The DMD™ (continued)
Depending on the voltage polarity applied, each mirror will either tilt to the left to produce a bright pixel or to the right for a dark pixel. 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 color illuminates a separate DMD™
whose modulated output is then recombined with the other two to form the projected full color image.
