Looking for a way to differentiate among the ever-expanding niche of pocket projectors
, researchers at the Fraunhofer Institute for Applied Optics and Precision Engineering (IOF) of Germany are working on an OLED
panel-based mini projector, using static optical systems and not the usual reflective system à la DLP. Currently being shown at SID Display Week 2009, the decidedly green picture (seems to be the norm with OLED prototypes
these days) forms via a 6-inch VGA screen from 30 to 50 centimeters away, and the machine itself takes up just about ten cubic centimeters of space. Despite all the faith, there's still the rather nasty problem of luminance, which the scientists estimate needs to be about four or five times as bright as current levels -- but hey, you gotta start somewhere, right?
