About Us
Polymer Dispersed Liquid Crystal (PDLC) films represent a remarkable advancement in the field of materials science, specifically in the areas of smart glass and electro-optical applications. These films are designed to control the transparency of a surface, making them highly desirable in various industries, including architecture, automotive, electronics, and privacy-related applications.

PDLC films are a type of smart film composed of liquid crystal droplets dispersed in a polymer matrix. The liquid crystals are responsible for the film’s ability to alter its transparency when an electric field is applied.
Liquid Crystals
These are the central materials that give PDLC films their switchable properties. Liquid crystals are unique in that they exhibit properties of both liquids and solids.
Polymer Matrix
The polymer serves as the base material in which the liquid crystals are dispersed. It provides structural support and defines the mechanical properties of the film.
Electrodes
Thin transparent electrodes, typically made of indium tin oxide (ITO), are applied to both sides of the film.

Our History
Our History
The working mechanism of PDLC films is based on the electro-optical effect of liquid crystals. The film’s optical properties change depending on the alignment of the liquid crystal molecules

Opaque State
Opaque State
In the absence of an applied voltage, the liquid crystals within the film are randomly oriented. This random arrangement causes the light to scatter in different directions,

Transparent State
Transparent State
When a voltage is applied to the PDLC film, the liquid crystal molecules align along the direction of the electric field. This alignment allows light to pass through the film with minimal scattering

Automotive Applications
PDLC films are also employed in the automotive industry to enhance privacy, comfort, and energy efficiency. For example, automotive glass can be made using PDLC technology to create windows that can switch between transparent and opaque states, offering privacy to passengers while reducing heat buildup within the vehicle.

Our Home
PDLC films contribute to energy efficiency by reducing the need for air conditioning and heating. When applied to windows or building facades, they can block unwanted heat or UV rays, improving thermal insulation and reducing the reliance on artificial climate control.
This has a significant impact on reducing energy consumption in both residential and commercial buildings. By adjusting the opacity of the glass, users can regulate the amount of heat and light entering a space, optimizing indoor comfort without sacrificing energy efficiency.
Advantages of PDLC Films
PDLC films are increasingly being used in modern architectural and interior design projects.
PDLC films allow users to switch between transparent and opaque states with ease, offering instant privacy without the need for curtains or blinds.
