3M's miniature projection engine
January 22, 2008 Miniature projection modules are seen as the answer to the problem of combining "big-screen" convenience with ever shrinking mobile device platforms and, in the same way that mobile phone cameras seemed to become commonplace almost overnight, consumers can expect highly-effective projection to become standard in phones and other handheld equipment in the not-too-distant future. The latest development from 3M gives a clear indication of where the emerging field is headed. Designed for integration into virtually any mobile platform and now available to manufacturers, the company's LED-illuminated projection engine is capable of throwing a 40-inch or larger VGA image from an ultra-compact module that's less than half an inch thick.
