Alignment Optimization on Gen. 4.5 G for High-framerate Ultra-high-resolution Ferroelectric Liquid Crystal Displays

Abstract

We achieve high-framerate (< 100 μs) high-contrast-ratio ferroelectric liquid crystal displays (FLCD) on Gen 4.5. Innovatively, a new polyimide (PI) that is suitable for ferroelectric liquid crystal (FLC) alignment is synthesized and tested on the production line. It replaces Nylon 6 (N6), which was the barrier to the commercialization of FLCD. Moreover, a new FLC is synthesized to match requirements in mass production. Additionally, various materials were studied to investigate the surface energy and relative performance. It is not only proof of the feasibility on the production line, but also a significant step towards the commercialization of field-sequential-color high-resolution FLCDs.
