From the press release:
Ciba has developed a deep red phosphorescent OLED emitter that functions optimally in combination with the Novaled PIN OLED™ technology, delivering a lifetime of 50,000 hours at an initial brightness of 1,000 cd/m2. The new material supports the market trend toward high-performance, low-voltage OLED devices for display and lighting applications.
“We want to provide the market with efficient phosphorescent materials,” says Rolf Drewes, Global Head of Business Line Electronic Materials at Ciba. “In this project, we are developing the full color range of emitters compatible with Novaled’s proprietary OLED technology. Our deep red, the first to become commercially available, offers customers not only long-lifetime performance but also excellent thermal stability. Green and blue are now in progress.”
“Phosphorescent emitter materials together with low-voltage devices are mandatory for the future of the OLED industry, and Novaled is very pleased to see a key industry player developing such materials,” adds Gildas Sorin, CEO of Novaled AG. “This deep red phosphorescent material provides a long lifetime at a lowest operating voltage of 3.3 V as well as good power efficiency of 8.1 lm/W, making it suitable for displays as well as for completely new lighting applications. OLED technology even has potential to surpass the efficiency of energy-saving bulbs.” […]
In 2006, Ciba and Novaled entered an industrial collaboration to create organic dopant and transport materials for the Novaled PIN OLED™ technology, which enables highly power-efficient OLED performance.

Under the merger agreement, Sumitomo Chemical will acquire all outstanding shares of CDT common stock at a price of $12 per share in cash, for an aggregate purchase price of approximately $285 million. The merger consideration represents a 107 percent premium over CDT’s 90-day average closing share price and a 95 percent premium over CDT’s closing share price of $6.15 on July 30.
According to DigiTimes, Chi Mei EL Corporation (CMEL), a Chi Mei Optoelectronics (CMO) subsidiary,
started [to] volume produce active-matrix (AM) OLED (organic light-emitting diode) panels in May, with monthly capacity able to reach 500,000 2-inch equivalent panels at present.
Zhe-yang Chen, president of CMEL, said the company has begun shipping 2-inch AM OLED panels to China- and Japan-based customers and end products adopting CMEL’s panels will hit the market in July at soonest. […]
The company now sees related yields at 60%, which will be improved to 80% by year-end, said Chen. Achieving high yields in the AM OLED industry is not easy; even leading makers such as Samsung SDI only targets yields at 60-70% initially, he pointed out. […]
Prices for an AM OLED panels now are still 1.8 times higher than those for the same-size TFT LCD panels. The company expects to see the price gap between the two segments narrow to 1.5 times in the future, according to Chen.
The 2.5-inch prototype display supports 16.8 million colors at a 120 x 160 pixel resolution (80 ppi, .318-mm pixel pitch), is 0.3 mm thick and weighs 1.5 grams without the driver.
The prototype, as well as technical details were presented at the SID conferernce. Apparently the display is driven by pentacene TFTs with a mobility of 0.1 cm2/Vs.
Each subpixel (red, green or blue)is driven by a two-transistor, one-capacitor PMOS voltage programming circuit. The display operates at a frame rate of 60 Hz with a signal voltage of 12 V.
Sony uses a top-emission structure for its OLED displays, meaning they have driving transistors on the bottom and emit light from a top OLED layer. […] The structure reportedly allowed the engineers to fabricate the electrodes before fabricating the organic TFT layer, without damaging the semiconductor layer.
The latter is achieved by depositing the pentacene on a patterned, negatively-sloped layer acting as a “built-in shadow mask”.
According to Reuters, Sony are planning to be the first to bring OLED TVs to the Market later this year.
At a display forum in Tokyo, customers, suppliers, and even rival TV makers turned their backs on 50-inch and bigger TVs to throng before Sony’s tiny 11-inch OLED TVs.
“LCD and plasma displays look faded in comparison,” said a Denso Corp. employee who declined to be named, fighting to take a picture of the new TVs. […]
The OLED TV to be launched this year will be made by ST Liquid Crystal Display Corp., a joint venture between Sony and Toyota Industries Corp., Sony spokesperson Daiichi Yamafuji said, declining to give unit targets or a likely price. […]
The Nikkei business daily reported earlier that Sony would begin by mass-producing about 1,000 of the 11-inch OLED sets a month?a fraction of its LCD TV business?and would aim to keep its price within a few times that of existing flat TVs. […]
Other companies investing in OLED displays include Seiko Epson, Canon, Samsung and a joint venture between Toshiba and Matsushita Electric Industrial Co..
Toshiba President Atsutoshi Nishida said on Thursday the company hoped to make larger TV-use OLED panels at the joint venture, Toshiba Matsushita Display Technology Co., by 2009, taking aim at the $35 billion flat TV market, which is currently dominated by LCD and plasma display technology.
Japan’s Dai Nippon Printing (DNP) will commercialize OLED (organic light-emitting diode) panels before the end of fiscal year 2008, according to the company.
Jointly with a research institute, the Japanese vendor plans to develop technology to extend the lifespan of panels by ten times that of conventional products to 10,000 hours, with a brightness at 1,000 cd/m2, the company said.
The maker will start by offering light-emitting sign displays and aims to proceed with development of traffic advertisement applications, DNP noted.
Konica Minolta (KM) and General Electric (GE) announced
a strategic alliance agreement to accelerate the development and commercialization of OLED (Organic Light Emitting Diode) devices for lighting applications. The goal is to bring OLED lighting to market within the next 3 years. […]
On June 30, 2006, KM announced that it had successfully developed a white OLED with a world record power efficiency of 64 lumens per watt at 1,000 candela per square meter — a brightness which is appropriate for lighting applications. Prior to this development, KM developed its own highly efficient and long-life blue phosphorescent materials. Applying these material technologies, along with multi-layer design technology and innovative optical design technology, KM succeeded in developing an OLED having a practical light emission level of approximately 10,000 hours.
In addition to material technology and optical design technology, KM has been developing the ultra-high barrier film fabrication technology to enable high productivity. Superb coating technology nurtured through the development of photographic film and display materials also plays an important role in the development of highly productive OLEDs. Currently, research and development for its commercialization is under way.
GE, as part of its ecomagination initiative, has made substantial investments in OLED research that has resulted in world records for OLED lighting device size and efficiency. In 2004, researchers were able to demonstrate an OLED device that was fully functional as a 24 inch by 24-inch panel, which produced 1,200 lumens of light with an efficiency on par with today’s incandescent bulb technology. This was the first demonstration that OLED technology could potentially be used for lighting applications. Since then, GE has more than doubled the level of OLED efficiency using device architectures that are scalable to a large area and can be produced cost-effectively.
In addition to increasing efficiency, GE has focused on developing all the requirements - ranging from plastic film substrates, ultra-high barrier coatings, and fabrication processes and equipment to enable the high speed, cost-effective “roll-to-roll†manufacturing — required to produce large-area OLED lighting.
the market for OLEDs used in displays and lighting applications is expected to reach $10.9 billion ($US) by 2012 and grow to $15.5 billion by the year 2014.
The report discusses the use of OLEDs for mobile devices, flexible/rollable displays, and lighting applications.

MicroEmissive Displays (makers of P-OLED microdisplays) announced that
the PDG – Personal Display Glasses, the world’s first mobile TV viewing experience employing the MDDI standard, is on display at 3GSM 2007 in Barcelona from 12 – 15th February.
The PDG is the most advanced integrated personal display and mobile phone solution on the market. The PDG has been developed by Mobintech A/S from Denmark and is enabled by ultra-low power P-OLED eyescreenâ„¢ microdisplays from MicroEmissive Displays.
According to their press release, MicroEmissive Displays (MED, Edinburgh, UK)
will start commissioning and qualification of its new production plant in the Fraunhofer IPMS in Dresden early in 2007. The move comes following the on-time handover of the purpose built cleanroom and delivery of the tool set from ANS Korea.
The 350 m2 purpose built cleanroom is state of the art and is located within the substantial facilities of the Fraunhofer IPMS campus. Construction of the cleanroom was completed on time; equipment is in place and installation is already underway. The tool set, delivered from ANS Korea in December, comprises polymer OLED based deposition and thin film
encapsulation equipment for mass production.
it has received a £2m order for its new polymer-OLED eyescreen™ microdisplay. The order, from a manufacturer of consumer products in the Far East, will also be the first to ship from the company’s new manufacturing facility in Dresden.
The order relates to MED’s new eyescreenâ„¢ ME3204 microdisplay. The new device is a compact 6 mm (0.24â€) colour P-OLED QVGA display. The P-OLED technology is emissive and so does not require a backlight; as a result eyescreenâ„¢ ME3204 is ideal for portable applications such as video glasses or head-mounted displays, electronic view finders and night vision systems. The microdisplay can be combined with magnifying optics to produce a large virtual image that appears to the eye to be equivalent in dimensions to the picture on a TV screen or computer display.
In addition eyescreenâ„¢ ME3204 features a digital video interface together with an integrated display driver eliminating the need for additional driver ICs. This design feature saves space and reduces both power consumption and BoM costs.
that it is able to produce thin film encapsulated OLED devices that meet the shelf-life requirements for commercial use. Not only are these displays manufactured on OTB’s in-line mass manufacturing equipment, but also the deposition of the thin film encapsulation has been proven to render the same optical performance as the conventional, more expensive glass-can encapsulated devices. […]
Bas van Rens, CEO of OTB Display, explains: “Our integrated in-line mass manufacturing equipment now routinely produces displays which pass the accelerated shelf life of 504 hrs at 60oC / 90% humidity. In our development program we observe rapid progress and we expect to be able to announce shelf lifes exceeding 1000 hours at 85 oC/ 85% this year”
The two displays, bevels included, were just 5mm thick.
The first display is a compact, 11in model with a native resolution of 1,024 x 600. [..] It uses eight-bit per channel RGB colour and offers a contrast ratio greater than a million-to-one contrast. Its all-white brightness is 200cdm², peaking at more than 600cdm²
The second display is a larger model. With a resolution of 1,920 x 1,080, the 27in, 16:9 panel will be capable of displaying a 1080 HD image. The bigger screen has the same contrast and brightness as the small model, but it can display colurs defined using ten bits per channel.
Both screens are based on what Sony calls its ‘Super Top Emission’ technology.
an anthracene derivative containing free positive ions and a ruthenium, complex containing negative ions. When the two are joined, ions diffuse across the junction creating a difference in energy levels that facilitates rectification, electroluminiscence and photovoltaic response.
The technique is potentially suitable for low-cost fabrication of flexible photovoltaics and LEDs.
has updated its 2006 OLED Technology Report, a comprehensive examination of the fledgling OLED industry, which reached revenues of $491M in 2005, up 8% Y/Y, and unit shipments of 55.8M, up 72%. Updates are due to a number of recent changes affecting the OLED industry:
* Liquidation of SK Display
* TMDisplay and Seiko Epson de-emphasizing commercialization of AMOLEDs
* Pioneer closing its ELDis JV and the concurrent end of its AMOLED activity
* Sharp reduction in small/medium panel ASPs due to over capacity in TFT LCDs
* Continuing difficulty in using LTPS backplanes for AMOLEDs
One of the unique features of the report is a forecast of the OLED capacity as shown in Table 2 by active, passive, SM and P-OLED technology and the associated organic material usage in weight and in revenue, differentiated by emitting and conducting layers for both small molecule and P-OLEDs. The organic material is forecast to grow from $220M in 2005 to $549M in 2010, driven by the increased capacity of the AMOLED display makers.
*Includes material used in production and R&D facilities for 2” displays
are paving the way for the production of a new generation of high resolution polymer organic light emitting displays (P-OLED) through the development of an inkjet printing solution capable of producing P-OLED displays at up to 200 pixels per inch (ppi).
