Features and benefits of DLP TVs

Even today, Texas Instruments continues to be the leading manufacturer of this technology. Many different manufacturers license the technology from Texas Instruments and build your products around the TI chipset. Besides their use in televisions and projectors, DLP technology is used in a number of specialized applications, such as lithography and Imaging.

DLP technology differs from other video technology that uses a small digital micromirror device (DMD) skew more than 1.3 million of these small mirrors, each one smaller than the width of a human hair toward or away from the light source is contained within the DLP device. This process creates dark and light pixels that appear on the projection screen.

The light is then filtered through a spinning color wheel to 120 times per second, to produce a technology that is capable of producing some 1024 different shades of gray. Is this gradient that actually does DLP technology stand out, and these gradients are obtained using color filters that are backlit using just the right amount of pure white light.

There are four main components of the system: the DMD chip DLP, which controls the mirrors the color of the wheel the luminous source and the optics to produce the image, the light of light passes through the filter of color wheel and DMD chip, which then switches your mirrors or off, according to the color that is reflecting off of them.

This digital light processing, DLP or technology is quickly becoming a major player in the world of rear projection TV, and were sold more than two million of these TVs. more than 50 manufacturers sell at least a DLP television model based, and in 2004 the DLP TV had achieved a market share of 10%. In addition, small standalone units, known in the company as front projectors, became popular items in the world of business presentations and in the world of cinema at home.

DLP technology advantages there are a number of important advantages to televisions that use DLP technology to produce their monitors. Some of these advantages include: images that are smooth and jitter-free without possibility of screen burn in good contrast good color depth for addition, DLP rear projection TVs are typically smaller, thinner and lighter in weight than traditional CRT TVs of similar size. Another potential advantage of the new DLP is that the light source is replaceable, which may be able to provide a longer lifespan than traditional CRT or plasma screen displays again. The DLP drive light source is much easier to replace than a LCD model and many models of DLP television feature light sources that are easily changed by the end user. Of course nobody wants to replace the light source before its time, and the LED light sources in the latest market, introduced in April 2006, were shown to last 20,000 hours before needing to be replaced.

Disadvantages of DLP naturally there are some disadvantages to DLP television technology too, and it is important for those in the market for a new TV to be aware of these potential pitfalls. For example, in some single-chip DLP designs, viewers can be inconvenienced by the so-called "rainbow effect," which affects how colors are displayed on TV and perceived by the Viewer.

In addition to this rainbow effect, some possible disadvantages of DLP include: not as thin or as elegant as LCD or plasma displays, even if the weight is comparable to some models have replacement lamps fans can be quite expensive, ranging from $ 200 to as much as $ 500 competing technologies the main competitor to the DLP on the market of rear projection televisions is known as LCoS (liquid crystal on silicon). This technology creates his images by using a stationary mirror that is mounted on the surface of a chip and then uses a liquid crystal matrix to control how much light is reflected to create the image. These competing standards are still being worked on, so it is important to buy with caution and read many reviews before making a final purchase.

When buying a DLP television, it is important of course to learn as much as you can about the new technology, and it's so important to shop around for the best price possible. When you buy a new DLP TV, it is important to review carefully the type of tuner that uses the drive. Many modern televisions are designed to be multisystem devices, meaning that not only are they capable of reading the NTSC signal used in North America and Japan, but they will also be able to deal with competing standards such as PAL and SECAM. This can be an important consideration, so it is important to make sure that you understand these various formats and how they affect you as an end user.

It is also important to look at the type of components that can be connected to the new DLP television. Most modern TVs are built to accept progressive signals not only TV boxes, satellite and cable TV, but also of DVD players, VCRs and even computers. The presence of a VGA or DVI connection will allow the unit to function as a computer monitor, as well as a television, but it is important to exercise caution when using any type of rear projection TV for this purpose. While plasma TVs can often make excellent monitors, technologies such as DLP can fight to provide the depth and resolution that computer users are used.

Even though the prices of televisions and DLP televisions in General in particular, have become much more accessible in recent years, these TVs are still great buys and it makes sense to give purchasing consideration it deserves. As with any purchase, shopping around carefully will help you obtain not only the lowest price, but also the best overall value.
