  • Shatter-proof liquid crystal panel with infrared filtering properties
    Patent number: 4749261
    Abstract: Liquid crystal material is operable to modulate light transmitted through a panel such as a sunroof, window or partition. The panel may have safety glazing properties. The panel may also include means for reflecting infrared energy. The liquid crystal material includes operationally nematic liquid crystal having positive dielectric anisotropy and a containment medium for containing plural volumes of the liquid crystal material. The panel includes transparent surfaces with the liquid crystal material disposed therebetween and selectively operable primarily to transmit or primarily to scatter light. The liquid crystal material may alternatively include volumes of liquid crystal with a pleochroic dye in a containment medium for selectively attenuating light.
