DLP is being used in televisions today to make crystal clear images appear on the screen. The term DLP itself means Digital Light Processing.  Basically there is a small microchip with tiny mirrors on it, which accepts light from a bulb that shines through a color wheel and the the mirrors twist and turn to reflect the appropriate angle of light to the screen and provide a crisp clear high-def image on the screen. This technology is used in projectors like the ones used for business presentations or in colleges, and in DLP tvs like the large wide screens seen at Amazon or Best Buy.

Here is an image of how the color of light is determined and reflected off of the mirrors.

DLP flowchart  DLP technology is allowing for very large size screens to be built which can range from 42 inches, up to 61 inches and this will only grow as technology advances and they figure out how to get the image to retain its quality as the sizes grow larger.

One downside to owning a DLP television is that the bulb has to be replaced after a few thousand hours and can cost a few hundred dollars, depending on the model of the TV and the type of bulb used.

That’s all for DLP, the next time you are planning on upgrading your tv to a HDTV, consider buying a DLP TV, as their prices are slightly lower than a plasma TV and the picture quality is fairly comparable.
