Pacific Northwest National Laboratory announced a new host materials
for a blue phosphorescent OLED boost efficiency by at least 25 percent
and help solve "weakest link" in development of cost-effective white OLEDs.
The weakest link in OLED research is the absence of an efficient,
long-lasting blue light to accompany the red and green," said Pacific
Northwest National Laboratory scientist Asanga Padmaperuma. Development
of better host materials to manage the flow of electricity through the
device could help solve that problem.
Padmaperuma and his collegues have designed, synthesized and tested
new materials that improve the power efficiency of blue OLEDs by at
least 25 percent.
The most promising technology is the organic light-emitting diode,
or OLED. These multi-layered devices produce light by running an
electrical current through a specially engineered host material into
which light-producing phosphorescent molecules are embedded or "doped."
The white light envisioned for large-scale applications, such as rooms
and buildings, consists of red, green and blue light.

OLED Lighting to Take Off in 2011; Revenues Will Pass PMOLED
Displays by 2014, Reaching $6 Billion by 2018, DisplaySearch Predicts
Sort Date: 03122009
AUSTIN, TEXAS, March 12, 2009—TheOLED
lighting market is setting the stage to take off in 2011, with OLED
lighting revenues forecasted to surpass PMOLED displays in the
2013/2014 timeframe, reaching $6 billion by 2018, according to
DisplaySearch’s newly-released report, OLED Lighting in 2009 and Beyond: The Bright Future.
“The unique features of OLED lighting are inspiring the imagination
of designers. OLED lighting devices emit from the surface, can be made
flexible/rollable, and even transparent like a window or reflective
like a mirror. OLED lighting is thin, rugged, lightweight, and has fast
switch-on times, wide operating temperatures, no noise and is
environmentally friendly. The power efficiency of OLED lighting has
also improved dramatically in recent years,” said Jennifer Colegrove, PhD, Director of Display Technologies at DisplaySearch.
“Hundreds of millions of dollars have been invested in OLED
lighting, especially in Europe, the US, and Japan. Although OLED
displays have been in mass production for about a decade, OLED lighting
just started sampling and small volume production. This is due to the
fact that OLED displays and OLED lighting face different challenges,”
added Dr. Colegrove.
Market size, in both area (m2) and revenue ($) are
forecast through 2018, with breakdowns for six applications, including
automotive, display backlights, decorative/general lighting,
healthcare/industrial, and signage/advertisement. Market forecasts are
also given by substrate type, detailed by flexible versus rigid.
Looking into the future, the OLED lighting industry will pick up in
2011, with Philips, GE, Konica Minolta, Lumiotec and OSRAM entering
mass production (Figure 1).

In OLED Lighting in 2009 and Beyond,
DisplaySearch analyzes trends in the lighting industry and compares
OLED lighting with five other lighting technologies: incandescent,
fluorescent, high intensity discharge, LED and electroluminescent (EL).
The report covers the OLED lighting supply chain, including more than
130 companies and universities, and analyzes several organizations
related to OLED lighting in Europe, the US, Japan, Korea, Taiwan and
China. The report also forecasts the efficiency, lifetime, and average
selling price of OLED lighting devices. The OLED lighting and OLED
display markets are compared and the market forecasts are analyzed.
Business strategy recommendations are also given in the report.
Finally, OLED lighting technologies, including structures, materials,
efficiency improvement techniques, lifetime trends, and manufacturing
(roll-to-roll vs. batch), are discussed and analyzed.
OLED Lighting in 2009 and Beyond: The Bright Future is delivered in PowerPoint and Excel file. For more information, contact Carl Holec at +1.512.687.1505 or sales@displaysearch.com or contact your regional DisplaySearch office in China, Europe, Japan, Korea or Taiwan.
