LGディスプレイがPOLEDスマートフォン時代を先制攻撃するために、坡州(パジュ)事業所に約2兆ウォンのPOLED投資を断行すると27日発表した。

LGディスプレイ（代表取締役副会長ハン・サンボム、韓相範/www.lgdisplay.com）は、26日定例理事会を開き、京畿道坡州事業所内のP9工場に、月1万5000枚規模の6世代（1,500㎜×1,850㎜）プラスチック有機EL生産ラインの構築のための1兆9,900億ウォンの投資を決定した。

POLEDは、ガラス基板の代わりにプラスチックを使用するため、円形、多角形などの2次元デザインはもちろん、ベンダブル、ローラブル、フォルダブルなど、フレキシブルディスプレイに代表される3次元デザインへの革新を可能にする。

有機EL専門リサーチ会社であるUBIリサーチは、2016年のフレキシブル有機EL出荷量が約7,670万台から2020年には6億5,310万台に大きく成長すると見込んでいる。また、別のディスプレイ市場調査会社IHSは、フレキシブル有機EL市場が2016年には約5,900万台から2020年には約4億1,600万台に成長するものと予測する。

LGディスプレイは、これらの市場の拡大に積極的に対応するために、慶尚北道にある亀尾（グミ）事業所に6世代POLED生産ライン（E5）を投資したのに続き、坡州事業所にも約2兆ウォンの6世代生産ライン（E6）を追加投資する。

一方、LGディスプレイは今回の投資の効率性を最大化するために、坡州に約5,000億ウォン規模の関連インフラの造成を進めており、亀尾に続き、坡州でP生産が2018年に本格化されれば、LGディスプレイはPOLED、スマートフォン事業の拡大の基盤を作ることになる。

LGディスプレイは、今回の投資を発表した第6世代生産ラインのほか、月1万4,000枚規模の第4.5世代P有機EL生産ラインでスマートウォッチなどを生産しており、現在、建設工事中のP10工場に、今後10兆以上を投資して、有機ELを通じたディスプレイのルネサンス時代を開く覚悟である。

LGディスプレイのハン・サンボム副会長は、「ディスプレイ産から有機ELへのパラダイムシフトは、新たな挑戦でありチャンスである」とし、「LGディスプレイは、適期の投資と投資効率を最大化して、未来の成長動力として浮上する有機EL市場で必ずトップの地位を確保する」と述べた。

一方、2013年1月、世界初の55インチ有機ELテレビパネルを量産して、本格的な大型有機EL時代の幕開けを宣言したLGディスプレイは、POLEDにおいても2013年10月世界初の6インチのスマートフォン用POLEDを量産したことに続いて、2014年9月には世界初の1.3インチの円形POLEDを量産するなど、着実に関連技術とプロセスのノウハウを蓄積してきた。

One of the issues of flexible OLED actualization is acrylic’s vulnerability against lower temperature, and silicone is emerging as a solution. Meanwhile, Momentive is attracting attention with their promotion of silicone based InvisiSil.

One of the key encapsulation technologies for flexible OLED is TFE (thin film encapsulation) that laminates thin inorganic and organic films, used by Samsung Display. Of these, organic material is formed through inkjet OLED process using acrylic materials. However, acrylic organic materials are easily broken under 0 ℃, which leads to difficulties in producing flexible OLED using these. However, silicone based materials can withstand up to -40 ℃ and are considered strong candidate for acrylic replacement.

Momentive is a company that develops such silicone based materials. In SID 2016 (22-27 May), Momentive opened an exhibition booth and presented InvisiSil Snap Cure silicones. The InvisiSil Snap Cure systems can cure rapidly at room temperature without UV exposure.

Momentive explained that for flexible AMOLED panel to move past edge type and toward true flexible such as foldable and rollable, silicone is much better suited than acrylic. Furthermore, they added that silicone based materials have yet revealed any disadvantages compared to acrylic, and that it is in development for continued application to mass production.

LG Display announced today that it is showcasing its latest advanced OLED light products and solutions at Light+Building 2016, one of the leading global trade fairs for lighting and building services technology, in Frankfurt, Germany, from March 13th to 18th.

Eleven OLED light panels are being exhibited along with four solutions using the panels. LG Display is highlighting the key advantages of OLED light, including the design flexibility that makes it suitable for different applications and venues, as well as its supreme light quality which is closest to natural light, thereby making people feel comfortable and reducing eye fatigue.

The company is exhibiting four solutions using OLED light panels:

Flexible Solution Section

The flexible OLEDs can be used to create unique and creative decorative lighting fixtures. The creativity in design increases along with the length of the panels. The flexible OLED light panels are light-weight and unshatterable. There are applications using 200x50mm flexible panels and 406x50mm flexible panels. The main highlight in this section is an application using many 320x320mm flexible panels.

Transparent Connection Solution Section

The LG Display OLED light panel generates a floating light effect by attaching the panel to glass and providing power through metal mesh transparent conductive film. It can be applied to display cabinets, shelves, and furniture. Especially when it is applied to shelves at stores, the lack of heat preserves product quality while the lack of shadow makes them more visually appealing to customers. The simplicity of OLEDs opens up the possibilities of various designs and applications.

Mirror Solution Section

By embedding the OLEDs into mirrors, LG Display has created a solution that can have a variety of uses. It can be used as a mirror in upscale hospitality settings or as a unique display box in high-end retail stores. When other light sources are used in a mirror solution, they tend to make the mirror too thick whereas OLED keeps the mirror thin and also minimizes glare.

Module Solution Section

OLED light panels allow for easy installation in diverse settings. LG Display is introducing super-slim OLED light modules at the fair with a simple aluminum housing that connects multiple panels into each module, generating unique and sleek designs. The company is showcasing the module solutions in order to demonstrate how well OLED light can be applied to interior design and architecture. It is committed to develop other solutions in order to encourage more and more people to easily use OLED lights.

On the first day of OLEDs World Summit (October 27-29) held in Berkeley, USA, Samsung Display and LG Display gave their talks back to back. Samsung Display’s Vice President Chang Hoon Lee and LG Display’s Joo Soo Lim discussed their thoughts on OLED under the titles of ‘The Future of OLEDs’ and ‘A Future Game Changer’ respectively.

Samsung Display’s Lee, who gave his presentation first, reiterated Samsung Display’s leadership position in the mobile market and how Samsung Electronics’ recent mobile display reflects this. Comparing RGB pixel structure and their own diamond pixel structure, Lee drew comparison between human eyes and diamond pixels; due to cell distribution in eyes, humans are more sensitive to green colors and that diamond pixels reflect this by having twice as many green subpixels as blue and red ones. The diamond pixels also maximize the sub-pixel packing and increases the PPI.

Regarding the advantages of OLED display, Lee gave 2 examples using Samsung Electronics’ latest smartphone models. Utilizing the fact that selective control of each pixel is possible in AMOLED displays, Samsung provided Vision Aid to help people with color blindness. OLED’s ability to achieve total black is used in Super Dimming function where screen brightness can be reduced to 2nits to be used in the dark environment.

LG Display’s Lim revealed that an adult in the US spends 9 hours 40 minutes a day on average looking at one form of display or another. Highlighting the need and importance of quality display, Lim also discussed advantages of OLED display over LCD such as total black, 3D effects, and color gamut.

As the future OLED display, Both Lee and Lim placed slightly more emphasis on flexible (plastic) OLED than transparent or mirror display. Samsung Display discussed requirements necessary for a successful flexible display in more depth touching on the need for suitable cover window, flexible touch (sensor), flexible encapsulation, and flexible backplane. On the other hand, LG Display discussed flexible display’s design freedom and its influences on the wearable, mobile, and automotive markets. Lim also placed much importance on how flexible OLED can be used in virtual reality display market. The 2 speakers ended their talks affirming the need for new display market and innovation through OLED technology and new applications.

The presentations given by the 2 apparent leaders in the OLED display industry were remarkably similar with both speakers underlining major points of OLED in broad strokes. The need for solutions for future OLED, whether it be flexible, transparent, or mirror display, through innovation and technological advances is an absolute truth if not maybe too obvious. There also may be some comfort to be had in the shared vision within the OLED community. However, it is also a fact that numerous attendees of the conference commented on the similarities of the 2 presentations and the lack of any surprises.

In SID 2015 Display Week (31 May – 5 June), LG Display’s CTO In Byeong Kang gave a keynote speech. He explained that future display in everyday lives will be actively applied to home, office, street, and mobile device areas through various applications including window, ceiling, mirror, kitchen, automotive, desk, commercial, and wearables. He added that OLED will be the answer to key technology of flexible display (curved, rolling, and folding), large-area transparent, and excellent image quality.

Key issues of flexible are bending radius and reliability. Kang emphasized that in order to reduce the bending radius, thinner substrate is needed, and to improve reliability, new material, components development, and internal and external shock mechanism research is important. He mentioned that although OLED is good for transparent’s transparency, light control, and reflectivity as key technology, LCD and LED display also have advantages of their own in transparent display realization. Kang concluded the presentation with the emphasis on the need of expansion into automotive, watch, architecture, and furniture companies from existing panel, material, and components companies’ ecosystem for commercialization of flexible and transparent display.

LG Display is currently mass producing plastic OLED panel for smart watch, and aiming for 80% automotive display market occupation in 2018 with approx. US$ 2,000,000,000,000 of revenue. In SID 2015, LG Display exhibited 18 inch rollable OLED panel, and 12.3 inch automotive OLED panel. Through the OLED and ecosystem’s expansion, it is anticipated LG Display will lead flexible and transparent display market following OLED TV.SID2015

LG Display succeeded in developing world’s first flexible and transparent OLED.
LG Display announced the technological development of world’s first 18-inch flexible OLED and transparent OLED of same size, disclosing at the ‘national project workshop for transparent flexible display development’ to be held from July 10 till July 11.
It is considered that LG Display secured the foundation technology for developing a large screen transparent flexible display through the simultaneous development of flexible and transparent OLED this time.
The flexible OLED that LG Display developed is 18-inch in size with HD resolution (1200 X 810) nearly 1 mega pixel quality, and this is the largest OLED in the world, realizing the radius of curvature of 30R. This means it can be rolled up to a radius of 3cm with no operational complications and implies that it is possible to implement a large panel rollable TV over 50 inches in the future.
In order to realize maximum radius of curvature even on 18-inch screen, LG Display used Polymide film of polymer materials on a substrate that TFT and organic matters are deposited, reducing the thickness and increasing flexibility drastically.
Furthermore, this concurrently developed transparent OLED is of same size and resolution as flexible OLED and the transparency is 30% or higher realized by self-developed transparent pixel design technology. It is a radical increase of transparency, given that transparency of existing LCD based transparent display is about 10% or so.
LG Display maximized the degree of completion by lowering the haze caused by circuit element and film down to 2%.
The transparent flexible display is a national project of the future industry-leading technology development program promoted by the Ministry of Trade, Industry & Energy and the Korea Evaluation Institute of Industrial Technology, and LG Display is the leading participants of total 36 organizations of industries, academies, and institutes, aiming to develop a large 60-inch transparent and flexible display by 2017.
According to In-Byung Kang, Senior Vice President and Head of the R&D Center at LG Display, “Pioneered OLED TV market, LG Display is leading future applied technology of OLED,” and “Though there still are many challenges to be resolved, we are confident in developing transparent flexible display of over the 60-inch screen UHD (Ultra High Definition) screen with transparency of 40% and a curvature radius of 100R by 2017.”
