Smart glass’s structure is: tempered glass+EVA+non-adhesive smart film+EVA+tempered glass.
The smart film is also called PDLC film. PDLC has properties to become transparent when electric current is supplied to it, allowing you to turn the film from transparent to opaque with simple controls.
Here is the working schematic diagram of PDLC between glass:
A simple ON – OFF mode switches the film from being clear (transparent) to frosted (opaque). In its frosted state the film acts as an electronic blind providing privacy and security for any glass, window or partition.
Switchable smart glass is available in size up to 1800mm *3660mm and can be cut to any size. Multiple pieces can be joined together to create large switchable glazed panels or partitions.
