Due to the oversupply of LCD panel in global display market, the opinion that Samsung Display and LG Display will also not be able to avoid large amount of deficit is becoming stronger.

 

As of March 28, according to market experts including securities industry, Samsung Display and LG display will both face sizable deficit in LCD sector this quarter.

 

For Samsung Display, Q1 LCD sector is expected to record up to 900,000 million KRW. The company is estimated to reduce the overall display industry deficit with the OLED profit of approximately 400,000 million – 500,000 million KRW. Consequently, Samsung Display is to record approximately 400,000 million – 500,000 million KRW of deficit in Q1 2016.

 

LG Display, whose over 90% of the current production line is for LCD, is estimated to be hit more directly. LG Display has been showing profit in LCD until 2015, but is expected to turn to deficit in Q1 2016. LG Display has been showing deficit in OLED, and market experts are also expecting more deficit in Q1 2016.

 

◆ Unlike Samsung and LG’s High Quality, China Floods Cheaper LCD

The main reasons that display industry is having difficulty include oversupply of Chinese LCD, and overall market depression. Chinese companies’ affordable LCD supply, backed by active support of Chinese government, is damaging Korean companies.

 

Particularly, companies such as BOE, which greatly improved productivity with much assistance from Chinese government including corporate tax exemption, have been pressuring Samsung, LG, and others in the global LCD market. As the Chinese companies are still aggressively investing in LCD facilities, the LCD oversupply is analyzed to continue until 2018.

 

Accordingly, the majority of the industry believe that both Samsung Display and LG Display will carry out LCD production line restructuring. In a recent conference hosted by information company IHS, senior analyst Jeong Du Kang revealed that LG Display could restructure Gumi’s P2, 3, 4 production lines, and added that some thinks L6 production could stop following the same of L5 production line last year.

 

As expected, both companies do not officially comment on these forecast. However, most of the industry players believe that the production line changes of the 2 companies are inevitable.

 

One display expert explained that “unlike Samsung and LG which do not accept even small faults, Chinese companies are pouring out products with slightly lesser quality armed with lower price, and will dominate the mainstream market”.

 

He also estimated that as Samsung and LG are nearing the situation where they have to give up LCD, the speed of which OLED will settle as the main player within the global display market will increase.

Samsung, Even if OLED TV is Released, Different from LG

<LG Elec. is Introducing OLED TV in CES 2016>

 

Within the TV market, there is an opinion that even Samsung Electronics which believes it is not yet the time for OLED panel cannot continue to insist on LCD. Experts estimate that even if it is the same OLED TV, Samsung Elec. will differentiate the actualization method from competitors’ including LG Electronics. One of the possibilities suggested is Samsung’s selection of ink-jet printed OLED TV panel.

 

Hyun-Suk Kim, Samsung Elec. Visual Display department’s vice president, who recently announced new LCD based SUHD TV mentioned that OLED TV is premature and also needs technological improvements.

 

However, it looks to be difficult for Samsung to insist on LCD TV only in the long term. China is threatening Korean companies in LCD panel market with superior price competitiveness; there is too much risk for Korean display companies such as Samsung Display to invest further in LCD production line. Although Samsung Elec. is not receiving panel supply exclusively from Samsung Display, Samsung Display is the biggest supplier. Therefore, Samsung Display’s LCD investment reduction is also expected to affect Samsung Elec.’s TV business.

 

Furthermore, Samsung Elec. is in the position of having to emphasize OLED’s superior picture quality over LCD in smartphone business, but highlight the opposite in TV. This is also an issue that needs to be tackled.

 

Despite these issues, Samsung cannot easily start on OLED TV as several problems such as price competitiveness have not been solved.

◆ Ink-jet Printing, Can it Solve OLED for TV Price Issue?

 

According to Dong-won Kim, analyst with Hyundai Securities, Samsung Display, with Samsung Elec. as the biggest client, has unfavorable structure for reducing production cost as 65 inch OLED TV panel production efficiency is low in Gen8 line.

 

Kim estimated that Samsung Display will apply solution process ink-jet printing technology to OLED TV with 2018 mass production target in order to solve this problem.

 

When producing OLED TV panel, WRGB OLED method, which uses evaporation method, can only reduce production cost by certain amount as the material usage efficiency is low. On the other hand, ink-jet printing RGB technology finely deposits ink in liquid form and can reduce materials cost. Additionally, RGB OLED has fewer organic layers compared to WRGB OLED and processes can be decreased.

 

For these reasons, some believe that Samsung will select ink-jet printing method rather than evaporation for OLED TV in future. There is also a view that LG Display, which is currently using evaporation method, will also actively consider producing ink-jet printed OLED TV panel in the long term.

 

A display expert explained that although ink-jet printing processes are simpler than evaporation method, that does not necessarily mean materials cost is always cheaper. The ink-jet printing technology is not yet perfect, and particularly for blue the efficiency issue has not yet been solved.

 

He added that Samsung Elec. has strong tendency to differentiate itself from competitors such as LG, and even if Samsung Elec. releases OLED TV, it is likely that ink-jet printing, which is different from LG, will be the preferred method.

Why is ‘Cadmium-free’ Significant? Samsung’s Quantum Dot SUHD TV

On the subject of Samsung Electronics’ 2nd generation quantum dot display equipped SUHD TV product, recently released in Korea, display experts consider the actualization of 1,000 nit without cadmium as the key strength.

 

In 2015, Samsung Elec. first launched quantum dot SUHD TV under the name nanocrystal technology. Each quantum dot of nanosize, 10,000 times narrower than a human hair, actualizes accurate color.

 

According to Samsung Elec., the 2nd generation quantum dot technology to produce this new product, an improvement over last year’s. The company emphasized that compared to the previous product, the price was reduced and brightness was improved. HDR (high dynamic range) with 1,000 nit maximum was applied to the new product.

 

The 1,000 nit brightness is the standard figure of premium image produced in Hollywood, US. If this figure is high, screen’s bright and dark areas can be experienced fully even in bright environment such as a living room area.

 

Although not applied to all models of Samsung’s 1st generation quantum dot SUHD TV, 1,000 nit brightness was applied to the majority of the models; that 1,000 nit brightness was applied to the new product is not worth much attention by itself.

◆Hazardous Heavy Metal Cadmium, Why Difficult to Remove?

 

Quantum dot film includes cadmium. As cadmium is a hazardous heavy metal, cadmium including quantum dot film cannot be environmentally friendly. Cadmium use in Europe is limited.

 

However, without cadmium, the quantum dot film’s optical efficiency is reduced. In order to make up for this, LED chips have to be applied which increases the price as well as the energy consumption. An alternative method to avoid this is development of additional quantum dot materials that increase efficiency.

 

For these reasons, some Chinese companies that produce quantum dot display equipped products select to use cadmium, overlooking the environmental issues. Samsung Elec. also emphasized that it is the only company that utilizes environmentally friendly cadmium-free quantum dot materials.

 

Through quantum dot materials’ efficiency and color mapping algorithm improvement, Samsung actualized 1,000 nit brightness without resorting to cadmium and without increase in power consumption. Color accuracy, which is a quantum dot display trait, was also improved by 25%.

 

Samsung Elec. is planning to release 14 models of SUHD TV, from 49 inch to 88 inch, in Korea. This is over 30% increase compared to last year. The price also was reduced by 900,000 KRW compared to the previous version. The new products, depending on the specifications, cost around 6 million KRW for 65 inch, and 4 million KRW for 55 inch.

A comment from a display expert is, “the new product has 1,000 nit brightness is not significant by itself, and color accuracy improvement also is not of much attention as it is an existing quantum dot trait”. However, he also put another comment from his analysis, “1,000 nit brightness was actualized without using cadmium and without decreasing energy efficiency is worth noting”.

[2nd OLED KOREA Conference] Samsung Display, Future Display’s Virtue is Design Freedom

Insun Hwang, Samsung Display’s principal engineer of the Frontier Technology Team, announced that as the display market is expanding, the key factor for positive outlook for future display is ‘design freedom’.

 

At the 2nd OLED KOREA Conference (Feb 24-25) hosted by UBI Research, Hwang gave a keynote presentation.

 

During the presentation, Hwang announced that the mobile overtook TV as the medium that people use to access daily media. According to the presentation materials, the mobile usage is increasing each year, while the TV usage is decreasing. Also as the mobile usage of people under 50 is higher than that of TV, Hwang forecast that the number of people using mobile to access information will increase. He added that if the display panel price falls down, the number of the display panels will become higher than the number of users and forecast positive future for the display market.

 

Hwang particularly mentioned that AMOLED applied products will increase as it emits less harmful blue light and is human friendly, giving smartwatch and VR as the current examples. He estimated that the smartwatch market can expand through differentiated strategy with new functions and designs. Additionally, as an issue that needs to be solved, he mentioned that the resolution of VR falls as the distance between the user and display is short. High resolution is the key in VR, and Hwang explained that approximately 2,000 ppi is required for suitable realism. He also forecast that the automotive display will lead the display field and the future market. He further explained that as OLED can actualize the curvature and transparency, it is appropriate for automotive display.

 

However, Hwang also mentioned OLED’s lack in technology. Pointing out that technology for plastic window, flexible touch, encapsulation, and backplane falls short of what the market requires for flexible display and design freedom, Hwang described the need for OLED technology development.

 

Hwang estimated many flexible display equipped smart products in future, and concluded that display’s design freedom will be the most important issue.

OLED Frontier Forum’s 3rd Section Panel Discussion Summary

The 3rd section of the 1st OLED Frontier Forum (Jan 28), OLED’s Future, held a panel discussion with government, industry, and academia experts discussing OLED industry development strategy, such as next generation technology development, convergent areas, and personnel training, and future forecast. OLEDNET summarized the answers that each expert gave to the questions of the panel chair (Professor Changhee Lee, Seoul National University).

 

Jun-hyung Souk (Professor, Sungkyunkwan University)

For SDC mobile, as the OLED depreciation is ending the OLED production cost is becoming almost the same as LCD. If OLED related experts stay within Korean industry as well as the technology, Korea can continue to lead for 4-5 years. In order to achieve the continued leadership, differentiation through flexible R2R has to be carried out, as well as the materials and encapsulation technology development.

 

 

Sung-Chul Kim (CTO, SDC)

As a-Si is an existing technology, there is no room for further advancement. Sharp’s difficulty in panel business is due to lack of technology research on the panel. Because one technology can only be used for approximately 7 months, diverse technology development is required.

 

 

In-byeong Kang (CTO, LGD)

Fast organizations cannot but win. Therefore, rapid change to OLED from LCD is needed. As difficult is the technology, cooperation between academia and industry is needed. Now is the time when this cooperation for next generation technology development is more in demand. LGD is putting in much effort for OLED profitability.

 

 

Sung-Jin Kim (Vice President, Toray Advanced Materials Korea)

Cooperation between materials and manufacturing equipment companies is important in solution process materials development. Particularly, how to control dry process is an important issue. Also, Kim expects the current solution process materials development to show tangible results in 3-5 years.

 

 

Junyeob Lee (Professor, Sungkyunkwan University)

Solution process is favorable for materials optimization. From the initial concentration on polymer materials, recently small molecule materials focused soluble materials development is being carried out, and how to implement common layer is an issue. Emitting layer is using the small molecule materials that are being used as evaporation materials. The difference is the higher cost as the solvent is used. Also, as there is an issue (formulation problem) when used in large area, solution is required.

 

 

Kyoung-Soo Kim (Vice President, Korea Display Industry Association)

Expert acquirement is a key issue. Through upgraded cooperation between industry and academia, and industries, cooperation between panel, manufacturing equipment, and materials has to progress into a positive cycle. Also the open platform regarding new OLED application is needed.

 

 

Young-Ho Park (PD, Korea Evaluation Institute of Industrial Technology)

Flexible display competitiveness acquirement is a big concern. Programs for challenging R&D, and high added value product/technology development, and R&D infra establishment (highly cost-effective R&D) have to be considered.

Sung-Chul Kim, Samsung Display’s CTO, What is Needed for OLED To Enter New Areas?

Sung-Chul Kim, Samsung Display’s CTO, at the 1st OLED Frontier Forum (Jan 28) gave a presentation ‘AMOLED Technical Issue and Future’ and discussed OLED technological issues of the past and present.

 

Kim pointed out the fact that glass substrate is not always necessary for OLED as the most different factor compared to LCD, and emphasized flexible OLED where plastic substrate is used. Kim reported that flexible OLED issues include window’s durability and coating, touch panel’s electrode materials and flexibility, reduction of number of encapsulation layers and flexibility, and backplane’s low stress structure and OTFT application. He revealed that developing spherical stretchable display, which the user can zoom in, is also included in the product roadmap.

 

Regarding transparent/mirror display, Kim announced that this is the direction that OLED should head toward and added that layout design development suitable for different application areas is needed. Specifically, the transparent display should be developed to increase the transmittance area and decrease the TFT area, and the mirror display to optimize the ratio between the total reflection and half-reflection areas.

 

Additionally, in order to produce high resolution OLED, Kim mentioned that innovation in terms of pixel operation and backplane structure is needed. He emphasized compensation circuit and that whether high resolution display can be manufactured cheaply and using simple structure is the key.

 

Kim discussed wall display, IoT, educational display, etc. as the new applications which will become important in future. Particularly, mentioning the automotive display area, Kim explained that for OLED to enter these new areas, plastic materials suitable for each applications and technology that can correctly process this are required. In order for this type of research development to be carried out smoothly, Kim added that cooperation between the academia and industry is necessary.

Looking Ahead to 2016 OLED Industry through Keywords

  1. Flexible AMOLED Investment

In 2016, flexible AMOLED mass production line investment is expected to be actively carried out by Samsung Display, LG Display, BOE, and Japan Display. For Samsung Display to apply flexible AMOLED panel to the new Galaxy model, the mass production line investment is necessary. If they supply flexible AMOLED panel to Apple, volume of the flexible AMOLED mass production to be invested in 2016 is estimated to be grow significantly. LG Display also is expected to actively carry out flexible AMOLED line manufacturing equipment order for Gumi’s P6 line, as well as additional flexible AMOLED mass production line investment following Apple’s demand. BOE is estimated to seriously begin orders for Chengdu’s Gen6 45K flexible AMOLED mass production line.

 

  1. P10

With the announcement of new factory establishment and 1.84 billion KRW investment for part of facilities in Q4 2015, as the first step of the investment, LG Display began site construction for P10 line factory that can produce large area panel. However, the investment direction has not yet been decided. P10 could be directed to only producing large area LCD panel, large area OLED panel, small-to-medium size OLED panel, or large area and small-to-medium size OLED panel simultaneously. China’s Gen8 LCD facilities investment is quite advanced and BOE’s Gen10.5 LCD line investment has also been confirmed. As such how much LG Display’s large area LCD can bring profit has to be carefully considered. Additionally, with the increase of OLED TV consumption and the supply of OLED panel to Apple practically confirmed, OLED investment is essential. P10, Gen11 line, is the world’s largest factory site, and depending on the investment direction in 2016, it is estimated to affect OLED market’s opening time.

 

  1. Chinese OLED

Everdisplay is supplying AMOLED panel to some several Chinese set companies, and Visionox is also expected to actively supply AMOLED panel from 2016. As such, most of Chinese OLED panel companies’ OLED mass production preparation is anticipated to conclude in 2016. Accordingly, second investment by companies including Everdisplay, Visionox, and Tianma is analyzed to be possible and serious movement by China’s OLED industry could occur.

 

  1. Evaporation Equipment

Flexible AMOLED mass production line investment by Samsung Display, LG Display, Japan Display, and BOE, and other Chinese OLED panel companies’ additional installation are expected to be actively carried out from 2016. Amidst this, order of evaporation equipment, OLED production’s essential component, is expected to be an issue.

 

Evaporation equipment currently being used in mass production is mostly Japanese Canon Tokki’s. As this evaporation equipment has been verified in mass production, it is estimated that most companies, including Samsung Display, LG Display, BOE, and JDI, will want to order Canon Tokki’s evaporation equipment. However, as the production capa. of Canon Tokki’s evaporation equipment is limited, the issue is expected to be which panel company will be able to order early. At the same time, this could be a new opportunity for Korean evaporation equipment companies.

 

  1. Samsung OLED TV

At present, the TV industry trend is moving to OLED from LCD. Accordingly, Samsung Display is continuing research to resume their large area OLED for TV panel business. It is analyzed that Samsung Display possesses RGB OLED technology that uses SMS evaporation method, white OLED, and solution process OLED technology. However, as each technology has its drawbacks, they are carefully considering future directions. First, RGB OLED technology is estimated to lack Gen8 mother glass substrate evaporation equipment at present. Solution process OLED method has low material performance. For white OLED, as the key patents are owned by LG Display, technology that avoids these has to be first developed. Therefore, much attention is focused on which technology Samsung Display will use and invest in production line to enter the TV market.
