QDs operate in two modes
Photoluminesence (PL mode)
Activated by light energy
Conversion of color from
other light sources
Any light with shorter wavelength
(higher energy)
Electroluminescence (EL mode)
Activated by electronic energy
Direct emission of colored light
Requires charge transfer films
“QLEDs”

QLED Microdisplays
(SVGA, 15 mm diagonal)
Why QLED?
Power efficiency
directly translates
to SWaP reduction.
Color purity and
tunability allows
for better selection
for nighttime use,
scotopic response.
APEC 2-09-12 14
Transparent QLEDs
Why QLED?
Transparent device
importance of optical
stack, secondary optics.
Monochrome QLED
spectrum results in less
chromatic aberration
through secondary
optics, simpler refraction.
APEC 2-09-12 15
Infrared QLEDs
Why QLED?
No wasted photons as all
generated light is in
infrared (without filters).
Currently tunable through
NIR and SWIR.
Only efficient, large area
IR emitter technology.
