Digital Micromirror Devices™
A Digital Micromirror Device™ (DMD™) is a digital light modulator fabricated
from moving aluminum mirrors. Each mirror, which acts as a pixel, is suspended
between two posts by a thin torsion hinge and can be tilted to the left to produce
a bright pixel or to the right for a dark pixel. There are three DMDs™ in the projec-
tor, one for each of the primary colours, each containing 786,432 mirrors arranged
in a 1024 x 768 array (gv models) or 1,310,720 mirrors arranged in a 1280 x 1024
array (sx models).
Cooling System
During normal operation considerable heat is generated inside the projector,
therefore, an air cooling system is provided. This consists of a powerful fan which
draws cool air through specially designed air ducts within the case to distribute it
over the lamp and other components. The cooling system provides maximum
cooling whilst minimising noise output.
Do not move or tamper with any seals or ducting panels on the projector or the
air flow could be disrupted and cause the projector to overheat. Always keep the
air inlets and outlets clear of any obstruction.
