4.4 Adding Color

The on and off states of each micro mirror on the DMD chip are coordinated with the three basic building
blocks of color
–
Red, Green & Blue (RGB). For example, a mirror responsible for projecting a purple pixel will
only reflect red and blue light to the projection surface. The switching of the mirrors and the proportion of time
they are 'on' or 'off' is coordinated according to the color shining on them. To an observer, these rapidly
alternating flashes are not seen in the image; instead they see the projected image as a full and correct color
image.
4.5 Single chip DLP projection system

Image 4-7
Televisions, home theatre systems and business projectors using DLP
™
technology rely on a single DMD
chip configuration like the one described above. White light passes through a color wheel filter, causing red,
green and blue light to be shone in sequence on the surface of the DMD. The switching of the mirrors and the
proportion of time they are 'on' or 'off' is coordinated according to the color shining on them. The human visual
system integrates the sequential color and sees a full-color image.
