How Do Projectors Work?

Ever wondered how a projector turns a tiny beam of light into those massive, vivid images at the movie theater? The answer involves clever optics, liquid crystals, and millions of microscopic mirrors working together at incredible speed. In this video, we explain how projectors work by breaking down the two most common types -- LCD and DLP. You'll learn how white light is split into colors using dichroic mirrors, how liquid crystal displays control each pixel, and how Digital Micromirror Devices create high-definition images.
