P‐144: Electrooptic Response of FLC: Effect of Alignment Materials

Abstract

In this paper, parameters of ferroelectric liquid crystals (FLC) with different alignment materials, which include Nylon 6 with rubbing method, photoaligned azo‐dye layer SD1 and new photosensitive material from DIC, were investigated. The effects of alignment layer on contrast ratio, response time and switching of FLC are provided. Asymmetric boundary conditions, with only one of ITO surfaces is covered with the aligning layer while the other one is not, have been used for providing both high contrast ratio and defect free orientation. It is indicated that SD1 is suitable for FLC alignment, with which switching time of 65μs and contrast of 500:1 are obtained at room temperature, and switching time decreases with higher temperature.

P.83: ESHFLC Field‐Sequential Color Displays

“…An extensive work studying optical and electrooptical response of ferroelectric liquid crystal (FLC), as well as developing new FLC materials with advanced surface alignment was made [2]. One of the possibilities is a polymer stabilized FLC to enable monostable V-shape switching (PSV-FLCD) [3].…”

“…An extensive work studying optical and electrooptical response of ferroelectric liquid crystal (FLC), as well as developing new FLC materials with advanced surface alignment was made [1]. The new photoalignment materials potentially capable of being used in photo-aligning technology for LCDs were developed [2].…”
