  • Patent number: 10871694
    Abstract: A bistable cholesteric liquid crystal switchable window has two stable states in the absence of an applied voltage. A first stable state is a planar state which is transparent or reflective for visible light. A second stable state is a focal conic state which is opaque for visible light. The window can be switched from the first stable state to the second stable state via a first voltage pulse and from the second stable state to the first stable state via a second voltage pulse. The first voltage pulse and the second voltage pulse may have the same frequency.
