According to the market track for the second quarter of 2020 published by UBI Research, the total OLED shipments in the second quarter were 107 million units, down 13.4% (QoQ) from 124 million units in the last quarter. In addition, it decreased by 16.6% (YoY) compared to the 122 million units in the second quarter of 2019. This is because sales of OLED set devices decreased due to the aftermath of COVID-19.

However, it was found that the OLED market for smartphones that support the OLED market was significantly affected by COVID-19 compared to the overall market.

OLED shipments for smartphones in the second quarter were 87 million units, down 17% from the previous quarter (QoQ), and 23.1% from the same quarter last year (YoY). Compared to the decline in overall OLED shipments, the decline in OLED shipments for smartphones is even greater. However, the reason for the decline in OLED shipments for smartphones is concentrated on rigid OLEDs.

Despite the sharp decline in OLED shipments for smartphones, flexible OLEDs grew 38% compared to the same quarter last year.

However, the YoY of rigid OLED shipments was -40.3%, a sharp decline from the same quarter last year.

The reason why the increase in flexible OLED for smartphones has soared and the shipments of rigid OLEDs have fallen sharply is because Chinese smartphone makers reduced production of mid-priced smartphones using rigid OLEDs and increased smartphone shipments using flexible OLEDs.

According to UBI Research’s CEO Choong Hoon YI, the reason Chinese smartphone makers have increased their flexible OLED smartphone shipments is: First, due to the influence of Apple, Chinese smartphone makers also use OLED for their flagship models. In particular, Chinese smartphone makers use the name plus or max, which are used by Apple and Samsung Electronics, for the highest-end specifications, and imitate that they are making a product that is equivalent to Apple and Samsung Electronics, which are the most recognized in the smartphone market. The second reason is that Chinese display makers have improved OLED manufacturing technology, allowing them to produce panels similar to Samsung Display’s OLED. In particular, it is because Chinese panel makers are supplying panels at 60% of Samsung Display’s price, so Chinese smartphone makers have increased the choice of flexible OLEDs. The third reason is that Chinese panel makers can supply OLEDs at low prices because of the Chinese government’s subsidy policy.

YI said that the OLED industry will become more active due to the increase in OLED usage by Chinese smartphone makers, but the growth of Samsung Display’s OLED business, which has maintained a monopoly position in the smartphone OLED market, may stop growing due to the increase in production of Chinese panel makers.

On June 18, 2020, Jiangsu Lemeng Precision Science and Technology Co., Ltd. (江苏乐萌精密科技有限公司, hereinafter Jiangsu Lemeng) invested 200 million yuan to sign a project contract to confirm the OLED metal mask. It was held in the state-of-the-art new district of Changzhou, Changzhou, Jiangsu Province.

Jiangsu Lemeng (江苏乐萌) secured 77,000 m² new plant site for expand the OLED metal mask production line. Based on the existing G6 and G5.5 Mask Frame production lines, it will expand production capacity and secure large-scale production capacity of CMM. After the project is completed, Jiangsu Lemeng (江苏乐萌) can produce 8000 Mask Frames and 1000 CMMs annually, and the production sales are expected to reach 500 million yuan. Metal masks are core consumable parts required for OLED production, and have been exclusively supplied by Japanese and Korean companies for a long time.

Jiangsu Lemeng(江苏乐萌) is a subsidiary of Lemeng, Changzhou City, invested 120 million yuan from OLED business unit of Lemeng, Changzhou City, the predecessor, and related to OLED metal mask industrialization from 2017 Technology has been developed. Started mass production of Mask Frame from October 2019 and has a production capacity of about 1000 pieces per year. Jiangsu Lemeng is known to have already secured CMM industrialization technology, and is expected to secure 1,000 CMM production capacity annually from June 2021, when the new facility is completed.

The touch panel technology installed on a mobile phone is an important element technology that performs a user interface function. Touch technology is changed from an add-on type to an on-cell type in flexible OLED displays.

The built-in method in which a touch sensor is formed on a thin film encapsulation (TFE) is called by various names such as Y-OCTA(YOUM on-cell touch AMOLED), ToE(touch on encapsulation) or FMLOC(flexible multi-layer on cell touch) for each panel maker. Unlike the add-on type, the on-cell type touch sensor is formed directly on the top of the encapsulation layer without a separate base film. Due to this, the on-cell type has a higher process difficulty than the add-on type, but it is advantageous to manufacture a thin OLED panel thickness, and there is an effect of reducing the process cost.

Recently, in order to apply this on-cell type touch technology to mobile phones using OLEDs, each display manufacturer is undergoing a step-by-step line modification work. Four mask steps are added to apply the on-cell type touch technology. There are two ways to cope with this process step increase: to install and respond to new equipment as much as the process to increase, and to proceed with the process at existing facilities.

Samsung Display decided to use an existing exposure machine to use the on-cell type touch technology in the existing A3 line (Tangjeong), and is in the process of remodeling the 105K capacity TFT production line. In the existing process flow, a back plane process is performed with mother glass of 1500×1800 mm2 and 1500×900 mm2 glass with half-cutting of this mother glass is processed in the OLED process. Therefore, in order to process the half-cut glass again in the back plane equipment, the jig manufacturing method of connecting and processing two cut sheets is applied. After this modification, the production capacity of the A3 line will be reduced. The amount of 105K of the A3 line that is currently being renovated is changed from LTPS process to LTPO process, and it is combined with Y-OCTA process. In this case, 3 mask steps increase as LTPS is changed to LTPO, and 4 additional mask steps increase for Y-OCTA. As a result of the total increase of 7 mask steps, the A3 line is expected to reduce the existing 105K production capacity to approximately 75K level after remodeling.

China’s BOE is also constructing built-in touch processes in B7 and B11. BOE is in the process of adding and processing exposure equipment, etc. as a way to add a built-in touch process. In this case, there will be no significant change in production capa.

According to UBI Research’s report on changes in the OLED market caused by coronavirus, the forecast for the 2020 OLED modification market is $ 36.7 billion in sales and 612 million units. This is a decrease of 4.8% and 7.6%, respectively, from the expected sales of $ 38.5 billion and shipments of 6.6 million units at the beginning of the year.

As a result of UBI Research’s analysis of the effect of coronavirus on the OLED market for two months, the global smartphone market is expected to drop by 20% and the TV market is expected to decrease by 15%. However, the impact on the overall OLED industry was judged to be only 5-8%. OLED panels for smartphones, TVs and watches are expected to decrease, but the market for OLEDs for monitors is expected to increase.

The expected OLED shipment for smartphones was 527 million units at the beginning of the year, but the forecast for correction is 486 million units, a decrease of only 7.8%. Although the market for Galaxy and iPhone is analyzed to be higher than the average decrease rate, Chinese smartphone makers are expected to reduce LCD smartphones and increase production of OLED smartphones significantly.

Chinese smartphone makers’ use of OLED seems to follow Apple’s business direction. Flagship models of Chinese smartphone makers have used Pro and Pro Plus. Pro is the model grade name used by Apple and Plus is the model grade name used by Samsung. However, flagship models of Chinese smartphone makers that are launching this year are using both Pro and Pro Max as well as Apple. All of these models, like Apple, plan to use flexible OLEDs.

The OLED TV market was found to be greatly affected by coronavirus. Estimated shipments at the beginning of the year were 4.9 million units, but the forecast for correction was 3.6 million units, down by 1.3 million units. A 26.5% reduction is expected. This is 300,000 units more than 2019 shipments. This is because the production schedule of the Guangzhou factory has been postponed since the third quarter due to the coronavirus, and TV sales are plunging due to the spread of coronavirus in Japan and Europe, the main markets for OLED TV. In fact, Japan’s TV performance in the second quarter was below 50% in 2019.

However, the demand for the OLED panel business for monitors that Samsung Display has been promoting since the second half of last year is expected to increase due to the game industry, telecommuting, telemedicine, and remote classes due to the aftermath of the coronavirus.

UBI Research(www.ubiresearch.com), a company specializing in OLED market research, predicted that the market for OLED emitting materials for 2020 will rapidly grow to $ 1.9 billion.

According to the OLED emitting material market track published by UBI Research every quarter, the emitting material market in 2019 was $ 1.304 billion, up 39.2% from 2018’s $ 0.937 billion market.

The reason for the growth of the emitting market in 2019 is proportional to the growth of the OLED panel market for smartphones. This is because OLED shipments for smartphones in 2018 were 407 million units, but growth was 16% in 2019 at 474 million units. (Source: UBI Research 2020 OLED Display Market Track).

The reason why the emitting material market growth is greater than that of the panel market is that 6G flexible OLED factories of Chinese panel makers have started operation. The production amount is still small, but the yield is low, so the input of the substrate is twice the amount of production, so the consumption of emitting materials is very high. In addition, it is one of the reasons that the market for emitting materials has grown due to the small purchase volume compared to Samsung Display.

As a result of counting sales by emitting materials companies in 2019, UDC accounted for $ 233 million, accounting for 17.9% of total sales, and Samsung SDI accounted for $ 212 million (including Novaled sales), accounting for 16.2%.

In 2020, both panel makers’ capacity and utilization rate are expected to increase, and consumption of emitting materials is also expected to increase.

The total consumption of emitting materials in 2019 was 73 tons, but it is expected to increase to 102 tons in 2020.

Expected consumption for each material is 16.9 tons for HITL materials and 4.15 tons for blue host materials. Blue host and dopant materials are expected to increase rapidly from 2021 when Samsung Display starts mass production of QD-OLED.

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.

According to UBI Research’s 4th quarter OLED display market track, rigid OLED is still the main product in the OLED market for smartphones, with 79.2% of the total OLED market in 2019. As a result of counting and analyzing shipments up to the third quarter of 2019, rigid OLED accounted for 237 million units of the total shipment of 338 million units.

<Source: UBI Research Q4 OLED Market Track>

Display companies all over the world have invested heavily in the flexible OLED line, but rigid OLED is still the main OLED used in smartphones. This reflects that the display companies have invested without forecasting the market situation properly.

Rigid OLEDs for smartphones are mostly supplied by Samsung Display. Rigid OLEDs are also produced in China’s Visionox and EDO, but are not yet available to brand companies. As the A1 and A2 lines, which produce rigid OLEDs at Samsung Display, are both in full operation, Samsung Display can no longer supply products in the growing rigid OLED market.

Flexible OLED lines will continue to be invested by 2023, and the annual production area will increase to 20 million square meters per year, but the line capa for rigid OLEDs has been frozen since 7 million square meters per year.

<Source: UBI Research Q4 OLED Market Track>

Therefore, in order to cope with the growing rigid OLED market, it is necessary to convert flexible lines to rigid OLED lines or to further invest in rigid OLED lines.

In order for Samsung Display to dominate and have a differentiated market in the display industry, it is time for latecomers to consider converting flexible OLED lines to rigid OLED lines.

In October 2018, Samsung Display received a lot of attention by supplying OLED for side mirror replacement to e-Tron of Audi, a global automaker. e-Tron has a camera installed in the side of the existing side mirror, and the driver can check the surroundings through the OLED installed in the vehicle.

Mirrorless cars were discussed at the SID Vehicle Display 2019 panel discussion in September 2019.

Drew Harbach pointed out that “existing side mirrors may have the effect of glare in tunnel-like spaces.” “The cameras and displays can be reduced to provide a better night view.”

He mentioned that the resolution of the display is important, of course, but the contrast and FOV are also very important factors. He also emphasized that the contrast ratio should be very high so that objects can be seen under any environmental conditions.

The high contrast ratio is a very helpful factor in recognizing objects not only in dark nights but also under the strong sunlight of the day.

Panelists mentioned the various displays such as LCD, OLED, micro LED, etc., but OLED is the only display with high contrast ratio and wide viewing angle in the environment where mass production is possible. In addition, OLED has a very fast response time, which is widely used in VR devices and professional monitors where image quality is very important.

OLEDs are mentioned as potential candidates for side-mirror displays and are expected to be used in internal displays, such as clusters and CIDs (center information displays). Korean and Chinese panel makers are actively developing automotive OLEDs, and Samsung Display has forecast that automotive OLED panels will increase to about 3 million by 2022.

According to the OLED market track published by UBI Research in the third quarter, OLED sales increased to $ 6.9 billion in the second quarter. This is an increase of 9.5% compared to last quarter, an increase of 18.5% from the same quarter last year.

The biggest reason for the increase in sales is the increase in OLED sales to China by Samsung Display, which leads the OLED industry. Huawei, Oppo, Vivo, and Xiomi’s OLED usage increased more than 1.5 times compared to last year, and Samsung Display’s sales in the second quarter were $ 5.5 billion. In addition, LG Display’s WRGB OLED sales growth and BOE’s flexible OLED sales boosted the market to $ 6.9 billion.

Samsung Display’s sales share accounted for 79.9% and BOE’s market share increased to 6%.

<Source: 3Q2019 UBI Research OLED Market Track>

In 3Q, sales are expected to increase further. Samsung Display’s flexible OLED shipments will increase further for Apple’s new models and Huawei’s Mate. LG Display will also begin supplying flexible OLEDs to Apple, and BOE has decided to supply flexible OLEDs to LG Electronics.

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.

Japan, which used to be the strongest country in display industry in the past, gradually declined through the era of CRT, PDP and LCD, and has fallen to the third-largest producer in OLED industry after China.
Currently, Japanese companies that produce AMOLEDs are Sony and JOLED. Both companies are producing OLED for special monitors at 500 ~ 1,000 units per month. Although JDI has developed flexile OLED, it has not commercialized yet.

Sharp has challenged the OLED market for smartphones in the current Japanese manufacturing environment, which was passive in production. The production of flexible OLED is to be started at the 4.5 generation production equipment of Sakai plant. The flexible OLED is scheduled to be adopted on AQUOS zero model for Soft Bank.

The product was exhibited at the Sharp booth of CEATEC 2018, which is a QHD+ 6.2-inch dual edge type. Sharp
Officials said that the sales have not started yet.

In addition, Sharp also exhibited two types of flexible OLEDs which are under development.

According to the 3Q AMOLED Market Track issued by UBI Research, the second quarter OLED market was sluggish, affected by the lower utilization rate of Samsung Display. However, in the third quarter, the market rebounded rapidly, forming a market of US$ 8.3 billion.
The performance of the third quarter is up 43.9% from the US$ 5.77 billion in the second quarter, and up 16.6% from the same period of last year.

Samsung Display, which drove sales growth, posted sales of US$ 7 billion, while OLED sales for Smartphone accounted for US $ 7.2 billion as its major application.
By country, Korea achieved sales of US$ 7.9 billion, accounting for 95.5% of the total market. China occupied 4.3% of total sales with US $ 360 million.
Yi Choong-hoon, CEO of UBI Research, explained that 3Q sales growth was attributable to Samsung Display’s production of Galaxy Note and Flexible OLED for Apple’s iPhone XS.

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.
