Description:

Area of Interest 4: High efficiency, low-voltage,
stable materials for
OLED-based general illumination technology (hosts, dopants, and transport
layers)

Today, OLEDs designed for general illumination purposes may be derived from

those normally associated with display applications. This is not ideal as
general illumination OLEDs have unique price and performance requirements
that
will allow them to perform as viable alternatives to conventional luminous
sources. To evolve into this new performance domain, applied research in
novel
materials hosts, alternative dopants, and advancing a more comprehensive
understanding of the role and design rules for charge transport in layers
is
sought.

Current OLED materials simply do not have the efficiency or lifetime
performance necessary to qualify them as viable candidates for the
demanding
general illumination market. Estimates of lifetime and efficiencies
necessary
for OLED based general illumination are roughly 50,000 hours and 100
lumens/Watt respectively. Lifetime and efficiency of state-of-the-art
white
OLEDs (at 850 cd/m2) are about 500 hours and 5 lumens/Watt respectively.
To
realize the full potential of OLED technology, new materials and systems
are
needed that offer the promise of vastly improved efficiency and stability
in
the active regions of the OLED device- cathode and anode layers, electron
and
hole transport and injection layers, emission layers, and carrier blocking
layers. New phosphorescent OLED systems with nearly 100% internal quantum
efficiency at high current densities are required in the red, green, and
blue
spectral regions. Single molecules that produce a broadband emission and
that
harvest triplet energies otherwise lost as heat are also needed.
Innovative
device structures and materials are needed to reduce high-luminance (~1000
cd/m2) drive voltages from 10-20V to 4-5V. Compatibility with practical
methods of current distribution and controls must be assured.

This topic specifically addresses the development of novel materials that
might
be used to create high efficiency, low voltage, stable OLEDs with improved
internal quantum efficiency (IQE). Novel methods of extracting light or
alternative light management approaches that produce higher external
quantum
efficiency (EQE) from existing materials systems and structures are south
under
Area of Interest 5. Likewise, novel device designs that may produce
increases
in IQE and EQE are sought under another Area of Interest 6.
