Inside the PicoP Display engine…

I’m off on Monday, March 30th, to the Global Press Summit with Ian Brown, VP Sales & Marketing. The Global Press Summit, held in San Francisco, is a media only event where 50+ editors from the world’s leading embedded systems and electronics publications converge to learn about what’s new. Microvision was invited to participate on a panel to discuss the Growth in Micro-Electro-Mechanical Systems (MEMS) and to showcase our single scanning mirror MEMS-based Pico Projector. If we get some additional press coverage from this event, I’ll make sure to post the articles.
And for those that might be asking…what is MEMS, and why is it important to Microvision’s solution? Micro-Electro-Mechanical Systems (MEMS) is the integration of mechanical elements, sensors, actuators, and electronics on a common silicon substrate through microfabrication technology. Often referred to as a system-on-a-chip, MEMS are enabling the development of smart products, ranging from solutions in automobiles, medical devices, mobile phones, pico projectors and more. While parts of the technology industry are experiencing reduced demand during the global economic slump, the MEMS industry continues to grow at a double-digit clip, according to industry analysts.
Because Microvision’s MEMS single scanning mirror device, which is an integral component of our PicoP display engine, is manufactured using batch fabrication techniques similar to those used for integrated circuits, unprecedented levels of functionality, reliability, and sophistication can be placed on a small silicon chip at a low cost. The figure included in this post shows the basic layout of the PicoP display engine, which is an elegant architecture. Seen in the diagram are:
–Red, green and blue lasers, each with a lens near the laser output that collects the light from the laser and provide a very low NA (numerical aperature) beam at the output.
–The light from the three lasers is then combined into a single white beam.
–The beam is relayed onto Microvision’s biaxial MEMS scanning mirror that scans the beam in a raster pattern.
The assembled PicoP display engine is just 7mm in height and about 5 cc in total volume, which is small and thin enough to be embedded inside sleek, contemporary mobile devices.
You can learn more about MEMS by visiting the MEMS Industry Group Web Site. Microvision has been a member of the MEMS Industry Group for the past two years.
Look forward to reporting back to you from San Francisco, have a great weekend!
