Photoaligning and Photopatterning—A New Challenge in Liquid Crystal Photonics
Photoalignment possesses obvious advantages in comparison with the usually “rubbing” treatment of the substrates of liquid crystal display (LCD) cells. The application of the photoalignment and photopatterning nanotechnology for the new generation of photonic and display devices will be reviewed.
متن کاملPatterned photoresist spacers and photo-induced alignment coatings for liquid crystal waveplates and polarizers
The OMEGA laser system uses waveplates and polarizers to alter the polarization of the laser light. Both devices are formed using two glass substrates that contain alignment layers and are separated by vacuum-deposited thin-film spacers and filled with liquid crystals (LCs). Vacuum deposition of thin-film spacers is time-consuming and requires the use of expensive equipment. In this study, spac...
متن کاملPolar anchoring energy measurement of vertically aligned liquid-crystal cells
An electric-field method is developed for measuring the polar anchoring energy of vertically aligned nematic liquid-crystal cells. Both theoretical analyses and confirming experimental results are presented. Vertically aligned liquid-crystal cells with buffed polyimide alignment layers are used to investigate the measurement techniques. Based on the voltage-dependent transmittance of the liquid...
متن کاملPhotoalignment possesses obvious advantages in comparison with the usually “rubbing” treatment of the substrates of liquid crystal display (LCD) cells
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 کامل44.3: Photo-Aligned Passively Addressed Ferroelectric Liquid Crystal Display Cells: Effect of Aligning Layer Thickness
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.
