Plextronics Says Their Printable Ink Improves Performance in PLEDs

GE research team pulls together an OLED christmas tree
The research team at GE has put together a cool OLED christmas tree. The OLEDs were made by a roll-to-roll fabrication. The OLED is 6 inch wide, by 15 feet. Here's a nice video of the tree:
Anit Duggal, who's leading GE OLED program said - We’re making great progress toward hitting the metrics needed to successfully introduce OLED lighting to market. We continue to make steady advances in efficiency, lifetime, and lighting-quality using device structures that can be made with roll-to-roll manufacturing, so that we’ll be able to introduce OLED lighting at an affordable price.
We also got a nice high resolution picture of the tree:
BASF and OSRAM developed a 60 lm/W all-phosphorescent OLED lighting panel
BASF and Osram Opto Semiconductors have developed a highly efficient white OLED panel. The efficiency is over 60 lm/w. This development was part of the OPAL project which launched in 2008. Other partners in this project include Aixtron, Philips and Applied Materials.
South Korean scientists say they developed efficient true-blue OLED
Jin Sung-Ho, a chemistry professor at Pusan National Univeristy in South Korea, say they have succeeded in devloping efficient true-blue OLED materials. The project was state funded, together with Seoul National University.
New Kodak Green Boosts OLED Performance and Energy Efficiency
Eastman Kodak today announced the introduction of a highly efficient OLED material that will enable low-power, full-color displays
with outstanding lifetimes. The new material, trademarked KODAK OLED
Material EK-GD403, utilizes green dopant technology to deliver a new
level of OLED display performance and reliability.
Green dopants are materials that control color output and boost
efficiency.
"Kodak has continued to make greater than 50
percent year-over-year improvements in OLED luminance efficiencies over
the past few years, and we will continue to fill the pipeline with new
innovation to ensure that Kodak OLED materials are ready for use in
emerging large-market applications," said
Corey Hewitt, Operations Manager and Vice President, Kodak OLED Systems (we had an interview with Corey a few months ago).
KODAK OLED Material EK-GD403, used in combination with Kodak OLED
Material EK-BH109, provides low-voltage green OLEDs with luminous
efficiencies greater than 31 cd/A and lifetimes in excess of 65,000
hours (from an initial luminance of 1,000 cd/m(2)
and results in an external quantum efficiency of 8.7%.
New Report : OLED Backlighting Market Will Reach $1.1 Billion By 2015
This report analyzes and forecasts the rapidly emerging market for OLED lighting and answers important questions on which segments of the lighting market will see the first penetration of OLED lighting and when and what are the likely improvements that we will see in lifetimes, luminance and efficiency over the coming years.
Key findings:
- The unit costs of OLED lights are likely to remain higher than older general lighting technologies but the extra costs will be offset by improved OLED lifetimes and efficiencies. During 2008, OLED lifetimes improved from 24 Khrs to 100 Khrs. Meanwhile, the U.S. Department of Energy now expects OLED lighting to reach 150 lm/W efficiency in 2012 rather than 2014 as previously forecast. NanoMarkets believes that these and other improvements in OLEDs will drive the general illumination market to $2.3 billion in revenues by 2015.
- Manufacturing processes for OLEDs have also progressed significantly. GE and the Fraunhofer Institute have both demonstrated roll-to-roll manufacturing of OLED lighting which will ultimately lead to significant cost improvements in OLED fabrication. Low cost printing approaches and new small molecule inks will also help propel OLEDs into the backlighting market. NanoMarkets expects that the OLED backlighting market will reach $1.1 billion by 2015. And while the first OLED lighting panels are quite small, the recent scaling up of factories in Asia to build large OLED displays will certainly benefit the manufacturing infrastructure for OLED lighting and lead to larger panels within a few years.
- The flat and flexible format presented by OLEDs creates an opportunity to design high-value added lighting fixtures with an appeal to upscale consumers and especially architects. During 2008, lighting designer Ingo Maurer introduced the world's first OLED "function table light" and researchers at GE are targeting lighted curtains and lighted wallpaper. By 2015, NanoMarkets projects that sales of OLED architectural and specialist industrial lighting will reach $1.9 billion
Ingo Maurer - we hope to start delivering our OLED lamp this month. Oh, and we'll make only 25 of them
Ingo Maurer, who designed Early Future - the beautiful OLED lamp using OSRAM OLED panels, says he hopes the first two lamps will be deliveres this month.
In total, they will only make 25 of them, which are probably very expensive and not very practical - as the the light is reportedly rather dim and the panels have only 2,000 hours lifetime (D50).
TMDisplay develops 2.2" OLED with world's longest lifetime and best efficiency
TMDisplay (JV between Matsushita and Toshiba) says it developed an OLED panel with the world's longest lifetime and best efficiency. The 2.2-inch OLED panel has a lifetime of 60,000 hours and power consumption of 100 mW.
TMDisplay has developed the new panel in cooperation with Idemitsu Kosan, a Japanese oil refiner active in OLED materials development. They say they aim to start commercial production of the advanced OLED panels by March 2009 for cellphones and other mobile devices. It has yet to decide the size of production. Previous reports say that TMDisplay will invest 140M$ on OLED production, and that they set their monthly output of 1.5M units a month (at 2.5").
Japanese government and companies team up to develop OLED tech
The Japanese government will team up with several Japanese companies to develop key-technologies for producing large-size OLED panels. The aim is to cut the development cost for the Japanese companies, to be better able to compete against Samsung and LG, and the Japanese government will pitch in around 32$M.
The project will also try to make the displays more efficient and have longer lifetime.
One report says the project will run till 2013, another that it will run until 2015, and the aim is to produce 40" OLED TVs by then. We'll have to wait and see...
The companies include -
- Sony
- Toshiba
- Matsushita
- Sharp
- Idemitsu Kosan
- Sumitomo chemical
- Dainippon Screen Mfg
- Shimadzu
- Hitachi
Interesting to see Sharp in there, after having stated that "OLEDs will not threat LCD for at least a decade".
CombOLED - A New EU Project For Cost Effective OLED Mass Production
OSRAM Opto Semiconductors is spearheading the effort to develop cost-effective volume production methods for organic light emitting diodes (OLEDs) under the CombOLED project, a European funded research and development project that was conceived to combine new device structures, advantageous manufacturing approaches and less complex materials with the aim to achieve cost effective OLED lighting solutions.
The objective of the CombOLED project, which is being funded by the EU and coordinated by OSRAM, is to create the necessary conditions for introducing the new light sources into lighting applications, said Bernhard Stapp, Head of Solid State Lighting at OSRAM Opto Semiconductors. This includes methods for cost-effective printing of new component architectures for large-format transparent light sources. As an innovation driver in the LED market and a pioneer in the mass production of semiconductor components, OSRAM Opto Semiconductors is bringing valuable know-how to the EU project.
