Abstract:
1. An electrochromic device comprising: a first working electrode comprising a first transmissive material and a first electrochromic material; a second working electrode comprising a second material and a second electrochromic material, wherein said second material can be the same or different than said first transmissive material; at least one counter electrode; and electrolyte comprising material dispersed between and contacting said counter electrode and said working electrodes, wherein said counter electrode is transmissive and sandwiched between said working electrodes, wherein said second working electrode is a reflective conducting material or comprises a transparent conductive material whose surface opposite said counter electrode contacts a reflective material and said electrochromic material is disposed on the surface directed toward said counter electrode, wherein electrical potentials are independently applied between said first working electrode and said counter electrode and said second working electrode and said counter electrode, and wherein color observed from said device is derived by combination of colors of said working electrodes.
