product description

Meidun Invisible Vision Glass is an electronically controlled light-transmitting glass designed using the optical principle of polymer liquid crystal, which can be switched between transparent and opaque at will.

The polymer medium and the liquid crystal dispersed coexist in the Meidun Vision glass. Under normal conditions, the refractive index of the polymer medium and the extraordinary refractive index of the liquid crystal are different (Np≠No), resulting in light scattering in the medium, so that the glass is opaque. Milky state. After electrification, the micro-electric field within the glass causes the liquid crystals to rearrange in the polymer medium. After the rearrangement, the extraordinary refractive index of the liquid crystal is the same as the refractive index of the polymer medium (Np=No), so that the glass becomes a uniform medium, and the light is no longer scattered, so that the glass is in a transparent state.
