Laminated smart film represents a breakthrough in glass enhancement, using advanced PDLC technology to deliver instant privacy and clarity. This smart film consists of several layers that work together to create a dynamic, switchable surface. The core of the smart film uses PDLC, which stands for Polymer Dispersed Liquid Crystal. PDLC contains liquid crystal droplets suspended in a polymer matrix. These droplets respond to electrical signals, changing the film’s appearance from transparent to frosted in milliseconds.
Manufacturers build laminated smart film by sandwiching the PDLC layer between two sheets of Indium Tin Oxide (ITO) film. ITO film conducts electricity, allowing the PDLC to react quickly and evenly. Protective PET films cover the outer surfaces, shielding the smart film from scratches and environmental damage. This multi-layer structure ensures high clarity, low haze, and long-lasting performance.
The following table outlines the main components and their functions:
Component/Material | Description |
Protective Film | Two outer layers of PET film to protect the smart film from scratches. |
ITO Film | A two-layer Indium Tin Oxide film that allows electrical current to pass through the PDLC material. |
PDLC Core | Composed of liquid crystal droplets suspended in polymer, coated in ITO film for conductivity. |
PDLC technology gives laminated smart film its unique ability to switch between privacy and transparency. When users apply an electric current, the liquid crystals align, making the glass clear. When the current stops, the crystals scatter light, turning the glass frosted. This process happens almost instantly, providing flexible control over light and privacy.
Laminated smart film supports wide-width customization, making it suitable for large windows, partitions, and facades. The seamless design and high optical quality set it apart from other glass solutions.

Laminated smart film uses advanced technology to control light and privacy. The core of this smart film is PDLC, which stands for Polymer Dispersed Liquid Crystal. This material contains tiny liquid crystal molecules that change their orientation when electricity passes through them. The structure of smart film includes several layers, each with a specific function.
Structure Component | Function Description |
Glass | Acts as the outer layer providing structural integrity. |
EVA | Serves as an adhesive layer that bonds the PDLC film to the glass. |
PDLC Film | Contains liquid crystal molecules that control light transmission based on electrical activation. |
EVA | Another adhesive layer ensures the PDLC film is securely laminated. |
Glass | The final layer that completes the laminated structure, allowing for aesthetic and functional properties. |
The ITO layer, which stands for Indium Tin Oxide, conducts electricity across the smart film. This layer is essential because it allows the liquid crystals to respond quickly and evenly. When powered on, the liquid crystal molecules align, and the smart film becomes clear, letting up to 91% of light pass through. When powered off, the molecules scatter light, making the film opaque and providing privacy with a haze level above 90%. This unique structure makes switchable pdlc film a popular choice for modern buildings and vehicles.
The switching mechanism of smart film relies on the behavior of liquid crystals inside the PDLC layer. In their natural state, these crystals are randomly oriented. This random arrangement scatters light, so the smart film appears frosted or opaque. This state ensures privacy and blocks the view from both sides.
When an electric voltage is applied, the ITO layer conducts electricity, causing the liquid crystals to align in a uniform direction. This alignment allows light to pass through, making the smart film transparent. The transition between these two states happens almost instantly. The response time for switching from ON to OFF is about 100 milliseconds, while switching from OFF to ON takes only about 10 milliseconds.
Transition | Time |
ON → OFF | ~ 100 ms |
OFF → ON | ~ 10 ms |
This rapid switching gives users precise control over privacy and light. Smart film can switch between clear and frosted modes as often as needed without losing performance. The film also maintains high clarity and low haze in transparent mode, which is important for spaces that require both visibility and privacy.
●In the transparent state, smart film allows natural light to fill the room.
●In the opaque state, it provides privacy and reduces glare.
This flexibility makes smart film ideal for offices, homes, hospitals, and transportation.
