Patent ID: 7130101

Claim:
A method for providing uniform coloring to an electrochromic window assembly comprising: providing an electrochromic window assembly comprising first and second spaced apart transparent substrates defining a chamber therebetween, said first transparent substrate having a first conductive coating and said second transparent substrate having a second conductive coating, said chamber containing an electrochromic medium capable of coloring upon application of electrical potential thereto to provide reduced luminous transmittance; applying an electrical current to opposing ends of said first conductive coating and to opposing ends of said second conductive coating to establish said electrical potential through said electrochromic medium, said opposing ends of said first conductive coating and said second conductive coating being spaced from each other; and positioning a plurality of spaced facilities along at least one of said opposing ends of said first or second transparent substrates in electrical contact with said first or second conductive coating, respectively, for providing said electrical current, wherein said coloring of said electrochromic medium is uniform.
