PNLC Smart Film

Structure of electric film

True to the description, Smart Film has a main structure with a film layer consisting of a polymer matrix containing liquid crystals, surrounded by a PET (Polyethylene Terephthalate) film coated with Indium Tin Oxide (ITO), a conductive material. . This creates the product's smart electrical features. An important part of this structure is the conductive copper busbar strip, located along one edge of the membrane. This bar strip is connected to a transformer, which helps control and adjust the state of the smart electric film. When voltage is applied, the liquid crystals in the polymer matrix change arrangement, changing the optical properties of the film from a transparent state to an opaque state or vice versa. The combination of these components creates a flexible and efficient product that allows users to adjust lighting and privacy conveniently and automatically.

Principle of operation

The liquid crystal particles in Smart Film are specifically designed to be effective in blocking or transmitting across a wide range of light wavelength spectrums, from the far infrared to extremely short wavelength ultraviolet rays. This effectively blocks wavelengths that can be harmful to the skin and human body. The transition time between opaque and transparent states is very fast, typically less than 0.5 seconds, which makes Smart Film extremely effective for integration into automation or control systems. When an electric current is applied, the liquid molecules align, creating transparency in the membrane. Conversely, when the power is turned off, the liquid molecules shuffle, causing the glass to fog up and block light from penetrating. This is a flexible and effective mechanism for adjusting lighting and privacy.
