1. PDLC Smart Film Introduction
Switchable Transparent Film (STF) is known as
PDLC film (Polymer Dispersed Liquid Crystal), also
called electric smart film, electronic curtain, etc. It
is a new electronic controlled optical product,
based on membrane technology, attach mixed
claviform macromolecule liquid crystal and
prepolymer to transparent conductive substrate,
to let transparent conductive substrate possesses
nature of liquid, crystal and photoelectricity.
The latest generation of smart film provides a
simple, affordable alternative to other 'intelligent
glass' solutions.
1.1. Smart Film Structure and Working Principle
Smart Film Working Principle:

When power off, the liquid crystal molecules are randomly oriented, scattering light
and the Smart Film becomes opaque (frosted, private).
When power on, the liquid crystal molecules align and incident light passes through,
the Smart Film instantly becomes clear (transparent).
1.2. PDLC Smart Products Feature
(1). Privacy Protection:
Transparent (Power on), Opaque but light pervious (Powder off) in high switching
speed.
(2). Energy Saving:
In an energized state, only 5W low power consumption per square meter per
hour. 60% infrared can be shield by smart film to reduce heat radiation and transfer;
99% of UV can be shield to protect interior furnishings from color-fading or aging, to
protect personnel from diseases caused by ultraviolet radiation.
(3). Sound Proofing:
Smart film is with sound damping effect, can effectively block all kinds of noise.
(4). Diversified Control:
Smart film and smart glass can be controlled by wall switch, dimmer, motion
detector, light, temperature sensor, remote controller or remote network control.
(5). With simple structure, low cost, easy installation, and easy controlling mode,
there is no need for complicated installation of curtains and following clean-up work.
(6). It can be equipped with any size glasses, transparent when power on, opaque
when power off. It’s free to switch, simple and convenient.
1.3. PDLC Smart Products Categories
(1). Self-Adhesive PDLC Smart Film
Self-adhesive smart film has a special glue layer on one side of the film, which can be
pasted on existing glass directly, transparent when power on, opaque/frosted when
power off, will give you transparency and privacy when need, and enlarge the space.
It's suitable for existing window or door glasses or existing interior partition glasses,

also can be applied to produce insulating smart glass.
Compared with traditional laminated smart glass, SA-STF is light, easy to deliver and
convenient for installation. It is a time saving option to paste on glass surface and
offers best solution for the already installed ordinary glass to realize projection,
advertisement, exhibition display.
(Self-adhesive smart film is called SA-STF for short hereinafter)

(2). Non-Adhesive Smart Film
Non-adhesive smart film is the very regular smart film in market, which is used for
making smart glass, it should be mounted into 2 pieces of glasses with EVA by
laminating machine and it’s used for glass factory to process to make smart glass.

2. PDLC Smart Glass
Smart glass is one kind hi-tech laminated glass based on PDLC technology, also
known as intelligent glass, LC dimmable glass. Sandwich the PDLC film between two
panels of glasses, a new optoelectronic product comes out after high temperature
and high pressure agglutination. As the PDLC film is opaque when powder off,
transparent when powder on, the smart glass can not only be normal glass, but also
plays as electrically controlled curtain to protect privacy and provide you
comfortable & green life.

3. Iwitte PDLC Smart Film for Rear Projection System
Rear Projection System Components and Principles:
1). Device Components: Controlling device, projector and smart film /smart
glass.
2). Projection Principles: the controlling device consists of output controller,
power controller and process unit. Connect projector with output controller, smart
film / smart glass links with power controller, then output controller and power
controller connect with each other within controlling device set by process unit.
When power on, smart film / smart glass becomes transparent, can plays as clear
common glass; when power off, smart film / smart glass becomes opaque, it canbe
used as rear projection screen.
Wide-angle precision optical projector is recommended, which is 0.233m
ultra-short focal distance. 200 inch projection image is easy to achieve when 4500lm
projector applied; for 6000lm brightness, larger than 200 inches projection image is
enabled like showcase advertising, big new products release conference, cultural
transmission company, concerts, exhibitions and other commercial advertising.
