On November 28th, the world`s first batch of ceramic point sources for OLED evaporation developed and produced by SDGJ Advanced Materials Technology Group was delivered. As the core component of the display panel evaporation machine, its successful development marked the core equipment and equipment of China’s OLED industry. A major breakthrough was achieved in the localization of devices.
Ceramic point source products for OLED evaporation
In 2018, BOE cooperated with SDGJ to jointly carry out innovative research and development of point source. For this project, BOE’s senior leaders attached great importance to the grassroots technology and fully cooperated. Shandong Guojing also combined its own technology and product advantages, gathered resources and concentrated on research. After two years, it finally successfully developed a new type of ceramic point source product for the production of OLED panels. The equipment upgrade provides a brand-new solution, which realizes the independent control of the key components of major equipment.
The new ceramic point source developed by SDGJ adopts the industry's first composite ceramic heating technology, which can effectively solve the industry bottleneck of unstable rate and volatilization short-circuit in the evaporation process; at the same time, the point source has good temperature uniformity, stable temperature control, and resistance Good thermal shock, strong anti-pollution ability, strong surface insulation and other high-quality characteristics have attracted the attention and expectations of many domestic OLED manufacturers. The products have independent intellectual property rights and are at the leading level in the industry, breaking foreign monopoly.
SDGJCTO Liu Ruqiang said: “In the future, the development of OLED will present new models and new business formats such as popularization of market applications, diversification of product structure, clustering of industrial development, and chaining of technological innovation. China will carry out localization in the entire OLED industry chain. The development of ceramic point sources is the beginning of this localization trend.
"The R&D and mass production of ceramic point sources will promote the improvement of OLED panel production yield, production efficiency and cost reduction, and promote the rapid rise of Chinese OLED companies represented by BOE. I believe that in the near future, China will become the world's largest OLED production base. SDGJ will also work together with BOE and other internationally renowned companies to uphold the corporate mission of promoting change and leading progress, continue to innovate, increase research and development, develop more models and a wider range of ceramic point sources, and realize ceramics The comprehensive application of Point Source in the OLED field contributes to the development of China's OLED display industry!
SDGJ is a high-tech enterprise integrating R&D, production and sales of special ceramic materials, refractory metal products, evaporation source equipment and other products. The company has been approved as a provincial engineering technology research center, has undertaken 2 provincial science and technology development plans, 3 provincial independent innovation and achievement transformation major special projects, won 1 international science and technology cooperation award, 1 national key new product, provincial level One outstanding new product of technological innovation is "the leader of China's CVD technology and carbon ceramic industry".
