With the development of science and technology and the improvement of people's living standards, ordinary car window films have become more and more difficult to meet the consumer needs of car owners, and people's demand for intelligent and high-tech window film products is becoming more and more urgent.


Longsheng PDLC film endows dust-covered windows with intelligent life for nearly 130 years, making our daily lives more comfortable and safer, and opening a new chapter in the electronic intelligent window industry!


1. The working principle of Longsheng dimming film


Light-adjusting film (PDLC, Polymer Dispersed Liquid Crystal), literally translated as polymer dispersed liquid crystal. As the name implies, the light-adjusting film is a film that can adjust the light passing state. It mainly works between the scattering state and the transparent state, that is, the film itself can be changed between the transparent and opaque state (the visual effect is close to frosted glass), and the transparency is adjusted by the voltage.


When energized: The polymer liquid crystal material in the middle of the light-adjusting film is arranged in an orderly manner under the action of an electric field, so that light can pass through the film to achieve a transparent film state.


When the power is off: the polymer liquid crystal materials are arranged disorderly, so that the light cannot penetrate the dimming film, and the effect seen at this time is an opaque state.

4. Other application fields of Longsheng PDLC film


The dimming film can be directly attached to the transparent strengthened glass, which is transparent when energized; it is foggy when not energized, and has a wide range of applications.


1. Business applications

Example 1: Application of projection screen.

Example 2: Office area, conference room, monitoring room partition application.


2. Residential applications

Example 1: External setting, adding dimming glass to the balcony bay window.

Example 2: The indoor space is divided, and the room is separated by dimming glass to improve the spatial layout.

Example 3: Used as a small home theater screen, effectively combining the screen and screen.

Example 4. Under the premise of selecting safe voltage, using dimming glass as bathroom and sanitary partition, not only makes the layout bright and bright, but also protects privacy.


3. Application in medical institutions

It can replace curtains and play the function of partition and privacy protection. It is solid and safe, soundproof and eliminates impurities, and has the advantages of environmental protection, cleaning and non-polluting. It removes worries and psychological pressure for medical workers and patients.


4. Anti-theft applications in museums, exhibition halls, shopping malls, and banks

Maintain a transparent state during normal business applications. In case of emergencies, remote control can be used to instantly reach a fuzzy state, so that criminals lose their targets, and the personal and property safety can be guaranteed to the greatest extent.

In short, with the continuous maturity of smart dimming film technology, the entire dimming film industry may be overturned by the popularization of smart dimming glass in the future.
