Product Description

PDLC Film Self Adhesive Switchable Smart Window Tint Film in Roll

PDLC smart Film

(1) Structure diagram:

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 PDLC film+0.76mm(EVA)+ Glass thickness(Glass 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.

Technical parameterAPPLICATION:

Large command and control dispatch center office, meeting room, negotiation room, special hospital room. Operating room, villa toilet. Shower room, window of entertainment room. Isolation. screen, etc..

Courts. Prisons. Jewelry shops. Museums. Bank Windows. Curtain walls. Counter. Isolation, etc.. Large special screen projection screen, etc..

Function:

a) Environmential protection, saving-energy,safety,heat presevation,anti-condensation

b)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 radiation

C) The suitable visible light penetration rate has a certain degree of concealment for outdoor bright light

d) Low solar coverage effectively prevents solar thermal radiation from entering the room

e)High infrared reflectivity, limiting outdoor secondary thermal radiation into the room

f) 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 saving

g) 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 energized, opaque when the power is cut off, light is still abundant under the protection of privacy, and the reception room in the hidden office area is still bright, not only comfortable, but also saving lighting.

Transparency in power, opacity, opacity: fast response, instant privacy within 1/10 seconds

i) Sound insulation features excellent reflection, heat absorption type hollow glass, the middle electric control film and film have sound damping effect, can effectively block all kinds of noise up to 38 decibels, plus hollow, sound insulation effect is even better

j) Projection characteristics: Under the closed state, visible light scattering reaches more than 43 %, and the penetration rate reaches more than 50 %. It can be used as a projection screen in a street mall, playing a good advertising effect. If the projection is in the open state, there is also a three-dimensional ethereal effect

k) Control diversity: hand control, remote control, optical control, audio control, infrared, remote network control

FAQ

1. How does Smart Film work?

In "Off State" when no electrical power is applied on the smart film the light is absorbed or scattered and the film looks dark gray or white. In "On State" the light is transmitted and the film looks transparent.And we can provide the video of installation!

2. What is the product lead time?

Lead time for PDLC Film Products is 7 days after received payment.
