Product Description

Smart dimming glass is a layer of liquid crystal film (commonly known as dimming film, LCD or PDLC film) sandwiched between two layers of glass.

When the PDLC smart dimming glass is turned off, the liquid crystal molecules inside the electronically controlled smart glass will show an irregular dispersion state, and the electronically controlled glass will appear transparent and opaque; when the smart glass is energized, the liquid crystal inside The molecules are neatly arranged, and the light can penetrate freely. At this time, the smart glass is instantly transparent.
