METHOD FOR PROTECTING AND CONCEALING SEAL IN ELECTRO-OPTIC WINDOW

Abstract:

An electro-optic window comprises a first substrate; an electro-optic element generally parallel to the first substrate, the electro-optic element comprising: a second substrate; a third substrate generally parallel to the second substrate; a sealing member disposed along at least a portion of a perimeter of one of the second and third substrates and extending therebetween; and a cavity defined between the second and third substrates. The sealing member defines the sidewalls of the cavity. A first layer of film having a perimeter portion and a central portion is disposed between at least a portion of the first and second substrates, and may be coextensive with the sealing member.
