What is DLP and how does it work?


DLP, short for Digital Light Processing, created and commercialised by Texas Instruments and is used in rear projection TVs and modern colour digital projectors including a large portion of mini projectors.

It works by creating the image with microscopically small mirrors laid out in a matrix format on a semiconductor chip called the Digital Micromirror Device (DMD).

DLP has been around since the late 1980’s, however it’s only recently with the replacement of the mechanical spinning colour wheel and light lamp combination that DLP used to rely upon with newer coloured LEDs and Lasers that has made this technology much smaller platforms and affordable for inclusion into mini projectors.

DLP offers smooth, jitter free images with excellent grayscale linearity and with no replacements of light bulbs in the new ranges of DLP projectors this technology is quite economical.
