After Shenzhen Tianma acquired 34% of the equity of Guangdong Juhua Printing and Display Technology Co., Ltd. (hereinafter referred to as Juhua Company) wholly-owned by Huaxing Optoelectronics for 34 million yuan, the reporter recently learned that Juhua Company announced that it will cooperate with DuPont of the United States. , Japan's Sumitomo Chemical, Nissan Chemical, and U.S. Cody and other top companies in the world have signed strategic cooperation agreements.

According to the agreement, these upstream supporting manufacturers will fully support Juhua's material and process requirements in the development of printed OLED technology, and tailor-made related research and development equipment for Juhua.

Juhua's frequency layout in printed OLED display technology cannot be ignored.

At this time, a reporter from gambling.com exclusively interviewed Ma Songlin, deputy dean of TCL Industrial Research Institute and director of TCL Group’s Technology Center. He told a reporter from China Electronics News that it’s impossible to “do it alone” with larger printed OLED displays. Yes, it needs the entire industry chain to do it. In addition to upstream supporting manufacturers, Juhua also introduced South China University of Technology as shareholders, and introduced CLP Panda, Tsinghua University, relevant research institutes of the Chinese Academy of Sciences, Sun Yat-sen University, South China Normal University, etc. as important strategic parties to jointly promote printed OLED display technology develop. We have reached a consensus to innovate the mode of operation and build an open platform for public research and development.

The reason why upstream and downstream companies in the flat panel display industry chain are working together to print OLED display technology is not only because the technology is the development direction of the next-generation display industry, but also because after mastering the core technology, my country will break South Korea’s monopoly in the field of large-size OLEDs. In order to promote the development of the next generation of new display technologies, the development of printed OLED technology has been one of the key support projects in the "13th Five-Year" national key research and development plan.

Speaking of large-size OLED panels, Korean companies are pioneers in promoting their development. As early as 2013, LG and Samsung launched 55-inch OLED TVs for the first time in the Chinese market. However, due to large-size OLED panels facing mass production problems, Samsung subsequently slowed down the development of OLED TVs. In recent years, in order to gain the right to speak in the field of large-size OLED panels, LGD has continued to invest in this field, but cost and yield have always been the biggest problems faced by large-size OLED panels.

From the perspective of panel R&D technology, there are different technical routes for producing large-size OLED panels. Samsung uses RGB technology, while LGD uses white light + CF technology. In Ma Songlin's view, the evaporation process used by Samsung and LGD to produce OLED panels is very complicated, the material utilization rate is low, and the yield rate has not been high. Therefore, the evaporation process is not suitable for large-size OLED screens, and the industry urgently needs to develop new technical routes, and the printed display technology has very good development prospects.

Ma Songlin said that as early as three years ago, TCL began to deploy printing and display technology in advance. Compared with evaporation technology, OLED printing and display technology has to change in material selection and equipment. Printed display will break the bottleneck of large-size OLED mass production, which is an important direction for the development of display technology. It can eventually achieve "manufacturing displays like printed newspapers" and realize large-area, light, thin, and flexible display applications.

Ma Songlin told the reporter of "China Electronics News" that, more importantly, printing technology can greatly reduce the cost of OLED panels, even lower than the cost of LCD in the future. We hope to mature the new generation of printing and display technology in three to five years. Our goal is to make medium-sized OLED products in three years and mass production in five years. With the joint efforts of the upstream and downstream of the industry chain, if printing OLED technology can be done well, then my country will be able to break South Korea’s monopoly in the field of large-size OLEDs and become a leader in new technologies.
