive layers; d) two transparent substrates, at least one of which is rigid; and e) a gas layer; wherein the active layer comprises at least one optically variable layer which is an electrically controllable system, which system is a variable light diffusion system, comprising a composite polymer film having embedded therein droplets of liquid crystals, wherein the ordinary index of said liquid crystals, no, is equal to the index of said polymer, np; and wherein the variable light diffusion system is placed between the two electrically conductive layers, and said gas layer is placed between the two transparent substrates.
