An Introduction to DLP & LCD Projectors

Deciding on the right projector is not as easy as it used to be. Especially with all the features and specifications to compare, also not to mention the great number of digital projectors and technologies on the market today. You can see an example of this just by researching the latest Optoma DLP Projector. We will learn about two important yet easy parameters in this post; they are projector panel type (LCD or DLP) and brightness. Knowledge is always a good thing, and we hope that learning about these two parameters will allow you to make the most informed buying decision about your next digital projector.

Projector Brightness

One of the first things you might want to compare when choosing a projector is it’s brightness. Your screening environment will often dictate what you choose and how many lumens (the measure of brightness) you need. In addition to light and lumens, adjustability plays an important role for portable projectors. The higher the brightness threshold is, the pricier it’s certainly going to be. Here’s a breakdown of the ANSI luminosity levels and their standard usage, but keep in mind it’s all up to you to choose which would be best.

• 3000 or more ANSI lumens. Good for projecting in bright areas, convention stages, outdoor concerts or large theater venues.

• 1800 – 3000 ANSI lumens. Perfect for classroom presentations and big lectures, high end home theater and TV viewing, DVDs and more.

• 1000 to 1800 ANSI lumens, good for basic entertainment purposes, portable business presentations, static graphics and inexpensive game use.

Technology Type (LCD or DLP)

There’re two kinds of projectors; basically, the LCD and DLP panels. LCD is the most popular of the two currently. LCD Infocus Projector panel technology may cost slightly less than DLP panels. LCD technology also seems to provide more vibrant color saturation and greater levels of brightness. Looking at the actual specs with the strengths and weaknesses of the LCD panel when choosing a projector can prove very useful.

Projectors utilizing DLP technology can cost the same or slightly more than LCD projectors but are generally thought to produce deeper, darker black levels and higher contrast ratios than LCDs. Home theater buffs also seem to gravitate to DLP projectors for their greater contrast and general ability to project warm, film like images. Some feel that DLP lamps are stronger and generally last longer than LCD ones. Be sure to view some of the actual specifications of a typical DLP unit like the DLP Infocus Projectors to see how the specs you just learned about add up in actual projector models.
