EWING, N.J.--(BUSINESS WIRE)--
Display Corporation (Nasdaq: OLED), enabling energy-efficient
displays and lighting with its UniversalPHOLED®
technology and materials, today announced OLED technology and material
advancements, which include a novel display architecture and a new
approach for color tunable phosphorescent white OLED lighting. These
advances were highlighted by Universal Display scientists in three
separate papers presented earlier today during the 2014
Society for Information Display (SID) International Symposium, Seminar,
In an invited paper titled “Color Tunable Phosphorescent White-OLED
Lighting Panel”, Universal Display’s Dr. Michael Weaver presented data
on a new approach of fabricating red-green-blue (RGB) monochrome stripes
and controlling each of the stripes with separate current drivers. This
new method has the potential to improve white OLED lighting panel
performance, manufacturing yield, brightness uniformity and color
tunability. The latter is a key benefit of solid-state OLED lighting.
The paper was co-authored by Dr. Xin Xu, Dr. Huiqing Pang, Dr. Ruiqing
Ma, Dr. Pierre-Luc Boudreault, Dr. Alex Dyatkin, Dr. Sean Xia and Dr.
Julie Brown and Acuity Brands’ Dr. Min-Hao Lu.
In this paper, Dr. Weaver discussed the recent demonstration of a 15 cm
x 15 cm color tunable white OLED lighting panel based on an RGB
monochrome striped architecture. Using this new architecture, a panel
efficacy of 63 lumens per Watt (lm/W) with a correlated color
temperature (CCT) of 3,000K at 2,500 cd/m2 was achieved.
Additionally, the company has demonstrated an Energy Star
all-phosphorescent warm white OLED with 100 lm/W power efficacy and an
LT70 lifetime of 60,000 hours at 1,000 cd/m2. Dr. Weaver also
reported a remarkable high R9 warm white WOLED with CRI R9 of 96.
By improving white OLED lighting device performance and tunability,
Universal Display’s PHOLED technology and materials have the potential
to meet growing demand for tunable white OLED lighting products. A
number of UDC’s customers have already previewed these new materials for
use in tunable white OLED lighting applications.
Dr. Mike Hack also presented a paper today titled “Novel Two-Mask AMOLED
Display Architecture”. In the paper, Dr. Hack discussed the pathway for
a significant improvement in the lifetime of an OLED display (by as much
as 8 times) using a new display architecture that could enhance blue
lifetime, thus significantly reducing image sticking. This new AMOLED
display architecture may also improve the manufacturability of AMOLED
displays, particularly large-area TVs, as well as increase AMOLED
display resolution and lifetime, and further reduce device power
consumption. The paper was co-authored by Dr. Michael S. Weaver, Dr.
Woo-Young So and Dr. Julie Brown.
Dr. Hitoshi Yamamoto presented a paper titled “Understanding Extrinsic
Degradation in Phosphorescent OLEDs”. In his presentation, Dr. Yamamoto
discussed some fundamental results of improving overall PHOLED device
technology performance. This work was to study the impact of process
conditions during OLED device fabrication. As reported, this study shows
that by reducing the existence of impurities, such as water, during
fabrication, the device lifetime can be significantly enhanced. The
paper was co-authored by Dr. Michael S. Weaver, Dr. Julie Brown, Japan
Advanced Institute of Science and Technology’s Professor Hideyuki Murata
and Kyushu University’s Professor Chihaya Adachi.
Additionally, on Tuesday, Bhadri Visweswaran presented a joint symposium
paper by Princeton University and Universal Display Corporation titled
“Predicting the Lifetime of Flexible Permeation Barrier Layers for OLED
Displays”. The paper was co-authored by Siddharth Harikrishna Mohan, Dr.
Prashant Mandlik, Jeff Silvernail, Dr. Ruiqing Ma, Dr. Julie Brown,
Professor James Sturm and Professor Sigurd Wagner. This paper presents
results of a water diffusion study through Universal Display’s
single-layer barrier encapsulation technology measured with Secondary
Ion Mass Spectrometry, electrical capacitance, and mechanical film
stress. The time taken for one monolayer of water molecules to permeate
into the OLED is defined as the package lifetime. Using this model, it
is predicted that a 3 micron thick layer of the company’s single layer
barrier may have a package lifetime of > 10 years.
“Universal Display is constantly developing and evaluating new methods
to support our customers,” said Steven V. Abramson, President and Chief
Executive Officer of Universal Display. “Our work goes well beyond
