Graphic Interpretations

                    Graphic A                                         Graphic B

Graphics A & B:  Cross section of a liquid crystal panel showing the thin matrix of polymer and liquid crystals sandwiched between two pieces of glass.

Graphic A: When the power is off, the liquid crystal particles are randomly oriented.  As light waves pass through the panel, they are randomly reflected and scattered creating a grey translucent fog.

Graphic B:  When electricity is applied to the panel, the liquid crystal molecules line up in parallel fashion allowing all the light to pass uninterrupted creating a clear transparent window.

                   Graphic C                                         Graphic D

Graphics C & D:  Existing technology designed to control light intensity.

Graphic C:  Most ornamental plants would be damaged by the full intensity of the sun.  The LC panels can adjust to a foggy translucent state and reduce the light intensity by up to 50%. 

Graphic D:  Natural light is reduced as clouds pass throughout the day or when winter arrives.  The LC panels will adjust to a clear transparent state to allow the maximum amount of available light to enter thus optimizing plant growth.

                   Graphic E                                         Graphic F

Graphics E & F:  Development of the next generation of liquid crystal panels designed to control and optimize wavelength, as well as light intensity.

Graphic E: The light spectrum consists of ultraviolet, visible and infra red waves.  Light in the infra-red spectrum is often considered “junk heat” having temperatures over 105 degrees.  In the summer, the liquid crystal panels will adjust to block the excessive infra-red heat waves from entering the greenhouse.  This allows the greenhouse environment to remain cooler while still permitting visible and UV light to enter for successful plant growth.

Graphic F: During the winter this infra-red spectrum of light is allowed to enter and warm the greenhouse, thus reducing utility costs.

                                Graphic G

Graphic G: A cross section of the liquid crystal glass panel reveals its multilayer construction.  The central core (A) is composed of liquid crystals suspended in a polyresin matrix.  This core is sandwiched between a polymer film (B) that is covered with a specialized voltage conductive coating.  These layers are sealed between two ultraviolet resistant protective films (C).  Finally, the entire assembly is laminated between two pieces of glass (D) forming the strong stable liquid crystal panel.
