How does it work?
A digital projector’s technology transfers the digitized image file onto three optical semiconductors known as Digital Micro mirror Devices, or DMDs. Each of these chips is dedicated to one primary color-red, green, or blue. A DMD chip contains a rectangular array of over one million microscopic mirrors.
Light from the projector's lamp is reflected off the mirrors and is combined in different proportions of red, green and blue, as controlled by the image file, to create an array of different colored pixels that make up the projected image. Think of the DMD mirrors as the colored cards held up by an audience in a sports arena to create a giant image. Each person holds up a single colored card, yet when combined, these thousands of cards create a picture. If the card colors are changed, the picture changes too.
The DMD mirrors tilt either toward or away from the light source thousands of times per second to reflect the movie onto the screen. These images are sequentially projected onto the screen, recreating the movie in front of you with perfect clarity and a range of more than 35 trillion colors.
