Dimming glass is a new type of special optoelectronic glass product which combines liquid crystal film into two layers of glass and is laminated by high temperature and high pressure. The user controls the transparent and opaque state of the glass by controlling the on and off of the current. The glass itself not only has the characteristics of all safety glass, but also has the privacy protection function to control the transparency of the glass. Due to the characteristics of the liquid crystal film interlayer, the dimming glass can also be used as a projection screen instead of the ordinary screen to present a high-definition picture on the glass. image.
