QD Vision’s Focused & Integrated Approach

The only quantum dot company focused solely on displays & lighting

The 1st quantum dot company to market in lighting

Founded in May 2005 - MIT roots

74+ employees - R&D

transitioning to operational focus

Moved into new 59k ft2 facility

IP from MIT license, Motorola

patent acquisition, and QDV filings

VC funded, ~$55M raised to date

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”

• Wide-color gamut

• No need for color filters

• No need for microcavities

• Low-voltage driving

• Highest lumen/photon

• No backlight or color filters

• Printable Layers

• Simpler BOM

Excellent color purity

Low power consumption

Simple construction

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.

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.

Page 15: QD Vision’s Focused & Integrated Approach

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.
