What is DLP?

DLP = Digital Light Processing technology
At the heart of every DLP® projection system is an optical semiconductor known as the DLP® chip, which was invented by Dr. Larry Hornbeck of Texas Instruments in 1987.

The DLP® chip is probably the world’s most sophisticated light switch. It contains a rectangular array of up to 2 million hinge-mounted microscopic mirrors; each of these micromirrors measures less than one-fifth the width of a human hair.

DLP technology is a revolutionary display solution that uses an optical semiconductor to manipulate light digitally. The result is maximum fidelity, with a picture whose clarity, brilliance and color must be seen to be believed.
White light passes through a color wheel filter, causing red, green and blue light to be shone in sequence on the surface of the DMD. The switching of the mirrors, and the proportion of time they are ‘on’ or ‘off’ is coordinated according to the color
shining on them. The human visual system integrates the sequential color and sees a full-color image.
