2014年 8月 30日/0 コメント/カテゴリ: ディスプレイ, フォーカス・オン /作成者: OLEDNET

Touch Taiwan 2014 was held in Taipei, Taiwan from August 27 to 29 with 430 material and equipment businesses including AUO and Innolux which are representative panel makers of Taiwan.

Announcing the company’s UHD curved LCD TV full lineup from 42-inch to 85-inch, public information display, displays of various applications, and high resolution LCD panel and AMOLED panel for mobile, the most crowded booth was obviously AUO.

The AUO released AMOLED panels are the same ones unveiled at the SID 2014 which are 5.5-inch FHD panel, 5.7-inch WQHD panel, 5-inch flexible AMOLED panel, and 1.6-inch AMOLED panel for smart watch.

AUO manufactures the AMOLED panel in RGB (side by side) method. Despite the recent announcement of mass production plan for 5.7-inch WQHD panel, the mass production scheme of AMOLED panel for the use of mobile is delayed due to yielding issues.

The 1.6-inch AMOLED panel of AUO is produced in small quantity, supplied for ASUS’ smart watch. The resolution is 320×320, 227ppi. According to the person in charge of AMOLED, the AUO is capable of producing thin AMOLED panel less than 0.45mm by applying in-cell touch panel with the technology in its possession.

One thing to notice is that the AMOLED TV was not exhibited. AUO demonstrated the AMOLED panel of ink-jet printing method at SID 2014. About 80 engineers are developing the OLED TV in Gen6 R&D line located at Longtan. The investment stagnates as the growth of OLED TV market slows.

Given the latest concentration on flexible AMOLED team from the OLED researchers of AUO, it is expected that the flexible AMOLED is to be included in the AMOLED investment plan for 2015. There is much attention towards the development of AUO that is a relatively newcomer in AMOLED industry.

2014年 8月 27日/0 コメント/カテゴリ: ディスプレイ, フォーカス・オン /作成者: OLEDNET

At the keynote presentation given at the IMID 2014 held in EXCO, Daegu on the 27^th, Park Dong-geun, the president of Samsung Display announced that the price of display decreases gradually and the color sense, curved design, and flexible display become more important as the technology develops. AMOLED has an excellent color expression for its adobe of 97% compared to 74% of LCD and its outdoor visibility is 1.7 times higher than LCD. Samsung Display highlighted the superiority of AMOLED over LCD with the application of the diamond pixel structure considering the retinal system of human eye, super dimming technology allowing users to use the cellphone in the dark environment without getting any light pollutions, and ultra power saving mode.

Though Samsung Display produced the OLED TV in RGB + FMM method previously, the mass production is currently ceased for the large area yielding issues. The alternative way would be using WOLED + CF method of LG but it takes a long time to mass produce and there is even a patent issue.

Due to the high price of OLED TV, Samsung Display will concentrate its business on the LCD TV for a while. Samsung’s concern for the TV business is expected to grow as the price of LCD will increase as well if applying a new technology like QD.

2014年 8月 21日/0 コメント/カテゴリ: ディスプレイ, フォーカス・オン /作成者: OLEDNET

At the comprehensive workshop of the 9^th Display National R&D Investment Program held on August 20, KH Kim, executive director of Samsung Display stated his view on the future of display for TV.

Kim is expecting that despite many advantages of OLED TV, it is likely to take some time to open a market considering price competitiveness. He also added that accordingly Samsung display will work on developing technologies of color reproduction range, slim and improvement of contrast range for LCD for a while, leading the market and the business will focus on not OLED but LCD in the years ahead.

In the year of 2012, the OLED TV market was dominated by either Samsung or LG, and now only LG is taking vigorous efforts to open OLED TV market. Under this circumstance, the price of the 55inch FHD curved OLED TV has decreased from initial $15,000 to $3,000 but still it is twice more expensive than the 55inch FHD LCD/LED TV, falling behind in price competitiveness.

Who has a key to OLED, JDI or JOLED?

2014年 8月 8日/0 コメント/カテゴリ: ディスプレイ, フォーカス・オン /作成者: OLEDNET

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.

2014年 8月 6日/0 コメント/カテゴリ: ディスプレイ, フォーカス・オン /作成者: OLEDNET

The Innovation Network Corporation of Japan (INCJ), JDI, Sony and Panasonic have finalized an agreement on JOLED establishment by January, 2015 through an integration of OLED panel R&D organizations owned by Sony and Panasonic for mass-production, development and early commercialization of the OLED panel.

INCJ has 75% of JOLED’s voting rights. INCJ and JDI have agreed on making an investment in pilot line installation for mass-production.

JOLED aims to become a leading company in the OLED sector by collecting the technologies owned by Sony and Panasonic such as the OLED layer technology, oxide TFT technology and flexible display technology, and converging with JDI’s mass-production technology.

JOLED plans to develop the OLED panels for application section first, including tablet PC, note PC and signage for mass-production of medium and large size OLED panels. A future target of JOLED is mass-production of the flexible OLED.

LG Display successfully developed world’s first flexible and also transparent OLED.

2014年 7月 10日/0 コメント/カテゴリ: ディスプレイ /作成者: OLEDNET

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.”

The use of OLED is now expected to be extended from interior light and rear lamp to display of automobiles.

According to the display industry, LG Display (LGD) is negotiating with German automakers for plastic OLED panel supply. LGD ranked 4^th in auto display market following Taiwanese Innolux, Japan Display and Sharp of Japan. It aims to take over the global market by reaching 1 billion dollars in sales based on the OLED display by 2016.

Most of major panel makers are currently focusing on leading the auto display market. At SID 2014, the major panel makers including Japan Display, Sharp, AUO and Tianma mainly showed displays for vehicles. LGD also reinforces targeting auto display market by integrating future technologies including transparent display. A fierce competition is ahead among major display companies.

The flexibility and durability; shock- and vibration-resistant, of the OLED as well as the fact that transparent display can be realized with it will accelerate its entry to the auto display market.

For auto rear lamp and interior light, the major OLED lighting panel makers including LG Chem. and Osram are developing the OLED and a new market is within the reach. If the OLED rapidly forms the auto display market, it will become a great cornerstone of the OLED industry along with mobile, TV and general lighting.
