HOMEWELL Switchable Transparent Glass ,
refered to as STG, this product is made by the dry process of
gluing glass, and the switchable transparent film(STF) is glued
between two pieces of glass. The glass meets the national
standard for laminated standard.(2) Exterior structurel
dimensions: Glass thickness +0.76mm(EVA)+0.44mm

thickness:3mm-20mm) 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 ne is 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.Raw MaterialGlass: Car

saving-energy,safety,heat presevation,anti-condensationb)High UV
resistance function, It can block more than 99 % of ultraviolet
light. While it does not lose visible light into the room, it
isolates a large amount of ultraviolet light to prevent the fading
and aging of interior decorations and furniture. It can also
protect people from diseases caused by excessive ultraviolet
radiationC) The suitable visible light penetration rate has a
certain degree of concealment for outdoor bright lightd) Low solar
coverage effectively prevents solar thermal radiation from entering
the roome)High infrared reflectivity, limiting outdoor secondary
thermal radiation into the roomf) The extremely high absorption of
more solar radiation heat and ultraviolet rays to reduce the
transmission of infrared and ultraviolet light, reduce the energy
consumption of indoor air-conditioning, heat insulation and energy
savingg) A high degree of safety, when damaged by external forces,
will only cause cracks, but will not break down, there is no danger
of splashing glass fragments.h) The privacy protection is
transparent when
