摘要： A optical filter comprising a variable transmittance layer having a first spectrum in a dark state, and a second spectrum in a faded state; and a color balancing layer having a third spectrum; each of the first, second and third spectra comprising a visible portion; the first and third spectra combining to provide a dark state spectrum approximating a dark state target color; and the second and third spectra combining to provide a fades state spectrum approximating a faded state target colour. The optical filter may further comprise a light attenuating layer. The optical filter may further comprise part of a laminated glass.

摘要： A layered structure for a variable transmittance optical filter includes a transparent conductive electrode and a substrate layer. The transparent conductive electrode includes a charge injection layer that has one or more of gold, molybdenum, palladium, reduced graphene oxide, amorphous indium gallium zinc oxide (a-IGZO), platinum, nickel, ruthenium, rhodium, asmium, selenium, tellurium, graphene, and carbon nanotubes. The substrate layer includes a transparent substrate and is positioned relative to the transparent conductive electrode such that light passing through the transparent conductive electrode passes through the substrate layer.
