Qualcomm’s Mirasol
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.
