 Tcl30 billion yen shares in joled to accelerate the industrialization of printing OLED Technology

This is the latest action of TCL technology in OLED industry, and the most important thing is that the two investors will carry out in-depth technical cooperation in ijp-oled (inkjet printing OLED) field.

Zhang Hong, research director of TV Department of sigmaintell, told 21st century economic news: the investment in joled is conducive to enhancing TCLs R & D capability in the new technology field, accelerating its layout for the next generation of display technology, especially occupying a certain first mover advantage in large-scale OLED product technology, and improving the companys brand efficiency and overall competitiveness.

However, there are still many problems from printing like a newspaper OLED panel. It will take at least two years for [Chinese manufacturers] to really achieve mass production, Zhang Hong told reporters

TCLs printing ambition

TCL technology has been in the panel industry for a long time. In 2009, TCL Huaxing established and invested heavily to establish multiple LCD and flexible AMOLED production lines. And continue to invest in the next generation of new display field, promote the flexible printing display OLED / qled, micro led and other new display technology routes.

As early as 2014, TCL aimed at printing and display technology, established Guangdong Juhua printing and display technology Co., Ltd. in combination with Tianma microelectronics and other manufacturers, as well as South China University of technology and other universities, to engage in the development of printing and flexible display technology. At present, TCL has developed a 31 inch 4K printed h-qled display screen, and developed a 31 inch flexible prototype for inkjet printing.

The industrialization of technology is naturally inseparable from upstream and downstream cooperation. After the establishment of Juhua company, TCL signed strategic cooperation agreements with DuPont, Merck, Sumitomo, Nissan and kateeva. These partners will support Juhuas material and process requirements in the development of printing OLED technology, and customize relevant R & D equipment for Juhua.

Meanwhile, TCL also invested in kateeva, a large-scale inkjet equipment company. TCL Huaxing had contact with joled for a long time, so that three years ago, TCL had heard that TCL would invest in joled. Now, TCL and joled finally formally join hands.

Cui Jilong, general manager of Beijing Dixian, told 21st century economic news that compared with BOEs multi-point layout of future technology, Huaxing has always been focused on Printing OLED. Printing OLED technology is still in the early stage of development, and there is basically no complete production performance. In this case, the relatively advanced overseas enterprises are a good cooperation option, which can promote the industrialization of printing OLED.

Looking at joled, in 2015, joled was invested and established by Sony, Panasonic and Japan Industrial Innovation Agency (incj), mainly integrating the OLED departments of these leading enterprises and focusing on the research, development and production of printed OLED panels. Japanese enterprises have always been good at tackling technical difficulties. Joled has mastered the worlds leading OLED material printing and film forming technology, oxide semiconductor technology and flexible / winding panel related technologies.

According to the public information, in 2017, joled launched the first printed OLED panel, with a size of 21.6 inches and a resolution of 4K, which was supplied to ASUS; in 2019, the worlds first ink-jet printing OLED panel production line, g5.5 nengmei production line, which was invested by joled, began operation and trial production. In the same year, joled also invested 25.5 billion yen (about 1.54 billion yuan), after the construction of OLED in Chiba County, Japan The segment die set processing plant mainly produces 10-32 inch printed OLED display modules, which are mainly used in automobile display and high-end display markets, and is expected to be mass produced in 2020.

This also means that on the basis of nengmei and Chiba plant, OLED printing of joled will usher in an important stage of mass production this year. At this time, TCLs investment is just at the right time. For joled, it also needs industrialization funds and market assistance.

Seize the high point of upstream Technology

Not long ago, Li Dongsheng said: Japanese enterprises have maintained an absolute global advantage in the field of semiconductor materials for a long time. Japan also has a group of family enterprises that have long been focusing on research and development in a specific technology field, with high technology content, leading position in the industry and small company scale, which is very suitable for investment cooperation and M & A.

He suggested that the development of domestic new display industry could strengthen technical cooperation with Japan, Europe and other countries and regions with advantages in the field of new display materials and equipment. The background of the proposal is that the key materials and core equipment in the panel industry of China are still heavily dependent on imports. For example, the domestic market share of new display key luminescent materials is only about 5%, and that of LCD and OLED core materials is only 47% and 17%, respectively.

At present, in terms of large-scale OLED, Korean LGs panel company LGD is still a top priority, and Samsungs SDC plays a leading role in small and medium-sized OLED. Chen Jun, deputy general manager and chief analyst of Qunzhi consulting, told 21st century economic news: at present, the OLED investment in the global large-scale field is still dominated by Korean factories, and the OLED technology investment around large-scale products will continue in the next few years. In the small and medium-sized field, according to Qunzhi consulting data, the global OLED panel demand in 2020 is about 520 million pieces, with a year-on-year growth of about 16%, among which the mainland manufacturers are expected to ship about 83 million pieces, with a year-on-year growth of about 91%.

The high generation OLED production line technology of SDC layout is printing OLED technology, which is expected to usher in mass production in the second half of next year. However, the production capacity in the early stage is limited, and the process technology still has a large space for improvement. Zhang Hong introduced to reporters.

She also said: for Chinese manufacturers, the reserve of talent technology is still relatively insufficient, and it will take at least two years to realize the real mass production. The difficulties are mainly manifested in two aspects: first, the upstream material supporting is not perfect; second, the process technology is not mature.
