[China Trend Report] TCL CSOT’s T8 Project to Invest in Generation 8.5 Inkjet Printing Technology

According to the โ€˜China Trend Reportโ€™ published by UBI Research, TCL CSOT plans to apply the generation 8.5 inkjet printing OLED technology to the T8 line. It is expected that some layers will be formed by vapor deposition in the inkjet printing method rather than the complete inkjet printing method. The location is likely to be Guangzhou.

TCL CSOT’s T8 line was scheduled to start construction in March 2022 using the inkjet method, but there were rumors that the schedule continued to be delayed due to investment scale and yield issues. There are also talks about the project being canceled altogether. However, it seems that TCL CSOT has continuously improved its technology by continuously collaborating with JOLED. They also announced related contents at DTC 2021 held in November 2021.

It is is expected that mainly OLEDs for IT and automobiles will be mass-produced at the T8 line. The investment schedule and details of the TCL CSOT T8 project can be found in the โ€˜March China Trend Reportโ€™.

 

Samsung Display’s QD-OLED applied to Sony’s TV and DELL’s monitor

QD-OLED panels, which are being mass-produced from the second half of 2021 at Samsung Display, will be applied to new products for Sony and DELL.

Inkjet might take advantageous position for Gen11 super large OLED mass production line!

Toshiaki Arai, chief technologist of JOLED and James Lee, deputy chief engineer of TCL made presentations for the solution processed OLED on March 7 at the ‘4th OLED Korea conference’ held at Novotel Ambassador Hotel in Gangnam, Seoul, hosted by UBI Research.

Toshiaki Arai, chief technologist of JOLED announced that JOLED will focus on the medium-size OLED market for 10 ~ 30 inch tablets with solution processed OLED. He explained “OLEDs for mobile devices are currently targeting over 500 ppi and at least 800 ppi, which is hard for today’s printing technology. However, current printing technology is competitive enough since the medium-size OLED for tablets is 300 ppi levelโ€.

He also added, โ€œWhile it is required to divide the mother glass with the deposition technology currently in use, JOLED’s oxide TFT and solution process OLED can be adopted to Gen 8.5 as well as Gen 11 without cutting the mother glass. Thus, we expect panel production to be increased significantly.

James Lee, deputy chief engineer of TCL commented that the next-generation premium TVs are to implement 70-inch or larger screen, full black representation, high-definition at 8K resolution, and design differentiation such as slim & flexible. He said โ€œsolution process technology enables large RGB OLED implementation, which can improve image quality and reduce cost by using less material. TCL is currently developing solution process technology, which might be expected to be applied to its planned Gen 11 factory. ”

He commented “OLED TV prices are now approaching the price of LCD TVs based on 65-inch standards. In 2021, OLED TVs and LCD TVs will not differ in price, and OLED TVs will become the mainstream of the premium TV market. ”

Also he emphasized “Gen11 OLED needs to improve mura (unevenness) free technology, but it can produce six sheets of 75-inch OLED panels, and it is three times the production volume of GEN 8.5, with a cutting efficiency rate of 95% or more. In order for OLED TV to become the mainstream of the TV market, it is necessary to establish Gen 11 solution process OLED factory. ”

At the ‘IMID 2017 Business Forum’ held in COEX, Seoul from 18th to 19th, Toshiaki Arai, chief technologist of JOLED announced JOLED’s printing technology and future road map.

<JOLEDโ€™s Toshiaki Arai chief technologist>

Toshiaki Arai, chief technologist stated that a stable jetting technology at 220 ppi level has been currently secured; high resolution OLED with more than 300 ppi has been developed at Gen 8.5 but there are some issues such as jetting accuracy and stability.

Toshiaki Arai introduced TG-TAOS (top gate-transparent amorphous oxide semiconductors) TFT, which will contribute to saving the unit cost of OLED with excellent performance at low price.

He also announced the future strategy of JOLED, stressing that, instead of small and large OLED dominated by South Korean companies, the middle-sized OLED for tablet and monitor with more than 200 ppi. Joled is the only OLED panel maker that unveiled its 21.6 inch 4K RGB OLED in 2017, using printing process, and has pilot launched.

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

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.

Large Size OLED Panel Technology Match, โ€˜WRGB vs. Solution Process RGBโ€™

Large size OLED panel is currently being mass produced by LG Display using WRGB method, and investment in this method for large size panel is being considered by OLED panel latecomers. Another method that can be used to produce OLED is RGB method. In 2013 Samsung Display mass produced using RGB method but halted the process due to problems in yield rate and technology. However, recently as key display companies are developing RGB method using solution process for large area OLED panel, latecomers are having to make a difficult choice in process selection.

 

OLED specialized panel company JOLED, established by JDI, Sony, Panasonic, and Innovation Network Corporation of Japan (INCJ), is aiming for mid-to-large size OLED panel production using solution process. Additionally, other companies including AUO, BOE, LG Display, and Samsung Display are developing large size OLED panel using solution process technology. In 2013, AUO presented 65 inch FHD panel that used solution process technology, and BOE revealed 30.5 inch FHD panel. Panasonic also presented solution process applied 4K panel.

 

According to 2015 White OLED Display Annual Report, published by UBI Research, WRGB method has an advantage in high mass production potential as open mask is used. However, due to the stack structure and color filter use, it has a disadvantage of increased panel production cost. On the other hand, the materials and process technology for solution process are not yet mature, but has the advantage of being able to produce large size OLED panel in Gen 8 size or larger without glass cutting using RGB method. It also can reduce the production cost as the material efficiency is high and does not require color filter.

 

At present the mass produced glass area by the latecomers forecast to manufacture large area AMOLED panel is expected to occupy approximately 30% of the total large area OLED market in 2020, and latecomersโ€™ choice in technology investment will be a key point. Therefore, the large area panel technology leadership will be decided on whether WRGB and solution process methods can solve the issues that each has.

JOLEDโ€™s Intense Start, Mass Production is When?

At Finetech Japan 2015 (April 8-11, 2015), JOLED gave a presentation for the first time since its inception and drew much attention.

 

JOLEDโ€™s speaker Tadashi ISHIBASHI gave a presentation on JOLEDโ€™s target market and application technology under the title of โ€œThe Evolution of OLED Manufacturing Technology by JOLEDโ€. During his speech Ishibashi revealed โ€œJOLEDโ€™s target market is 10~30 inch mid-size OLED panel and ultimately to form new market through flexible displayโ€ and that โ€œtop emission, RGB printing, color filter, and ITZO backplane of self-align structure will be applied for key technologyโ€.

 

Furthermore, by forming all RGB through solution process, macro-cavity effect via thin half-transparent cathode, and minimizing interference of other colors and external reflection using color filter, JOLED explained that high purity color reproduction is possible. It is analyzed that this means that they absorbed Sonyโ€™s characteristic super top emission technology. Backplane is top-gateโ€™s TAOS (transparent amorphous oxide semiconductor) and Ishibashi added that it is also possible to reduce cost by minimizing investment amount by applying 5 mask self-align structure.

 

Regarding flexible display, JOLED used the technology that was applied to 9.9 inch qHD panel (revealed by Sony in 2012) which used white OLED and color filter as an example but reported they are currently developing technology to produce flexible display using solution process RGB.

 

From the presentation it is estimated that for JOLEDโ€™s mass production, Sonyโ€™s OLED panel structure and Panasonicโ€™s RGB printing technology will be combined and applied. Although detailed investment timeline was not revealed, as mass production application technology and target have been publicly announced, investment in near future is anticipated.
