How Do Digital Projectors Produce 281 Trillion Shades of Color?
At the heart of the projector, a precision prism splits white light into primary colors. The lights inside this machine are brighter than the headlights on a jumbo jet! MACHINES: HOW THEY...

Narrator: DIGITAL PROJECTORS. THEY CREATE DAZZLING IMAGES WITH INCREDIBLE RESOLUTION. BUT HOW CAN DIGITAL TECHNOLOGY PRODUCE ULTRA-HIGH-DEFINITION MOVING IMAGES THAT EVEN FILM CAN'T BEAT? AT THE HEART OF THE PROJECTOR, A HIGH-PRECISION PRISM SPLITS WHITE LIGHT INTO PRIMARY COLORS... AND THEN BEAMS IT ONTO THREE MICROCHIPS. ON THEIR SURFACES, 8.8 MILLION MIRRORS SMALLER THAN A PINPRICK. THEY FLICKER ON MICROSCOPIC HINGES TO SPLIT UP THE LIGHT BEAM INTO 8.8 MILLION PIXELS THAT FORM A MOVING IMAGE. THE PRISM MERGES THE LIGHT FROM THE 3 CHIPS TO PRODUCE 281 TRILLION SHADES OF COLOR. THE PROJECTOR CONSUMES 1,600 WATTS OF POWER AND GENERATES INTENSE AREAS OF HEAT THAT COULD RUIN THE PROJECTOR'S IMAGE. SO, 105 METAL SPIKES DRAW HEAT FROM EACH OF T...
