3rd stage colour creation : 

3rd stage colour creation

1) Color is added as white light from the lamp passes through a color wheel filter2) Color Wheel – RED, GREEN & BLUE3) As wheel spin, mirrors on DMD are tilted on for the exact amount of time required for each basic color4) Only 1 color is shined onto DMD at a time :

5) When spinning fast enough, human eyes blend alternating flashes to view “more” colors in the projected image :

The memory in a graphic display device which holds a complete one-bit-per-pixel image. Several bit planes may be used in conjunction to give more bits per pixel or to overlay several images or mask one with another. :
