نحوه ی عملکرد این نوع شیشه به این گونه است. که در حالت عادی شیشه مات به نظر می رسد زیرا ولتاژی به ان اعمال نمی شود و حال زمانی که انرژی ای در حدود تا وات به دو طرف شیشه ی دو جداره اعمال می شود ، ذرات کریستال منظم گردیده و نور را از خود عبور می دهند انگاه شیشه شفاف به نظر می رسد.

The inner layer of smart glass, smart film, consists of several layers of advanced materials that are placed next to each other with high technology, each of which plays a role. The first layers of this smart film are made of PET polymer sheets, which are covered with a very thin layer of a transparent material that conducts electricity. Between two layers of these polymer sheets, a material called PDLC is placed. The constituents of this layer are actually liquid crystals that are completely irregularly distributed in a polymer field, and this irregular distribution causes the light rays to break and make the film opaque.

Smart glass is a new generation of glass made using liquid crystal technology. These glasses change state to opaque or transparent in less than tenths of a second by connecting and disconnecting electricity. Smart glass types can be applied as a label on the glass in the building and there is no need to replace the glass. This glass is used as a board, screen, etc., and they have a great impact on the energy consumption of the environment and creating privacy. These glasses are used in offices, commercial, residential, health and medical facades, hotels, conference halls, partitions, swimming pools, etc.

Older glass was sensitive to moisture, and humidity had a negative effect on its performance. If you intend to use smart glass for humid environments such as bathrooms or swimming pools, the best option for this model would be that humidity does not affect it. Consumers can change the glass from opaque to transparent at any time, or vice versa, which gives the user complete control over the environment.

PDLC and SPD smart glass technology is an active glass technology that switches the situation with electricity. These glasses simply change the amount of light passing through with the help of smart (and generally transparent) materials. By connecting an electric current to the glass, the particles of the material between its layers become regular and transmit light, and as soon as the power is cut off, they return to an irregular state and the glass becomes opaque. These glasses have the ability to control a variety of rays such as visible light, UV, IR, etc.
