Sexual reflex, for multiple colour low-power consumption reflection-type liquid crystal display, only when optical activity and the cholesteric crystal layer one of incident illumination
Just reflected when cause and wavelength meet Bragge formula, i.e. the wavelength X of incident illumination and the pitch P of liquid crystal material and mean refractive indexIt is directly proportional:
(Bragge formula)
The pitch P of liquid crystal material of cholesteric phase and the relation of chiral agent concentration Xc be:
Wherein HTP is the distortion power constant of chiral agent, can be worth chirality component and at liquid crystal by the different HTP of regulation
The content of material changes pitch and reflection wavelength.
Reflection light is circularly polarized light, and optical activity and the optically uniform of cholesteric crystal layer, with cholesteric crystal layer optically-active
The light then permeate crystal layer that property is contrary enters next layer, is unsatisfactory for the light of Bragge formula and also passes through liquid crystal layer and enter next layer.
Such display pattern is used in United States Patent (USP) US2009033811, and cholesteric liquid crystal is under the sensing of pressure, and state becomes
For plane state, meet Bragge formula, the now the highest referred to as on state of of reflex strength；By applying particular frequencies and waveform electricity
After Chang, cholesteric liquid crystal is changed into Focal conic state by plane state, is unsatisfactory for Bragge formula, and scatter incident light is to reach dark-state.
Above-mentioned display pattern, by incident scattering of light is reached dark-state, causes dark-state to form misty white, therefore display comparison
Spend the highest.
