JOLED filed for civil rehabilitation with the Tokyo District Court due to financing problems. As JOLED withdraws from the OLED business, it will close two factories in Japan and lay off about 280 employees. JOLED’s total debt is $257 million.

JOLED was born in 2015 by merging the OLED business units of Panasonic and Sony with the goal of accelerating the development and commercialization of mass production of OLED displays. However, due to a global semiconductor supply shortage, weak display demand, and extreme price competition, JOLED’s situation worsened and profitability was sluggish, so it filed for civil rehabilitation.

JOLED entered into an agreement with JDI(Japan Display Inc.) to support the revitalization of its technology development business at the same time as filing for bankruptcy. JDI said it has agreed to acquire JOLED’s technology development team and intellectual property, which consists of approximately 100 employees, to expand and accelerate its growth.

JOLED raised funds by receiving investments from companies such as Denso, Toyota and Sumitomo Chemical in 2018, and entered into a capital partnership with TCL CSOT in 2020. However, JOLED’s liabilities exceeded its assets in March 2022, with its production lines closed until the spring of 2021 due to the impact of the coronavirus, and continuing losses due to a global chip shortage. JOLED, which can only produce mid-sized OLED panels, has been hit hard by the corona as it is unable to capitalize on growing demand in other sectors.

According to the China Trend Report published by UBI Research, the schedules of TCL CSOT’s 8.5G LCD line T9 and 6G LCD line T5 are expected to be delayed.
In early July, the T9-1 was put into operation, but overall equipment orders for the ph-2 were delayed. According to the report, the schedule is expected to be delayed by about six months.
The schedule of the T5 line is expected to be postponed indefinitely. The T5 line was expected to begin mass production in the second half of 2023, but the schedule is indefinitely postponed and the mass production schedule is also uncertain.
Accordingly, TCL Chairman Li Dong Sheng, who is scheduled to visit Korea at the end of July, is expected to seek the understanding of Korean equipment makers due to the delay of schedules for LCD lines as well as consultations due to Samsung Electronics’ decrease in TV panel volume.
After visiting Korea, he is expected to visit JOLED in Japan to check inkjet technology. According to this visit, it is expected that the outline of whether the T8 line will be applied with inkjet process or deposition technology will be revealed in the future.

Ink-jet printing OLED, Next-generation large-area display

/in /by

Ink-jet printing OLED is attracting public attention once again as a next-generation large-area display.

At the keynote session of Finetech Japan 2017 held at Tokyo Big Sight as from May 5, CSOT in China prospected that next-generation large-area display would be ink-jet printing. York Zhao, the CTO of CSOT said that when the price of a new product is 1.2 to 1.3 times that of an existing product, it is the right time for the existing product to be replaced with new one. This principle has been applied when the CRT and PDP market was replaced by LCD. He added, “The price of large-area OLEDs should drop 1.2 to 1.3 times lower than LCDs to lead to a full-fledged OLED era, and ink-jet printing technology is the best way to assist the drop in price of OLED.”

<CSOT, York Zhao CTO>

In 2016, CSOT established the printing display alliance called “Guangdong Juhua printing display technology” together with Tianma, and has been participated by kateeva, DuPont, ULVAC, Merck and Jusung Engeering.

Following the announcement of CSOT, JOLED introduced various OLED panels in direct application of ink-jet printing. One of the most interesting devices was the ink-jet printing 21.6 inch 4K (3840 x 2160, 204 ppi) AMOLED panel produced in Gen 4.5 line. Yoneharu Takubo, the CTO of JDI said, “Since the establishment of JOLED, we have been improving ppi, and developed a technology to stably produce up to 204 ppi resolution. We are targeting 350 ppi and expand its product range from small and medium to large area to secure a variety of applications with ink-jet printing AMOLED. ”

<JOLED, Yoneharu Takubo CTO>

Ink-jet printing process is a technology under continuous development of major panel makers as AMOLED panel of RGB structure can be manufactured without dividing the ledger in the mass production line higher than Gen8. Also, material utilization efficiency is theoretically close to 100% to save the OLED unit cost. However, some issues arise that mass production has yet to be fully verified, and the efficiency and life span of soluble light emitting materials are inferior to those of deposition materials; hence, there has been undergoing active development in the manufacturers of light emitting materials, equipment and panels.

Ink-jet printing OLED becomes the center of public attention as a next-generation display technology, and when it will be commercialized is a matter of a question.
