CES: 3M projector for phones, cameras
Video projector technology heads for the phone






For several years people have been talking about the idea of miniaturising a projector so that it's small enough to fit inside a mobile phone or digital camera. Now it's finally been done, and 3M is demonstrating a prototype of such a device at this year's International Consumer Electronics Show.
The mobile projector is about a centimeter thick and about 4 centimetres tall by 3 centimetres wide - small enough to fit inside portable devices like phones, PDAs or a digital still camera, said Todd Rutherford, product development specialist with 3M's optical systems division.
It uses an LED as the light source and can project a VGA resolution (640 pixels by 480 pixels) image through a lens that's about a centimeter in diameter.
3M is demonstrating the projector at CES built into a small handheld device that runs video from flash memory. The image projected onto walls or other light surfaces was good enough and easy enough to see over a distance of about half a metre, although it suffered over greater distances due to the bright lights of the show floor.

3M Beats Everyone to the Micro Projector Business
People who have thought much about it have concluded that projectors are the one way to reconcile ever-tinier gadgets with the ever-more data and media we have on them. And plenty of companies have been trying to build a micro projector that you can carry in your pocket or even get built into your cellphone or iPod.
More details and incredible video after the jump.

3M’s projector shows full-color, standard def video at a rate of at least 60 frames per second—television quality. Its 10 lumens of brightness make it powerful enough to overcome bright room lighting to project an image about 15 inches across. When we took it into a dark room, it could easily do 50 inches.
Instead of lasers, which Microvision and its rival Light Blue Optics are using, 3M uses LED for illumination. They wouldn’t tell if it’s one white LED or three (red, green, and blue) bulbs. But given the size of the projector and the color quality—which was nice, but not stunning.
Texas Instruments is trying to do the same thing with LED and it’s DLP imaging chip—similar to what you get in rear-projection TVs from Samsung. But 3M is using liquid crystal on silicon—basically and LCD on a mirror that bounces light out the front of the projector.
3M won’t be selling final products, but will supply the guts of the projector to companies that will sell it either as a handheld accessory (about the size of an iPod Classic) or possibly even built into gadgets. No word yet on who those companies are?
The projector’s a bit fat for cellphones—at least those made in the last five years. But 3M promises to get it way smaller (and brighter and with higher screen resolution) in the coming years.
What can you use it for? Well, the demonstration products I saw take flash memory cards, have USB ports and/or have regular video inputs. I can see it making a really nice iPod accessory.

AAXA is the outfit responsible for serving up to the pint sized P1, this is demonstrating an exactly what a hasty refresh cycle looks like by dishing out the higher P2 just a few months later…….
