High Birefringence and Low Viscosity Liquid Crystals with Negative Dielectric Anisotropy
نویسندگان
چکیده
Fast response time is critical for reducing the image blurs in LCD TVs. A straightforward approach is to use thin cell with a high birefringence and low viscosity liquid crystal material. We have synthesized and evaluated the physical properties of some high birefringence, laterally difluorinated terphenyl compounds and mixtures. These mixtures exhibit a high birefringence (Dn 0.24) in the visible spectral range and a relatively low viscosity. When doped in commercial mixtures, the difluoro terphenyl compounds enhance the mixture’s birefringence while causing almost no penalty to the rotational viscosity. These mixtures are particularly attractive for thin cell LCDs to achieve fast response time.

متن کاملHigh Performance Negative Dielectric Anisotropy Liquid Crystals for Display Applications
We review recent progress in the development of high birefringence (Δn ≥ 0.12) negative dielectric anisotropy (Δε < 0) liquid crystals (LCs) for direct-view and projection displays. For mobile displays, our UCF-N2 (low viscosity, negative Δε, high Δn) based homogeneous alignment fringe-field switching (called n-FFS) mode exhibits superior performance to p-FFS in transmittance, single gamma curv...

The synthesis and characterization of new 2,2-difluorovinyloxyl terminated tolane liquid crystals are reported. The mesomorphic properties, mid-wave infrared (MWIR) absorption and birefringence were investigated. The results show that these materials exhibit low absorption loss, a wide nematic phase range, a low melting point and high birefringence. The influences of fluorine substitution and t...
