- KOYJ CO., LTD. is a South Korea-based materials and components manufacturing company primarily engaged in the development, processing, and distribution of functional optical films and backlight unit components for electronic displays, as well as advanced specialty materials for secondary batteries. Founded in 2006 and headquartered in Chungju-si, Chungcheongbuk-do, South Korea, the company operates within the electronic components, chemical materials, and energy storage sectors, supplying display panel manufacturers, electronics assemblers, and battery materials producers across South Korea, China, and international markets.
The company offers a systematic portfolio of products and solutions across its core business divisions: optical coating sheets; prism sheets; diffusion sheets; protective films for liquid crystal displays (LCDs); composite optical sheets; light guide plates (LGPs) utilized in flat panel displays, televisions, monitors, and mobile devices; functional materials for Mini LED and OLED display applications; nano-metal oxide additives, specifically including nanoscale aluminum oxide particles formulated to enhance the structural stability, lifespan, and safety of high-nickel cathode active materials in lithium-ion secondary batteries; closed-loop industrial wastewater treatment and valuable metal recovery systems engineered to reclaim lithium, nickel, and cobalt from battery manufacturing streams; automotive electronic components, including power conversion devices; and professional aesthetic medical devices and functional skincare products.
In recent developments, KOYJ has executed a strategic transition to expand its business portfolio from mature LCD display optical components into the rechargeable battery materials market. The company developed and established production capabilities for nano-metal oxide cathode additives, initiating product evaluation and supply discussions with secondary battery material manufacturers in South Korea and China. Furthermore, KOYJ expanded its environmental technology initiatives by advancing resource-recovery processes for secondary battery production wastewater. To optimize its balance sheet and address capital impairment challenges, the company implemented comprehensive capital restructuring measures, which included a ten-to-one capital reduction and subsequent equity financing through rights offerings, while streamlining operations across its primary domestic facilities in Chungju and its manufacturing subsidiary in Nanjing, China.
