Digital Projection HIGHlite 5000GV, User Manual

Page: 80 / 94

A DMD™ (Digital Micromirror Device™) is a true digital light modulator and
utilises 786,432 moving aluminium mirrors, with each one representing a pixel in
the final projected image. Each mirror is suspended over address electrodes by a
torsion hinge between two posts. Depending on the voltage polarity applied, each
mirror will either tilt to left or to the right. When light is applied to the complete
DMD™, only the light redirected from a mirror tilting to the left is projected.
The projector optically filters white light from the lamp into its constituent red,
green and blue. Each colour illuminates a separate DMD™ whose modulated output
is then recombined with the other two to form the projected full colour image.
