サムスンディスプレイのイ・ジョンソ主席研究員は、「VR•AR市場は、過去3Dテレビ市場とは異なり、肯定的であるという観点を提示した。

8月23日、済州島済州ICCで開催された「インダストリアル・フォーラムで、イ・ジョンソ主席研究員は、「VR/ARのためのディスプレイ技術」というタイトルの基調講演で、VR•AR市場が過去3Dテレビ市場とおなじような道を歩くであろうと一角の懸念にについて言及した。

イ・ジョンソ主席研究員は、「3Dテレビ市場は、コンテンツ生産および3D転換技術の限界、3Dディスプレイの低品質、標準の不在などで活性化されなかった」とし、「しかし、VR・AR市場は、ポケモンGO、ホロレンズなど、すでにコンテンツとハードウェアが登場しており、数多くのメーカーがこの分野に参加している」と述べた。

Apple、マイクロソフト、インテル、facebookなど、屈指の企業がVR・AR分野のために積極的に投資しており、生態系が形成されているというのが彼の説明である。

イ研究員は、ゴールドマン・サックスの資料を引用して、「VR・AR市場は、2025年までに850億ドルの規模を形成するであろう」と強調した。

イ研究員は、さらにバーチャルリアリティ(VR)と拡張現実(AR)分野に有用な有機ELの技術的特徴を説明した。特に透明有機ELが拡張現実(AR)技術を具現するための核心ソリューションであると強調した。

彼はARについて「実際、物理的環境やリアルタイム画面に加わるデジタル経験である」と説明し、「透明ディスプレイがこれを具現してくれる」と述べた。

有機ELは、LCDに比べて透過率が高く、透明ディスプレイを作るための最適なソリューションとして考えられている。この研究は、「透明有機ELの具現のためには、高い透過率と低い抵抗のカソード(cathode)が必要であり、基板(substrate)が熱によく耐え、フレキシブルが可能でなければならない」と説明した。

また、透明ディスプレイの透明領域にメタル類を適用すると、ミラー(mirror)ディスプレイで具現され、鏡のような形としてもARを楽しむことができる。そのためには、高い反射率と高度の色域(high color gamut)が必要であるというのがイ・ジョンソ主席研究員の説明である。

Planar Aims for Transparent OLED Product Mass Production in Feb 2016

On November 30 (local time), a US based display production company Planar held an online presentation titled ‘Planar Look Thru OLED Transparent Display Webinar’, discussing transparent display traits and disclosing specifications for products which are estimated to be mass produced from February 2016.

 

Transparent display is defined as a display with see-through screen showing objects behind the display as well as the display contents. Recently, it is receiving much attention as a technology with high potential for diverse applications expanding existing display industry.

 

Planar explained that unlike the existing display, transparent display pixels are separated into transparent and emitting areas with RGB subpixels located in the emitting area. Planar clarified that what is black on general display becomes see-through and white becomes opaque.

 

Transparent display’s performance is decided by several factors such as transmittance, brightness, and color gamut. Regarding this, Planar revealed that the transmittance of transparent display is not fixed but can be affected by ambient light; brighter the surrounding environment, higher the transmittance. Additionally, viewers have tendency to perceive the display with higher color gamut as brighter than the actual brightness, and transparent display’s color gamut is therefore an important factor.

 

In early 2015, Planar revealed a 55inch transparent OLED display prototype. At present, Planar is receiving pre-order and aiming for mass production in February 2016. The company also reported basic specifications for the panel: 45% of transmittance, 100% color gamut, and Full HD (1,920×1,080) of resolution. The product also has 5 input sources: 4 HDMI terminals, and 1 display port.

 

During the webinar, Planar explained that 32 touch points using IR (infra-red) touch system installation is an option. Although this is less accurate than touch system using touch film, Planar explained that this was an unavoidable choice in order to increase the transmittance. They also added that they are continuing research for new touch system application.

 

The 55inch panel price starts from under USD 15,000 and Planar is currently receiving pre-order. Although there are many factors that affect transparent OLED’s lifetime, it was measured to be 20,000 hours at LT50. Answering the question on whether it is affected by UV light, Planar explained that it can be UV sensitive and the product was designed to be an indoor installation.

 

It is estimated that the transparent OLED panel used in the Planar’s product released is produced by Samsung Display as it has the same 45% transmittance, 1920×1080 resolution, and 400nit brightness.

LG’s Plastic OLED, What’s Next?

LG Electronics showcased smart car related technology collaboration by supplying components for Gea. Gea, revealed by Italdesign Giugiaro on Mar 3 (Korean Time), in Geneva International Motor Show 2015 (Geneva Palexpo, Geneva, Switzerland) is an autonomous luxury concept car.

LG Elec. and Italdesign’s concept car technology collaboration items are in-car display, tail lamp/camera, and IoT (linked with smart car).

For in-car display, 6 inch HD curved plastic OLED (P-OLED) was used in the front and rear console, and 12.3 inch full HD display was supplied for dashboard and CID (Center Information Display), and the passenger side. 19 inch LCD has been converted into to provide large screen for RSE (Rear Seat Entertainment). As thin and flexible design is possible with plastic OLED, it is suitable for the interior of a vehicle with its various formation. It is also appropriate for automotive display as advantages such as the high contrast ratio and fast response time reduce driver’s eye strain. Therefore, in-car display is estimated to be new application for OLED display in future.

 LG Display, panel supplier of LG Elec., have made an announcement of their target to secure 30% of world’s market share in automotive display in 2018, and revenue of approx. US$ 2 billion. In CES 2015, held earlier in the year, they presented 13.1 inch automotive display and new 21.5 inch curved products for dashboard and CID. LG Display is planning to target automotive navigation/dashboard/entertainment display.
