Who has a key to OLED, JDI or JOLED?

As participation of Taiwanese and Chinese enterprises in OLED panel business, which is dominated by Korea, is taking place, the Japanese government begun its active involvement in the OLED business. “Innovation Network Corporation of Japan (INCJ),” a private and public fund led by the Japanese government, established Japan Display Inc. (JDI) by gathering a display team with Sony, Hitachi and Toshiba who have mobile display technologies to save the uncompetitive display industry of Japan. A mission of JDI is to produce LCD and OLED for mobile devices.

Last month, INCJ set up JOLED with JDI, Sony and Panasonic for the OLED production and each OLED related department of the companies will be united in January 2015 to manufacture over medium size OLED.

Considering the process of JDI and JOLED establishment and future trend of technology, Sony is expected to be responsible for core technology and play the key role. Sony is the only OLED maker as well as mobile device and medium size monitor in Japan. All these items have LTPS TFT and RGB OLED structure using vacuum evaporation method. Also, the OLED TV by Sony is composed of oxide TFT and WRGB OLED structure. Sony is not manufacturing the OLED panel for mobiles and TVs but is certainly a leading company who owns all the technologies.

The OLED developed by JDI is 5 inches and uses LTPS TFT and WRGB OLED technology. It is considered that Sony’s technologies made JDI possible to develop the OLED panel in such short period.

As commercialization of JDI’s OLED delays, the new JOLED was born. JDI, Sony and Panasonic joined it only for the OLED. JDI has the majority of the voting rights of JOLED, but Sony has a large portion of JDI shares. Thus, it seems that Sony will be the main party of JOLED.

Hence, Sony’s super top emission technology is expected to be applied to 10” OLED panel by JOLED. Sony’s oxide TFT and WRGB OLED technology applied large size OLED panel will be used for UHD high luminance product with super top emission structure. Production will be in Gen8 oxide TFT line owned by Panasonic.

It is difficult to commercialize ink-jet technology of Panasonic because characteristics of its luminescent materials do not reach that of WRGB materials. The OLED roadmap of Sony, however, has the flexible OLED using the OTFT and ink-jet technology. It may take time but flexible signage is expected to be seen at a very low price.

KITECH, Developed the world’s first refining technology for organic light-emitting material using ILs for OLED TV

Dr. Taewon Kim’s team of photovoltaic energy convergence research group of Korean Institute of Industrial Technology (KITECH, President Yong-Soo Lee) developed an original technology to refine organic light-emitting materials in bulk for fine OLED TV at low price.

Dr. Kim’s team established a new concept for the refining technology by using Ionic Liquids (ILs), and it can solve issues of high cost·low yield rate arisen in production of the organic light-emitting material for the OLED TV.

Ionic Liquids are liquids that only consist of positive and negative ions at room temperature and stays in liquid form at high vacuum (~100℃) with almost no volatility. Recently, ILs became a future clean solvent in green chemistry field with a strength of good solubility for high molecular substance and a feature of metal salts.

Until now, ‘sublimation refining method’ has been used to get high purify organic light-emitting material by utilizing the difference of sublimation points between vaporization and solidification of a material. However, cons of this method are low yield rate and very high production cost because it is impossible to realize complete auto and continuous process.

To address this issue, Dr. Kim’s team started developing the large scale refining technology for the organic light-emitting materials at low cost since 2011 and applied for original patent in December, 2012. Their effort on verifying the possibility of the technology’s application produced this result in 19 months.

The key of the result is the application of the high purity refining technology on the organic light-emitting material for the OLED TV by focusing on the non-volatile feature of ILs at high vacuum·high temperature.

This technology uses a principle of separating impurities in the order of vaporizing the organic light-emitting material in a vacuum chamber; dissolving it in a liquid filter of ionic liquid; and recrystallizing supersaturated material in the liquid. It enables to get 99.95% of high purity organic light-emitting material through one refining process.

It is a completely new concept of large scale refining method based on the non-volatility characteristic of ionic liquid at high vacuum·high temperature.

The team is credited with the success of new technology development which can overcome the cons of the existing sublimation refining method including refinery yield rate, automation and continuous process of equipment, and efficiency of mass production. It is also expected to bring a huge cost reduction effect by recycling; collect and reprocess during refinery process, of the expensive but non-volatile ionic liquid.

According to “2014 OLED Emitting Material Annual Report Market Forecast (~2020)” by a professional OLED market research firm, UBI Research, the OLED emitting material market is expected to grow to 1.3 trillion won in 2017 from 2014 estimation of 543 billion won. Forecasted annual growth rate is over 30% and experts see that the growth will be much larger if large size display market including the AMOLED TV expends in full-scale.

Dr. Taewon Kim, said, “this technology increased the yield rate and decreased the production cost by more than 50%. And an ultimate goal is to reduce the current price by one tenth” and “technology development is in progress with companies.” He also said, “the success is a game changer with enormous potential to turn the OLED TV market-to-explosively grow” and “based on the low-cost and large scale refining original technology, domestic businesses will largely contribute to preoccupy the global market of forward-backward industry regarding the OLED TV.”

The team currently applied 16 cases for patent with related process․equipment technology in and out of the country and plans active technology transfer to related businesses.

Launching of Gionee’s ultra-thin AMOLED smart phone (5mm) is imminent

Ctimes, a Chinese medium, reported that a Chinese smart phone maker, Gionee, will introduce an ultra-thin smart phone modeled GN9005.

GN9005 used AMOLED panel and is 0.55mm thinner than 5.55mm of the previous model, which was introduced as Elife S5.5 last February.

It is noticeable that 4.8” HD AMOLED panel is applied which is smaller than the 5” FHD Super AMOLED applied to the previous Elife S5.5. In general, the AMOLED panels produced by Samsung Display are named super AMOLED. However, no particular name for the AMOLED panel applied to GN9005 and its low performance indicate that the panel is highly likely to be supplied by AUO.

It is known that AUO has started supply to a Chinese maker from last June but any specifics on the maker has not been revealed.

A Chinese smart phone maker, BBK, drew attention with 5.75mm VIVO X3 after the launch of 6.18mm Ascend P6 by Huawei last year. Followed by launching, Gionee introduced the 5.55mm Elife S5.5 in February and will launch 5mm GN9005 and that fierce competition will begin soon in the ultra-thin smartphone market in China.140722_GioneeElifeS5.5vsGN9005

Sony unveils Head Mounted Display (HMD) for medical care

Sony displayed a system, which enables you to check endoscope video through Head Mounted Display (HMD) at International Modern Hospital Show 2014 held from July 16th to 18th, 2014. For the existing endoscopy surgery, posture restriction exists because the procedure requires external monitoring. With Sony’s new product, surgery, however, can be performed without the posture restriction.

This specialized product for medical purpose weights only about 490g which enables an operator to perform in a standing position. It doesn’t fully cover eyes of an operator by changing the shape of wearable belt so that the operator can visually check surgery device by lowering the eyes without taking it off.

This medical HMD is installed with Sony’s OLED display and shows images on the OLED display individually thus crosstalk is not that large and doesn’t induce dizziness during its use.

 Sony consulted with doctors to develop this system and said that demand for this competitive system will increase as 3D endoscope increases.
