Dark clouds are approaching Korean industry by the corona virus that has been blown since the beginning of the year. Wuhan, the birthplace of the corona virus, is badly affecting the Chinese display industry because it is a key place where Chinese display makers are building large production bases.

Wuhan and other plant set-ups are experiencing difficulties due to the lack of manpower needed to build the line. At the same time, the utilization rate of the entire supply chain in China is falling sharply, as the labor force of parts and materials manufacturers in China is delayed to return to the factory. In the smartphone industry, the center of the OLED industry, iPhone production is affected in the first quarter. Foxconn’s factories, which produce iPhones in Zhangzhou and Shenzhen, China, are operating at 50% at end-February. This is because manufacturing workers are returning to the factory late. Companies such as Huawei, Xiaomi, Oppo, and Vivo are also hampering smartphone production due to delays in parts procurement.

Nevertheless, the production of OLED smartphones is not much affected yet. First, Samsung Display’s panel production plant, which accounts for 86.3% (2019) of OLED shipments for smartphones, is located in Korea, while the module plant in Vietnam is not affected by China. In addition, the supply chain has no effect as most of the material production bases that make up OLED panels (including modules) are also in Korea.

Samsung Display’s OLED production for smartphones in January and February totaled 48 million units, less than 2 million units compared to 50 million units shipped in the same period in 2019. Of these, 14 million and 17 million units were supplied to Chinese smartphone makers in 2019 and 2020, respectively. This year, more than 3 million units are shipped. So far, Samsung Display’s OLED business is not affected by the corona virus.

The total market share of Chinese OLED panel makers in 2019 is 11.7%. By February, the panel utilization rate of Chinese OLED panel makers was maintained at 80%. The impact of factory operation due to lack of manpower is about 20% because most of the display manufacturing industry is driven by automated facilities. Chinese OLED makers import most of the major materials, including light emitting materials, from Korea and Japan, so they are hardly affected by the corona virus.

The parts procurement status of smartphone makers in China affects the market. If Chinese suppliers, including Huawei, fail to procure parts in China, smartphone production will be hampered. However, as Samsung Display’s OLED production for China is progressing smoothly, Chinese smartphone makers have a strategy of maintaining OLED smartphones, which are expensive brands.

In addition, the first quarter is the off-season with the lowest shipment season, so even if it is difficult to operate a smartphone manufacturing plant until March, the impact on the overall market is about 10%. After the second quarter, if the corona virus subsides, demand can resume.

The problem is from March. China’s corona virus has slowed down, but South Korea has been expanding since the last week of February. There is someone has a virus at Samsung’s Gumi smartphone manufacturing plant. In addition, the Vietnamese authorities, concerned about the influx of South Korea’s virus, refused to visit Koreans, which may make it difficult for the headquarters to properly deal with problems with Samsung Display’s module plant management in Vietnam.

Most important of all, the corona virus is spreading all over the world, and economic activity is severely reduced. In China, the entrance of the apartment is blocked, so it is difficult to bring TV. The Chinese TV market is shrinking. Many people are refusing to go out because they are concerned about a corona virus infection, so fewer people visit a store and buy a smartphone. Consumer sentiment is falling significantly.

Assuming that the corona virus crisis will end in March in Korea and China, the impact of the smartphone OLED industry on 2020 is estimated to be about 5%, but if it is prolonged, it may be adversely affected by more than 10%. Assuming that the corona virus crisis will end in March, the impact of the smartphone OLED industry on 2020 is estimated to be around 5%, but if it continues until the first half of the year, it could be adversely affected by 10%.

The OLED business for TV is slightly different. LG Display’s factories that produce exclusive OLED panels for TVs are located in Paju, Korea, and Guangzhou, China. The Paju plant is not disrupted at all. Like OLEDs for smartphones, parts and components are mostly supplied by Korean and Japanese companies, so Paju factory is not affected by China.

The problem is the Guangzhou plant. LG Display has been expected to produce panels since September 2019, but its supply has been delayed due to poor panel lifetime. LG Display has begun production of panels again this year and is undergoing product tests from customers. Recently, however, the corona virus has begun to spread in Korea, making it difficult for Korean engineers to go to Guangzhou. Even if the corona virus disappears in the first quarter in China and the factories operate normally, it may take some time before the panel is supplied from the Guangzhou plant.

According to Ubi Research’s OLED market track, the 2020 forecast is 4.95 million units without considering the corona virus situation, of which 750,000 OLED panels for TV can be produced by LG Display in the first quarter. If the 55-inch production volume is large, up to 800,000 units can be produced. Since the data were prepared in anticipation that panels produced at the GuangZhou plant will be available from the second quarter, LG Display’s panel supply is expected to be 1.4 million units in the second quarter.

However, it is possible that production will be delayed after May if the customer’s quality certification of panels produced at Guangzhou plant is delayed due to the Korean coronavirus rather than the Chinese coronavirus. In that case, the annual TV panel production could be reduced by about 200,000 units, which is expected to decrease by 4% from the estimated total. However, if the corona virus is prolonged by June, it can cause up to 10% of adverse effects. The market should consider 500,000 fewer than expected.

Samsung Display attended the Taipei Grand Maple Hotel on November 7, attended by 350 global customers including HP, Dell, Lenovo, Asus and other major ODMs such as Compal, Quanta and Wistron. ‘Samsung OLED Forum 2019 Taipei’ was held.

Samsung Display presented OLED notebooks as a new growth engine in the stagnant IT market for global IT companies and introduced differentiated strengths that only OLED can provide.

Under the theme of ‘New Era of Laptop with OLED’, Samsung Display is a premium notebook with OLED’s thin and light design flexibility, infinite contrast ratio, DCI-P3 100% wide color gamut and color accuracy, and excellent outdoor visibility. Emphasis is placed on the essential image quality characteristics.

In addition, the company also unveiled a roadmap for fusion technology of OLED’s unique display sensors such as Fingerprint Display and Sound Display.

Samsung Display has already developed OLED for 13.3-inch and 15.6-inch notebooks in the first half of this year and has cooperated with HP, Dell, Lenovo, and Asus to supply panels to 13 kinds of notebooks. The company plans to expand its product lineup to mid-end and respond to market demand.

<15.6-inch multi-screen OLED notebook exhibited by Samsung display at IMID 2019>

LG Display announced on the 23rd that it recorded sales of 5,827.1 billion won and operating loss of 436.7 billion won in the third quarter of 2019 according to K-IFRS.

Revenue increased 9% QoQ (5.35 trillion won) due to the full-fledged sales of plastic OLED business and the expansion of mobile panel sales.

On the other hand, 3Q operating loss fell last quarter due to a sharp drop in LCD TV panel prices that exceeded market expectations, reduced utilization of related fabs, and increased depreciation expenses associated with the operation of new plastic OLED plants. The operating loss recorded 436.7 billion won.

Net loss was 442.2 billion won and EBITDA was 611.8 billion won (EBITDA margin of 10.5%).

Revenue breakdown in the third quarter of 2019 recorded 32%, a 9% QoQ decline for TV panels due to a decline in shipments due to adjustments in LCD TV fab utilization. Mobile panels recorded 28%, up 9% p QoQ, due to full-scale production of plastic OLED panels. Notebook and tablet panels accounted for 21 percent and monitor panels 18 percent.

Dong-hee Seo, Executive Vice President of LG Display CFO, said, “LG Display is innovating its business structure to reinforce its fundamental competitiveness and have a differentiated competitive edge.” In addition, the company plans to find ways to secure competitiveness from a more fundamental and long-term perspective, while at the same time strengthening its IT, commercial (auto) and auto (business) business capabilities that can differentiate in the existing LCD sector. Large OLEDs will accelerate the market trend utilizing the inherent value of products and continue to stabilize the business of plastic OLEDs for smartphones. ”

In addition, “We will communicate with the market by establishing a long-term vision centering on technologies and product lines that can quickly complete the ongoing LCD structure improvement activities and provide differentiated value.”

According to the OLED emitting material market track published by UBI Research (www.ubiresearch.com), the second quarter earnings was $ 329 million, an increase of 16.6% compared with the previous quarter’s $ 228 million, and 41.1% higher than the second quarter’s $ 233 million.

As a light emitting materials company with high sales in the second quarter, UDC accounted for 22.7% of the total market with US $ 72.7 million, with Idemitsu Kosan 12%, Merck, Dow Chemical, and Novaled more than 10%. None of the Korean emitting material companies exceeded 10% market share.

UDC’s strongest sales were due to the 6-month-long purchase of dopant material from the BOE, which anticipates it will be difficult to purchase phosphorescent dopant materials in the US-China trade dispute. The phosphorescent red host, phosphorescent green host, and p + materials all exceeded $ 30 million.

According to the analysis of the material usage, the total material usage of the second quarter was 21.3 tons, 21% more than the previous quarter, and 49% higher than the same quarter last year. The high usage of materials compared to the amount is interpreted as a result of a slight decrease in prices as Chinese panel makers use more materials.

In response to 8K LCD TV quality disputes that LG Electronics compared and exhibited at IFA2019, Samsung Electronics raised the problem of burning of OLED TVs.

At the exhibition hall, LG Electronics displayed the same screen on its NanoCell 8K LCD TV and other companies’ 8K LCD TVs, and magnified images taken by precision cameras on the same screen area, allowing 90% reproduction of CM (contrast modulation) of NanoCell TV. However, it emphasized that other companies’ 8K LCD TV is only 12%. The company did not say what kind of company it was, but LG was recently emphasized that LG Electronics disassembled Samsung’s QLED TV after IFA and talked that QD-LCD using QD sheet does not produce good image quality. Thus the other 8K can be estimated as SEC’s QLED TV.

In response, Samsung Electronics publicly reported to the press that 8K OLED TVs disappear due to image sticking.

There is a very confusing dispute for consumers who do not have expertise in picture quality. Putting the two companies together, Samsung’s 8K QLED TV and OLED TV are both less qualified products.

In reality, however, the two products seen by the IFA were among the best of all existing TVs. OLED TVs have very high contrast ratios, so even in two-dimensional flat screens, the perspective is displayed as well as three-dimensional TVs. QLED TVs have very high HDR, which are delicately expressed from bright to dark screens. Also, the two products must be TVs with the highest precision at 8K resolution.

Korean media have expressed a lot of negative views about noise marketing of Samsung and LG, but it seems that the two companies’ TVs have been developed.

In fact, when Apple criticized the Galaxy for its low resolution, Samsung Electronics has grown to the world’s best product by raising the resolution of OLED to QHD level. In addition, Samsung Electronics made a negative offensive by pointing to the burning of OLED TVs, but OLED TVs expanded the market to nearly 50% of the premium TV market of more than $ 2,000. Of course, most of the burning has been eliminated.

Therefore, Samsung Electronics is also expected to be an opportunity to grow 8K QLED TV’s image quality into the world’s best LCD TV.

The two companies have a negative fight because of their own grievances. If OLED TV market share continues to rise in the premium TV market, Samsung Electronics expressed a sense of crisis as the QLED TV market shrank by that much. If 8K QLED TVs lower prices and target the premium TV market, LG Electronics should prevent the expansion of the QLED TV market in order to accelerate the growth of the OLED TV market.

In a strategy battle in which the spear and shield alternate, the TV fight of the two companies will be a good opportunity for Korean TV to maintain the world’s best level.

Recently, due to the trade dispute between the US and China, a large portion of the budget planned by the Chinese government is flowing into the display industry while the semiconductor industry, which is one of intensive investment promotion industries, foreshadows difficulties. In the display industry, the focus is on OLED, which is a cutting-edge technology, and most of the investment is in the 6G line, a mobile product production line. This year has already been made at Visionox and Tianma on the 6G line, and BOE and CSOT will be invested further this year.

The Chinese government is actively investing in the display sector, which is relatively uncontained due to trade disputes between the United States and China, and it is reported that the mobile OLED production line as well as the large OLED line, 8.5G and 10.5G lines, are being reviewed ahead of time.

Large OLED lines are currently being mass-produced only by LG Display, and are being produced using oxide TFT and white OLED deposition. Samsung Display is also considering mass production by adding QD structures to oxide TFT and blue-based OLED deposition.

Samsung and LG are preparing to mass-produce or mass-produce by applying heat deposition method to organic materials, but Chinese OLED panel makers are oriented to mass production line of RGB Inkjet method (Solution Process OLED). However, as the investment has accelerated recently, experts are concerned about the investment of RGB inkjet method which has not been mass-proven.

This is because LG Display’s white OLED deposition method has already been mass-proven and Samsung Display is also planning to invest in the same deposition method with only the different structure. Indeed, it is necessary to see whether Chinese OLED panel makers will move beyond the second-place strategy to adopt the RGB Inkjet method or change their direction to the deposition method, a proven technology.

Solution process using inkjet OLED (sol OLED) has been developed mainly as a large OLED panel for TV, but recently began to attract attention in the monitor display market.

The evaporation method with FMM that produces OLED for smartphones has a bending phenomenon of FMM. Thus, the substrate is used by dividing into two or four. Since smartphone-sized FMMs are used by attaching 10 to 15 sheets to the mask frame, the profitability is very low due to the small number of cells in the production of 20-inch or larger monitors.

In comparison, sol OLED is a highly productive method because OLED can be manufactured from the original substrate regardless of substrate size and display size.

If the 27-inch and 32-inch OLED panels, which are mainly used as gaming monitors, are produced by the FMM method, four can be produced. But sol OLEDs do not divide the substrate, so the 27-inch can make eight, and the 32-inch can make six.

Therefore, in the future, OLED manufacturing technology is expected to be used in combination of three technologies depending on the application and size. Smartphone OLEDs are expected to be divided into FMM and evaporation methods, large OLED panel manufacturing for TVs with open mask and evaporation technology, and sol OLED technology for monitors larger than 25 inches.

There are three types of premium monitor market, LCD, RGB OLED, and sol OLED, but the premium OLED monitor market will be replaced by sol OLED. If 6G-class inkjet lines are invested in large quantities, sol OLED will become the flagship product in the mid-priced monitor market.

The solution process OLED annual report, published by UBI Research (www.ubiresearch.com), expects to create a market of $ 579 million by 2023. This amount represents 85.3% of the OLED monitor market by 2023.

LG Display OLED TV maintained sales revenue, it through conference call, stated it recorded annual sales revenue of 24.3 trillion won and 92.9 billion won operating profit in year of 2018.

LG Display despite of heightened global competition and downward panel price made an operating profit thanks to OLED TV, super large size TV and high resolution products.

Especially large size OLED TV maintained stable productivity and enlarged consumer bracket which enabled 2.9 million shipment on a yearly basis. It recorded gross profit within 5 years of product introduction which resulted in more than 20% in total sales revenue.

4th quarter 2018 revenue of LG display marked 6.95 trillion won TV panels accounts for 36%, mobile panels 28%, notebook and tablet panels 22% and 14% for monitor panels.

Operating profit recorded 279 billion won, 528% increase compared to the same quarter last year, 99% hike compared to last quarter thanks to high priced IT products, new introductions of small and medium size products and high added value products. LG Display aims to focus on OLED business reconstruction Seo Donghee CFO of the company said, “the ratio of OLED revenue was almost nothing 5years ago, now it is 30% this year and we estimate it is going to reach 50% of the total business.”

He also said “we will put in all assets to create new values focusing on OLED business.”

He replied to the question of large size QD-OLED of competitor, it will strengthen ecosystem and overall OLED industry. To the question of 8K and over 70inch large size OLED mass production, he replied that 8K technology is already secured as exhibited at CES2019 and said that large size OLED mass production will utilize the existing know-how of LCD production. In 2019, LG Display’s OLED demand outlook question suggests that demand for more than 14% of all flexible OLED smartphones is expected.

Regarding the large-area OLED and p OLED capacity in 2019, LGD said that the large-area OLED capacity will be completed at 70K per month in Paju and 60K in Q3 in Guangzhou, China and the pOLED capacity is expected to add 30K to the domestic 45K in 2020.

He announced that capex is estimated 8trillion won in 2019 and 4trillion won in 2020, a half of this year. 60% will be for large size OLED and 40% for pOLED. And he said pOLED mass production is currently concentrated on smart phone and cars. He expects good news from car pOLED by end of this year. He also targets over 3.8 million units large size OLED production this year.

5G communication technology introduced from next year can process higher image quality and large-capacity contents such as VR more rapidly, besides real-time streaming service. As the communication speed increases, the relevant contents, are expected to be released, which require high resolution and large screen with graphics detailed.

The current smart phone is getting bigger up to 6 inches, but it is not enough for 4K resolution of 5G communication age. Since 4K resolution is to be possible at 7-inch and larger displays, they might be the most suitable product for the 5G communication era. Foldable smart phones are digital convergence products that can function as smart phones and tablet PCs as the next generation mobile devices that use 7 inch or more displays but maximize portability.

Owing to foldable OLED, foldable smart phones are likely to be available. Several companies have rushed to produce various prototype foldable OLED displays at exhibitions and conferences. A few panel makers even pledged to mass-produce foldable OLED displays competitively. OLED display companies worldwide including Samsung Display have invested enormous development costs in order to preempt the next generation product market, and now foldable OLEDs are starting to appear.

Samsung Electronics, which is leading the OLED smart phone market, is planned to launch the in-folding type foldable phone for the first time in the world next year. Accordingly, Samsung Display has prepared 1.5R foldable OLED. For Samsung Electronics, which has suffered sluggish sales of the Galaxy S series, Foldable Phone is a super premium product that needs to be succeeded.

UBI Research (CEO: Yi, Choong-hoon), an OLED research institute, has published Foldable OLED Report. According to the report, the market for foldable OLED in 2019 is only US$ 480 million, but it is expected to grow to US $ 24.6 billion in 2023.

Yi said, “The rapid growth of the foldable OLED market is due to the fact that 7-inch and larger smartphones, which can support 4K resolution, become required products in the 5G communication era. Accordingly, the value of OLED panel makers will be determined by the success of foldable OLED production.”

However, foldable OLED is not a product that anyone can produce. Since foldable OLED has a more complex module structure than conventional flexible OLED, it is necessary to overcome the changes in various panel characteristics caused by folding. Especially in in-folding type foldable OLED, compensation circuit technology to overcome TFT resistance change and resilience required when folding and unfolding screen are typical technical difficulties. In order to realize this technology, the key challenges of reducing stress at the area of folding, selecting a proper substrate, determining the ideal stack structure, and optimizing the liftoff process, need to be overcome. Even when folding over 200,000 times, it is required to have reliability that there will be no abnormality on display image quality and surface.

“Foldable OLED Report” published by UBI Research analyzes the development trends of panel makers together with the development issues of major films that determine the reliability of foldable OLED.

Mr. Atsushi Ban, Vice President of Sharp presented a future strategy that combines IGZO and OLED through a keynote session at the 28th FINETECH JAPAN, held in Makuhari Messe, Japan from December 5, 2018.

Ban emphasized “The proportion of OLED in the entire display market is expected to grow even higher, and the new value of OLED is no different than flexibility.”

He said, “Sharp is also planning a variety of applications using the thin, light-weight and flexible characteristics of OLED. From the third quarter of 2018, its Taki plant has produced 4.5G backplanes and the Sakai plant is under injecting glass for OLED and module processing for 4.5G 15K quantity.”

Ban also pointed out the possibility of expanding the OLED industry through flexible OLED, commenting that Sharp’s next goal is to develop foldable OLED that combines IGZO. Sharp has pioneered a new display technology, called IGZO, which has been known for its semiconductor properties for years, but Sharp has developed a crystalline form that maximizes its benefits for greater display performance, and IGZO improves the performance of display panels in three significant ways: lower power consumption, higher resolution and special benefits for touch-sensitive displays. Ban expected that it could create new value if IGZO is combined with medium to large sized foldable OLED or rollable OLED.

Finally, Ban introduced Sharp’s IGZO development roadmap and announced that it will develop much improved IGZO.

Plane source technology, which was first developed by OLEDON in the world, has the principle of depositing the first organic material on the metal surface and evaporating it upwards to produce fine pattern of 2250 ppi, which is ultrahigh resolution. In this plane source process, three processes such as the first deposition, the plane source inversion, and the second evaporation are necessary, and the number of the high vacuum chambers is increased when the mass production is applied. The belt plane source FMM deposition technology introduced by OLEDON has a concept of carrying out the above processes at a time in one evaporation equipment. This is a continuous plane source supplying deposition technology in which the metal surface is formed in a belt shape.

Hwang added, “Using vertical plane source enables smooth deposition process for the 12th generation class area substrate for QD-OLED TV without sagging problem. Vertical belt-plane source evaporation equipment adopts the concept of depositing the substrate in a standing-up position so that the load on the framed glass chuck and the open mask is very low. Thus, easy transportation of the substrate, and uniform deposition process of thin film over a very large area in the static state are possible.” This technology is expected to be applicable not only to the 8th generation but also to the cluster type mass-production evaporator with substrate sizes more than 10 generations in the future.

<Vertical belt plane source evaporator for QD-OLED, Source: OLEDON>

Commenting finally that the company has successfully completed the material denaturation test for blue materials and the blue dopant deposition test, Hwang expected the plane source deposition technology to be applied to both small & medium sized OLED and large area OLED manufacturing in future.

On the other hand, OLEDON holds more than 30 related patents including original patents of plane source and belt plane source evaporator. Also, the company recently filed a patent related to a vertical belt plane source evaporator for mass production.

At the IMID 2018 exhibition held in COEX, Seoul from Oct. 24 to 26, Samsung Display presented various OLED products under the theme of ‘optimized OLED for 5G era’.
First, Samsung Display emphasized the advantages of OLED by introducing the transition process of full screen OLED and HDR & true black under the theme of ‘realistic multimedia’. Currently, the smartphone market is dominated by full-screen smartphones applied with OLED, and OLEDs are able to display a completely black color compared to LCDs, resulting in a clearer picture quality.

The company also introduced the next generation touch technology such as HoD (Haptic on Display; when you touch the screen, you can feel the physical vibration by hand. Thus, you can enjoy the contents realistically.), FoD (Fingerprint on Display) and SoD (Sound on Display) together with full screen technology.

In addition, the front of the booth is equipped with a space to experience the durability of the flexible OLED with a plastic cover window, so that visitors can try to hit the panel with a hammer or drop the ball. Various advantages of flexible OLED have been shown.

Moreover, OLED for VR, which implemented 1200ppi ultra-high resolution, automotive rollable display (CID) and 5.9 type transparent HUD were displayed, raising expectations for future development of display technologies.

LG Display unveiled its 8K OLED TV for the first time in Korea, which had been showcased at CES 2018 in Las Vegas earlier this year. This product is the biggest OLED TV that is currently in existence and provides 4 times clearer picture quality than UHD resolution.

Furthermore, LG Display showed the possibility of various OLED applications while the company showcased its 65-inch CSO (Crystal Sound OLED), a sound system built into the panel, and 77-inch UHD wallpaper OLED product that can be closely adhered to the wall to enhance interior effects in the living room.

Japan Electronics Show, CEATEC2018, was held at Makuhari Messe last week. CEATEC JAPAN 2018 is a global showcase for Japan’s growth strategies and vision of the future. Various Japanese companies exhibited products centered on IoT robots and AI. It is recognized that the electronics industry in Japan is gradually shifting from large hardware to small advanced parts and software industries.

In the exhibition, the core technology of smart car was introduced for self driving. Kyocera introduced cockpit technology that can anticipate and prevent various accidents that may occur in blind spots as advanced sensing technology and image processing technology to enhance the safety of automobiles.

For automotive display business, the company also exhibited advanced concept cars with clusters, CIDs, room mirror displays and side view displays.

According to Kyocera officials, room-mirror and side-view displays that show the external environment might have limitations and need to be converted into OLED displays since all of the concept car’s displays use LCDs.
When LCDs are used for room mirror display and side view display that show rapid changes while driving at high speed, the location of surrounding cars is to be expressed as being behind the actual location, which can result in an accident. In particular, LCDs with low contrast ratio are not able to accurately represent external objects at night.
OLEDs with high-speed response and high contrast ratio are expected to dominate the future automotive room mirror and side view mirror market.

The display of connected cars is getting bigger and bigger to for the convenience of providing various information. The displays used in general vehicles include the cluster, CID (center information display), RSE (rear seat entertainment), and RMD (room mirror display). In connected cars, various buttons of the center fascia are displayed, and a display is attached to the door using a camera instead of a side mirror. The Audi e-tron^®, all-new electric Sports Utility Vehicle (SUV) feature a small side-view OLED display instead of the existing side mirrors. According to Choong-Hoon Yi, CEO of UBI Research, the reason why automobile manufacturers are actively trying to use OLED displays is because OLED can be a good resolution in various aspects such as design, visibility and thickness. Since the side view camera is attached to the door, the viewing angle should be very good for the driver’s eyes. Especially in nighttime driving, black should be accurately represented on the display to make things clearer. In addition, OLEDs with fast response must be used for the mirror of car because the screen needs to be changed rapidly depending on speed of the car (if it is running at a high speed). In winter season when temperatures are low, LCDs with slow response times are not recommendable to be used.

Flexible OLEDs should also be used to mount the cockpit display on the dashboard that maximizes driver’s convenience.

<BenzのF015 cockpit displayとAudiのe-tron side view display>

In contrast, LG Display, the strongest player in the market for OLED TVs, is looking for the display market for clusters and CIDs as flexible OLED with two layers of RGB OLED. Visteon, the second-largest supplier of automotive displays, is preparing for the cluster market with LG Display’s pOLED. Since 12.3-inch p OLED is made of LTPS substrate and its OLED process is more complicated than that of OLED for smartphone, panel prices including module are expected to be equal to 55-inch WRGB OLED, which can create a premium market even if the quantity is small.

<Visteon, 12.3 inches pOLED>

According to “Automotive OLED Display Report” published by UBI Research, the market for automotive OLED displays led by Samsung Display and LG Display is expected to grow to US$ 540million in 2023.

Attentions are growing for the foldable smartphone since it can provide a wider screen and higher resolution than the display of conventional smartphones, while maintaining the portability of the smartphone. The foldable smartphone is a smartphone when folded, and it becomes a tablet PC when it is unfolded. Following Samsung Electronics, Huawei is also aiming to launch a smartphone with a foldable display this year.

Yi Choong-Hoon, president of UBI Research, said, “Ideal foldable displays require such kind of reliability that there is no problem even with more than 300,000 times folding at the bending radius of 1R or less. For this, some changes or innovations are needed in the material and structure of the display.

In the ‘2018 OLED Component & Material Report’ published by UBI Research on May 21, 2018, the key issues and development trends for foldable OLED display with a bending radius of 1R are described together with the classified contents of structural change to secure reliability at thickness reduction and alternative material development.

<Change in OLED panel thickness accoding to bending radius, 2018 OLED component & material report, UBI Research>

In addition, the report covers the application status, development trends, and market forecast of key components and materials for rigid OLED and flexible OLED for mobile device, and large-area OLED for TV. Thus, it is helpful for the related part and material companies to develop their future directions, establish business strategies, and analyze technology and market trends.
