basic principles of using eva dimming film

basic principles of using eva dimming film:

1. when the dimming film is powered off, the polymer liquid crystal materials in it are arranged in disorder, making it impossible for light to penetrate the film. the effect seen at this time is a milky white opaque state.

2. when the dimming film is energized, the polymer liquid crystal material in the middle of the film is arranged in an orderly manner under the action of the electric field, allowing light to pass through the film. the effect seen at this time is a transparent and colorless film state.

eva dimming film is a film that can adjust the state of light passing through. it mainly works between the scattering state and the transparent state. that is to say, the film itself can change between transparent and non-transparent states (the visual effect is close to frosted glass), and the transparency is adjusted by voltage.
