About Shanghai Longsheng Optoelectronic New Materials

Shanghai Longsheng Optoelectronic New Materials Co., Ltd. is a high-tech enterprise focused on the research, development, production, and sale of Polymer Dispersed Liquid Crystal (PDLC) film materials. The company provides comprehensive solutions for PDLC product development and manufacturing, primarily for the automotive sector. The core products are PDLC liquid crystal dimming films, which can switch from opaque to transparent when an electric current is applied. These films are used in automotive applications such as sunroofs, side windows, and rear windows to provide intelligent dimming, privacy, thermal insulation, and UV protection. The company has developed its technology over 20 years and states its proprietary coating equipment allows for a film with low haze and high light transmittance. Longsheng Optronics has an annual production capacity of three million square meters of rolled materials and two million square meters of finished sheet films. The company's products have passed the 5,000-hour automotive glass test for OEMs and the Fuyao Group, a major automotive glass manufacturer. It holds over 30 patents in China, the United States, Japan, and South Korea and has obtained certifications including IATF 16949, ISO9001, and ISO 45001. In late 2023, the company announced the completion of a Series B+ financing round of nearly 100 million RMB.
