We offer 2 kinds of Smart PDLC Film:
1. Self-adhesive Smart PDLC FILM
2. Non-adhesive Common Smart PDLC FILM
NOTE: size: max 1.5m (widh) *3m (length)for one piece for one roll
we have 1.2m *30m or 1.4m*30m or 1.5m * 30m for Self-adhesive Smart PDLC FILM, and 1.2m *30m or 1.4m*30m or 1.8m*30m forNon-adhesive Common Smart PDLC FILM .
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
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.
SmartLC Film(Liquid Crystal Film) consists of two PET films and one
PDLClayer. While voltage is brought to the two PET films, the smart
LC filmwill turn from opaque state to transparent.
Theworking principle of smart LC film is illustrated in below. With
thefilm is "off", the disordered orientation arrangement of
liquidcrystals leads to the mismatch of micro refractive index
andcause strong light scattering(during which the appearance of
asmart film is opaque and in ivory white); while proper voltage
isadded to the film, the electric field makes the liquid
crystalarrange in order. The micro refractive index in a
compositematerial is widely distributed. Light scattering is
restrained(during which the film is in transparent state).
Smart LCfilm consist of two layers of ITO film sandwiched with
PDLClayer. Through the applied power control, the smart LCfilm
canquick change in astate between clear and opaque.
The pictures above are principle drawing of smart LC film. When the
power of smart LC film isturned off ( "OFF"state),theliquidcrystal
turn into scattering position and themicro reflective index of
material is mismatch, resulting in the strong scattering effect;
the smart LC film is opaque. When the power is applied to the film,
crystal lines up and the reflective index tend to same, then the
scattering is sharply depressed,for this time the film turn opaque
Smart film A4 SIZE SAMPLE IMAGE:
Theappearance of Smart LC Film must reach uniform color, haze and
lighttransmittance. Two ITO film layer should splice strongly
withoutstripping; no crease, black spot or slippage on the surface
of film; novisible impurity, not removed visible adhesive, Foreign
matters,eutectic spots, scratch, etc. Accumulated allowance should
meetrequirements showed in the table below.
Intensiveexistenceappear 4 or more than 4 defects, and their
spacingis less than 200mm, which is regarded as Intensive
Whentesting, the light intensity of the front and back side of
smart LCfilm should keep between 300 and 500lux; the distance from
smart LCfilm to the inspector's eyes should more than 1m, line
ofsight perpendicular to the surface of the smart LC film.
Theworking voltage of DEFI Smart LC Film is 70V(50Hz). The film
becometransparent by applying power (ON state) and opaque (matte
effect)when power off (OFF state). Detailed specification showed in
Features of DEFI Smart LC Film
DEFISmart LC Film adopt unique liquid crystal formula, make thenew
liquid crystal materials dhesive on the high quality
flexibleconductive film-ITO film. Excellent optical performance,
Highon&off contrast, Low power consumption and widely
application. Advantages of DEFI Smart LC filmas 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 over76%. The film is with outst
