According to the ‘China Trend Report’ 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 ‘March China Trend Report’.

While LG Display is recording poor performance in first quarter of this year, it is going to strengthen its competitive edge in OLED display, which is its main business. Because it is expected that Chinese LCD will continue to make inroads into supplies this year, Samsung Display is planning to bring about results through high-value OLEDs that are highly profitable.
“It seems that large OLED business will take up more than 30% of TV business in 2016 through changes in customer and high-end position.” said Seo Dong-hee, chief financial officer of LG Display, during a conference call on the first quarter of 2019.
“Although some fixed expenses are also expected in second half of this year due to preparation of (Guangzhou OLED fab) production infrastructure as planned, we will increase profit contribution starting from 2020.” said a representative for LG Display.
■ It is difficult to rebound in second quarter performance…compete with high-value OLED in second half.
LG Display also expects that its second-quarter earnings will continue to worsen market conditions due to oversupply of LCDs and lack of IT products. Consensus of second quarter’s performance that F& Guide is estimating is $5.58 trillion (5.8181 trillion KRW) in sales and $16 billion (16 billion KRW) in operating loss.
However, it is expecting that it will produce results starting from second half of this year due to operation of OLED production lines that are located in Guangzhou, China, and release effects of transparent and automatic OLEDs.
“We believe that Guangzhou fab will operate successfully during first half of this year. “We are also preparing to apply MMG (Multi Model Glass, which is a method that is produced by combining 55-inch and 65-inch panels) to Guangzhou and Paju fab.” said a representative for LG Display.
Furthermore, transparent OLED products will be released in second half of this year and will expand additional demands. “We are currently working with variety of customers in commercial business.” said a representative for OTO, “Auto is already making more than 1 trillion won in sales through LCD. During this year, you will be able to see vehicles with plastic OLEDs. Although it is difficult to mention exact numbers, South Korea has received a large number of orders for displays for vehicles that employ POLEDs. We believe that orders will also gain considerable momentum when cars with POLED are successfully released this year,” he stressed.
FineTec Receives Intent for Purchase of OLED Bonding Equipment from Chinese Firms(NEWSPIM)
(Full text of article: http://www.newspim.com/news/view/20190424000218)
While demands for OLED panels are increasing rapidly due to the resumption of investments in Chinese OLEDs this year, FineTec is trying to expand its supply of bonding equipment to Chinese display-specialized companies.
FineTec made an announcement on the 24th that it recently received orders from Chinese display company BOE for OLED composite bonding equipment and received LOI (Lent of Purchase of OLED bonding equipment) from CSOT.
FineTec is planning to supply CSOT with equipment dedicated to chips on plastic and COP-COF (chip on film) and other composite equipment that can be produced simultaneously. It is predicted that it will sign a contract with CSOT to supply bonding equipment after discussing detailed timing of supply.
In addition, FineTec, which is currently seeking to diversify its suppliers to China, is planning to strengthen its competitive edge in operation such as OLED composite bonding equipment for CSOT starting with this contract.
“Chinese OLED panel manufacturers are increasing their market share thanks to government support and Chinese Smartphone manufacturers’ promotion.” said a representative for this company. “FineTec is planning to focus on improving performance by securing orders from Chinese suppliers as China is actively seeking to increase its market share in OLED.”
It is also expected that FinTec’s combined bonding equipment will expand its competitive edge in markets in China. Although FinTec had about 10% of orders for bonding equipment that was placed in China three years ago, percentage of orders from Chinese display companies such as BOE and Visionox increased to 26% last year due to increased demands for composite equipment.
“We are currently converting variety of display panels from facilities that are targeted at specific types of panels from China and around the world into multi-functional equipment that can be produced at the same time.” said a representative for Samsung Electronics.
OLED is also worried about oversupply…” China factory size, twice that of Korea.” (YONHAP NEWS)

Following LCD panels, there are predictions that oversupply can become a reality for OLED panels.
Concerns are growing as South Korean companies plan to grow OLEDs into new “cash cow” instead of LCDs that China has taken the lead.
According to a recent report released by Hana Financial Management Research Institute on 21th, the number of OLED panel factories currently under construction in China is 419,000 sheets per month, about twice the amount of 225,000 sheets per month, which is the size of South Korea’s expansion.
According to the report, China’s BOE, which ranks first in LCD panel market, is going to increase its size to 144,000 panels. In addition, Chinese panel manufacturers such as CSOT, Visionox, and TCL are also scrambling to expand their facilities on a large scale.
Among South Korean companies, LG Display is set to operate its 90,000-unit monthly plant in Guangzhou, China, and it is expected that there will be a total of 45,000 panels per month in Paju.
Industries predict that size of OLED plant that will be built by Samsung Display in Tangjeong, South Chungcheong Province, will reach 90,000 sheets per month.
“As speed of expansion of OLEDs in South Korea and China is much faster than rate of increase in demands, there is a high possibility that oversupply will worsen.” said Joo-wan Lee, a researcher.
The screen shield that caused controversy over faulty Galaxy folds…Why do I need it? (Yonhap news)
(Full text of articles: https://www.yna.co.kr/view/AKR20190421010700017?input=1195m)
Samsung Electronics’ first foldable Smartphone was embroiled in controversy over its screen defects even before it was released. Samsung Electronics explains that this happened because early users removed “screen protection film,” which can be misunderstood as screen protection film.
<Samsung Electronics [Samsung Electronics Co., Ltd.]>
According to industries on the 21st, current Smartphones are going to protect displays by attaching cover windows with reinforced glass material on top of OLED display panels.
OLED panels themselves are very thin like vinyl and are weak against external shocks. Plastic OLED (Plastic OLED) that is used for foldable Smartphones is more vulnerable to scratch. However, it can’t put glass, which is a material that doesn’t fold, so it is finished by applying film of plastic material.
“Although screen protection films that we already know are additional products that prevent scratching, protective films that are used for flexible displays are very important for displays.” said Professor Hak-seon Kim of UNIST, who is a former vice president of Samsung Display. Ok-hyun Jeong, an electronic engineering professor at Sogang University, also said, “The fact that we took out a protective film from PLED is tantamount to ripping off the display parts themselves.”
OLEDs emit light as organic materials, and due to their characteristics, they are very susceptible to oxygen and moisture components. When a thin panel itself is subjected to strong pressure during a screen’s opening, it can cause the screen itself to become indigestion due to moisture in an empty space.
Plastic has a weaker hardness than glass, making it easier to scratch the surface.
In addition to screen glitches, the media that received Galaxy Folders for review such as Bloomberg and Derverge points out that the protective film is easily dented or scratched. One reviewer said, “I tapped the screen with my fingernails, but there are still permanent marks.”
Some point out that there is a gap between the protective film and the display, which makes it easier for dust and others to get rid of it. One reviewer suggested a photo showing the gap between the screen’s protective screen and bezel, suggesting that it could be misleading.
Due to this reason, Samsung Electronics explained that its screen shield is for ‘replacement’. Since there is a higher chance of damage such as scratch than conventional glass, they were made so that they could be replaced at that time. However, users should not replace them directly and go through a service center.
Experts point out that such precautions should be sufficiently notified to consumers before the launch, and that early users also need to follow basic precautions as they use first-generation products.
Jeong said, “Samsung Electronics seems to have lacked notice of screen protection. “We need to strengthen advance notice when it is officially released.” said a person who dropped it from the company, which is about 100 grams more than normal Smartphones, risks further damage when it is dropped from the same location. This part also requires the user to pay attention,” he pointed out.
“Since the film itself is a plastic material, even if it is attached with protective film, it can be pierced and torn if exposed to sharp needles, unlike glass,” Professor Kim said. “In fact, these precautions should be properly introduced when selling it.”
SK is investing in OLED business? (etoday)
(Full text of articles: http://www.etoday.co.kr/news/section/newsview.php?idxno=1747027)
SK Corp. is considering investing into OLED material business. As OLED markets are rapidly growing, industries that are made of OLED materials are also increasing.
According to mid- and long-term management plan data that SK Corp. held a corporate briefing for analysts of securities companies on Wednesday, SK Corp. is also reportedly considering investing in OLED materials to expand its material business.
SK Corp. has set a mid- and long-term strategy for its material business to expand its high-growth area by utilizing its current material platform.
For OLED materials, LG Display is planning to develop its own technologies by linking current SK Trichem’s technologies such as precursors and others while also considering investing in them.
Industries predict that SK Corp. will be able to expand its business through investments as it is an investment-type holding company.
For battery materials, which are planning to enter markets with high-entry barrier materials through partner companies’ cooperation and investment in technology holding companies, it has quickly entered the market by investing 270 billion won into shares of related companies.
SK Corp. previously acquired the stake in Watson, China’s No. 1 company that manufactures the second-order essential part of the battery, in November last year.
A reason why SK is showing interest in OLED markets is because OLED markets are growing rapidly.
According to a market research company called Ubi Research, size of OLED display market was estimated to be $28.31 billion (31.9568 trillion KRW) last year, which is a 7.1% increase year-on-year and is expected to grow to $32.3 billion (36.457 trillion KRW) this year.
It is expected to grow to $59.5 billion by 2023.
As a result, many other companies are working on OLED materials. Earlier this month, LG Chem stepped up its related business by acquiring material technology for “Solid Organic Light Emitting Diodes,” a key platform for next-generation displays, from DuPont in the U.S.
Doosan also established a new company through division of its business sector to strengthen its material businesses such as OLED.
“We have no specific plan to invest in OLED materials yet.” said a representative for SK Corp.
China TCL will invest RMB 42.8 billion (US$ 6.71 billion) in Shenzhen to establish a factory for large-area OLED panel production. According to South China Morning Post, TCL recently announced that it will produce 90,000 units on the basis of 70-inch panel in the new production line of Gen 11 (3370 mm x 2940 mm) with the goal of mass production in March 2021 in the data submitted to the Shenzhen Stock Exchange. The main products are to be known as 65-inch and 75-inch OLED panels, and 65-inch, 70-inch and 75-inch display panels with 8K resolution.
TCL will form a partnership with the China Development Fund for the necessary financing and will set up a new production line at TCL’s semiconductor subsidiary with RMB 20.3 billion.
Large-area OLED to be produced by TCL is expected to adopt solution process RGB. At the ‘4th OLED Korea conference’ hosted by UBI Research in March, James Lee, deputy chief engineer of TCL mentioned about the development of next-generation premium TV with the screen size of 70-inch or more and 8K resolution, based on the solution process.
Lee said, “The price difference between OLED TV and premium LCD TV is estimated to be reduced to 1.4 times when the price of large-area OLED panel is lowered by the operation of LG Display’s Gen 10.5 plant in 2020. We are developing solution process technology for large area OLED and it will be applicable to Gen11 factory. ”
Gen 11 production line is capable of producing six sheets of 75-inch OLED panels, being able to achieve a yield three times higher than Gen 8.5 production line and a cutting efficiency of over 95%. In addition, it is possible to produce large-area OLED panels with a real RGB structure instead of the WRGB structure when solution process is applied. Based on this, TCL emphasized that the construction of the Gen 11 solution process OLED mass production line is essential. Meanwhile, TCL has jointly established JUHUA Printing Display Technology with Tianma, a Chinese company, in 2016 through CSOT, which is a subsidiary of TCL, and is continuously developing the inkjet printing process by a Gen 4.5 R&D pilot plant.
At the 6th China Information Technology Expo (CITE 2018) held in Shenzhen, Guangdong Province, China from April 8 to 11, 2018, a number of panel makers and set makers exhibited notch-designed display panels and smart phones.
In CITE 2018, five panel manufacturers exhibited in CITE 2018; BOE, EDO, GVO, Tianma and CSOT. Among them, BOE, Tianma and CSOT exhibited notch-designed display panels.
First, BOE introduced 6.2-inch OLED panels applied with notched design. The OLED panel exhibited by BOE has a resolution of 2992 x 1440 with 537 ppi and 400 nit brightness.
LCD panels also began to adopt Notch Design. Tianma presented a 6.18-inch LCD panel with a notch design. CSOT also exhibited two 6.25-inch LCD panels and a 6.18-inch LCD panel applied with notched design.
<’Notch design’ display panels exhibited in CITE 2018>
Vivo, a Smartphone maker, also exhibited the X21 with a notch design. The X21, released in March, has a resolution of 1080 x 2280 with 6.28 inch screen.
<Vivo X21, OLED Smartphone with notch design>
Since Apple first unveiled its OLED smart phone with the notch design on iPhone X, a number of smart phone makers such as Vivo, Oppo, and Huawei have begun to release OLED smart phones. In this exhibition, many panel makers presented a large number of LCD panels to which Notch Design is applied. Attention is growing whether Notch Design can become a trend in the small and medium sized display market in 2018.
CITE, an electronics trade show held in China on April 10, 2018, had a relatively lukewarm atmosphere with significantly fewer visitors than last year. It seems to have been influenced by the lack of special IT issues, compared to last year when it was crowded with the attention of many general visitors.
Especially, there were no new products on the TV appliance side. Most of the exhibitors displayed the same products as those of last year or 2018 CES. On the other hand, LG Display unveiled its 88-inch 8K OLED TV, which had been hiding in its own booth, at the front of the booth. CSOT also showcased OLED displays made with printing technology that had been publicized several times during several conferences. 8K OLED TV is to be the future of the high-end premium TV as it clearly shows the advantages of OLED display such as contrast ratio, sharp image quality and color reproduction through large screen. CSOT’s 31-inch display is meaningful because it exhibited the results of CSOT’s printing OLED technology development. It is preparing for a new investment of about 20K TV line next year. The exhibited product was manufactured by using top emission Ink-jet printing technology to oxide TFT. The peak brightness is 150 nit at 144 ppi.

Vivo, which was the first to unveil the smart phone X21 with a built-in fingerprint sensor, displayed only the X21 model at its booth. As a result of the actual registration testings, the fingerprint was recognized several times compared to the existing fingerprint registration, and the test recognition rate was not bad, but the response speed was slightly slower than opening the screen with the home button. In addition, most panel makers exhibited displays similar to the notch design of the iPhone X, which created various issues over the past six months, and set makers such as Vivo and Oppo released similar notch type smart phones. According to one official of some panel maker, the response to the design is not positive, but he said the company made it along with Apple. In his personal opinion, he preferred full screen design. Despite the sluggish performance of iPhone X, it still shows Apple’s strong market influence that the smart phones of the similar designs were released.
BOE, which started the operation of its Chengdu factory in 3Q 2017, exhibited various OLED panels made using plastic substrates. One official of BOE expressed confidence that it is only Samsung Display and BOE that can mass produce flexible OLED panels using plastic substrates across the globe.
■ Flexible OLED is expected to ship 480 million units in 2019, surpassing Rigid OLED shipments.
■ Full-screen OLED among Flexible OLED is expected to have an average market share of 78.3% by 2022, dominating the market.
■ Foldable OLED is expected to ship in earnest from 2019.
Flexible OLED shipments are expected to exceed rigid OLED shipments in 2019. According to the ‘2017 Flexible OLED Annual Report’ published by Ubi Research, flexible OLEDs are expected to ship 480 million units in 2019, surpassing 409 million units of rigid OLED shipments. In addition, flexible OLED shipments will grow at a CAGR of 41% starting in 2018, reaching 1,285 million units in 2022 with forecasted revenue of US$ 59.4 billion.
<OLED Market Share Forecast by Substrate in 2018 ~ 2022>
Recently, as the hardware technology of mobile devices has been leveled up, set makers targeting the premium market are trying to differentiate their products by adopting OLED. Especially, set makers are beginning to introduce flexible OLED capable of full screen, as the needs of consumers who want a wider screen in mobile devices (even in the same sizes) on the increase.
Accordingly, panel makers are continuing to invest in flexible OLED mass production. Since Chinese panel makers such as BOE, CSOT and Visionox are expected to start mass production of Gen6 flexible OLED starting in 2018, flexible OLED shipments will likely grow at an average growth rate of 59% per annum, reaching 354 million units by 2022.
This report compares the structure and process of rigid OLED and flexible OLED, and analyzes the trends of technology development for foldable OLED implementation by layer. It also compares the flexible OLED application technology of Samsung Electronics, Apple, and LG Electronics which released mobile devices with full screen OLED. The report also forecasts the flexible OLED market from 2018 to 2022 by categorizing into various perspectives including flexible type, country and generation.
According to the report, full screen OLEDs of flexible OLEDs will ship 265 million units in 2018 with a market share of 82.1%, and 1,022 million shipments will be made in 2022, accounting for 79.5% of the market, leading the flexible OLED market. In addition, the foldable OLED, which has been receiving a great deal of attention recently, is expected to ship 5 million units from 2019 and 53 million units by 2022.
<Foldable OLED Shipment Forecast in 2018~ 2022>
With the Google’s comments in 2015 that the new IoT era is coming, the 13th China International Display Conference started with the presentation of BOE, a large Chinese display company, with the topic of the era of smart interfaces to be developed in the future.
Randy Chen (BOE, Sales Marketing Executive) shared the overall IT market trend as the first presentation and delivered the BOE’s strategy within it. At the heart of the IOT industry, which is expected to account for around $ 10 trillion in 2050, smart interfaces that link 5G communications and electronics to displays will play a big role and emphasized 8K and flexible display as BOE’s survival strategy. For this, he announced that they are working to build the 8K Industry Alliance and continuing to invest in the production of flexible displays starting with Chendu’s G6 Flexible Line. OLED panels produced in the Chendu B7 line, which began operating in the second half of this year, will be supplied to a smartphone maker in Shenzhen and expected to be seen in the market early next year.
Next, Xiuqi Huang (GVO, Vice President) of Visionox, who first started producing OLEDs starting with PMOLED, mentioned the change of smartphone trend and said that a mobile device with a foldable and rollable type using a flexible panel will be introduced in the future. He said that the technological development is required not only in design but also in related equipment and materials and Visionox has also been actively developing its technology.
CSOT, which produces QD-LCDs together with Samsung Display, mentioned the development potential of QLED and OLED TV and said that it was spurring technological development and investment as a latecomer. Especially, it was developing large-area inkjet printing technology that has advantages of relatively high material utilization rate and price competitiveness, on the other hand, it shared the goal of developing a smartphone panel that minimizes Bezel.
Following the presentation of representative panel companies in China, Lee Choong-hoon of Ubi Research, a global OLED research company, forecasted the market size of the OLED market, which is already leading the small-medium-sized panel market and the premium TV panel market and discussed why OLEDs have grown rapidly as a next-generation display. Ubi Research, as an OLED professional research company, is suggesting directions for future growth of OLED based on years of data and research experience.
In current display industry, major global smartphone makers such as Apple, Samsung and Huawei already have plans to apply OLED to all flagship models and TV companies such as LG Electronics and Sony have also shown that OLED TVs can only succeed in the premium market. This is why we expect the development of various types of panels and various applications that maximize the advantages of OLED forward.
■The OLED equipmentmarket is expected to reach $84.9 billion in 5 years.
■Korean and Chinese panel companies will take over 90% of investment in panel equipment.

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.”

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. ”

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.
In ‘18th China High- Tech Fair,’ BOE collected a big topic by exhibiting 55” UHD OLED TV of Skyworth to which 55” UHD OLED Module was applied.
CSOT also publicized 31inch curved FHD OLED panel this time even though they have exhibited 31inch FHD OLED panel in the past.
About 80inch was realized by attaching 3 Curved OLED panels, and resolution was 5760*1080 along with 150nits brightness.
Two enterprises manufactured the product together by applying WRGB+CF structure having been produced massively in LG Display.
In this exhibition, BOE and CSOT became to have first tile in Chinese enterprises with 55inch UHD OLED and 31inch curved OLED, and it is expected that it could be new drive of WRGB OLED panel market afterwards.
BOE and CSOT are manufacturing the panel for OLED TV in Gen8 pilot line of Hefei and Gen4.5 R&D line of Shenzhen, China respectively, and two enterprises are under positive consideration about large-scale OLED mass production lines.
Currently LG Display possesses mass production lines uniquely in relation with large-scale OLED panel market, and is leading OLED panel market alone. In future, BOE and CSOT are expected to join in large-size OLED panel market, and it is anticipated that market expansion through competitions in large-size OLEF panel market could be made.
