Page "Liquid crystal display" Paragraph 67

Several bistable technologies, like the 360 ° BTN and the bistable cholesteric, depend mainly on the bulk properties of the liquid crystal ( LC ) and use standard strong anchoring, with alignment films and LC mixtures similar to the traditional monostable materials.

Other bistable technologies, e. g., BiNem ® technology, are based mainly on the surface properties and need specific weak anchoring materials.
