JSYK, a leading photoresist manufacturer in China, focuses on the development and manufacture of photoresists for the manufacture of high-generation LCD and OLED displays.
The main products include TFT-PR positive photoresist, lithography process auxiliary materials (developing solution, thinning solution, cleaning solution, etc.), BM resin, etc. The Korean subsidiary mainly deals in color photoresist. At the same time, the company has mastered the research and development technology and production process of color photoresist and TFT-PR photoresist, and the resources of world-renowned major customers. The company's photoresist products are mainly used in high-generation LCD displays and OLED displays.
As far as customers are concerned, JSYK's current overseas customers for photoresist business are not only LG Display, but also Samsung. The photoresist needed by Samsung is more expensive and more difficult than the current LCD photoresist. After years of technology accumulation, the company has a number of photoresist-related patents.
JSYK's 2020 annual report shows that the company's display photoresist has maintained its business scale for LG display and other original panel customers, and has actively developed new products and opened up customers in mainland China and Taiwan, and has made significant progress: new development The photoresist for OLED display has begun to supply LG display’s Apple electronic product production line, and has been tested and certified by large domestic panel manufacturers such as China Star Optoelectronics. At the same time, in 2020, it has opened up large panel manufacturers such as BOE, China Star Optoelectronics and Huike.
On September 14, 2020, JSYK issued a fixed increase plan stating that the company plans to raise funds not to exceed 1.2 billion yuan, and the raised funds will be used for a new generation of electronic information material localization project-photoresist and photoresist supporting reagent project , A new generation of large-scale integrated circuit packaging special materials localization project, an annual output of 12,000 tons of electronic grade sulfur hexafluoride and an annual output of 2,000 tons of electronic grade carbon tetrafluoride for semiconductor production line technological transformation project and supplementary working capital.
