Journal ArticleDOI
Optical characteristics of a guest-host reflective liquid-crystal display with a phase compensator but no polarizing sheet and with positive image contrast
TL;DR: In this article, a phase compensator was used to obtain high reflectance and image contrast and also a moderate degree of multiplexing for a guest-host reflective liquid-crystal display.
Journal ArticleDOI
Kerr effect and Kerr constant enhancement in vertically aligned deformed helix ferroelectric liquid crystals
TL;DR: In this article, a vertically aligned deformed helix ferroelectric liquid crystal (VADHFLC) was proposed to achieve a 2π modulation by a small efficient electric field with a fast response around 100 μs.
