Digital Micromirror Deice c!i":

At the heart of every DLP™ projection system is an

optical semiconductor known as the Digital MicromirrorDevice !t contains a rectangular array of up to " million

hinge#mounted microscopic mirrors$ each of these

micromirrors measures less than one#fifth the width of a

human hair


16/20

THE #R$YSC$LE IM$#E:

A DLP™ chip%s micromirrors are mounted on tiny hinges

that ena&le them to tilt either toward the light source in a

DLP™ projection system '()* or away from it '(++*#

creating a light or dark pi,el on the projection surface


17/20

$DDIN# COLOR:

-he white light generated &y the lamp in a DLP™

projection system passes through a color wheel as it travels to

the surface of the DLP™ chip -he color wheel filters the light

into red. green. and &lue
