After Shentianma acquired a 34% stake in 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 learned recently that Juhua Company announced that it had signed strategic cooperation agreements with the world's top enterprises such as DuPont of the United States, Sumitomo Chemical of Japan, Nissan Chemical of Japan and Cody of the United States.

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

The frequent layout of Juhua Company in printing OLED display technology cannot be ignored.

At this time, a reporter from the gaming network exclusively interviewed Ma Songlin, vice president of the TCL Industrial Research Institute and director of the TCL Group Technology Center. He told the reporter of China Electronics News that large-scale printing of OLED shows that "single-handed" is not enough., It needs the entire industry chain to do it. In addition to upstream supporting manufacturers, Juhua Company also introduced South China University of Technology as shareholders, and introduced CLP Panda, Tsinghua University, relevant scientific research institutes of the Chinese Academy of Sciences, Sun Yat-sen University, South China Normal University, etc. as important strategic parties to jointly promote printing OLED display technology development. We have reached a consensus to innovate the mode of operation and build an open platform for public research and development.

The reason why the upstream and downstream enterprises in the flat panel display industry chain work together to print OLED display technology is not only because this technology is the development direction of the next generation display industry, but also because China will break the South Korea monopoly pattern in the field of large-size OLED after mastering the core technology. In order to promote the development of the next generation of new display technology, the "13th Five-Year" national key research and development plan has taken the development of printing OLED technology as one of the key support projects.

When it comes to large-size OLED panels, South Korea companies are the pioneers in promoting their development. As early as 2013, LG and Samsung first launched 55-inch OLED TVs in the Chinese market. However, due to the large-size OLED panel facing mass production problems, Samsung subsequently slowed down OLED TV research and development. 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 facing large-size OLED panels.

From the perspective of panel research and development 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 printing display technology has a very good development prospect.

Ma Songlin said that as early as three years ago, TCL began to layout printing display technology in advance. Compared with evaporation technology, OLED printing display technology has to change in material selection and equipment. Printing display will break the bottleneck of large-size OLED mass production, which is an important direction for the development of display technology. Finally, it can achieve "manufacturing displays like printing 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 size OLED products in three years and mass production in five years. With the joint efforts of the upstream and downstream of the industrial chain, if the printing OLED technology can be done well, then China can break the monopoly position of the South Korea in the field of large-size OLED and become the leader of new technology.
