  • Publication number: 20070184284
    Abstract: An exterior electrochromic reflective mirror element for a vehicular exterior rearview mirror assembly comprises an electrochromic cross-linked polymeric solid film disposed between a first substrate and a second substrate. The electrochromic cross-linked polymeric solid film contacts a transparent conductive layer of the first substrate and a conductive layer comprising a metallic reflective layer of the second substrate. A visual indicator display is disposed to the rear of said second substrate and is part of a blind spot detection and display system and is actuated to emit light responsive to a detection of another overtaking vehicle in a side lane. Light emitted by the visual indicator display passes through the second substrate, through the electrochromic cross-linked polymeric solid film and through the first substrate to be viewed by a driver of the vehicle equipped with the exterior electrochromic reflective mirror element.

  • Publication number: 20060028730
    Abstract: An electrochromic rearview mirror element for a motor vehicle comprises a first substantially transparent front substrate having a first and a second surface (and with a substantially transparent conductive electrode on its second surface) and a rear substrate having a third and a fourth surface. The rear substrate is positioned in spaced-apart relationship with the front substrate and with its third surface opposing the second surface of the front substrate. A mirror reflector is disposed on the third surface and a seal is positioned toward a peripheral edge of the substrates forming a cavity therebetween. An electrochromic medium is disposed in the cavity. The mirror reflector preferably comprises a metal layer that reflects at least about 70% of visible light. A display device can be disposed behind the rear substrate.

  • Publication number: 20050079326
    Abstract: An electrochromic mirror device suitable for use in a vehicle comprises a first transparent substrate having a transparent conductive layer on a surface thereof and a second substrate having a conductive layer on a surface thereof. The conductive layer of the first substrate opposes the second conductive layer of the second substrate in a spaced-apart relationship thereby forming an interpane distance between the substrates. A boundary seal is interposed between the first and second substrates spacing apart the substrates and forming a cavity wherein the interpane distance is at least about 10 microns. An electrochromic cross-linked polymeric solid film is disposed within the cavity. The electrochromic cross-linked solid polymeric film is formed from an electrochromic monomer composition that includes at least one cathodic electrochromic compound. The second conductive layer comprises a metallic reflective layer.

  • Patent number: 6620454
    Abstract: Processes for making a transparent substrate having a glare reducing diffuser surface coating on its surface are disclosed to provide a touchscreen or a faceplate such as for attachment to a screen for a cathode ray tube or other display device. Preferably, the faceplate has at least one of a gloss reading of less than about 80 gloss units, and a resolution of at least about 3 lines per millimeter. The method includes coating at least one layer of a precursor solution onto a functional coating provided on at least one surface of the substrate, and firing the layer to form the faceplate having a diffuser surface coating on the functional coated substrate. Preferably, the precursor solution at least comprises a metal oxide precursor dissolved in an organic solvent. Also, the firing preferably occurs at a temperature of at least 250° C. The functional coating is preferably provided as a transparent conductive coating.

  • Patent number: 6440491
    Abstract: Processes for making a transparent substrate having a glare reducing diffuser surface coating on its outer surface are disclosed to provide a faceplate such as for attachment to a screen for a cathode ray tube or other display device. Preferably, the coating has a thickness of less than about 3 microns and/or a gloss less than about 80 gloss units. The method includes spraying a precursor solution onto the substrate to form a preliminary coating, at least partially densifying that preliminary coating, spraying another coating of precursor solution onto the preliminary coating, and firing the coating to form a diffuser surface coating. Alternately, a precursor solution of an inorganic metal oxide dissolved in an organic solvent is sprayed on the substrate and fired at a temperature within the range of from about 250° C. to about 600° C. to form the diffuser surface coating.

  • Patent number: 5233461
    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.
