DLP Projectors – Everything You Need To Know

DLP_Projectors_informationIf you are in the market for a home, office or classroom projector, then you’ve probably heard about the two major categories of modern-day multimedia projectors which are dlp and lcd projectors. DLP stands for “Digital Light Projector” and the technology behind it was developed by Texas Instruments in 1987. DLP projectors are fairly popular in today’s market and most prefer them over lcd projectors. However, given that the technology was developed in the late late 1980’s, most people know little about how these projectors work, the pros/cons of using them and the best practices associated with their use.

This articles represents a collection of the available information that will allow you to make an informed decision.

How do DLP projectors work?

The main components of a typical home projector include the xenon arc lamp, DLP chip, projection lens and the rotating shutter. The DLP chip consists of microscopically small mirrors which are used as pixels, the number of these small mirrors corresponds to the number of pixels on the chip. Which means that 1080p projectors includes 1080 small mirrors in its DLP chip!

The rotating wheel then rotates between the chip and the lens to produce the images on the screen.

Inner Working of dlp projector


* Smaller/Lighter than lcd projectors.

*High-clarity and no pixilation problem.

*Can adjust to any screen-size.



*The Rainbow Effect: Given the inner workings of these projectors, the images at any given time on the screen are either red/blue/green or white. In most cases the images move to fast to be noticed by the human but some people can be troubled by these effects.

* Low lamp life: The brightness of the lamp will progressively be reduced and will eventually need to be replaced.

Best Practices:

Most projectors are in the $300+ range which makes them relatively expensive pieces of technology. One must exercise care in using them in order for them to last longer. Begin with reading the accompanying user manual.

Also make sure there is enough space and ventilation as over-heating can be an issue with dlp projectors (although most projectors come with an included fan).

Smoke or dust can have adverse effects on the optical lenses of the projector, hence its best to keep them away from air pollutants.

In case that the projector uses a ceiling mount, make sure that it is fitted properly and there is no chance of an accident.


Finally, we’d like to say that DLP projectors are a great piece of technology. They can provide an immersive and luxurious entertainment or work experience. They are multi-functional and can be attached with computers, DVD players, VCR players, HDTV’s and video games. However, they remain costlier than your average home appliance and due diligence must be taken during their purchase.
