Issues with high-end HDTVs - Toronto Sun
If you re looking for a new HDTV and yes, that includes one of those gimmicky new 3D TVs you re going to be looking either at a plasma TV or an LCD TV. The two competing technologies have specific pros and cons, and it would be best to

One of the biggest drawbacks of the big screen television is the space needed for the television set itself. The plasma TV technology has made it possible to incorporate a big screen television into a small room. To understand how this change came about, briefly consider the difference in technology between a traditional television set and a plasma TV.

For the majority of time that television sets have been used as part of the home entertainment system, the television picked up a analog signal sent out by a broadcaster. That signal was analyzed by the television set and cathode ray tubes lit up the screen of the television. Thousands of tiny pixels make up the screen of the TV set in three colors - red, blue and green. Combinations of colors gave different hues as seen in real life and the result was a movie that (as nearly as possible) duplicated what we see in the real world. Digital television systems have increased the quality of the picture though many signals are still in analog form.

The plasma TV uses a different kind of technology for producing the picture though the reception is the same. In the case of the plasma TV, the pixels are lit up using something very similar to a fluorescent light. One of the biggest advantages is that the plasma TV technology uses much less space than the cathode ray tubes. This means that the plasma TV is only a few inches thick as opposed to the tube televisions that were large, bulky pieces of furniture.

This means that a smaller room that might not have been suitable for a big screen television set before could now have sufficient room. Because the screens are flat, you are also not dealing with the distortion at the edges of the screen and don’t really have to be directly in front of the plasma TV to get a good view.

What are Plasma televisions?

Televisions previous to the Plasma TV explosion used the (CRT) cathode ray tube to give users the ability to watch television. CRT televisions works by shooting out a beam of negative charged particles called electrons into a large glass tube. These negative electrons

For the past 75 years, the vast majority of televisions have been built around the same technology, the cathode ray tube (CRT). In a CRT television, a gun fires a beam of electrons (negatively-charged particles) inside a large glass tube. The electrons illuminate phosphor atoms inside the tube (screen), this allows the TV picture to be produced by illuminating different areas of the phosphor coating, this is what gives you the CRT television.

Now welcome to the new face of television, Plasma TV. Plasma has taken the home theater market by storm because of their amazing picture quality and very thin design. The idea of plasma display panels began in 1964 at the University of Illinois. The first displays were very primitive using only points of light created in the laboratory. As time went on digital processing, and other technology, made vivid plasma displays a reality.

Plasma televisions use a much different type of technology thatn CRT models, they use something called pixels. Using a video signal the pixels on the flat screen light up with a high-energy beam of electrons that are separated into the 3 primary colors, red, green and blue. From the illuminated fluorescent lights pixels you get the full color spectrum that produces a full range of colors that give you the image on the screen. Each pixel on the screen has three fluorescent lights in it, a green, red and a blue fluorescent light. Each fluorescent light in the pixel can produce 16 million colors, giving you amazing colors and overall picture quality that you can’t finder in regular CRT televisions.

Another feature that you can’t find in CRT TVs is the widescreen design found on Plasma televisions. The (16:9) aspect ratio is the same dimensions used in movie theaters. This feature gives Plasma flat screen high definition television models a cinematic feel, that is great for watching feature films, concerts, Monday Night Football or anything else you can imagine.

And unlike conventional television models, there are no scan lines on plasma televisions, so the picture is much sharper. The viewing angle is far superior than CRT, there is 170 degree viewing angle so you can basically watch the TV from any area in the room. As I mentioned before Plasma Tvs are very thin, only 3.3 inches in width. This makes them perfect for hanging on your wall, freeing up space in your home. Just like a picture frame, you can now hang your television on your wall!

So who manufacturers these thin TV displays? You can choose from numerous brand names which I’m sure you are familiar with such as, Sony, Sharp, Hitachi and Samsung to name a few. Plasma isn’t the only technology available if you are a HDTV buff, you should also check out LCD televisions and rear projection TVs.

And if you want to find a cheap plasma TV, check out the discount deals available through internet, particularly Amazon.com and Ebay.com. Those 2 online merchants are trusted and can offer not only new, but used and refurbished models for even bigger savings.

Plasma TVs are the hottest thing in home entertainment, offering a crystal clear image with high quality resolution. The monitor is often less than a few inches thick, so it doesn’t need as much space as its traditional counterparts. It uses less electricity than a regular television and, unlike the old CRT TVs, there is no image disturbance if the monitor is placed near large speakers.

But with so many plasma TVs on the market, how do you know which is the best one to buy? Firstly, you should decide on your budget. Knowing how much you have to spend will definitely be a good place to start. Plasma TVs generally start at around $700.00 and can go as high as $4,000.00, so it’s important to know what you can afford before you start shopping.

Once you’ve worked out how much you want to spend, you need to decide whether you want your new plasma television to consist of more than just a plasma display or if you want it to have a TV tuner, as well. The pricier plasma TVs will have a tuner attached to it, while more modest versions will have a separate tuner box. Some models will come with their own speakers, allowing you to listen to your favourite programs, in Nicam stereo.

You should also try to make sure that the model that you choose runs quietly. Some models are known to be very noisy, because they often rely on fans for a cooling system, which can ruin your home entertainment experience. The good news is that many new models have been re-designed so that they do not need fans.

With the proper planning, you should be able to find the perfect plasma TV to fit your budget, which will last you for years to come.

Plasma TV has become an important part of television technology. Over the past few years, there have been several major advances in the industry, including the plasma TV. As with any major technology advances, the plasma TV is quickly becoming more affordable - good news for the consumer.

There are several reasons the price of the plasma TV is becoming more affordable. The first is the same reason that most technologies come down in price - the fact that the technology becomes more widely understood and available. As more manufacturers go into business to make the product, the competition naturally gets more intense and prices go down.

Remember that the manufacturers of those first units are trying to recoup the cost of research and development. That makes the product - in this case the plasma TV - more expensive for the consumer. After the technology is slightly older, the companies who manufacture are no longer trying to recover those costs so they can sell the products cheaper. As long as a person holds a patent and other companies are not able to reproduce the technology, the price is more likely to remain high.

Another point that affects the cost of new technologies such as the plasma TV is simple supply and demand. As more consumers demand the product, more manufacturers will go to the expense of making the product available. At first, there won’t likely be sufficient supply to meet the consumer demand but that typically changes after an initial introduction period. When there are plenty of plasma TV sets available to meet current demand, prices will drop.

For the consumer, this means that great technology - the plasma TV, for example - becomes more affordable in a relatively short period of time. Finding a great deal on a plasma TV should be as near as your online or local retailers.

A Plasma HDTV or a LCD Television Is this your dilemma? This is a rather difficult and complicated comparison between two technologies that process the image in a totally different manner.

This article highlights the pros and cons of plasma versus LCD as applicable to a television display. It also presents a set of guidelines to help you determine where either of these two flat panel display technologies fit best.

Plasma or LCD Which type of display is right for you?

Though both LCD and plasma displays come in the form of slim flat panel displays, yet from a technology perspective, these two flat panel displays process the image in a totally different manner.

Plasma uses a matrix of tiny gas plasma cells that are charged by precise electrical voltages to emit light and hence to create the picture image. Liquid Crystal Displays (LCD) panels - work by trapping a liquid crystal solution between two sheets of polarized glass. When an electric current is passed through the liquid crystals, they change the polarization of the light passing through them in response to the electric voltage as a result of which, more or less light is able to pass through the polarized glass on the face of the display.

It is not the scope of this article to go into the actual details of how these different display technologies process the image after all, what really matters is not what is going behind the screen but rather how these different display technologies perform as a television screen. At the same time, it is worth taking note that it is these same differences that gives each of these display technologies, its strengths and weaknesses, and that therefore renders one more suitable than the other in certain circumstances.

The list below highlights the most important differences between these two flat panel display technologies:

Size: For the time being, collision between plasma television and LCD TV occur in the 40 to 50 inch screen range. In reality, LCD TVs top out at around 45 meaning that for bigger screen sizes, a plasma display is your only real option if what you are after is a direct-view TV system. On the other hand, at the smaller end of spectrum, namely 15 to 36 TVs, LCD is the way to go if what you want is something stylish and slim (at under 4-inches in depth).

Picture Quality, Contrast and Color Saturation: Both plasma and the latest TFT-LCD flat panel displays are capable of producing excellent picture quality with bright, crisp clear images.

However, plasma flat panel displays are more suitable for basic home theater usage than LCD. The gas cell structure within a plasma display is such that there is no light leaking between adjacent cells (or pixels). This renders plasma displays capable of displaying deeper blacks hence better contrast and detail in television and movie scenes where lots of dark and light content is shown simultaneously.

In comparison, the nature of LCD technology where a backlight shines through the LCD layer means that it is hard for it to achieve true blacks (i.e. true absence of light) as there is always some light leakage from adjacent pixels.

This does not mean that LCD panel s are not suitable as TV screens; todays LCD TV sets make use of extreme high contrast panels that are capable of displaying deeper blacks, yet the latest plasma TV sets still have a slight edge over LCD when it comes to contrast levels.

The situation is somewhat similar when it comes to color saturation. Again, it is the different display structure between LCD and plasma that is the reason behind the difference between the two technologies in this respect, and though both are capable of handling color in an exceptional manner, yet plasma displays still lead in this respect - producing more accurate and vibrant colors.

Viewing-angle:Plasma Television sets like their CRT TV counterpart - typically have better viewing angles than LCD. The viewing angle represents how far one can sit on either side of the screen away from the center, without experiencing significant deterioration in picture quality mainly as a result of color shifts and reduced contrast.

Though recent developments in LCD technology means that this is less of an issue with some of the latest LCD TV sets boosting a viewing angle of 160 to 170 degrees vertically and horizontally, yet it is always best to check. The tendency especially with cheaper sets is that the deterioration in picture quality is more accentuated with LCD than with plasma displays.

Burn-In: As with all phosphor-based displays, plasma displays are prone to burn-in, or image retention. Screen burn-in occurs when an image is left for too long on the screen resulting in a ghost of the image burned on the screen. Surely, keeping the brightness and contrast levels down will help reduce the risk of burn-in.

While some brands of plasma displays are more prone than others to burn-in, yet in general, plasma screens are more prone to suffer permanent burn-in during their first 200 hours of use; the reason being that fresh phosphors burn more intensely as they are ignited.

Technically speaking, burn-in is the result of a damaged pixel, whose phosphors has been prematurely aged and therefore glows less intensely than those of surrounding pixels. The presence of a static image for more than half-an-hour is enough to cause temporary burn-in; temporary burn-in or image ghosting, should not be cause for alarm as normally this will wash out after several hours of use.

Worst still is the prolonged presentation of static displays, such as the use of black or gray bars to view a 4:3 picture in its original format on a wide screen display; this will result in a permanent burn-in. Once permanent burn-in occurs, the damaged phosphors cannot produce the same levels of light output as the other phosphors around them do.
In these circumstances, an LCD display may be a better choice.

Viewing distance: It seems that the pixel size and shape of an LCD panel renders a smoother picture than an equivalently sized plasma panel for the same pixel count.

This means that even if your viewing distance falls within the recommended distance of approximately twice the screen width, if this is less than at least nine feet, most probably you will be better off with an LCD TV.

Life-time: The rare gases used in plasma display panels have a life and will fade over use. Earlier plasma TV sets had a quoted half-lifetime of between 20,000hrs, following which the image brightness will fall to half its original value. However, the latest plasma displays can boost anything between 30,000 and 60,000 hours. On the other hand, LCD displays have a guaranteed lifetime of between 50,000hrs and 60,000 hours. This degradation in image brightness takes place gradually over time.

Now, the average household in the US replaces their TV set every 7 years. Taking a conservative figure of 30,000 hours for either technology, this corresponds to well over 6hrs usage a day - every day - for over a period of 14 years! In other words, both plasma and LCD displays are extremely stable and reliable devices. This means that life-time should not be an issue with either display technology.

At the same time, keep in mind that there is no way to re-generate the gases in a plasma display or to repair any dead pixels in an LCD display the only option in such circumstances will be to replace the display.

Response: Some LCD panels especially on older generation models - had a tendency to blur images particularly during fast moving scenes in movies and sports. However, recent advancement in LCD technology means that response times are such that there is no noticeable difference in performance between LCD and plasma TV sets in this regard.

Power requirements: The advantage here goes to LCD panels as these consume less electricity. Estimates show that the use of LCD panels can result in some 30% power savings for the same screen size than plasma display.

Price: Price is always a big issue when it comes to choosing your TV display. Although prices online vary considerably, yet LCD TV sets tend to be more expensive than Plasma Televisions. The main reason behind this price gap is that the production process for plasma technology still supports a better yield and thus carries a pricing advantage especially at the large screen end of the market.

This contrasts heavily with LCD display technology where an estimate 30 to 40 per cent of all manufactured panels will have to be discarded as a result of defects leading to what are known as ‘bad-pixels’.

Making the Choice:

There is a market for both plasma and LCD displays - Plasma gives you a bigger screen for your dollar, deeper blacks, but then LCD do not suffer from burn-in and at the smaller end of the market (less than 40-inch screen size), LCD is your only way forward if you want something slim and stylish.

It is all a question of knowing what are the advantages and limitations of each with respect to your specific needs.
