TMDisplay develops 2.2" OLED with world's longest lifetime and best efficiency

oled — Wed, 20 Aug 2008 01:45:28 -0400

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").

Utah researchers: OLEDs will not be as efficient as previously thought

oled — Mon, 18 Aug 2008 01:33:28 -0400

University of Utah physicists suggest it will be more difficult than thought to make highly efficient light-emitting diodes (LEDs) using organic materials. The findings hint such LEDs would convert no more than 25 percent of electricity into light rather than heat, contrary to earlier estimates of up to 63 percent.

UDC Awarded $1.9 Million U.S. Department of Energy Contract to Accelerate Development of White OLED Lighting Products

oled — Thu, 24 Jul 2008 00:22:12 -0400

Universal Display Corporation today announced a $1,918,878, two-year U.S. Department of Energy (DOE) contract to develop a ceiling-based white OLED lighting system. Universal Display plans to use Armstrong World Industries as a key subcontractor to fulfill the requirements of the grant. Funded through the U.S. DOE Office of Energy Efficiency and Renewable Energy, this Solid-State Lighting (SSL) Program award supports the DOE’s long-term commitment to advance the development and market introduction of energy-efficient, solid-state white light sources for general illumination.

During this SSL Product Development Project, Universal Display and its subcontractor, Armstrong, will develop and deliver an integrated ceiling illumination system that is targeted to exceed the DOE’s 2010 performance goals. The white OLED lighting panels will be designed and fabricated by Universal Display using its high-efficiency phosphorescent OLED technology. The panels will then be integrated by Armstrong into its innovative TechZone™ open-architecture ceiling system. In addition, the team will deliver a white OLED lighting panel fabricated on a thin metallic foil substrate using Universal Display’s UniversalPHOLED and other OLED technologies, to demonstrate the commercial product potential of white OLEDs with a flexible form factor.

Researchers use a tandem system of grids and micro lenses on white OLED for efficiency

White OLEDs are already producing more light per watt than incandescent bulbs, according to engineering professor Stephen Forrest from Michigen University, but it is trapped inside the device. By fabricating a tandem system of grids and micro lenses on a white OLED, the device can achieve a brightness of over 70 lumens per watt, compared with 15 lumens for incandescent bulbs--almost as much as fluorescent tube lights (90 lumens).

Japanese government and companies team up to develop OLED tech

oled — Thu, 10 Jul 2008 02:12:08 -0400

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.

Kodak OLED Systems Information and Interview

I recently had the chance to interview Mr. Corey Hewitt and Dr. James Buntaine from Kodak OLED Systems. Kodak is where OLEDs were first discovered, and they are still in the fore-front of the technology. This is going to be a long article - these guys have given me a lot of background info, even before answering my questions. But first let's introduce Corey and James:

OLED100.eu - a new EU OLED white light project to follow-up on OLLA, gets 30M$ funding
