Abstract: The disclosed subject matter provides a chiral host-guest composition for a ferroelectric liquid crystal mixture, the host-guest composition comprising a chiral guest compound and an achiral host compound, wherein the host-guest composition induces a greater degree of polarization in the liquid crystal mixture than is induced in the mixture with a comparable amount of the chiral guest compound in the absence of the achiral host compound. The chiral guest is a fluorinated compound comprising a aryl or heteroaryl core substituted with an alkyl chain, wherein the alkyl chain includes one or more fluorine atoms, each fluorine atom being bonded to a chiral carbon atom. The achiral host possesses a central thiadiazole core, with at least one aryl/heteroaryl wing, further substituted with alkyl or alkoxy groups.

Abstract: Devices and methods are disclosed for improving image quality in a display system. The devices and methods adjust the display optical states based on the input image data. The devices and methods may compensate for temporal variation of the optical states in a display panel arrangement having a liquid crystal and an insulating layer due to a net DC field across the liquid crystal. The variation in optical states may be variation between the position of the optic axis of the liquid crystal for a zero net DC field drive waveform and a drive waveform with a net DC field across the liquid crystal. The variation of the optic axis of the liquid crystal may be due to ionic charge movement through the liquid crystal. The display panel arrangement may have a decay time constant of the liquid crystal and the insulating layer less than a maximum time that is visually acceptable for image sticking to persist on the display panel.

Abstract: Electronic apparatus, systems, and methods to operate a liquid crystal display provide a mechanism that can be used to address image sticking on the display.

Additional apparatus, systems, and methods are disclosed.

Abstract: The invention provides cross-linked lyotropic liquid crystal (LLC) copolymers having ordered nanometer-sized pores lined with functional groups. The copolymers are formed by copolymerizing LLC monomers with strong LLC character and functionalized monomers with no or weak LLC character to form an LLC phase. Both the LLC monomers and the functionalized monomers contain hydrogen-bonding groups and hydrogen-bonding is believed to assist in the formation of the LLC phase of the blended mixture. Different classes of functional groups useful for the invention include, but are not limited to, acidic groups, basic groups, catalytic groups, oxidizing agents, reducing agents, polymerization initiators, binding agents, optically active groups, and electrically active groups. The invention also provides methods for making the cross-linked LLC copolymers of the invention.
