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 uses a color wheel to split white light from the lamp into its constituent red, green and blue. The color wheel sends red, green
and blue light sequentially to the DMD™. The modulated output of the DMD™ is synchronized with the color wheel to form the projected full
color image.
