How Digital Light Processing (DLP) works

Digital Light Processing projectors use a chip that is covered with tiny mirrors that tilt back and forth. When the mirror is tilted one way, it reflects light out through the front of the projector, creating a bright pixel. When the mirror is tilted the other way, the pixel is dark. In this video, I explain how DLP works and show a macro-scale model.
