First Claim
1. 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.

Abstract
A method for providing preferential coloring to a portion of an electrochromic window assembly, includes the steps of providing an electrochromic window assembly comprising first and second spaced apart transparent substrates defining a chamber therebetween, the first transparent substrate having a first conductive coating and the second transparent substrate having a second conductive coating, the chamber containing an electrochromic medium capable of coloring upon application of electrical potential thereto to provide reduced luminous transmittance; electrically connecting a plurality of first spaced facilities to the first conductive coating for providing the electrical potential to the first conductive coating; electrically connecting a plurality of second spaced facilities to the second conductive coating for providing the electrical potential to the second conductive coating; and applying an electrical current to selected ones of the plurality of first spaced facilities and to selected ones of the plurality of second spaced facilities to establish the electrical potential through a selected portion of the electrochromic medium such that the selected portion changes color and reduces its luminous transmittance.
