Abstract

Bistable or multi-stable displays have been attracting a great deal of attention owing to the demand for energy-efficient mobile devices as well as the arousal of environmental concerns. One of the candidates with the merit of bistability is the bistable chiral tilted-homeotropic nematic mode which can easily switch between the twist-like and homeotropic-like stable states. Introducing dichroic dyes into this optically bistable system, we demonstrated a bistable-liquid-crystal-display mode without the need of polarizers. A proper mixture of dichroic dyes of blue, orange, red, yellow and cyan colors that evenly cover the visible spectral range was considered and the electro-optical performance of the resulting device was addressed in this study.
