Leibson's Law: It takes 10 years for any disruptive technology to become pervasive in the design community. This blog is about the disruptive technologies that either have or will win over electronic engineers, some that won't, and why. Written by Steve Leibson, Tensilica's Technology Evangelist.

Laser, Laser on the Wall: MicroVision's Microprojector

I’m at the Globalpress conference in San Francisco and am listening to a presentation by Alexander Tokman, CEO of MicroVision. 
He’s discussing and demonstrating an amazing module that projects video on any available surface. The company’s PicoP display engine employs three semiconductor lasers (red, green, blue) and a MEMS 2-axis scanning mirror to project better-than-standard-definition video (854x480 pixels). Because it uses lasers as light sources, the projected image is pretty bright although a darkened room is definitely required, as with nearly any projection technology. Also, there are no lenses in the device so the image is instantly in focus no matter the distance to the projection screen. The module itself is already small enough to fit into a cell phone, and will shrink further in the future. It consumes 1.5W. Target cost for the display module is $100. Target products include cell phones, laptops, and PDAs. Very cool technology.

Very exciting. Driver..? a PC..? Thanks for news.

That would be awesome if you could hook it up to a USB port or firewire and project a second monitor on the wall, or small silver screen.

Currently, the MicroVision PicoP display engine accepts "video," which I take to mean a sequence of scan lines organized into frames (either interlaced or progressive). Some sort of frame buffer and control electronics must be added to create a projector. Such a projector might accept video as well as streamed frame sequences over USB 2.0 or FireWire. If I were designing a projector, I'd probably create a PDA-sized device as a laptop peripheral. The 1.5W power draw of the projector means that you'll need a battery pack with pretty good capacity.
