Note: Tpye of glass: super wihte, white, fireproof, Low-E coated glass etc.
(1) Opaque statue of STG
STG is composed of two transparent ITO film sandwiched between a layer of plastic and liquid crystal. The plastic and liquid crystal include a liquid crystal ball and a polymer, and the liquid molecule director is approximately parallel to the glass substrate , the polymer is surrounded by the liquid crystal micro droplet, the refractive index of the polymer is np , which is similar to the refractive index of the glass. Approximately 1.5 , an is isotropic substance, the unusual refractive index and the ordinary refractive index of liquid crystals are ne and n, respectively. When the vertically incident visible light passes through the glass and transparent ITO film ,it enters the liquid crystal sphere and the polymer interface, due to neis not equal to ne , So scattering occurs and the STG is atomized.
(2) Transparent STG
When the external electric field is applied, the electric field is formed between the two transparent ITO films, and the liquid crystal molecules are arranged in the direction of the electric field. When the vertically incident visible light passes through the glass and the transparent ITO film, it is incident to the interface between the liquid crystal sphere and the polymer. Because the no direction is perpendicular to the direction of light propagation and no is equal to np, the glass is transparent.
(3) STG haze
The main indicator of the advantages and disadvantages of STG glass optical performance is transparency. In fact, it is the haze. The smaller thaze when energized, the better haze when the power is cut off. When the external electric field is applied, the light is perpendicular to the direction of the transparent conductive film. When incident, although nLC is approximately equal to no, However, due to the difference between the nP and no values, scattering still occurs at the interface between liquid crystal droplets and polymers. This is the main reason for the haze.
(4) View angle
When the ITO film is power on, Angle between incident light and the vertical direction of the electric control film is not zero(Called the view angle “a”) The direction of light propagation in the STF is not parallel to the liquid crystal molecule pointing vector, as shown in the figure:At the interface between liquid crystal droplets and polymers, the component of light vibrating along the NE direction is scattered, and the larger a is, the more scattered, so the mist increases with the increase of the angle of view, which is the characteristic of the photoelectric effect of liquid crystal.
