Principle and structure: Product principle, the principle of structured products shown: ⑴ when dimming glass is powered off, the glass in the middle of the polymer liquid crystal material disordered arrangement, so that light can not penetrate the glass, this time to see results milky white opaque state. ⑵ when dimming glass energized, in the electric field, the glass in the middle of the polymer liquid crystal material ordered, so that the light can be through the glass, this time to see the effect of that is transparent and colorless glass state. Product schematics electric adjustable film is using a special process, the liquid crystal film between two glass cured. Dimming principle dimming glass is: in a natural state (power is not applied electric field), which are arranged inside the liquid crystal is random, the liquid crystal refractive index lower than the outside of the polymer, the scattering of the incident light occurs in the polymer , milky white, ie opaque. The equivalent of two conductive films of liquid crystals two planar electrodes. When the electric field is applied (power) later, there is a polymer dispersed liquid crystal droplets are rearranged, the liquid crystal changes from a disordered array directional ordered arrangement, the refractive index of the liquid crystal is equal to the refractive index of the polymer, the incident light is completely can form a transparent state. Technical parameters V.
