An LC phase modulator with a single-layer multi-microdomain orthogonal twisted (MMOT) structure is proposed, which may achieve good polarization independence and low loss in different phase depths. A light-controlled azimuth angle (LCAA) process based on the rotation effect of cholesteric liquid crystal is developed for the fabrication of the single-layer MMOT structure.

An optical coding in extra-large-pitch CLCs is fulfilled by in-plane optically re-orientating the near-slide LCs. And the encoded words or images in transparent CLCs also show high temporal and thermal stability. The pitch modulation of CLCs is much simplified and shows potential application in information encryption.

This study presents the development of ultra-thin azo-dye polarizers, notable for their minimal thickness (100-300 nm) and superior optical performance, with dichroic ratios exceeding 200:1 and extinction ratios above 4,000. Utilizing cost-effective solution-processing methods, the high-performance polarizers are fabricated and the optimal experimental conditions for peak efficacy are determined.
P.193 - Ring-Shaped Circular-Patch Liquid-Crystal Display Structure Based on Fringe-Field Effect
-

-
A ring-shaped electrode with negative dielectric nematic material is studied. Finite-element simulation and tests have verified the electric field strength, transmittance, and contrast of a 2 x 2 matrix cell. This new structure has significant potential for application in the display field.
