Abstract
Energy-efficient display has been drawing much attention in recent years
due to the prevailing of mobile devices as well as the rising environmental
concerns. A chiral nematic system with appropriately configured pre-tilted
angle and pitch length is capable of switching between the twist-like and
homeotropic-like states with the merit of bistability. Introducing dichroic
dyes into this system, we demonstrated a bistable scheme of liquid-crystal
display without the need of polarizers.
