Digital Light Processing (DLP)
DLP is a method of displaying images developed by Texas Instruments.
DLP projects video images by reflecting a light source off an array of tens of thousands of microscopic mirrors.
Each mirror represents one 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 colors. Single-chip arrays use a color-filter wheel that alternates each filter color in front of the mirror array at appropriate intervals.
