Method of varying wavelengths of liquid crystals

摘要

The present invention relates to a method of generating a second peak wavelength of reflected light from a cholesteric liquid crystal having a first peak wavelength of reflected light comprising by exposing or conditioning the cholesteric liquid crystal to a high temperature or a high humidity. The invention also relates to an electrically modulated imaging layer and a display containing a liquid crystal material that has conditioned and unconditioned forms, wherein the unconditioned form of liquid crystal material reflects a first wavelength of light and wherein the conditioned form of liquid crystal material reflects a second wavelength of light.
