With diverse merits, OLED application is increasing to include notebook, tablet, monitor, etc. Accordingly, Samsung Display’s OLED panel is being actively expanding to this market.

HP recently began shipping Spectre 360, a notebook equipped with Samsung Display’s 13.3 inch OLED with resolution of 2560 x 1600. Previously, in CES 2016 (6-9 Jan) Samsung Electronics revealed Samsung Display’s 12 inch OLED equipped Galaxy Tab Pro S, and HP and Dell also presented Samsung Display’s 13 inch mark OLED equipped labtop.

In SID 2016 (22-27 May), Samsung Display presented 2560 x 1440 resolution 13.3 inch and 14 inch OLED for notebook and actively targeted the notebook market. Following this, a Korean press reported that Samsung Display will stop production of TN panel, low resolution LCD panel for notebook and monitor. That Samsung Display is actively targeting the notebook market is analyzed to be a strategy to create premium market advocating diverse advantages of OLED.

Due to superior contrast ratio, OLED’s picture quality is clearer in comparison to LCD, and easy to create premium market as the weight can be lighter than LCD. Burn in effect, considered one of OLED’s drawbacks, is also known to have been much improved.

As the price of OLED is higher than LCD at present, specialist market, such as medical, should be targeted first. However, when the price competitiveness improves in future, popularization of OLED is anticipated. Accordingly, Samsung Display is actively taking action in notebook and tablet OLED market expansion. UBI Research reported that 2016 Q1 OLED panel shipment for tablet increased by more than 10 times compared to the same period in 2015.

According to UBI Research’s 2016 OLED Display Annual Report, the 11 inch – 13 inch, notebook and monitor use, OLED panel shipment is expected to record 100,000 units this year, and this is expected to increase by 10 times in 2020.

Samsung Display’s recently revealed 5.5 inch 806 ppi AMOLED is expected to contribute to the expansion of the global VR (virtual reality) market as well as providing synergy for both Samsung Electronics’ future VR and smartphone business.

In SID 2016 (22-27 May), Samsung Display revealed 5.5 inch AMOLED with resolution of 806 ppi. This 4K UHD display has the highest resolution for 5 inch mark AMOLED in industry.

The response speed of AMOLED is approximately 1,000 times faster than LCD and can actualize much superior picture quality due to exceptional contrast ratio. The reduced amount of harmful blue light is also another merit of AMOLED, and it is becoming the general trend for display for VR display.

Even at the same resolution, the visual effects for smartphone and VR device are different. For example, 577 ppi QHD resolution applied to Galaxy S7 can actualize quite clear picture quality for smartphone. However, when the display is directly in front of the eyes, in cases of VR, aliasing effects, when what is on the screen looks jagged, occurs. In order to produce clear picture quality with almost no aliasing effects in VR, expert believe that 1,500 ppi is required at minimum. However, the current VR AMOLED only can actualize up to high 500 mark ppi.

That Samsung Display displayed AMOLED with resolution of over 800 ppi for the first time should be noted. With this resolution, aliasing in VR can be significantly improved even if not perfectly. Furthermore, this AMOLED has the same brightness as the Samsung’s Galaxy S7. Considering the production yield improvement, this display could be used for Galaxy S8 (TBA) that is expected to be released in 2017. For VR device connected to smartphone, smartphone’s resolution is directly related to the VR’s picture quality. This means that the Samsung’s 806 ppi 5.5 inch AMOLED allows for UHD smartphone production as well as the introduction of VR with upgraded picture quality.

UBI Research explained that while some believe that ultra-high resolution is not necessary in small screen such as smartphone, the 4K UHD 5.5 inch AMOLED is significant in that smartphone is linked with VR which market is being opened. He added that the 806 ppi AMOLED recently revealed in SID 2016 by Samsung will contribute to the expansion of the global VR market as well as providing synergy for both Samsung Electronics’ future VR and smartphone business.

Of the new OLED display equipped products released in Q1 2016, smartphone and wearable products significantly increased compared to the same period in 2015. However, for OLED TV sector, no news was reported in Q1 other than LG Electronics’ new product.

According to UBI Research, 17 new OLED equipped smartphones were released in Q1 2016. This is 4 more than Q4 2015, and 12 more than Q1 2015. Of these, Samsung Electronics released 4 smartphones including Galaxy S7 and S7 Edge, responsible for the largest proportion. Following Samsung, ZTE, Gionee, Acer, and BLU each launched 2 OLED smartphones, and Vivo, HiSense, Konka, HP, and Microsoft released 1 each. Of the companies, 6 are from Greater China Region.

For OLED equipped wearable new products, 7 were released in Q1, 2 more than Q4 2015, and 4 more than Q1 2015. Sony, Oculus, HTC, and Sulon released new VR products. Epson released smartglasses, and Fitbit and Intex released smartbands. OLED wearable market showed much activity in Q2 2014 with over 20 new products centering around smartwatch and smartband products, which quietened down since then. However, with recent new releases of VR and smartband devices, the market is being rejuvenated.

LG is still dominating the OLED TV market. LG Electronics was the only company to release new OLED TV in Q1, and released 4 products in 55 inch – 77 inch. The market showed some movement in Q1 2016 when several Chinese companies, including Haier and Changhong, released OLED TV. However, since then the market, except for LG, has been quiet. This is analyzed to be due to high price of large area OLED panel, panel supply shortage, etc. In Q2, China’s Skyworth released a new product but the sales are known to be less than anticipated.

One expert explained that large area OLED still have issues that need to be solved compared to small OLED including price competitiveness. He added that latecomers such as Chinese companies are slow to select OLED for TV compared to smartphone.

2010年3月、サムスン電子で初のGalaxy Sが発売されて以来、6年間で合計9タイプのGalaxy Sシリーズがリリースされたが、画面サイズは1.5インチ大きくなっており、解像度は約10倍増加したことが分かった。

UBIリサーチが最近発刊した「Galaxy SシリーズのAMOLED特性分析報告書」によると、「Galaxy S」から「Galaxy S7 Edge」に至るまで、このシリーズに装着されたAMOLEDパネルは、4インチから5.5インチに、1.5インチが増えた解像度は480×800 WVGAから1440×2560 QHDと、9.6倍も増加した。

Galaxy Sシリーズに搭載されてきたAMOLEDの変化の推移を見ると、2017年にリリースされる「Galaxy S8」は、5インチの中・後半台になると予想され、解像度はUHD 4K（800ppi）になると予想される。

2010年3月Galaxy Sの初期モデルが4インチ画面で発売されて以来、毎年増加しており、S7とS7 Edgeは、それぞれ5.1インチ、5.5インチで発売され、初期のSに比べて約30％以上も画面サイズが増加している。

サムスン電子は6インチ台のスマートフォンも発売したが、2015年に6インチ台の製品は消え、5インチ台の画面サイズがサムスン電子全スマートフォン製品の71％を占めるようになった。

これまでサムスン電子では、Galaxy SのWVGAを皮切りに、S3はHD、S4とS5はFHDを経て、S6とS7は、QHDまで製品の発売が行われた。

Galaxy Sシリーズは、S3のHD解像度を除いては、現在の解像度の開発サイクルが2年ごとに次の解像度に移っている。

このような傾向のままでいくと、2017年にリリースされるGalaxy S8は、5インチ代の半ばから後半の画面サイズでUHD 4K解像度を備えるものであると期待できる。

UBIリサーチの関係者は、「最近、サムスンディスプレイがサンフランシスコで開催された「SID 2016」にVR用に展示したUHD 4Kの806ppiを備えた5.5インチAMOLEDは、輝度がS7と同等レベル」とし、「生産歩留まりの改善などを考慮すると、このディスプレイは来年に発売されるGalaxy S8に採用されるものと予測される」と説明した。

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.

CTO of  JDI , Hiroyuki Ohshima, estimated that the display will evolve to flexible and human friendly, and emphasized that LCD is not suitable for flexible

During his keynote session in SID 2016 (22-27 May), Ohshima discussed the future of display. He explained that the display will evolve to System Integrated Display that combines different technologies and toward flexible.

Display is expected to become more interactive with human body. Beyond touching the screen with fingers, biological signals will be recognized such as heartbeat, eye gaze, fingerprint, and palm print. Through these, display will evolve into an input device that moves deeper into people’s lives.

For these to become a reality, Ohshima explained that diverse technologies such as touch, recognition, security, health care function, pen input need to be applied to the display. He stressed that display is heading toward flexible and noted LCD’s limitation regarding this issue.

Ohshima told the attendees that as LCD requires backlight and glass substrate is used, it is not suitable to actualize flexible panel. For OLED, it is expected to move forward to flexible and foldable exceeding ultra-thin and curved. However, he added that OLED still has several issues that need to solved including not being able to follow LCD in terms of pixel density.
