Shatter-proof liquid crystal panel with infrared filtering properties
First Claim
1. A liquid crystal panel, comprising:
- first and second transparent surfaces through which visible light incident thereon may be transmitted;
liquid crystal means located between said transparent surfaces for determining the amount of light transmitted through said panel;
said liquid crystal means including operationally nematic liquid crystal having positive dielectric anisotropy and a containment medium means for containing plural volumes of said liquid crystal; and
means for reducing the amount of infrared energy transmitted through said panel.

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.
