[0018] The working principle of electrically controlled fogging glass, also known as electro-induced liquid crystal fogging glass (STG for short), is based on the characteristics of liquid crystal polymers. This glass achieves dimming function through a dimming film (STF for short) sandwiched between two pieces of glass. The dimming film is composed of two transparent conductive films and a plastic-liquid crystal core layer. 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 arranged along the direction of the electric field. In the power-on state, the liquid crystal molecules are arranged in order, so that the refractive index of the liquid crystal matches the refractive index of the polymer, and light can pass through unimpeded, and the glass appears transparent. In the power-off state, the liquid crystal molecules are arranged in disorder, causing the light to scatter in the polymer layer, making the glass appear foggy and opaque.

[0019] The emergence of electrically controlled atomized glass and its driving circuit is a major innovation in traditional glass technology.
