Patent ID: 8508832

Claim:
An electrochromic system comprising: an electrochromic element comprising: a front element comprising first and second surfaces; a rear element comprising third and fourth surfaces, wherein said front and rear elements are sealably bonded together in a spaced-apart relationship to define a chamber, such that said second surface and said third surface face one another; a transparent first electrode comprising a layer of conductive material carried on said second surface; an electrochromic medium contained in said chamber, wherein said electrochromic medium is adapted to be in at least a high transmittance state and a low transmittance state; and an at least partially transmissive, partially reflective second electrode; and a display device in optical communication with said electrochromic element, said display device comprising: at least one light source; and said display device being configured to emit at least a first primary and a second primary, and said first and second primaries each having a color (u′,v′) when viewed through said electrochromic element in approximately said high state and a second color (u′,v′) when viewed through said electrochromic element in approximately said low transmittance state, and a difference in said first and second colors (ΔE u′,v′ ) for said first and second primaries is less than approximately 0.06.
