Even today, Texas Instruments remains the primary producer of this technology. Several manufacturers licensed the technology from Texas Instruments, and to build their products around the TI chipset. Besides the use of televisions and projectors, DLP technology, used in some specialized applications such as lithography and imaging.

DLP technology differs from other video-technology, in that it is a small digital micro mirror (DMD) used to pay more1.3 million of these tiny mirrors, each smaller than the width of a human hair, either towards or away from the light source is contained in the device DLP. This process creates the light and dark pixels, which on canvas.

The light is then filtered through a color wheel rotating at 120 times per second to produce a technology that is capable of producing some of the 1024 different shades of gray. And 'this is the modulation of color that really makes a DLPfrom each other, and these gradations of color is achieved by using color filters, which shines with the right intensity of pure white light.

There are four main elements of the DLP system:

* The DMD chip that controls the mirrors

* The color wheel

* The illuminant and

* Optics

As for the photograph to produce light from the lamp passes through the filter color wheel and DMD chip, which then are mirrors on or offDepending on the color reflected from them.

This digital light processing, or DLP, technology is rapidly becoming a major player in the world of rear projection TV, and more than two million of these TVs are sold. More than 50 producers to sell at least a model of TV DLP-based, and since 2004 DLP television has a market share of 10% achieved. Furthermore, the unit of small free-standing, well known in the industry as a front headlights that were popular items, in bothWorld of business presentations and in the world of home theater.

Advantages of DLP

There are a number of significant benefits to the TVs that use DLP technology to enable them to produce. Some of these benefits include:

* Images are smooth and free movement of

* No possibility of screen burn

* A good contrast

* Good color depth

In addition, DLP rear projection televisions are generally smaller, thinner and lighter inweight than traditional CRT TVs of comparable size. Another potential advantage of the new DLP technology is that the light source is replaceable, which may be capable of a longer life compared to traditional CRT, or the new plasma screen. The DLP light source unit is much easier than replacing a model liquid crystal, and several models of DLP television, lighting feature, which is easily changed by the user. Obviously no one wants to replace the light sourcebefore his time, and the latest LED lighting market, launched in April 2006, has been shown to last 20,000 hours before being replaced.

Disadvantages of DLP

Of course there are some disadvantages of DLP TV well, and it is important for them in the market for a new TV to be aware of these potential pitfalls. For example, in some single-chip DLP design, the audience that the effect of "rainbow, created byaffect how colors appear on the TV and seen by the viewer.

Beyond the rainbow include some potential drawbacks of DLP technology:

* It is thinner or as thin as LCD or plasma, comparable even if the weight

* Some models have a noisy fan

* The replacement bulbs can be very expensive, from $ 200 to $ 500

Competing technologies

The main competitor in the market for DLP rear projectionTV is known as LCOS (liquid crystal on silicon). This technology creates an image with a stationary mirror which is mounted on the surface of a chip and then use a matrix liquid crystal to control how much light is reflected to create the image. These competing standards is still working, so it is important to act carefully and read a lot of reviews before making an outright purchase.

When you buy a DLP TV, it is important that the course to learn howas you can about new technologies, and it is equally important to look around for the best possible price. When you buy a new DLP television, is important to look closely at the nature of the receiver's user device. Many modern television sets are designed for multi-unit system, which means that not only are capable of reading the NTSC signal used in North America and Japan, but will also be able to cope with competition rules as non-PAL and SECAM . Can be an importantconsideration, so it's important to ensure that you understand the various formats and how they affect you as a consumer.

It 'important to consider the nature of the components that use the new DLP tv connected. Most modern televisions are built to receive signals, not only cable boxes, satellite TV, but DVD players, video recorders and even computers. The presence of a VGA or DVI connection allows the device to function as a computer monitor and a TV, butIt 'important to be cautious when using any form of rear projection TV for this purpose. While the plasma television can monitor computer, often excellent, making DLP technology, such as the power struggle for depth and resolution of computer users who are used to provide.

Even if the prices on televisions in general, and DLP TVs, in particular, has become a much more convenient to do in recent years, these TVs are still the most important purchases, and is useful to show to buy itdeserve. As with any purchase, shop around carefully will help you get only the lowest price, but the best overall value is not so good.
