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. It is glued together in a furnace under high temperature and high pressure. In addition to the privacy protection function, smart dimming glass has all the application characteristics of safety glass.

The user can control the transparent and opaque state of the glass by controlling the current on and off. The smart glass itself not only has all the characteristics of safety glass, but also has the privacy protection function of controlling whether the glass is transparent or not. Due to the characteristics of the liquid crystal film interlayer, the PDLC smart dimming glass can also be used as a projection screen instead of ordinary curtains, showing high-definition images on the 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.

There are also adhesive type PDLC smart film which can directly attached to the glass, and then the voltage is applied to make the PDLC film appear transparent and translucent, which realizes people's dual requirements for glass penetration and privacy protection.Even when it is translucent, still some visible light can penetrate, which is impossible for all curtains, and it has an insulating reflection effect on the heat, making the indoor warm in winter and cool in summer, which are environmental protection and energy saving.
