In the world of high definition television sets, there appears to be only two real players. Must advertisements and even the stocking of shelves in your local electronics store would lead you to believe that only two types of HDTV sets exists and those two type are both flat panel displays with one being LCD sets and the other being plasma sets. However, this assumption could not be further from the truth. In actuality, many types of HDTV sets exist. This article will discuss just one other option, the seldomly heard of DLP set.
What is a DLP set? DLP stand for Digital Light Processing and it is a term and type of technology that is made solely by Texas Instruments. DLP is commonly used in front projectors such as movie theater setting and rear projection sets that are available in HDTV format for your home. I will focus on the latter use of DLP in rear projection HDTV set for your home.
How does the technology work? In DLP rear projectors, the image is created by small mirrors laid out on a semiconductor chip, known as a. Each mirror represents one or more pixels in the projected image. The number of total mirrors reflect the pixels rating of the set. Therefore, by adding more mirrors, a standard definition set can become a high definition set. These mirrors are moved to reflect light onto the set. Color is added by a microchip during the process.
Now as with all HDTV sets, there are advantages and disadvantages to each type and with the DLP type of set, this is no exception. First we will look at the advantages of a DLP HDTV set. DLP produces smooth, jitter free images, has great contrast, and very good color rendering. There is no possibility of burn in or image retention with a DLP set and the screen door effect that is prominent on LCD set is much less noticeable on a DLP set. A DLP's biggest advantage is that for any given screen size, it is comparatively cheaper to buy than either an LCD or a plasma set.
