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

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.
