Cixi Shanglin Electronic Technology Co., Ltd.

Shanglin Electronics is a startup dedicated to the research and development as well as production of ultra-fine louvered privacy films. The company has a strong talent pool, technical expertise, and rich practical experience in areas such as micro-structure mold processing, optical-grade micro-structure transfer, and optical-grade UV resin synthesis. The privacy screens and films produced by the company for computers, smartphones, ATMs, and bank password devices reach world-class levels in terms of light transmittance, structural uniformity, and privacy protection. Ultra-fine louvered privacy film is a special type of functional optical film that is transparent from the front but opaque from the sides, used for screen content confidentiality. For example, when withdrawing money from a new ATM equipped with Shanglin's privacy film, the person standing directly in front can see the screen clearly, while someone looking from the side will only see a completely black screen, unable to discern any of the displayed information. The production of ultra-fine louvered privacy film is extremely challenging, requiring the coordination of sub-micron precision processing technology and optical-grade transfer technology. Currently, there are only six or seven manufacturers worldwide capable of producing this kind of film, with only those from the US, Japan, and South Korea reaching practical application standards. After years of focused research and continuous improvement in product quality, Shanglin Electronics has become one of the top global producers of privacy films, joining the ranks of leading companies from the US, Japan, and South Korea. Located in Cixi City, Zhejiang Province, on the southern shore of the Hangzhou Bay Bridge, Shanglin Electronics is close to the birthplace of celadon culture, the Shanglin Lake Yue Kiln Site, from which it derives its name. The company boasts comprehensive production facilities, including state-of-the-art imported ultra-precision machining equipment, imported optical film transfer production lines, and imported UV resin synthesis systems, positioning itself for long-term growth, brand building, continuous advancement, and future expansion.
