  • Protective coating materials for electrochromic devices
    Patent number: 6261641
    Abstract: Polymeric coating materials used to protect electrochromic devices from environmental and mechanical damage arc provided. The protective polymeric coating materials are physically, chemically and optically compatible with the electrochromic cell layers of electrochromic devices. The polymeric coating materials are polymers having generic polymer back-bones selected from the group of polyimides, polybenzimidazoles, polybenzothiazoles, polybenzoxazoles, poly(phenylene ethers), polyquinolines, polycarbonates, and polysulfones.
    Type: Grant
    Filed: November 4, 1999
    Date of Patent: July 17, 2001
    Assignee: Optical Coating Laboratory, Inc.
    Inventors: Jerry Zieba, Curtis Ross Hruska, Steven P. Sapers, Michael J. Cumbo, Nada O. O'Brien

  • Electrochromic device manufacturing process
    Patent number: 5724175
    Abstract: The present invention is directed to method for manufacturing electrochromic devices using laser ablation techniques. More specifically, the present invention uses laser ablation to provide a simple, noncontact method of patterning electrochromic devices to a controlled depth, to form an electrochromically active area. Furthermore, laser patterning is conducive to the formation of multiple electrochromic devices on a single substrate.
