Taicang Longsheng Optronics Technology Co., Ltd. (hereinafter referred to as“Longsheng Optronics”) was established in Taicang City, Jiangsu Province. It is a separate development, manufacturing, sales company and manufacturing of new materials for LCD PDLC film by Chiefway Optronics in accordance with the future strategic development plan of PDLC film. There are 34 employees, including 2 doctors, 3 masters, 21 undergraduates, 5 specialists, and 3 others.

The wide-temperature PDLC film independently developed and produced by the company has obtained 34 patent certifications and energy-saving certifications, filling the gaps in the international and domestic automotive smart glass and architectural energy-saving glass fields. The company participated in the compilation and review of the national standard (GB/T 35847-2018) of "Electro-induced LCD Film PDLC Glass". The combination of this material and glass not only improves the shading performance of the glass, but also can reasonably control the sun's rays entering the room and reduce the air conditioning load caused by solar radiation from the outer window.

The company's series of products based on the integrated development of dimming film materials include: dimming film series, glass dimming screen, transparent dimming screen, outdoor sunshade dimming transparent LED. At the same time, it has independently researched and developed intelligent electronic controls dedicated to supporting dimming films and intelligent power supplies that provide stable current input. These products have been used in the building materials industry, decoration fields and cultural media fields. We position the unique value of our products with new materials and new media, and bring a different glass display and user experience.
