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 …
