A LuxVu window is a proprietary blend of Chelix CLCs sandwiched between two sheets of glass. Two clear layers of conductive material on the insides of the glass sheets allows an electric field to control the optical properties of the CLC blend and switch the window quickly and easily between a clear and transparent state.

In the OFF state, when no power is applied to the window, the liquid crystal molecules are oriented in random directions. Light passing through the window is scattered by the molecules, and the window appears milky-white.

When the window is switched ON, the liquid crystals reorient themselves to align parallel to each other and to the electric field. Now, light can pass through the window without being scattered, and the window is clear and transparent.

(This technology is known as polymer stabilized cholesteric texture, or PSCT.)
