blue laser light

Your next cellphone could have a 100-inch screen—without getting an inch bigger. Microvision's tiny PicoP projector can turn a wall, tabletop or any other surface into a display. It's small enough to fit in pocket-sized gadgets because it uses lasers, which sip power, are extremely bright, and produce little heat. They also do away with bulky lenses: The pinpoint beams are always in focus, from any distance.

Think the iPhones 3.5-inch screen is big? How about a handheld with a 100-inch screen? Thats the promise of Microvisions PicoP laser projector.

By bouncing pulse of red, green, and blue laser light of a vibrating mirror, the PicoP can paint WVGA (848x480-pixel) images up to 100-inches diagonal in a dark room—or about 12 inches under bright lights—on a wall, tabletop or any other surface.

Measuring a scant 0.26 by 0.79 by 1.57 inches, the PicoP is about the size of the original cellphone cameras, and Microvision hopes to make it just as ubiquitous in cell phones and other handhelds.

For starters, though, Microvision will bundle the PicoP with a battery in a separate handheld device, about the size of an iPod—called the SHOW, a prototype that the company debuted today. Microvision says its already inked deals with companies that will sell the SHOW under their own brands before years end. Prices arent set, but spokesman Matt Nichols says they could be made and sold profitably for under $500.

Microvision appears to be leading the slow-paced race with Light Blue Optics and Texas Instruments to bring the first micro projectors to market. Like Microvision, TI did show an early prototype laser projector at last years Consumer Electronics Show. But TI has since decided to switch from lasers to light-emitting diodes for its Pico Projector, and it is not expected to show anything new at the 2008 CES next week.—Sean Captain

Sony's high-capacity blue laser DVD recorder, set to debut in the United States this fall, crams five times more information on a
disc than the standard red laser version does and heralds the arrival of next-generation technology. Enthusiasts eager to get their hands on that much data capacity, however, may think twice after learning that production snags boosted the DVD's price to about $3,500. But researchers at BlackLight Power in Cranbury, New
Jersey, say they have made a discovery that may help overcome technical hurdles and get reliable blue lasers to market.
