Area of Interest 5: Strategies for improved light
extraction and manipulation

Significant advancements in OLED device performance will require applied
research leading to alternative strategies for light extraction and optical

management. Conventional limits on OLED out coupling efficiency is
exceptionally low producing damaging heat instead of useful photonic
emissions. Research in this area could include advanced modeling or
exploration of novel geometries that promise to achieve 50% or more light
extraction efficiency.

Current light out-coupling efficiencies are on the order of 20%.
Innovative
approaches utilizing surface texturing, gratings, periodic nanostructures,
integrated lens or device shaping are necessary to increase the
out-coupling
efficiency to the desired level of >50%. Even the basic configurations
and
accepted practice of layering OLED structures may need to be reexamined to
ascertain if the ideal geometry is possible. Other novel methods to
increase
device extraction efficiency like designing for some level of cavity
resonance
or mode structure may hold promise. With the internal quantum efficiency
of
basic OLED materials systems already approaching 90%, significant
advancements
in light extraction efficiency or external quantum efficiency (EQE) holds
considerable promise. Applications to this Area of Interest may be
theoretical, modeling oriented or experimental but all should represent
novel
approaches that offer the potential for large increases in performance, not

just incremental increases in EQE.

This Area of Interest is restricted to applied research that promises a
breakthrough in external quantum efficiency (EQE) commensurate with the
criteria provided above. Proposals that address small, incremental
increases
in EQE are not of interest. Proposals representing increases in materials
IQE
are sought under Area of Interest 4 and proposals for novel device
structures
and materials systems are sought under Areas of Interest 6.
