What is smart glass?

Smart glass is also known as tinted glass, smart tint, switchable glass, privacy glass, electromagnetic glass, SPD glass, magic glass and various other names.

Generally speaking, all these names are related to PDLCs (polymer dispersed liquid crystals) technology, such as SPD and various electromagnetic technologies for the same purposes that have been used very rarely.

How Smart Glass Works There are polymer dispersed liquid crystals sandwiched between two transparent films. In a normal state without power, the liquid crystals are arranged randomly and scatter the incoming light. When voltage is applied to the two transparent films, the polymer dispersed liquid crystals are aligned along the electromagnetic field and allow light to pass through with low dispersion. To see the transparency of the smart film.

The distinctive feature of smart glass is that in a normal state without voltage, it does not block light but only scatters itself like swollen or etched glass sand. The total thickness of the smart film is only 0.5 mm, and the switching time is less than 0.5 seconds. By adjusting the voltage, we can adjust the transparency of the glass called dimmable smart glass, or smart glass with dimmer.
