Microvision, Inc., a global leader in innovative ultra-miniature projection display and image capture products for mobile devices, today announced that it has received external validation of key shock-resistance susceptibility performance for its wide angle (WVGA) MEMS scanning mirror, a key component inside the company's ultra-miniature PicoP display engine. Testing was conducted by Fraunhofer Institute for Photonic Microsystems (Fraunhofer IPMS). Fraunhofer IPMS is an internationally recognized research and development institute for MEMS.
According to Sid Madhavan, Microvision Vice President of Research and Development, “Key components reliability testing is part of our commercial development process. I’m pleased to confirm that our newest generation MEMS scanner has been successfully tested externally and the results are very promising. Our MEMS scanning mirror exceeds twice the shock performance requirements provided by Original Equipment Manufacturer (OEM) partners. This means that when our MEMS scanning mirror is embedded in a typical hand held device it will exceed the required shock orientations of a 4 foot drop test on concrete in all shock orientations.”
“Long-term shock and drop reliability of MEMS is extremely important for any devices that will be handled by consumers on a daily basis and manufactured in very large quantities,” stated Dr. Harald Schenk, deputy director and head of the Micro Scanner Devices business unit Fraunhofer IPMS. “With Microvision’s MEMS device we’ve performed extensive shock testing. Our results confirmed that Microvision’s devices exceed the shock resistance specifications for consumer electronics hand-set manufacturers by twice the defined requirements.”
Microvision’s MEMS scanning mirror is a key component of the company’s modular PicoP display engine. The tiny MEMS scanning mirror itself is less than one square millimeter in area--or about the size of the head of a pin. The single scanning mirror is designed to scan in both horizontal and vertical directions so that a single beam of light can be precisely steered, in a raster-like fashion, at very high speeds to project a complete video image.
The inherent advantages of this architecture include small form factor and low power consumption, while delivering high image quality. PicoP uses a collimated beam of light to achieve very efficient full-color, hi-resolution, high-contrast images. Additionally, PicoP does not require any projection lenses and the resulting “focus-free” operation at any distance, adds another significant advantage to the PicoP based consumer projectors.
