In DLP projectors, the image is created by microscopically small mirrors laid out in a matrix on a semiconductor chip, known as a [[digital micromirror device]] (DMD). These mirrors are so small that DMD [[pixel pitch]] may be 5.4&nbsp;μm or less.<ref name="DLP3010">{{cite web | author=Texas Instruments | url=http://www.ti.com/product/dlp3010 | title=DLP3010 Mobile HD Video and Data Display Description & parametrics | access-date=2014-10-13 | author-link=Texas Instruments}}</ref> Each mirror represents one or more [[pixel]]s in the projected image. The number of mirrors corresponds to the resolution of the projected image (often half as many mirrors as the advertised resolution due to [[wobulation]]). [[Super Video Graphics Array|800×600]], [[XGA|1024×768]], [[720p|1280×720]], and [[1080p|1920×1080]] ([[HDTV]]) matrices are some common DMD sizes. These mirrors can be repositioned rapidly to reflect light either through the lens or onto a [[heat sink]] (called a ''light dump'' in [[Barco (manufacturer)|Barco]] terminology).

Rapidly toggling the mirror between these two orientations (essentially on and off) produces [[grayscale]]s, controlled by the ratio of on-time to off-time.
