Beneficial effect of the present invention: described multi-functional dimming glass is the stray mist attitude under normal conditions, liquid crystal droplet is spherical droplet, liquid crystal molecule does not have consistent the orientation, the optical property of liquid crystal droplet namely is not the isotropy common liq, neither the anisotropy uniaxial crystal, strong light scattering not along rectilinear propagation, again because reflection and refraction take place in the refractive index sudden change, so takes place at liquid crystal and polymer interface place in light beam in liquid crystal droplet.When polymer dispersed liquid crystal layer was applied electric field, liquid crystal molecule roughly was orientated along direction of an electric field in the liquid crystal droplet, so liquid crystal droplet shows as the character of anisotropy uniaxial crystal, and the selective polymer refractive index n
pWith liquid crystal ordinary refraction index n
oEquate when light vertically passes through the Polymer Dispersed Liquid Crystal thin layer, do not have birefringence effect, the light transmission, the visual angle is bad certainly, and birefringence effect has been seen in the side, and film has light mist.When polymer dispersed liquid crystal layer was applied shear stress, the liquid crystal droplet shape became inclination prolate ellipsoid shape from spheroidal, and liquid crystal molecule roughly is orientated along shear direction, and liquid crystal droplet also can be regarded as the anisotropy uniaxial crystal, is n along the shear direction refractive index
eWith refractive index polymer n
pUnequal and differ bigger, the vertical shear direction is refractive index n
