Smart glass film is one of the latest technological breakthroughs, enabling glass to be instantly transformed from a clear state to an opaque state, by the flicking of a switch, providing immediate privacy and security, when required. Smart Transparent Film (STF) is also known as PDLC film (Polymer Dispersed Liquid Crystal), electrically controlled smart film, electronic curtain, etc. This kind of product is based on membrane technology, which attaches mixed claviform macromolecule liquid crystal and prepolymer to a transparent conductive substrate, bringing in current through the electrode at the edge of the substrate. The latest generation of smart film provides a simple, affordable alternative to other, intelligent glass solutions.

Smart Glass Film Principle:
When the power is switched off, the liquid crystal molecules are randomly oriented, scattering light, and the switchable smart film becomes opaque (frosted, private).
When the small electrical supply is switched on, the liquid crystal molecules align, incident light passes through, and the switchable smart film instantly clears (is transparent). When the power is switched off, the liquid crystal molecules are randomly oriented, scattering light, and the switchable smart film becomes opaque (frosted, private).

PDLC Smart Glass Products Feature：
(1) Privacy Protection:
transparent (power on), opaque but light pervious (power off) at high switching speed. It’s instantaneous to make the film go from completely transparent to fully opaque or vice versa.

(2) Energy Saving:
In an energized state, only 5W of low power consumption per square meter per hour is required. 60% of infrared can be shielded by the smart film to reduce heat radiation and transfer; 99% of UV can be shielded to protect interior furnishings from color fading or aging and to protect personnel from diseases caused by ultraviolet radiation.

(3) Sound Proofing:
A smart film having a sound-damping effect; can effectively block all kinds of noise.

(4) Diversified Control:
Smart glass is versatile and can be controlled in many ways, like a wall switch, dimmer, motion detector, light, temperature sensor, remote, or remote network control.

(5) With a simple structure, low cost, easy installation, and easy controlling mode, there is no need for complicated installation of curtains and subsequent clean-up.

(6) It can be equipped with any size of transparent glasses when powered on, and opaque ones when powered off. It’s free to switch, simple, and convenient.
