BISTABLE LIQUID-CRYSTAL UNITS Russian patent published in 2005 - IPC

FIELD: measurement technology.

SUBSTANCE: at least two stable or metastable ordering of liquid crystal are realized. Switching aid which causes the switching of liquid crystal material between switches has aid intended for optical illumination of the device. Device can provide the supply of linear polarized light for inducing torsion in liquid crystal. Alternatively ordering of liquid crystal can be switched by means of aid for supplying second energy, for example, electric field. In this case light serves to generate heat which helps to switching. One or both energy sources can be used locally for switching chosen areas or pixels. Energy levels on bistable substrate can be controlled by using oligomer adding (slippery surface).

EFFECT: improved efficiency of operation.
