While
“palm-top” projectors have recently made a splash in the
projection marketplace, consumer demand points to brighter, smaller and
more affordable projection devices. Target applications for pocket
projectors range from compact units for business presentations to
personal entertainment displays. A new class of even smaller
“embedded” projectors will be integrated into mobile phones
and other similarly sized devices, allowing users to watch streaming
video, digital TV or surf the web.
NECSEL breaks new ground in
miniature projection by providing high-power, efficient output from a
compact, affordable package. In fact, current palm-top projectors based
on LED lighting measure over 30 cubic inches, produce around 20 lumens,
and cost in excess of $700.00. NECSEL prototypes display a light output
of over 200 lumens with both device size and cost cut in half.
NECSEL can also be coupled with 2D MEMS scanning technology [Editor’s note: That’s Microvision, folks]
to enable “embedded” projectors. Since NECSEL is inherently
small, bright and its light output can be directly modulated for gray
scaling, it is the only light source to date that makes possible these
revolutionary devices. The result is a new category of ultra-compact
projector that produces brilliant, colorful, high-contrast images that
are always in focus, even on curved surfaces.
