It's almost too good to be true. A laser projector that displays a 2048x1280 screen, infinite focus, no moving parts, and runs on 1.5W of power. This is the next display revolution IMO - let's do away with those bulky LCDs! (LOL)


Looks like other people are doing it as well, but in colour (http://popsci.typepad.com/popsci/2008/01/microvision-pre.html).

Cool. Can't wait to have a pocket bluetooth projector that runs on standard cell phone batteries.

and runs on 1.5W of power.

Thats the impossible part. I did one of those lame $20 projection tv hacks and
the inabilty to focus was a problem but the real application killer was even in a pitch black room it was not bright enough.

2048 x 1280 x [680 nm x 680 nm x 3] = about 4 mm^2
so a 2mm x 2mm LCD projector panel might be possible if my math is right.
