Digital Light Processor. A video projector using Texas Instruments DMD chip(s). These chips involve a process of projecting video images using a light source reflecting off of an array of tens of thousands of microscopic mirrors. Each mirror represents a pixel and reflects light toward the lens for white and away from it for black, modulating in between for various shades of gray. Three-chip versions use separate arrays for the red, green, and blue colours. Single-chip arrays use a colour-filter wheel that alternates each filter colour in front of the mirror array at appropriate intervals.
