Patent ID: 8228590

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 first hue (h ab ) when viewed through said electrochromic element in approximately said high transmittance state and a second hue (h ab ′) when viewed through said electrochromic element in approximately said low transmittance state, wherein a change in said first and second hues (Δh ab ) for both first and second primaries is less than approximately 31 degrees.
