Dimming glass is a new type of special photoelectric glass product with a sandwich structure in which a liquid crystal film is compounded between two layers of glass and bonded together by high temperature and high pressure. The user controls the transparent and opaque state of the glass by controlling whether the current is on or off. The glass itself not only has all the characteristics of safety glass, but also has the privacy protection function of controlling 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, replacing the ordinary screen, presenting high-definition pictures on the glass image.

 Intelligent electronically controlled dimming glass began to enter the domestic market in 2003. Due to the high price and few people who know it, the development in China has been slow in the next decade. With the sustained and rapid growth of the national economy and the rapid development of the domestic building materials market, smart electronically controlled dimming glass has gradually been accepted by the construction and design industries and began to be applied on a large scale due to the cost reduction. With the further reduction in cost and the market price With the downward adjustment, dimming glass has also begun to enter the field of home decoration applications. I believe that in the near future, this practical high-tech product will enter thousands of households.
