On January 28, Samsung Electronics, through conference call, analyzed Q4 2015 and announced overall results of 2015. Q4 2015 sales of Samsung Electronics recorded 53,320,000 million KRW, a 3% increase from previous quarter, and 6,140,000 million KRW of business profit, an increase of 1,250,000 million KRW from previous quarter.

 

CE (consumer electronics) department showed highest increase of sales compared to previous quarter. Samsung Electronics revealed that LCD TV is receiving great response in advanced market, and that the sales in North America increased by 94% from previous quarter. They also estimate that the demand will increase in 2016 due to Rio 2016 Olympics

 

However, Samsung Electronics’ IM (IT and Mobile) department mentioned that as the smartphone market growth is expected to remain in single digit and competition between companies will become fierce, estimating that future is not simply bright. As a response to this, Lee emphasized that through strengthening of product and efficient lineup they will maintain the margin of double digits. Additionally, Samsung Electronics’ foldable OLED is rising as the new form factor for product build up. In regards to this, Samsung Electronics revealed that foldable display development is smoothly being carried out and they will deal with mass production and market release timing after discussions with customer companies.

 

With the recent news regarding Samsung Display’s second stage investment for A3 line, there is much interest. Samsung Electronics explained that although A3 related investment is estimated for small to mid-size OLED additional investment, detailed plans have not been confirmed. However, through proactive additional capa. increase, they are planning to strengthen Samsung Display’s competitiveness.

 

Regarding large area display, Samsung Electronics reported that they are the only company that is mass producing by using environmentally friendly quantum dot technology. While revealing pride in SUHD TV’s technology prowess, they also suggested new form factor stating they are looking for the best cost competitive mass production method considering large size OLED marketability through diverse research development.

During the Pioneer Technology Seminar to Overcome Display Industry Crisis (January 14) held in South Korea, Dr. Sung-Kyu Kim of Korea Institute of Science and Technology (KIST) discussed the current issues of glasses-free 3D display and technology development for commercialization. He also revealed related KIST research results.

 

At present, the 3D display applied to TV can be divided into FPR (film patterned retarder) method and SG (shutter glass) method. Both of these methods require 3D glasses. Regarding this, Kim revealed that the glasses using method could be the biggest factor in hindering the 3D display’s accessibility. Kim announced that glasses-free 3D display development is essential particularly for outdoor advertisement applications.

 

To increase the accessibility of 3D display, glasses-free 3D display related research, such as holographic and multiview 3D display technology, has long been carried out. Kim revealed that at present the multiview 3D technology is closest to glasses-free 3D display commercialization. He added that the key issue is how much the 4 problems (crosstalk development, quantization effects between viewpoints, reduced resolution, human factor) can be controlled.

 

In order to solve these problems, Kim applied technology that forms visual field of 4 or more views between eyes and provide same image information in the adjacent area. He emphasized that this was fused with technology that tracks the location of the observer and developed improved glasses-free 3D display. He added that prototype was shown in PyeongChang 2018 Olympics PR venue and Sangwolgok Station in South Korea.

 

Kim explained problems such as human factor occur for TV and monitor where observers watch for a long period of time and future of 3D display is not bright. However, in advertisement area where people can freely watch, it could be effectively applied. He revealed that he will focus on commercialization this year and expedite development.

Quantum Dot, Will it Rise to Become the Answer for Future Display Materials?

/1 コメント/カテゴリ: , /作成者:

The interest in quantum dot materials is increasing daily. In July 2015, Professor Changhee Lee of Seoul National University received Science Technology Person of the Month prize with technology that greatly improves QLED performance and lifetime. In CES 2016, with cadmium-less quantum dot applied SUHD TV, Samsung Electronics achieved UHD TV’s color standard BT.2020 and received much attention.

 

Regarding this interest, during the Pioneer Technology Seminar to Overcome Display Industry Crisis (January 14) held in South Korea, University of Seoul’s Professor Jeong Hoon Kwak reported that quantum dot technology is a material with plenty of potential from the long-term perspective.

 

Quantum dot materials can be used with blue LED to improve LCD color gamut. Two techniques are generally used; the edge type has quantum dot placed on the sides and for surface type the quantum dot film is attached in front of BLU. Most of TV makers, excluding Sony, are using surface type. Professor Kwak explained that quantum dot can achieve desired color by adjusting the size of the particles without changing the materials. Through this, he estimated that it could replace color filter.

 

As well as increasing the LCD color gamut, as quantum dot materials emit light when connected to electricity, much like organic light emitting materials, it is anticipated that they could be used to replace the emitting materials in OLED panel. Within the industry, this technology is called QLED or QD-LED (Quantum Dot Light Emitting Diode) technology. Professor Kwak emphasized that QLED has better color gamut than OLED and has a merit of good actualization of deep blue. As QLED is basically formed through solution process, he added that solution process pixel patterning technology has to be development and device lifetime also has to increase.

 

Professor Kwak explained that as there are not many places mass producing QLED materials at present, the cost is high. However, he emphasized that because the quantum dot materials have an advantage of being easy to synthesize, from long term perspective, they can be used at lower price than OLED.

[Lighting Japan 2016] What is the Key Issue of Solution OLED Materials?

/0 コメント/カテゴリ: , /作成者:

In Lighting Japan 2016 (January 13-16) conference, Sumitomo Chemical and Merck revealed recently developed soluble OLED materials performance results.

 

The soluble OLED materials efficiency published in this conference reached ≥ 65% of UDC’s evaporation materials; particularly, Sumitomo Chemical’s red achieved ≥ 85%, and green reached ≥ 88% of UDC’s evaporation materials efficiency. Lifetime (LT 95) results were not as good as efficiency with red’s 25% and green’s approximately 40% (average).

 

Sumitomo Chemical and Merck both revealed that although in terms of efficiency the soluble materials almost caught up to evaporation materials, but lifetime requires further development.

 

Solution process is a method that allows for large area OLED panel production in RGB method using ≥ Gen8 manufacturing equipment. Key panel companies are actively carrying out research development, and the performance of soluble OLED material is considered the biggest issue. According to Solution Process OLED Report 2015, published by UBI Research, when solution process is applied the material cost can be approximately 40% reduced compared to the current evaporation process using large area OLED panel. The timing for the solution process application to mass production is expected to be decided depending on the development speed of soluble OLED materials.

Skyworth, the most enthusiastic Chinses TV company, placed OLED TV on the front of the CES 2016 booth, the largest space.

 

스카이워쓰1

 

The exhibition concept, same as IFA 2015, was promotion of OLED TV’s superiority over LCD in terms of picture quality and fast response time through car racing game.

 

Furthermore, all OLED TVs exhibited this year are UHD resolution aiming for the premium TV market.

 

According to Skyworth, 2015 OLED TV sales performance is 45,000 units, with the target of 200,000 units in 2016. In 2015, the performance was weak as the OLED panel supply from LG Display was not smooth. However, compared to last year, in 2016 the panel supply from LG Display increased, and as OLED TV is a very popular product in Chinese market due to its superior picture quality compared to LCD the sales target of 2016 became much higher.

 

What is different about this exhibition is the fact that the video clip used in the Skyworth OLED TV booth is the same as the NASA video produced by LG Electronics for promotion. Previously, each companies presenting OLED TV used different contents on the screen. However, in this exhibition, by showing the same video of the sun within the space, they emphasized OLED TV’s superiority in contrast ratio and picture quality of black.

The exhibition showed rapid development of LG Display’s OLED technology.

OLED Takes Over Monitor and Notebook Markets Too

/1 コメント/カテゴリ: , /作成者:

Following the mobile and large area panel markets, OLED is now actively entering the monitor market.

 

Until now, the monitor and notebook markets were mostly occupied by LCD. Burn-in effects and power consumption were the biggest reasons that prevented OLED panels from being applied to monitor and notebook. Generally, monitor and notebook are for office use. Within the office environment, window’s task bars and icons on the main screen are fixed. Also, as the average hours of use is much higher than TV or mobile, burn-in effects is an issue. Also as Office programs or internet browsers, which usually have white background, are used heavily, power consumption is high as OLED panel of RGB method has to drive all subpixels in order to actualize white.

 

Starting with the black and white OLED monitor in 2012, Sony steadily developed/mass produced OLED monitor. However, it is analyzed the application was possible as this OLED monitor was mostly used for medical and broadcasting uses and in different settings from the office monitor environment.

 

However, with Lenovo and HP’s announcements of OLED Notebook release, the status is changing.

 

In January 2016, Lenovo announced world’s first OLED notebook ‘X1 Yoga’ with 14 inch AMOLED panel with 2550×1440 resolution. Following this, HP also announced the release of 13.3 inch OLED hybrid laptop/tablet ‘Specter X360’ with 2560×1600 resolution.

 

These OLED panel equipped notebook releases break the existing perception that OLED panel is not suitable for monitor and notebook, and can be considered that OLED panel’s lifetime and power consumption have been achieved to be suitable for monitor and notebook. As such, much attention is on whether the OLED market will be able to greatly expand in the monitor and notebook markets following their success in mobile and TV markets.

Looking Ahead to 2016 OLED Industry through Keywords

/0 コメント/カテゴリ: , , , /作成者:
  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.

  1. OLED TV

OLED TV, first released in Q4 2013, recorded approximately 50,000 units of shipment each in Q1 and 2 this year. The shipment increased to 100,000 units in Q3, more than twice the amount of each quarter in H1 2015. As it is estimated that close to 200,000 units were released in Q4, over 90% of LG Display’s 2015 target is expected to be achieved. This is considered to be showing price competitiveness against other TV as the price of OLED TV fell to 1/2 of the initial price and effectiveness of aggressive marketing emphasizing the advantages of OLED TV compared to newly released LCD TV. In Q3 earnings results announcement, LG Display revealed their plan of 1,000,000 units of OLED TV panel shipment in 2016 and forecast OLED TV’s growth. For the industry, 2015 has been the year that secured foothold for OLED TV’s market expansion.

 

  1. Galaxy S6 Edge

At the time of Galaxy S6 and Galaxy S6 Edge’s release, Samsung Electronics estimated the initial supply to be 50:50. However, Galaxy S6 Edge showed 70% in actual demand and this led to shortage in supply. Samsung Display met the demand by starting flexible AMOLED line operation earlier than scheduled. 2015 proved future market growth potential by opening consumers’ wallets through designs possible only with flexible AMOLED panel.

 

  1. Samsung Display Supply Diversification

During the Q3 earnings announcement, Samsung Display revealed their plan to expand non-Samsung clients by 30%. Accordingly, in Q3, when smartphone market’s growth was expected to slow down, the sales performance improved by 13% compared to its previous quarter through key client’s new product release and expansion of client base. Particularly, the market occupation of AMOLED panel shipped toward China is analyzed to have increased within the global mobile market as Chinese set companies released AMOLED panel equipped smartphones.

 

  1. Apple’s OLED Application

Apple, which has been using LCD panel for all products, first applied flexible AMOLED panel, produced by LG Display, to 2015 smartwatch Apple Watch and drew much attention. In H2, Apple diversified suppliers by using Samsung Display’s flexible AMOLED panel. This move is analyzed to be groundwork for flexible OLED application to smartphone following smartwatch. 2015 has been a year with much interest in when flexible AMOLED panel equipped iPhone will be released.

 

  1. OLED Lighting

Global OLED lighting industry went through a great transformation in 2015. OLEDWorks announced they will acquire key parts of Philips’ OLED lighting business, relevant production facilities, and intellectual property. With this take over, OLEDWorks greatly expanded business through widened product portfolio and simultaneous lighting panel mass production in the US and Germany. LG Chem. transferred OLED lighting business to LG Display. The value of transfer is 1.6 billion KRW, and it is seen to be a strategy to increase competiveness by transferring the business to LG Display with their OLED panel mass production knowledge and to focus on existing materials business. The take over and business transfer of the main players in OLED lighting industry, OLEDWorks and LG Chem., are following their own business strategy. However, following these moves, related investment is expected to be delayed for some time and eyes are on how these will affect the OLED lighting business overall.
