And What Exactly Is A DLP Projector?

You hear all the tech-jargon while reviewing projector specifications but you are just an everyday user and you don’t understand jack about DLP, LCD, LCOS or whatsoever it is you may have read. I understand, it could be difficult to comprehend. So I will make it easy for my readers (you) today as I will be covering the ‘understandable tech’ behind DLP projectors.


What is DLP Technology?

Simple answer. DLP (Digital Light Processing) technology is one that employs the use of digital chips for image production.

Hailing from Texas, USA, engineers worked on an optical semiconductor chip and decided to give it a name, DLP chip. As opposed to LCOS technology in projectors, DLP has four distinct ways that make them unique and also one of the best kinds of projectors around so you are very safe buying one.


Features: What Makes It DLP

This is where I try break down the technical specs for you to understand what DLP really is here.

  1. Semiconductor: Every DLP projector has the DLP chip rooted in the heart of it. As explained above, the chip allows for image production through the semiconductor; which is seen as the world’s most advanced light switching tech (at least for now). The semiconductor consists of up to 2 million microscopic mirrors that projects any digital image to a surface. These mirrors are what create the crisp images in DLP projectors.
  2. Micromirrors: While producing an image to the screen, the micromirrors present in the DLP chip have a way of tilting to and fro the projector light source. This makes them to create a light or dark pixel on the screen they are projecting to. Whenever the micromirrors tilt away from the light, it means they are off but when they tilt towards light, it means the lights are on and they can function. A complex bit-streamed code is sent into the semiconductor as a pointer to instruct each mirror to either switch on or off – this happens very fast as it flips several thousand times within a second.
  3. Adding Color: A DLP projector is capable of producing nothing less than 16 million different color shades. The filters present in them though, create the RGB colors (Red, Green & Blue). The brilliant color technology now further explodes these colors to cyan, magenta, yellow, etc. Now all these are done within a chip. Imagine purchasing a projector with the 3-chip system; you are guaranteed to get no less than 35 trillion colors. The output from the micromirrors end up being very spectacular that is hardly rivaled by other kinds of projectors.

With these being said, if you are out looking for the best 1080p projector under $500, then you might as well lookout for one that is equipped with DLP technology. It is a great choice and you definitely will be happy with the decision.
