DLP Technology
If you are in the part in your life when you think its about time to buy a home theater projector which will connect you to a HDTV tuner, then you probably learned a lot from different reviews on making the right decision. If you did a little research you will probably have heard that there are two different technologies out there that will be competing for your service.
They are LCD and DLP projectors. Both of them are suitable to be used for home theaters, but the function and the results they produce definitely differ from each other. And if you are not an expert or if you don't go and ask around, you might be in the danger of purchasing something that will not yield the results that you would like in the first place.
At the present times, Digital Light Processing or DLP technology has overcome and surpassed the drawbacks and limitations of the usual LCD technology that is used in projector lamps. The use of DLP technology came into the front when it replaced the poor and somewhat blurred quality image that is produced by LCD. Because of this recent technology, a sharper and clearer image of what you are watching for is obtained.
The projection system of DLP works based on a DLP chip. These actual chips are made up of several micro mirrors that are in turn made up of aluminum so that the purpose of reflecting light and forming clearer and brighter pictures. These micro mirrors are arranged so as they will look like a matrix and each mirror represents a pixel that is meant to refine the image quality that we see.
Another thing to note about DLP is that its projectors tend to be lighter and smaller, it has better contrast and unlike LCD, it does not suffer or have the same pixelation problems. Although there is one problem that has been reported by some users of DLP. It has something to do with the way it works, sometimes, at a given instance, the image one sees on the screen is blue, red, or green. And although these colors appear very fast and instant, some may not even notice them. But for those who do complain of eye-strain and headache.
The great color technology is another essential advantage of DLP technology. The light generates white light that gets directed toward the chip which filters the surface and sepeartes white light into a minimum of 3 other colors. About 16.7 million colors can be produced by just one single chip in the projector system of DLP.
These systems also have better contrast ratio and even efficiency in light use. This contrast ratio compares the darkest black between the brightest white that any projecotr can use. The best contrast will have a greater dark level and will show a more true to life presentation of darker scenes in movies and other programs.
But of course, like any other thing, this goodness of the DLP technology also has its share of drawback. Although it is offering better performance at a certainly lower average cost, some issues are also attached to it. And one of the most common of it is the lamp life which is actually based strictly on the usage. The estimated average life span of a DLP lamp is between 1000- 2000 hours. This is due to the quality of the lamp which can actually and dramatically varies according to the brand that you will buy. So, obviously and expectedly, lower usage would definitely lead to a longer interval of replacement.
