Twist angle effects on the dynamic response of in-plane-switching liquid crystal displays

Twist angle effect on the response time of in-plane-switching liquid crystal displays are analyzed. We propose a device configuration whose top and bottom boundary liquid crystal layers are symmetric to each other with respect to the electric field direction. The analytical results of this device configuration indicate that the response time is improved at least 4X faster than that of a conventional in-plane-switching twisted-nematic mode and normal in-plane-switching mode.Comment: 12 Pages, 3 Figures. will be appeared in Appl.

Synthesis, mesomorphic and optical properties of isothiocyanatotolanes

The synthesis, mesomorphic properties and UV absorption spectra of laterally fluorine substituted, and the corresponding unsubstituted, 4∞-alkyl-, 4∞-alkoxy-, 4∞-alkylcyclohexyl-, 4∞-alkylbicyclo[2,2,2]octyl-and 4∞-alkylcyclohexylethyl-4-isothiocyanatotolanes are described. Multicomponent broad range nematic mixtures with birefringence values higher than 0.4 and moderate viscosities are developed
