Abstract
The method for sealing electrochromic devices disclosed in the present invention allows the cell cavity of a device to be established and filled with media at substantially the same time, without requiring spacer beads, fill holes and the like to complete the assembly. Moreover, the method of the present invention allows the cell cavity to be filled without accurately pre-measuring the media. Further, the sealing means used herein is constructed of a thermoplastic material that is inert to, and compatible with, the media commonly used and which forms an integral seal, even while in intimate contact with the media in the cell cavity.
