Origins and Applications of Smart Glass / Dimmable Glass / PDLC Film

- Introduction to main ingredients:

The main components of Electronic Control Glass (PDLC) (also known as dimming glass, PDLC glass, electrochromic glass)#PDLC (Polymer-dispersed Liquid Crystal Film; PDLC Film), this idea of using a material mixed with liquid crystal and another medium as a light valve was proposed by C. Hilsum as early as 1976, but it was not practical until 1985 when J. L. Fergason used the emulsification method to successfully develop a solid-state thin film liquid crystal display, which prompted PDLC technology to begin to be widely researched and developed.

-Introduction to manufacturing process:

The NCAP method, also known as emulsification, emulsifies and disperses liquid crystals in a solution of water-soluble polymerizable polymers, and then coats it on a conductive substrate. After the solvent evaporates, it is then covered with another layer of conductive substrate. At this time, the liquid crystal droplets are surrounded by polymers and dispersed one by one. Raychem of the United States is the leader in developing NCAP technology and has transferred this technology to NSG of Japan, Saint-Gobain of France and Isoclima of Italy.

- Application introduction:

This material began to be used and known in the market, which can be traced back to the Italian designer.#GabelliniSheppard In the Park Avenue Apartment, New York City, designed in 1998, this design cleverly applied Electronic Control Glass in the bathroom, allowing bright light to naturally shine in every corner of the space while maintaining personal privacy.

In 2005, Qiwei Optoelectronics made electrical control films#direct-stick, which can be directly attached to existing glass. In 2010, it cooperated with well-known architect#LeeTzuYuan. Through cooperation, Electronic Control Glass applications were introduced across the entire exterior glass of the Taiwan Pavilion at the Shanghai World Expo, and the project quickly gained widespread attention. Later, this technology was also introduced into China and more manufacturers began to produce it.

- Conclusion:

#STARTEK It is good to see that Electronic Control Glass technology is widely used and popularized. This also means that the Electronic Control Glass industry will bring more diverse choices and more sophisticated technology and services to the public. However, in terms of application, in addition to considering price, consumers must also carefully evaluate material selection, construction methods, after-sales service and warranty, application of electrified hardware, electrical protection, etc.
