Clarinet's tw service reports that TI has a new digital projection
display system that uses TI's Digital Micromirror Device, or DMD.  The
DMD is a micromechanical spatial-light modulator fabricated on silicon
via conventional semiconductor-fabrication techniques.

The device operates by reflecting light rays from an external source
into the pupil of an imaging lens, which then projects the digitized
image onto a screen.

At this week's demonstration, the system projected images 12 feet onto
a 60-inch diagonal screen.

TI received a four-year contract in 1989 from DARPA as part of the
agency's effort to develop the high-definition technology in the
United States.

TI is one of four contractors DARPA originally selected for the
program's projection-display technology development. In designing that
system, TI subcontracted The David Sarnoff Research Center in
Princeton, N.J. to help with the project.
