ABSTRACT:
A generally planar layer of a polymer dispersed liquid crystal (PDLC) material is sandwiched between a pair of opposing interior surfaces of first and second substrates, at least one of which is transparent. Electrode layers are disposed on the exterior surfaces of the substrates, with the electrode layer overlying the transparent substrate being made of a substantially transparent electrically conductive material such as Indium Tin Oxide (ITO). The first and second electrode layers are configured for receiving a first electrical signal that causes the layer of PDLC material to assume a first optical state selected from the group consisting of transparent and opaque. A plurality of conductors are disposed in the PDLC material and are configured for receiving a second electrical signal that causes the layer of PDLC material to assume a second optical state that is different than the first optical state.
