We call Smart Film PDLC Film as Smart Glass Film, Switchable Smart Film, Privacy Glass Film, PDLC Film , Magic Glass Film , Electronic Film, Switchable Transparent Film etc ...
We offer 2 kinds of Smart PDLC Film:
1. Self-adhesive Smart
2. Non-adhesive Common Smart
Self-adhesive smart film:
1. install on the surface of existing glass
2. size: max 1.2m (widh) *4m (length)
3. color: white/gray (gray color price is higher, if you want gray color please contact us to change price for this link)
Common smart film:
1. Mounted into 2 pieces of glass to make smart glass
2. Size: max: width is 1.2m, length is no limited, you can even ask for 1000m
3. Color: white/gray (gray color price is higher, if you want gray color please contact us to change price for this link)
1. Switch on, transparent; switch off, opaque, which achieves the double requirements of daylighting and privacy.
2. Safety: the fragments will be stick on the film when the glass is crushed. That glass fragments hurt people will never happen
3. Environmental protection: above 90% infrared and 98% UV can be shielded.
4. Anti-aging, anti-fade.
5. Sound insulation: 2 to 3 time of ordinary glass
6. when off state, can as rear projection film to use.
Smart film A4 SIZE SAMPLE IMAGE:
Smart LC Film(Liquid Crystal Film) consists of two PET films and one PDLC layer. While voltage is brought to the two PET films, the smart LC film will turn from opaque state to transparent.
The working principle of smart LC film is illustrated in below. With the film is "off", the disordered orientation arrangement of liquid crystals leads to the mismatch of micro refractive index and cause strong light scattering(during which the appearance of a smart film is opaque and in ivory white); while proper voltage is added to the film, the electric field makes the liquid crystal arrange in order. The micro refractive index in a composite material is widely distributed. Light scattering is hightly
restrained(during which the film is in transparent state).
Smart LC film consist of two layers of ITO film sandwiched with PDLC layer. Through the applied power control, the smart LC film can quick change in a state between clear and opaque.
The pictures above are principle drawing of smart LC film. When the power of smart LC film is turned off ( "OFF" state), the liquid crystal turn into scattering position and the micro reflective index of material is mismatch, resulting in the strong scattering effect; this moment
the smart LC film is opaque. When the power is applied to the film, the liquid
crystal lines up and the reflective index tend to same, then the scattering is sharply depressed, for this time the film turn opaque to clear.
Apparent Quality:
The appearance of Smart LC Film must reach uniform color, haze and light transmittance. Two ITO film layer should splice strongly without stripping; no crease, black spot or slippage on the surface of film; no visible impurity, not removed visible adhesive, Foreign matters, eutectic spots, scratch, etc. Accumulated allowance should meet requirements showed in the table below.
Remark:
Intensive existence: appear 4 or more than 4 defects, and their spacing is less than 200mm, which is regarded as Intensive existence.
When testing, the light intensity of the front and back side of smart LC film should keep between 300 and 500lux; the distance from smart LC film to the inspector\'s eyes should more than 1m, line of sight perpendicular to the surface of the smart LC film.
Optical Performance
The working voltage of DEFI Smart LC Film is 70V(50Hz). The film become transparent by applying power (ON state) and opaque (matte effect) when power off (OFF state). Detailed specification showed in the table below.
Weather-proof Performance:
Features of DEFI Smart LC Film
DEFI Smart LC Film adopt unique liquid crystal formula, make the new liquid crystal materials dhesive on the high quality flexible conductive film-ITO film. Excellent optical performance, High on&off contrast, Low power consumption and widely application. Advantages of DEFI Smart LC film as below:
1. Excellent optical Performace
When the smart film is in "off" state, the haze is over 90% while in on state, the ransmittance is over 76%. The film is with outstanding optical performance.
2. Great Stability
The film can keep its excellence optical performance after switching for over 80 million times.
3. Larger Size Production Capacity
The maximum width of the smart film is 1.2m, the length is unlimited. Customized service is available.
4. Widely Application
DEFI smart film is flexible materials with high elastic deformation, which can be used directly on the surface of ordinary glass and curved glass. It can be made into Smart LC Glass by laminated encapsulation.
Technical Advantages
DEFI independently developed a set of high precision automatic production equipment for Smart LC Film. The advanced roll-to-roll processing technique allows the large-scale continuous production of Smart LC Film to reach 1,250mm.
The film is made of unique liquid crystal composite materials, together with optical-grade flexible conductive thin film with high-quality ITO coating. Finished film have excellent optical performance, thermal and mechanical performances as well as great weather resistance.
We have a group of well-educated and experienced specialists who devote themselves to the technology of smart film. For this project, an institute of Functional Thin Film Materials was established, which provides a strong foundation for improving the product performance and new product development.
How it work
As the figure show below, the Smart Glass adopt a manufacturing technology like laminated glass, which use Smart LC Film (hereinafter referred to as Smart Film) as a mid-layer. Through high-temperature high press processing, the Smart Glass have been made and the feature that transparent when power on and opaque when power off.
Technical Features
When power on, the film become transparent; when power off, it becomes opaque; Quick change; Multiple control way: switcher, sound-controlled, light-controlled, temperature-controlled, remote-controlled, remote network-controlled, etc. Custom services are available.
Sound insulation, heat insulation and preservation; Environment-friendly; The smart glass can adjust automatically its light transmittance by adjusting voltage according to the change of the temperature and light outside the window.

Package & Marking
1. Optical Performance
The smart film will be laminated by double-sides protective film when packing and shippment. Before using the film, clients have to tear off the protective film.
2. Packing
According to client\'s requirements, the smart film will be packed by Cases Type or Rolls Type. Cases Type means that the smart film will be packed into a big wooden case, each slice will be separated by plain paper, together with foam rubber sponge around as buttering. Rolls Type means that the smart film will be rolled by a 12 inches paper tube, together with carton outside.
3. Sign
The product labels will be sticked outside the cartons or wooden cases for signing the product name, models, batch number, quantity and date, etc.
