DLP projector technology uses a Digital Micromirror Device, or DMD, to modulate light and create the projected image. This guide explains how DMD micromirrors work, the difference between single-chip and three-chip DLP systems, how color can be generated and processed, how laser light sources work with DLP imaging, and why optical design, resolution, thermal management and signal processing all influence final image performance.

A projector optical engine is the internal imaging system that converts light from the projector's light source into a controlled image before it passes through the projection lens. This guide explains the main components of 3LCD and DLP optical engines, how laser light is processed through the optical path, and why imaging architecture, lens design, thermal management and calibration all influence projector brightness, color and image quality.
