Dimming glass was invented by researchers at Kent State University in the United States in the late 1980s and applied for invention patents. In China, people used to call dimming glass for intelligent electronically controlled dimming glass, smart glass, liquid crystal glass, electronically controlled glass, color changing glass, PDLC glass, Smart glass, magic glass and so on. Intelligent electronically controlled dimming glass began to enter the domestic market in 2003. Due to the high price and few people, the development in China has been slow in the past decade. In recent years, with the sustained rapid growth of the national economy, the domestic building materials market has developed rapidly. Due to the significant cost reduction, the intelligent electronically controlled dimming glass has gradually been accepted by the construction and design industry and has begun to be applied on a large scale. The downward adjustment of the market price, dimming glass has also begun to enter the field of home decoration applications, I believe that in the near future, this practical high-tech products will enter thousands of households.
