Recently, located in Jiading District Waigang Town, Shanghai Longsheng Optoelectronic New Materials Co., Ltd. was officially put into production, the company is one of the few factories in China with independent research and development and production of dimming film raw film capabilities, the establishment of intelligent dimming film industry base project after the production, can achieve an annual output value of 600 million yuan.
"The middle of this glass is equipped with the LCD dimming film PDLC product produced by our company." In the moment of lightly pressing the remote control button, the glass in front of the eyes becomes a piece of fog, and the rear scenery is "isolated", Zhao Yang, the marketing manager of Longsheng Company, told Xiaojia that this is mainly to control the electric field, and its working principle is: when powered on, the polymer liquid crystal material in the liquid crystal membrane is arranged in an orderly manner, and the glass becomes a transparent effect; when the power is cut off, the liquid crystal molecules become frosted in a disordered state. This dimming technology is widely used in window advertising, multimedia curtain walls, conference rooms and other building interior and exterior decoration environments.
In recent years, the application scenarios of dimming products have expanded to the field of high-end automobile manufacturing, and the new glass products represented by canopy glass and dimming glass have been continuously launched and successively loaded into the car, creating a variety of scenes of "living space", when there is strong light, the color can be dimmed to isolate ultraviolet rays; when the weather is appropriate, it can also be adjusted into transparent glass to use; due to the characteristics of the LIQUID crystal film interlayer, the dimming glass can also realize the function of the projection screen, presenting high-definition images on the glass.

"With the development of the 'new four modernizations' of automobiles, the use of canopy glass will become a trend. On the one hand, relying on the lightweight attributes of canopy glass, weight reduction and energy saving, it saves parts costs for automakers, reduces materials such as drive units and execution units, and can create differentiated selling points; on the other hand, for glass manufacturers, it can greatly enhance the added value of their products, and it is more aesthetic and spatial value for consumers. Zhao Yang said that with the rapid penetration of electric smart cars and the gradual application of dimming glass, the development of the dimming film industry has become more exciting.
It is reported that Longsheng Company currently mainly serves customers such as Fuyao Group, Yaopi Glass, French Saint-Gobain, Webasto, Dutch inalfa, Pier Golden Shield, Shanghai Daimei and so on. The dimming film products produced by the company have been successfully applied to the skylights, sky curtains and side windows of a number of new energy vehicles such as BMW IX series and Lantu FIEE.
Renderings of the plant
According to the plan, Longsheng Company will build an intelligent dimming film industry base of more than 17,000 square meters in Waigang Town, the new production line can achieve semi-automated production, the production capacity will be increased from 150 pieces / day to 1200 pieces / day, after reaching production in 2025, the annual output value will exceed 600 million yuan.
