AppleInsider | Microvision's tiny video projector wows Macworld attendees
one of the most impressive new technology introductions at Macworld Expo was hidden away in Moscone Center's North Hall: a tiny video projector the size of an iPhone.
The highly mobile new projector was developed by Microvision, based on a new video projection technology called PicoP. Unlike existing display technologies such as Texas Instrument's DLP, which uses micro-mirrors, a high powered lamp, and a relatively large color wheel, Microvision's new PicoP uses three primary color lasers and a single aiming mirror.
The result is a highly compact projection engine that the company hopes to eventually embed into a mobile phone. The functional prototype device the company was showing paired the tiny engine (lower right black unit in photo) inside an iPhone-sized package (left unit) housing a rechargeable battery and its supporting video circuitry.
