How DLP Works Video

Overview:

DLP (Digital Light Processing) is a display solution that uses an optical semiconductor to manipulate light digitally. DLP is highly reliable, all-digital display chip that delivers the best picture across a broad range of products, including large screen digital TV’s. With more than 7 million DLP systems shipped to more than 75 manufactures since 1996.

DLP technology is used in rear projection TV’s and projectors. DLP technology can create 16.7 million to 35 trillion colors and 10,000:1 contrast (Same as high end plasma). With DLP you get a bright picture and same quality as Plasma TV’s. As a result DLP can be viewed in bright rooms. DLP rear-projection TVs offer several advantages over CRT rear-projection systems, for a modestly higher price — along with video performance that's superior in some ways to more expensive flat-panel displays.

Things to keep in mind when buying:

• Make sure DLP is HD, not ED
• Choose models that are 720p or 1080p lines of resolution
• Make sure has one or more DVI or HDMI (more is better)
• Contrast Ratio 3000:1 or geater
• Brightness 600 cd/m² or greater
• Ask to watch the DLP on a HDTV channel and standard channel, to make sure you like the picture quality of that model.
• Ask for the remote and mess with the Picture and color settings.
• Once you find the model you like, check online for information and problems with model. Also see if another manufacturer offers a better product for around the same price.

Advantages:

Even though more expensive than CRT projection systems, it is less costly than LCD or plasma. DLP rear-projection sets deliver excellent picture quality in a chassis that's significantly sleeker than that of a traditional projection TV. The DLP light engine is capable of very high brightness (though not as bright as LCD), so a DLP set can be viewed even in bright room conditions. The distance between the pixels on a DLP display is quite small, minimizing the "screen-door effect" (seen more prominently in LCD displays) to create a full, seamless image. Because of DLP's fine reproduction of blacks, its contrast performance is superior to any other non-CRT projection technology. The single-light-source design eliminates the convergence issues that plague CRT and some other projection systems, and limits maintenance costs (a single bulb to replace, for example).

Disadvantages:

DLP is not as bright as LCD technology, nor as compact as LCD or plasma flat-panel models (though the typical DLP rear-projection set is much shallower than most CRT-based rear-projection systems). Additionally, certain especially sensitive viewers notice an artifact commonly referred to as the "rainbow effect," a consequence of DLP's temporal approach to color formulation. Those viewers may momentarily see the light split into its component color spectra as their eyes travel quickly from one part of the screen to another — particularly when seated close to the screen. The unlucky few will likely find this quite distracting; fortunately, most viewers won't even perceive a problem. The latest-model DLP sets incorporate improved color-wheel technology in an effort to further minimize this artifact.
