If you’ve been thinking about buying a home theater projector, maybe to associate to an Hdtv tuner, and have read reviews or done a miniature bit of research, you’ll be aware that there are two technologies competing for the contents of your wallet.

Both Lcd and Dlp are used in projectors convenient for home theaters, but they work in quite different ways and yield slightly different results. If you ask colse to ‘ particularly in electronics stores, you’re likely to be provided with a mass of data that’s confusing and often just plain wrong. So here, in an endeavor to clear the fog surrounding projectors, is our guide to Lcd v Dlp.

LCD Technlogy

Lcd

Lcd projectors have three detach Lcd panels, one for red, one for green, and one for blue components of the image being processed by the projector. As light passess straight through the Lcd panels, personel pixels (or photograph elements) can be either opened or accomplished to either allow light to pass straight through or be filtered out. In this way the light is modulated and an image projected on to the screen.

Lcd projectors have historically had three main advantages over Dlp. They yield more spoton colors (due to the three detach Lcd panels), they yield a slightly sharper image (although this is as good as undetectable when watching movies) and they are more light-efficient, which means they yield brighter images using less power.

However, Lcd projectors also have some disadvantages, although as the technology improves these are becoming less and less relevant. The first of these is pixelation, or what’s known as the screen door effect. This means that sometimes you can see the personel pixels and it looks as though you are viewing the image straight through a ‘screendoor.’ The second historic disadvantage of Lcd v Dlp is that Lcd doesn’t yield absolute black, which means that contrast is less than you would get with Dlp.

However, the advent of higher resoltion Lcd projectors (particularly ‘Hd-ready’ projectors which have a horizontal resolution of 768 pixels or greater) means that pixelation is less of a qoute than it used to be. And the improved potential of Lcds to yield high-contrast images is also allowing them to be taken more seriously by home theater enthusiasts.

Dlp

Digital Light Processing (Dlp) is a technology advanced by Texas Instruments and it works by projecting light from the projector’s lamp onto a Dlp chip, made up of thousands of tiny mirrors. Each mirror represents a singular pixel and directs the light projected onto it either into the lens path to turn the pixel on or away from it to turn it off. Most Dlp projectors have only one chip, so in order to reproduce color, a color wheel consisting of red, green, blue and sometimes, white filters is used. The wheel spins between the lamp and the chip and changes the color of the light hitting the chip from red, to green, blue. Each mirror on the Dlp chip tilts towards or away from the lens path depending on how much of a singular colour light is required for that pixel at any given instant.

The key advantages Dlp has in the Lcd v Dlp debate is that Dlp projectors tend to be smaller and lighter, have good contrast, and don’t suffer the same pixelation problems as Lcd projectors. There is one qoute that some users description with Dlp projectors, although it appears to only affect a very small whole of people. Because of the way Dlp works, at any given instant, the image on screen is either red, green, or blue. However, the images turn so quickly, that the human eye doesn’t detect this and your brain puts the red, green and blue images together to make a perfect frame of video. Unfortunately, some population can see the personel colours, and others can detect them enough to cause eye-strain and headaches. However, technology has improved significantly with the introduction of six-color wheels and faster rotation speeds. The rainbow result should be a qoute for even fewer people. The best way to find out if you’re affected is to try out a Dlp projector, maybe by hiring one, before you buy.

Technology in both Lcd and Dlp projectors is enhancing all the time. However, at the time of writing Dlp still has a miniature edge in the home theater market.
