The self-adhesive dimming film is composed of a protective film on the surface, an ITO film, and a liquid crystal polymer. Self-adhesive dimming film has similar performance function as smart dimming glass. It can control the conversion between transparent and opaque glass by adjusting the power supply voltage. The power-on state is transparent and the power is opaque. It provides a good solution for some projects that have been installed with ordinary glass or need to be projected on ordinary glass. It is not necessary to replace the entire glass installation and can be directly attached to the surface of the cleaning glass.
