  • Patent number: 8446550
    Abstract: An automatic darkening liquid crystal mirror for vehicles, the mirror having a transparent front substrate and a back substrate with a reflective or transflective mirrored coating. The front and back substrates are spaced apart to define a liquid crystal cell between the substrates that is filled with a liquid crystal fluid incorporating a dichroic dye. A conductive thin film is applied onto the interior surface of the front substrate, and the mirrored coating of the back substrate also is conductive. An alignment compound is deposited on opposite sides of and bounding the liquid crystal cell. An electronic control circuit is adapted to apply selectively a voltage signal to the conductive think film and the conductive mirrored coating to affect the transmittance of the liquid crystal fluid, and thereby the darkness of the mirror, in response to light intensity sensed by a headlight sensor coupled to the electronic control circuit.

    Abstract: A variable reflectance vehicular mirror reflective element assembly includes a front substrate, an intermediate substrate and a rear substrate, with a first liquid crystal polarization unit disposed between the rear surface of the front substrate and the front surface of the intermediate substrate and a second liquid crystal polarization unit disposed between the rear surface of the intermediate substrate and the front surface of the rear substrate. When the liquid crystal polarization units are unpowered, the reflective element assembly substantially specularly reflects light incident thereon so as to appear specularly mirror-like to a driver of the vehicle viewing the front surface of the front substrate. When the liquid crystal polarization units are electrically powered, they change from being highly specularly reflective to substantially transmitting visible light therethrough.

  • Publication number: 20100079721
    Abstract: Provided are multilayer laminates having one or more layers comprising twisted nematic liquid crystals and one or more layers of a polymeric sheet. The twisted nematic liquid crystal layers reflect infrared radiation. Thus, the multilayer laminates are useful to reduce the transmission of infrared energy. For example, in some embodiments the multilayer laminates are useful as windows to reduce energy consumption necessary to cool the interior of a structure such as an automobile or building. Preferably, the multilayer laminates retain one or more of the beneficial properties of safety glass. The multilayer laminates may include additional layers such as infrared absorbing layers, half wave plates, and the like, to minimize the transmission of infrared energy. The multilayer laminates may also include further additional layers such as polymeric films, polymeric sheets, rigid sheets, and the like.
