1. A method for sealing an electrochromic device, wherein said method comprises the steps of:

  • (a) positioning a sealing means onto the interior face of a first substrate towards the peripheral edge thereof;

    (b) dispensing media onto said first substrate having said sealing means positioned thereon;

    (c) positioning a second substrate in spaced-apart relationship with said first substrate so that said sealing means is positioned therebetween and said media is contained within a cavity created thereby;

    (d) displacing said media throughout said cavity and filling said cavity therewith;

    (e) applying pressure to said first substrate and said second substrate such that said first substrate and said second substrate are pressed toward one another; and

    (f) heating the assembly created by steps (a)-(e) such that said sealing means adheres to the interior faces of said first substrate and said second substrates while sealingly containing said media within said cavity.
