Qualcomm
 Established in 1985 in San Diego, CA.
 Co-Founded by Dr. Irwin Jacobs
 Qualcomm is the global leader for developing and
delivering ground-breaking products and solutions.
What Is Mirasol?
 The next generation of flat panel displays
 Inspired by the butterfly’s wings
Key Words
 Biomimetics: The study of the structure and
function of biological systems as models for the
design and engineering of materials and machines.
 IMOD Technology: A new approach based on LCD
technology.
 MEMS, Micro-Electro-Mechanical System:
The integration of mechanical structures with
microelectronics.
Features
 Ultra-low power consumption  longer battery life
 Superior Viewability  works in all lighting, even in the sun
 Enhanced Readability  reduces eye fatigue
 Robust Functionality  virtually not affected by the environment
 Mechanical Durability  long operational life
 Technical Compatibility  easy integration and adoption
 Technical Flexibility  wide design and implementation options
Inspired By Butterfly’s Wings
 Butterfly wings reflect light in a way that specific
wavelengths interfere with each other, which create
nature’s most vivid colors.
 By using this premise as the starting point for the
new IMOD technology, Qualcomm mimics this
nature of light in a new cutting-edge display
technology, Mirasol.
How Mirasol Works
 Pixel elements consist of simple, tiny micro-electro-
mechanical systems (MEMS) comprised of two conductive
plates: a thin film stack on glass substrate and a reflective
membrane suspended below.
 When bias voltage holds the reflective membrane in the open
state, the subpixel reflects a specific color.
 When applied voltage collapses the reflective membrane, all
visible light is absorbed, making the element black.
 To create a flat-panel display, many elements are grouped
together as pixels or subpixels. Varying voltage across the
display’s elements creates rich, detailed imagery.
Efficiency of Mirasol Memory
 Mirasol’s MEMS is called hysteresis.
 Hysteresis allows it to maintain its state (open or
collapsed)
 Once in its state, it stays there with very low
quiescent current.

This means that the display acts as a extremely power-efficient
memory element, providing remarkable power savings over
active matrix devices that continually refresh.
