In recent years, smart dimming glass has been widely used in home partitions, hotel bathroom partitions, office partitions and other scenarios. The glass itself has all the characteristics of safety glass, but also has the control of glass transparent or not privacy protection function. EC dimming glass has a slow response speed, which may be as long as several minutes. PDLC has very limited thermal insulation effect. Increasing the thermal insulation effect can add a layer of low-E glass, while SPD and EC technologies have good thermal insulation effect.Due to the relatively high operating voltage, the application scenarios are relatively limited due to the consideration of security risks, and are relatively rare in China. PDLC has two basic states: transparent and atomized. Even if glass atomized, a lot of light will pass through, that is, transparent but opaque. PDLC can also create transformable transparent or atomized graphic effects on glass, with good design and expansion properties. EC and SPD can continuously adjust the rate of light passing between transparent and colored states, but cannot design graphic effects.
