Principle of smart switchable glass

The smart film is composed of a plastic-liquid crystal core layer sandwiched between two transparent conductive films.
The plastic-liquid crystal core layer includes a liquid crystal ball and a polymer.

The director of the liquid crystal molecules is approximately parallel to the glass substrate, and the polymer surrounds the liquid crystal micro Drop around.

When an external electric field is applied, an electric field is formed between the two transparent conductive films, and the directors of the liquid crystal molecules are aligned along the direction of the electric field, and the visible light that is incident perpendicularly can pass through the glass.
