Ferroelectric Liquid Crystals with High Spontaneous Polarization

Ferroelectric liquid crystals

2014 A general symmetry argument is presented, and experiments on newly synthesized p-decyloxybenzylidene p’-amino 2-methyl butyl cinnamate are described, demonstrating that chiral smectic C and H liquid crystals are ferroelectric. Some of the properties of this new class of ferroelectrics are discussed. In spite of speculation on the possibility of ferroelectric liquid crystalline phases [1], ...

Multiprimary color display for liquid crystal display projectors using diffraction grating

Takeyuki Ajito Takashi Obi Masahiro Yamaguchi Nagaaki Ohyama Tokyo Institute of Technology Imaging Science and Engineering Laboratory 4259 Nagatsuta, Midori-ku Yokohama, 226-8503 Japan E-mail: [email protected] Abstract. To reproduce the natural color of an object through color imaging systems, the range of the reproducible color, i.e., the color gamut, of the color display devices must be...

High 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...

Linear electroclinic coupling in ferroelectric liquid crystals

We report a study of the electrodmic coupling (soft mode), close to the smectic A to smectic C* phase transition in several chiral compounds The main charactenstic of the technique used is to measure both optical and dielectric quantities on a single sample This
