Digital Light Processing (DLP®) technology works by reflecting light off microscopic mirrored panels called Digital Micro-Mirror Devices (DMD). Each DMD consists of millions of tiny mirrors, each acting as a single reflective pixel in the resolution of the projected image.
A native HD resolution image is made up of 1080 horizontal lines each containing 1920 pixels. By the same measure, a DLP projector with HD resolution would use either 1 or 3 DMD chips (higher-quality projectors use three chips, one each for the Red, Green and Blue color signals) made up of 1080 rows of mirrors, with each row containing 1920 microscopic mirrors.
The advantage of this all-digital system is that it consistently offers better light efficiency and color control in comparison to any other projection technology. This is because each individual pixel is controlled for a smoother, cleaner image since the space between the mirrors on a DMD is so small. Because all the light is reflected out of the projector, DLP projectors also offer higher brightness from smaller units and consequently use less power.
