Exploring Motion Reversal in Polymer Cholesteric-Liquid-Crystal Devices

OSTI ID:896265
Polymer cholesteric-liquid-crystal (PCLC) flakes suspended in a fluid are used as the active medium in a novel particle-based, electro-optic technology. The motion of PCLC flakes is controlled with an electric field so that PCLC flake devices are brightly reflective in their “off” state and appear dark when an electric field is applied, causing the flakes to reorient 90º. We seek to control flake orientation by designing waveforms that follow the initial drive voltage. Shaped pulses were investigated to accelerate flake relaxation.
