There are number of types of HDTV (High Definition Television) on the market today. No doubt, you have heard names such as Plasma, LCD (Liquid Crystal Display) and Rear Projection. There is another type of HDTV, which is making inroads into the world of HDTV. It is called DLP, which stands for Digital Light Processing. If you are the type of person who can frequently be seduced by technology and can’t wait to adopt technology as soon as it comes to market, then you probably already own a DLP TV! If you are a lover of high-tech devices and are in the market for a High-Def TV, then a serious look at DLP is now mandatory. Until recently, I must confess that I had no idea that DLP was perhaps the best option in HDTV and I am still terribly impressed with how it works. DLP is based on an optical semiconductor that manipulates light digitally. It’s revolutionary and highly reliable all at the same time, and the picture is somewhere beyond stunning! It relies on two million tiny mirrors that can move thousands of times per second! These mirrors respond directly to the digital signal.

DLP works in large screen digital televisions, projectors, and even in movie theaters. They work in business, homes and professional venues of any kind. Seven million of these systems have already shipped
to 75 different manufacturers and leading electronics companies since 1996. Since there are about 15 million HDTV households in the US, at the very least, a respectable percentage of them are watching DLP right now.

DLP is in the home and it is in businesses worldwide. They are only technology that offers a projector under 2 lbs (the worlds smallest) and they can light up movie theater venues of 75 feet. This is visual excellence at its highest form. Can other display technologies make
this claim?

The crux of DLP is the Digital Micromirror Device or DMD. Picture a flat surface covered with two million mirrors. Then imagine that each of the two million mirrors can tilt or flex within the plane it exists. It does this to either reflect or not reflect light. Each of these mirrors is connected to a semi-conducting chip that is perfectly coordinated with the video signal and each mirror can move thousands of times per second because it is mounted on tiny hinges. We are talking true fidelity here. The digital signal moves the mirrors and the mirrors respond perfectly: the mirrors, controlled by a bit streamed image code, reflect a digital signal onto your TV screen or other surface! The clarity, brilliance, and color must are astoundingly magical!
These mirrors generate a grayscale image that has 1024 different shades. White light, generated by a lamp, is then passed through a color wheel and combined with the grayscale light that creates over 16 million different colors! This futuristic TV technology is here today and it is called DLP (Digital Light Processing).
