Dimming Glass for Auto

Principle of dimming glass: Usually(power off), the internal liquid crystal arranges irregularly and its index of refraction is smaller than the external polymeric substance's, so the incident light scatters on the polymeric substance which makes the glass become milk white, not transparent. While when the dimming glass is electrified, the internal solution in polymeric substance which contains the diffused liquid crystal will rearrange, therefore the liquid crystal will order regularly. In this occasion, the refractive index of the liquid crystal and polymeric substance will be equal, thus the incident light can come through the dimming glass completely which makes it become transparent.
The dimming glass is mainly utilized in privacy and secret protection places. And window glass made of these dimming glasses for automobile, locomotive, and military vehicle is just like electromagnetic control curtain, when privacy is needed you can electrify the glass to make it opaque. While when light and perspective are needed you can power off the glass so the glass will be transparent again.
The dimming glass of automobile, locomotive and military vehicle is opaque when it is parking. Therefore, even though the door is opened by the thief he/she still cannot steal the car, because he/she cannot see the road. In this occasion, the dimming glass plays an anti-theft role.
