Switchable smart film for glass
A film applied to ordinary glass. Press a button and the glass is clear; press again and it turns matte, like a drawn curtain.
It is a thin film with a liquid-crystal layer. It is applied to the glass and connected to power: without power the glass is matte, with power it is clear. No curtains or blinds needed. It is also called smart glass, switchable glass, privacy glass or PDLC film.
The film is matte. Light comes through, the view does not.
At the press of a button the whole glass turns clear at once.
Self-adhesive film is installed on the glass you already have.
Anywhere glass has to be both open and closed.
