(Full text of articles: http://news.donga.com/3/all/20190421/95157197/1)

The Chinese companies’ volume offensive raised concerns that the OLED industry, following liquid crystal displays, could face oversupply problems. Analysts say that while South Korean display manufacturers’ performance in the first quarter has deteriorated due to a sharp drop in prices of LCD panels, even OLEDs, which are seen as new growth engines, could be on the verge of oversupply in the near future.

According to a recent report released by Hana Financial Management Research Institute on Monday, the production capacity of OLED plants currently being built by Chinese companies such as BOE, CSOT and TCL is twice that of South Korea.

Retirement of OLED business for general lighting… Accelerate selection and focus of ‘New LG’ (The Korea Economic Daily)

(Full text of articles: https://www.hankyung.com/economy/article/2019042211521)

LG Group is speeding up efforts to reorganize its business portfolio for future growth. LG Display’s decision to withdraw from its organic light-emitting diode (OLED) business for general lighting is part of its objection. The “choice and focus” strategy has become a keyword that penetrates LG Group Chairman Kwang-mo Koo “New LG,” who headed the group last year.

According to LG Group and others on the 22nd, LG Display has given up its OLED business for lighting that it has been pushing as a new growth engine. It has been about a year and six months since it started mass-producing products from new OLED production lines.

It is heard that LG Display has decided to withdraw from markets by gradually reducing mass production of OLEDs for lighting that are produced at 5th generation OLED lines (P5) in Gumi, North Gyeongsang Province. Instead, it has decided to focus on OLED markets for vehicles that have huge growth potential and can produce synergy with the group’s automotive electric field (electric and electronic devices) business. LG’s acquisition of ZKW, which is a global automotive headlamp manufacturer, also affected LG’s ability to provide lighting for vehicles.

LG Display entered the general lighting market by introducing a new brand called ‘Luplex’ at the end of 2017. However, it is rumored that it has decided to give up its business after losing out on price competition from current LED (light emitting diode) lighting companies.

Softly bending OLED lighting like a paper, Development of Roll-to-Roll manufacturing technology

March 31, 2017/in /by olednet

Korea Institute of Machinery and Materials (KIMM hereafter, Cheon-Hong Park, the president of KIMM), the Ministry of Science, ICT and Future Planning-affiliated developed the 300mm grade of Roll-to-Roll manufacturing technology that allows to produce flexible OLED* by simple process with GJM Co., Ltd (Mun-Yong Lee, CEO) for the first time in Korea.

The Printed electronics research laboratory of advanced production equipment research center in KIMM succeeded in applying traditional Roll-to-Roll printed electronics technology to the OLED production process. Using Roll-to-Roll vacuum evaporation equipment, it is possible to produce flexible OLED products inside a single chamber as evaporating OLED light emitting organic layer and metallic electrode to roll type film in order. Available OLED products consist of many organic, inorganic layers of 1~hundreds nanometer (nm) level of thin and each layers are manufactured through vacuum thermal evaporation process.

Producing the flexible OLED display must go through complicated processes until now. The method that has been used so far is that attaching a film on the glass plate and passing it over the evaporation process to produce OLED, and then separating a film from the plate. The one-side curved display of smart phone screen which was launched by Korea conglomerate was made in the same manner of process which is attaching a film on a glass plate or coating and then circulating evaporation equipment to produce OLED and separating OLED from the glass plate. There were demerits of the need for adding additional process of attaching and detaching a film as well as for various additional evaporation equipment upon necessary steps.

Applying the currently developed technology, it is possible to produce OLED with ‘multi-layer evaporation’ process that evaporates organic layer and inorganic layer sequentially on top of a film after letting a roll type film which is rolled inside a vacuum chamber flow. The time and facilities required for production are greatly reduced, therefore, not only large companies but also small and medium-sized enterprises can produce flexible OLED.

This OLED producing method is expected to be used in the lighting industry first since it can be produced by surface unit unlike point unit of the existing LED, and be possibly made in any desired shape due to its flexibility.

Shin Kwon, senior researcher of KIMM explained “With Roll-to-Roll vacuum evaporation equipment, it can be used for continuous production of flexible OLED which is notable display for the next generation. Especially in the display industry, it is a key technology to secure the technology gap feasible to contribute to gain supremacy over China from its rapid pursuit while Korean R&D is stagnant.

Also added “we are under development of fine pattern mask align technology which allows to produce individual pixels Red/Green/Blue used in actual display product. When it’s completed, it can be applied to the high resolution display and is a strong technology differentiated from Fraunhofer in Germany and Konica Minolta in Japan developing similar technologies.

This task was conducted for the leading study sponsored by the ACE*** program which is a technical business support program of KIMM, and has been conducting with GJM Co., Ltd. with a support of the economic cooperation business of the Ministry of Trade, Industry and Energy since Oct. 2015. GJM Co., Ltd. as a hidden champion holding core technology in OLED, recently made a delivery performance in Taiwan, Japan, and China and is pushing ahead with full-scale equipment commercialization.

OLED enabling various styling and designs is perfect to lighting for automobiles

October 25, 2016/in Focus on /by olednet

Applications of various lighting such as LED and OLED etc. have been expanded so as to implement unique designs and diversified functions of own brand by each automotive company as well as developments of automotive industry including smart-car and connected-car etc. are being made at the same time. In this regard, Center Head Ju Jae-young of Korea Photonics Technology Institute stated current situation by saying “Lighting for vehicles belongs to the business which expects profitability, but it is not easy for late starters to break in because entry barrier is high from characteristics of automotive industry. Ultimately, whether to stimulate purchase desires is important.” Also, he counted ‘styling possibilities’ as one of successful LED lighting by saying “The reason of getting more popularity of LED than existing halogen and HID is derived from the fact that LED has strong points in designs.”

And then, the Head forecasted like “The exterior deco of lamp market for automobiles overtook the interior deco market from the start of 2013, and 3.1B USB market will be made in 2019 by achieving annual 11.6% growth in average to 2019 from 2014,” and said “The exterior deco market will grow up over 15% annually, and DRL (Daytime Running Lamp) and Head lamp are leading market due to their high growth rates.”

Besides, Center Head Ju Jae-young stated “In order to enter market by OLED, it has to stimulate purchase desires with new designs which do not substitute LED simply,” and added “There are possibilities if designs are unique, and stimulate sensitivity like Fun- VII concept car of Toyota or lighting of Chrysler having been disclosed to the public in 2013.”

Like this, OLED is thin, light and can be bended characteristically, and has strong points such like free designs are available, so it is getting a lot of interests as next-generation illuminants including indoor lighting etc. as well as lighting for vehicles. According to 2016 OLED lighting annual report having been published in August 2016 by UBi RESEARCH, it explains that OLED lighting is known to display same performance with LED in R&D levels regarding characteristics of brightness and lifetime etc. as eco-friendly lighting and having high energy-efficiency, thus OLED seems to have sufficient competitiveness only if requested brightness is satisfied along with each automotive company.

OLED Technology, extend the field from automobiles to airline industry.

September 20, 2016/in /by olednet

It is expected that we may be able to meet flights with OLED technology soon.

In existing OLED market, display is applied in mobile field and lighting is applied in indoor lighting field, and it was known several companies seem to be proceeding projects to apply it at either rear lamp or dash board area of the automobile.

However, in IFA 2016 held in Berlin Germany, LG vice president of HE Bongseok Kwon had reporter meeting where he said “we are currently in negotiation with two global airlines to install OLED display at front monitor and window, and the period of application must be discussed for not only seats but also including all parts such as windows.

Especially, several companies including Lumiotech, OSRAM, and LG Inotech already introduced technologies for applying OLED in indoor purposes as well as other fields, and third panel companies are known to be developing technologies for engrafting airline industry, so there is much attention of the outcome of new application.

OLED is designed with thin and light characteristics as well as flexibility where it is good at utilizing space without taking up large volume. Due to its characteristics, the installation is easy without location or space restrictions. So if OLED is applied in window then the flight crew can control the light penetration without having to check the window, and also people will be able to check the flight information they desire through display, and diversify the size and shape of the main display and dashboard.

Aside from these visual effect, it is expected to lower the fuel usage by decreasing the total weight of the flight. According to the contents presented in UK governmental emerging institution CPI (Centre for Process Innovation) in 2014, the fixed fuel usage is expected to decrease by applying OLED due to decreased weight of the flight fuselage and fuel, and the fuel consumed by air-conditioning can also be reduced due to low power consumption and heat, as well as the exhaustion of greenhouse gas is expected to be minimized.

Along with this, OLED related application and its industry is expected to develop continuously. According to 2016 OLED Display Annual Report published by the market research company Ubi industry research, AMOLED market is expected to be worth 14,800 million USD in 2016, and approximately 71,705 million USD in 2020 where the average yearly growth of about 49%. Also, starting from 2019 where companies’ investments actually begin, the profit for OLED lighting will also largely increase which it is expected to reach above 7,500 million USD by 2025. Therefore, it is expected to see various types of applications with OLED display or lighting in the near future.

[Expert Talk] OLEDWorks’ Co-founder David DeJoy Talks New Lighting Experience

November 16, 2015/0 Comments/in /by OLEDNET

Through an interview with OLEDNET and his presentation during the OLEDs World Summit (October 27-29), OLEDWorks’ co-founder, chairman and CEO David DeJoy discussed OLEDWorks’ vision and OLED lighting.

OLEDWorks hit the headlines in April this year when it was announced they would acquire key OLED assets and relevant intellectual property from Royal Philips whose main OLED product is Lumiblade. This acquisition was finalized earlier this month, taking this relatively small but already dynamic player within the OLED lighting industry to another level with plans that include continuing production in both Germany and the US, and expanding the product portfolio.

As the world’s first area light source, OLED lighting is naturally diffusive. As the light is uniform without flickers, the glare and eye fatigue is minimized. Although it is similar to LED in that it is a solid-state lighting, OLED produces little heat and color temperature can be easily adjusted. With its thinness of the panel and no need for extra installation space, OLED lighting can bring forth new design perspectives and applications. During his talk, DeJoy commented that OLED will bring the light closer to the user and will deliver a better light experience in diverse settings including patient rooms, recovery rooms in hospitals, retail, and museums.

Although customer response to OLED light quality is extremely positive, DeJoy acknowledged that it is facing many challenges in entering the lighting market and divided the strategy to overcome this into “the four ‘A’s”: awareness, adaptability, availability, and affordability.

The ‘awareness’ includes education about the technology and benefits, as well as confidence in the OLED lighting technology reliability. The effort to build the OLED lighting awareness includes government partnerships such as DOE Funded Gateway Projects, and NYSERDA Demonstration Projects. Designers and architects are also increasingly turning to OLED for inspiration and source material. OLED lighting’s previously mentioned advantages are closely linked to the second ‘A’, ‘adaptability’. Its thinness, lack of heat, and no need for additional installation space mean that OLED lighting can easily be integrated into fixtures and used as a building material by being directly mounted on surfaces. On the subject of ‘availability’, DeJoy emphasized that more luminaire and final products should become more available to specifiers. He added that there are many in product development but they need to get into the hands of the end user. Discussing the ‘affordability’ of OLED lighting, DeJoy used OLED panel cost scenario published by the US Department of Energy which estimates that the panel price will continue to fall to reach US$10/klm, which corresponds to approximately US$100/m², in 2025. DeJoy added that when examining the affordability of OLED lighting, the total cost has to be considered. For example, OLED lighting does not require heat sink or extra installation cost. Also, many applications do not need very high lumen output with focused beams; “it is not all about $/klm”.

DeJoy explained that OLEDWorks long term goal is making OLED lighting adaptable and available, making it easier to change the lighting when it is broken, and be user friendly. He reported that OLEDWorks will continue to expand the product portfolio, which now includes Lumiblade, for “increased performance, additional form factors, and additional CCT options, while reducing product costs”. DeJoy also added that this is “akin to the LED evolution and consistent with the U.S. Department of Energy forecast”. With their proactive and enthusiastic approach to the OLED lighting market, the industry is watching OLEDWorks with great interest. OLEDWorks’ effect on OLED lighting market is expected to be significant.

Mitsubishi Chemical and Pioneer Develops Bluelight-less OLED Lighting

August 31, 2015/0 Comments/in /by OLEDNET

Japan’s Mitsubishi Chemical and Pioneer announced their success in developing the first bluelight-less OLED lighting module. The two companies produced this module through a wet coating process for the light-emitting layer and began shipping samples on August 1.

The new OLED lighting module does not use blue emitting materials in the OLED panel and the light from the panel contains a minimal portion of blue light. According to the companies, this is less than 1% of the amount in the 3000K-type OLED lighting module developed by Mitsubishi Chemical and Pioneer.

The panel is a candle-color type with a 1900K color temperature; this is suitable for storage lighting of light-sensitive items such as cultural heritage and paintings, as well as lighting for bedrooms and medical practices.

Blue light, which has a wavelength of between 380 and 495 nanometers, has the highest energy among visible light. This is enough to reach the retina at almost full strength. This can cause eye fatigue as well as reduction in quality sleep.

With the increase of smartphone and PC use, the amount of time exposed to blue light is also increasing. Therefore, as the interest in eye health rises, this bluelight-less OLED lighting module development is worthy of attention.

[Lighting Fair Japan 2015] LG Chem, 100lm/W OLED Lighting Panel Mass Production Possible in April 2015

March 10, 2015/0 Comments/in /by OLEDNET

LG Chem estimates mass production of highly efficient 100lm/W OLED lighting panel in April this year. In Lighting Fair Japan 2015 (March 3 – 6) LG Chem announced that they have achieved 2014 target of 100lm/W development, and that mass production will be possible from April 2015. Additionally, they presented the 140ml/W roadmap until 2017, and LG Chem is forecast to keep on leading the OLED lighting market.

Until now OLED lighting had lower efficiency compared to the existing fluorescent light (approx. 100lm/W) and LED (approx. 100lm/W or higher), and was mostly used as luminaire rather than down light. However, if active mass production of 100lm/W products begins, utilization as down light will also be possible.

In this exhibition, LG Chem showcased solution concept of down light, and not a luminaire focused exhibition. They also demonstrated OLED lighting’s competitiveness as down light by securing lifetime of 40 thousand hours. This is approximately twice as long as fluorescent light and rivals LED. The biggest issue for OLED lighting is the cost. If the price becomes competitive through active investment, it is analyzed that the OLED lighting market will grow rapidly.

According to UBI Research’s OLED Lighting Annual Report 2014, OLED lighting market is forecast to grow by 100% of compound annual growth rate and form US$ 4,700 million market in 2020.
