Alignment of Ferroelectric Liquid Crystals with Photoanisotropic Azodye Aligning Layers

چکیده
The photo-induced alignment quality of a ferroelectric liquid crystas (FLC) onto a photochemical stable azodye film was studied for various procedures of the azodye film photo-treatment and the FLC structure. The alignment quality of FLC depends mainly on the order parameter of the azodye film, however the structure of FLC layer is also important. So, the photo-aligned deformed helix ferroelectric (DHF) liquid crystal exhibits the contrast ratio CR>500:1, while for the helix free FLC the contrast ratio CR>1500:1.

Photoalignment of Ferroelectric Liquid Crystals by Azodye Layers
The photoinduced alignment of ferroelectric liquid crystals (FLCs) onto photochemically stable azo-dye films was studied. The alignment quality of FLC display cells depends mainly on the difference between the FLC surface energy and the aligning substrates surface energy; however, the structure and thickness of FLC layers are also important. The effect of the thickness of photoaligning azodye l...

Effect of photoaligning azo-dye layers thickness on the alignment quality and multiplex operation of passively addressed ferroelectric liquid crystal (FLC) 1.5μm display cells has been investigated. An optimal (about 3~5 nm) azo-dye layer thickness, that provides both the highest multiplex operation steadiness and the best contrast ratio of FLC display cells was found.
متن کاملSolitary wave propagation in surface stabilized ferroelectric liquid crystal cells
Solitary wave propagation in surface stabilized ferroelectric liquid crystal cells controlled by surface anchoring of the alignment layers is investigated for different conditions of alignment on the two opposite surfaces. We show that the critical field Ec, where the speed of the solitary wave becomes zero, is finite for asymmetric alignment on two surfaces. We also show that the polar anchori...
متن کاملProperties and Applications of Ferroelectric Liquid Crystals
The ferroelectric modes of liquid crystals which allow for easy reorientation of the direction of polarization make liquid crystals an attractive element to use for applications such as optical storage, and optical switching. Three schemes for achieving ferroelectricity are discussed: chiral smectic alignment, achiral “banana-shaped” smectic alignment, and the nematic phase that comes from stro...
متن کامل37.3: Optimization of Photo-Aligned Asymmetric Ferroelectric Liquid Crystal Display Performance: Effect of Planar Layer
Photo-aligned ferroelectric liquid crystal (FLC) display reveals a perfect alignment in case of asymmetric boundary conditions, when the competition in aligning action of two solid surfaces is avoided. In this case a stable uniform photo-alignment on one of the cell substrates spreads out to the other, which is prepared to sustain planar alignment with a degenerate azimuthal direction. In the p...
