Quantum Dot Solutions for Lighting and Display Applications Frank Ignazzitto APEC Conference February 9, 2012
QD Vision s Focused & Integrated Approach The only quantum dot company focused solely on displays & lighting Founded in May 2005 - MIT roots 74+ employees - R&D transitioning to operational focus Moved into new 59k ft 2 facility IP from MIT license, Motorola patent acquisition, and QDV filings VC funded, ~$55M raised to date The 1 st quantum dot company to market in lighting 2
Emission Intensity, a.u. Quantum Dot Semiconductor Nanocrystals A practical solution to deliver light with extraordinary color & efficiency Core Color is controlled by size as well as composition Shell Power efficiency & stability Semiconductor Nanocrystal 2-12 nm Caps Process economics & design flexibility 400 500 600 700 Wavelength, nm 3
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 4

QLED Microdisplays Why QLED? Power efficiency directly translates to SWaP reduction. Color purity and tunability allows for better selection for nighttime use, scotopic response. (SVGA, 15 mm diagonal) 13
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. 14
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. 15
QD Vision Summary Revolutionary technology Extensive patent portfolio World class team Practical, integrated solutions Mission-critical focus Top tier partners 16
