What kind of electricity does the electrified dimming Smart Glass need to pass through?

Privacy Dimming Glass is a new type of special photoelectric glass, also called electrooptic glass, electrified dimmable glass, electrified transparent glass, electronically controlled atomized glass, intelligent electronically controlled glass, etc. As the name suggests, it is a glass that uses electricity to control transparent and opaque states. So what kind of electricity does dimming glass use?

After more than ten years of development in China, the application of Switchable Privacy Glass has been very mature. In the process of development, it has been continuously upgraded. In addition, different manufacturers have different directions for the development of liquid crystal switchable films, so that different types of glass have appeared on the market in different periods. Dimmable glass. Although the appearance of Smart Tint Glass is the same, the internal structure is not the same. In terms of working voltage, the common ones are 70V, 65V, 60V, and the rare ones are 48V, 36V, 24V, etc. This also shows that the use of different dimming glasses requires corresponding power transformers.

You may be wondering, the voltage used by general dimming glass is about 65V. Why is that? This is mainly related to the physical properties of polymer liquid crystal molecules in the Smart Film. After testing by experts, it is found that the liquid crystal molecules are relatively stable when driven by a voltage of about 65V, which can not only achieve a good light transmission effect, but also avoid ignition and burnout.

So is there any dimming glass that uses 220V AC or 12V DC? The answer is no. The civilian electricity in our country is 220V alternating current, which is called high voltage (220V-240V) internationally, and such a large voltage is unsafe. The 12V vehicle-mounted DC power also needs an inverter to convert it into the AC power required by the Smart PDLC Glass before it can be used.

There is also low-voltage (100V-130V) civilian electricity in the world, which is used by the United States, Canada, Thailand and other countries, and is relatively safe. However, there are still dimming glasses that use 100V voltage. For example, a Japanese company has developed Frosted PDLC Glass that does not require transformer conversion for the Japanese market.

The civilian voltage of each country or region may be different, so the dimming glass for export needs to be equipped with different transformers. For example, Hong Kong and Macao are 220V, which is no different from the mainland, while Taiwan is 110V. It is important to note that several different voltages are used in the same country (such as Russia), so find out before buying.
