Obviously price variations of LCDs would be on the screen from size, differences in display quality, resolution, and a number of other factors, including but not limited to the brand. LCD TVs are now in ever-lower prices, and the smaller units are as low as two hundred U.S. dollars is available with several retailers. But in the upper area still running into tens of thousands of dollars and get the largest LCD displays for home theaters at steep prices.

A majority of theIts customers include the central region of 23 "to 40" screen size, which in general to almost $ 1,000 to just under 3,000 U.S. dollars. Some of the largest manufacturers of electronic products available TV with LCD technology such as Samsung, Sony, Sharp, Philips, Panasonic and Toshiba, and computer maker Dell have taken an interest in this area and have a model that builds has come quite a stir.

Although the TV with LCD technology is exorbitant, muchhigher than the normal tube models, there are several reasons that more money is paying off, the most important of which are listed below:

Totally Flat Screen:

Traditional CRT TVs have a curvature built into their screens and this could lead edge of distortion, as well as shadows on the screen. But this is not the case with the LCD screen is really flat surface in a position to remove any edge distortion and thus a more reliable and true-to-life offersDisplay.

Original widescreen performance:

The LCD TVs carry a widescreen aspect ratio of 16:9, which is more likely to appear like a theater than a TV screen. This means that the height of the screen 9 cm and the width is 16 inches, so that its length is almost twice the width that the viewer a feeling of being in a theater. The current HDTV signals, follow this aspect ratio, as well as widescreen DVDs and VHS videos.

Better Angle:

Unlike otherProjection TV technology, such as DLPs, LCD TV with a viewing angle of 160 degrees occur, and may be seen without distortion from any angle at all.

Everything you need to know about plasma television technology

Although in the last twenty years have seen great advances in the world of TV technology, it is the plasma television that has captured the imagination and attention of the masses. This technology has come a long way since July 1964 when it initially the result of a study by the University of Illinois. Thesetrue flat panel market with exorbitant price tags beyond the reach of all but the few rich individuals and corporations, as the original plasma screens entered relatively small size, and the raw materials were expensive in their production.

But technological progress is a great equalizer, especially in combination, though with declining commodity prices: the prices of plasma displays a number notches in recent years have fallen sharply, and moreappropriate today than ever before. Your strength and beauty in the form of color and picture quality is within reach of more and more middle-tier customers. Most known electronics manufacturers conduct high quality plasma televisions, and that would include companies such as Sony, Samsung, Panasonic, Zenith, Phillips and Sylvania.

The prices of plasma TVs are not what they have to be, and now economically, but they still cost a lot more than just a normal tubeTelevision. Most plasmas retail between $ 2,000 to $ 3,500, but shrewd purchases in the form of looking around, do research, looking for distribution and so on land, can you have a plasma TV for $ 1500 or less. You should know exactly what you want to pay the limitations and advantages of plasma technology, and what you are ready for it.

It will also be good at this point, that depends on the quality of a plasma television from a variety of factors, not the slightest recollectionit is the quality of the cables is with a hook. Compromising the quality of the cable to go save a few dollars, a lot to the plasma owners are not only long-term costs, but also in clearly discernible drop in performance from the beginning, even from the best model of plasma. You need to invest in the best quality and most reliable cable to hook up the plasma screen to different devices such as DVD players, VCRs, laser disc players, computers, laptops, and soon.

How does the technology function in a plasma TV screens?

A plasma screen consists of two thin plates of glass mounted together, and the core of the technology lies between these two panels with a network of small pockets of compressed gas to get to pixels or pixel form. Each pixel contains a triad of sub-pixels, in red, green and blue phosphors.

The uniqueness of a plasma television is the fact that the advanced electronics controlling the red,Green and blue sub-pixels can produce more than 16 million colors. If the sub-pixels with small electrical impulses activate the gases react, plasma shape, and they emit light that enters the red, green and blue phosphors to produce color in a display with high quality. Since all the excited pixels react simultaneously provides the viewer no flickering, and instead in a position on a bright display with a predominance of rich, realistic color with superior FestDepth and subtle color gradations.

Moreover, because it is a lack of a back-lighting or electron beam with the plasma TV, the viewer is able to enjoy a sharper, brighter and richer image to an ultra-slim flat panel displays. This comes together with a wide viewing angle are as high as 160 degrees without border distortions, as in the regular CRT televisions. On bare 4 "thick (some are even as thin as 3 inches) and weighing under 67 pounds for a 40-inch screen,Plasma TV is a combination of size, comfort and performance seldom seen before in the era of traditional CRT television technology.

Plasma TVs offer a much higher resolution than CRT televisions, and also equipped with the ability to function with various signals, including HDTV (high definition television), DTV (digital television) as well as XGA, SVGA and VGA signals from a computer.

The technology behindtraditional CRT screens requires an electron beam is used to scan the picture tube from top to bottom at regular intervals. In the course of playing a traditional NTSC signal, the viewer may be able to actually see these lines, but since a plasma television comes with built-in line doubling, this increases the image quality and distract the viewer is not visible scan lines before especially when viewing a standard analog signal like broadcast television of VHS tapes.

Plasmas also come withan aspect ratio of 16:9, which means that its length is almost twice as wide, more like a movie screen than a conventional television. This makes it one of the best choices for home theater, for widescreen DVD movies and HDTV programming look great on these displays, the observation of these displays is like in a movie theater, and provides a very good performance. Plasma technology is also superior rear-projection TV technology, which sometimes causesshown to have "hot spots" in the middle of the screen, or dark spots in the corners. Plasma TVs are completely free from all these problems, and a project uniformly bright image at all times.

But of course, is the most common cause of the growing popularity of plasmas, as they look. Their ultra-thin, futuristic design captures the imagination of potential buyers and nothing else. Bigger and bigger screen sizes to help with thinner and thinner body, as well. It canWall-mounted like a picture, and can always make you fit in a small apartment, so that the apartment itself features an ultra-modern look that is in stark contrast to the previous regular tube televisions, with their heavy mass.

Plasma TVs have a wealth of benefits for the potential buyer television, they have the look and performance they require so much in too. Falling prices over the years, they have more affordable than ever before: today, a plasma is used asa good investment of hard earned dollars for an avid TV enthusiast.
