44.3: Photo-Aligned Passively Addressed Ferroelectric Liquid Crystal Display Cells: Effect of Aligning Layer Thickness
نویسندگان
چکیده
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.

20.3: Photo-aligned Ferroelectric Liquid Crystal Display with Memorized Gray Scale
The new concept of the passive matrix ferroelectric liquid crystal display (FLCD) with a memorized grey scale is proposed. The physical origin of the gray scale in ferroelectric liquid crystal display is considered. The criterion of reliable bistability is derived dependent on FLC hysteretic behavior in electric field. A new approach for multiplex electronic addressing of the FLCD grey scale is...
متن کاملPhotoalignment 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...

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...

Photoalignment possesses obvious advantages in comparison with the usually “rubbing” treatment of the substrates of liquid crystal display (LCD) cells. The liquid crystal photoalignment is nano-technology, as the thickness of the alignment layer is about 2-15 nm. The application of the photo-alignment and photo-patterning nano technology for the new generation of photonic and display devices wi...
متن کاملAlignment of Ferroelectric Liquid Crystals with Photoanisotropic Azodye Aligning Layers
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 ferroelect...
