LCD TV - 6 Reasons Why LCD Televisions Rock!

The LCD TV is really starting to come of age and while they have dominated the small screen market in recent times over plasma, it seems it may not be too long before they challenge their arch rival in the bigger screen areas.

In fact, proto type 55" LCD TVs have already been produced and if the progress continues to gather momentum they could very well challenge plasma in the area it is best known for - large screen televisions.

In this article, let's take a look at some of the advantages of an LCD TV and why you may consider one for you home over the next few months.

Advantages Of LCDs

The price of LCD has always been a drawback for most home theater enthusiasts. The money outlaid for a small screen television doesn't seem to make sense when for less, you can purchase a large screen plasma. As mentioned above, that scenario is likely to change rapidly.

As far as advantages are concerned, here are just a few:

- Very good viewing experience. They will handle any lighting conditions from a well lit room, an artificially lit room and even a small light such as that from a lamp. In other words, your picture wont attract that wash out effect or annoying glare.

- Viewing angle...yes, this was once a bug bear and was one of the advantages enjoyed by plasma but times have changed and you could now reasonably expect to be able to view your set from an angle of 160 degrees.

- The quality of picture is excellent, even life-like. Color is enhanced to incredible levels and makes the viewing experience pleasurable. It's almost as if the screen is conveying a smooth appearance and you won't see annoying lines in your picture.

- It is versatile. An LCD TV can double up as a computer monitor as well as providing input for just about any video format around.

- Very easy to set up even for someone who is technically challenged. Devices of an external nature are always challenging to someone with little technical knowledge but most LCD TV sets come with built in tuners.

- You will generally expect to get a minimum of 60,000 hours of viewing time from your LCD TV. This was one of their big advantages over plasma although the latter is making up ground in this area in rapid fashion.

Plasma TV Comparisons - How To Find The Best Plasma TV

If you love television, and you love modern technology, there's no way around it - you've got to have a plasma TV! Here's an overview of plasma TVs, plasma TV features, and where to go online for plasma TV comparisons to find the best TV at the best price.

What is a plasma TV?

A plasma TV is a video monitor that uses millions of tiny colored fluorescent lights to create an image. The tiny light cells are sandwiched between two plates of glass along with electrodes that trigger the cells to produce colors and patterns. This innovative way of creating images allows plasma TVs to be both flat and very large.

What are the features of a plasma TV?

* Plasma TVs provide high-resolution images. The image quality of plasma TVs is much sharper and clearer than tube TVs. Because of this, plasma TVs can accommodate high-definition HDTV signals, as well as DTV, and other formats.

* Plasma TVs are easy to view from any place in the room. And unlike projection TVs and LCD TVs, the picture on a plasma TV is clear from almost any angle.

* Plasma TVs are completely flat. Not only are they attractive and modern, but there is no distortion from curvature, which can be a problem with tube TV screens.

* Plasma TVs are slim and lightweight. The construction of plasma TVs lets them be hung on a wall and hug the wall. You can put a plasma TV almost anywhere, in comparison with the limits posed by the shape and size of traditional tube TVs and projection TVs.

* Plasma TVs accommodate a widescreen format. You get the full theater experience from plasma TVs because they use a widescreen aspect ratio. In addition to their high resolution, this allows plasma TVs to make the most of HDTV and DVD formats.

* Plasma TVs are lifelike. The picture you get from a plasma TV is the clearest picture around, and there is such a sense of depth, the image almost seems three-dimensional.

Where can I compare plasma TV prices?

All this modern technology comes at a price - plasma TVs aren't cheap. Most start at $2,000 and can cost up to $10,000, depending upon the size and model.

In order to get the best price on a plasma TV, I recommend going to your local electronics stores to compare the prices and features, then compare prices online before you buy one.

I found an excellent online service that compares prices and provides customer reviews on all models and brands of plasma TVs. Not only does this service provide well-researched price comparisons for the various makes and models of plasma TVs, but it also gives ratings plus detailed product information.

Reviews of plasma TVs are provided by customers who actually own one. It's like having a network of friends to give you first-hand, unbiased advice on your plasma TV purchase. You can click on the links below to go to this service and comparison shop for yourself.

Clarifying The Technology Behind LCD Plasma TVs

Technology is an amazing thing. It constantly progresses. If you buy a new television set now, then in a few months or a year, the technology will be considered outdated.

It is hard to keep up with all of the options and developments with television technology, but if you have a base knowledge about LCD plasma TVs, then you will be ahead of the pack. Once you know the basics you will have a great start when it comes time to make your next TV purchase.

You may not care about the difference in technology between a cathode-ray television and the LCD plasma TVs. Most people really just care about the picture quality and the sound quality. It is not any wonder. A person can become mesmerized by the clear, crisp colors.

The smooth motions of the people on screen. The sound coming out of the speakers and you cannot forget about the slim design. But maybe knowing a little about the inner workings of these wonderful machines may be a good idea.

Each of the pixels in a new plasma flat screen television is controlled by individual specialized electronics. This technology allows for billions of colors. You get clear resolution, excellent picture color and no distortion, all while having a tv that is six inches thick.

Compare that to the huge, bulky models of the past. The kind of box that required three people to move it versus the plasma screen television that one person can carry.

The rage in technology during the 1980's and early 1990's was the big screen television. It stood about five feet tall and had a resolution that was atrocious. The picture, rather than looking sharp and crisp, was distorted and the colors were faded.

You do not have to sacrifice screen size in exchange for crystal clear picture and dynamic colors. You can get a 60 inch Plasma tv! It is big enough to feed your tv or gaming habit and still give you enough room in your living room for some furniture.

LCD plasma TVs are still relatively expensive when you consider the non-plasma or LCD models. But as more come out in production, the price will begin to fall. For a typical 30 inch plasma television, you can expect to pay around $800, depending on where you purchase.

Larger screens will naturally be more expensive and can easily top the $1500 mark. Much of the price depends on the size, model and where you buy your electronics. Larger retail stores will often be your best location.

How to Buy an Inexpensive LCD TV

Is it possible to buy an expensive LCD TV?

Liquid crystal display television (LCD TV) technology has come a long way in recent years. The implementation of thin file transistor (TFT) technology has removed many of the angular resolution and ghosting problems previously associated with cheap LCD televisions.

It is now possible to buy an inexpensive LCD TV that has state-of-the-art features and superior picture quality.

What is an LCD TV?

An LCD TV is a flat panel television that utilizes advanced materials technology to create a bright, attractive picture on a flat screen.

An LCD TV screen is made up of two glass plates with a thin layer of liquid crystals in between. When electricity passes through the crystals, tiny color pixels light up to produce an image.

How do LCD TVs Compare to Plasma and Tube TVs?

In the past, plasma TVs were the only real flat panel television option. Now, LCD televisions have progressed to the point where they can compete with plasma TVs in terms of picture quality.

LCD televisions are easier to maintain, less likely to degrade with time, and use less power than plasma TVs. And the new crop of LCD TVs have a sharper picture, require less space, and use much less electricity than tube TVs.

What are the Features of an LCD TV?

Here's a list of features found on newer model LCD TVs:

* Digital picture - the picture on an LCD screen is much sharper than on a tube TV and is now comparable to plasma TVs.
* Space saving design - LCD TVs are thinner and lighter than tube or plasma TVs, and can be set up almost anywhere.
* Widescreen format - LCD TVs utilize a widescreen format, similar to movie screens, so they are compatible with HDTV programming.
* Flat screen - LCD TV screens are flat, so there's no distortion as with tube TVs.

Where can I Buy a Cheap LCD Television?

The best way I've found to get the best deal on a television is to first check out various models at your local electronics stores and discount stores. After you get a good idea of what you want in a TV and what's available, go online and check prices and ratings at a comparison shopping site.

With the site I use I can compare various LCD prices and find out which stores are reputable and give good service. I can also get detailed product information, ratings by electronics experts, and even consumer reviews by people who actually own the product.

Forget about sales and discount warehouses. The best way to save money on big ticket items like LCD TVs is to comparison shop online. I've saved thousands of dollars on TVs, computers, appliances, and even furniture using this method (click on the links below for more information on the site I use).

LCD vs. Plasma Televisions: Choosing the Best TV for You

Want to enjoy technology at its best? Want a bigger and better TV? Learn more about LCD and Plasma TVs and choose the best for you.

You are ready and eager to move and keep up pace with the 21st century, and the 21st century is all about technology my friends. Move aside Discmans, here come ipods and MP3 players and move aside boxy televisions the sleek and sexy flat screen TVs are here to take over. And not just any flat screen TVs, its time for LCD and Plasma TVs.

If you thought LCD and Plasma TVs are one and the same, you are not the only one…many people think the two terms are synonymous. But they are not; there are few but distinct differences between both. First lets talk about the similarities between the two. The most important similarity and advantage is the fact that both are very very thin monitors, each is only a few inches thick. You have the option to place them on a stand or mount them on a wall, and they both produce high definition television programming. But this is where the similarities end.

LCD vs. Plasma: What they are:

So while comparing LCD vs. Plasma TVs it is best to understand what each one is. Lets start with Plasma TVs. A plasma screen is one that consists of millions of multi-colored gas filled cells and these emit a picture when electricity is passed through them to light them up. An interesting fact to know is that a Plasma screen TV has a higher resolution that Tube TV screens. Some people say that watching something on a plasma screen TV is like watching something in reality. There are a variety of ranges in Plasma Screens… from 42 inches to 65 inches wide and also the thickness can vary from 3 inches to 4 inches.

LCD or Light Crystal Display TV screens are made of a thin layer of crystals in a liquid form filled between two glass plates. An image or a picture is created on the screen when electricity is passed through the crystals in the form of tiny multi-colored pixels. LCD screens are lighter and slimmer than plasma screens and are more popular in computer screens but are fast becoming popular among TV screens as well. An LCD TV screen can be as slim as a quarter of an inch or as thick as four inches. The width can vary from anything between 2 inches to 65 inches.

Plasma vs. LCD: Features

This is where the real fun is, it is time to really compare the two TV screens and decide which is the best TV for you to buy. Here are the features and how the two screens differ:
Picture Quality: where picture quality is concerned, Plasma TVs are much better than LCD screens but this doesn’t mean that LCD screen TVs are bad, in fact they are getting better every day. The viewing angle of the Plasma TV is also better as compared to the LCD TV, and this proves it self when you place your self on one side of the TV and gauge the picture quality.
Screen Life: the screen life is estimated to be the number of hours before the picture starts fading. Plasma TVs have a screen life of 30,000 to 60,000 hours where as LCD TVs have more than 60,000 hours of viewing but this depends on the make and model of each TV. Be careful of ‘burn in’ in case of Plasma TVs. This is when the ghost of the image is burned into the screen. You need not worry about burn in for LCD TVs.
HD TV: High Definition signals of both Plasma and LCD TVs are great, but it is fair to say that LCD TVs have a bit of an edge over Plasma TVs in this field.
Video gaming: if you are inclined toward video games then it is best that you choose an LCD TV as this does not have the problem of burn in and is much better for gaming.
Portability: LCD TVs are much lighter and thinner than Plasma TVs, so in case of portability, LCD TVs win hands down.

Plasma vs. LCD TV: Price

Price is always a factor whenever you are buying any TV, but since Plasma TVs and LCD TVs are more technologically advanced the price plays a more important part in the final decision. Lets just say that price wise, an LCD TV is expensive than the Plasma TV but you can always compromise on size and fit your budget.

At the end of it all, both types of TV screens are the best that technology can offer you at the moment. Choose according to your needs and the depth of your pockets. Hope you have some happy TV time.

Why you should choose an LCD TV over a Plasma TV

When it comes to choosing which kind of TV to buy, whether it’s LCD TV or Plasma TV, consumers always have a hard time deciding. That’s why we will break down everything in order to prove to consumers that an LCD TV is the much better choice over a Plasma TV.

LCD TV and Plasma TV both represent the fast advancing technology that is offering viewers the best in Television viewing. But it doesn’t mean that one would cease to try to choose between these two, the better option with regards to quality and money.

There are certain advantages for both LCD TV and Plasma TV but at a careful analysis it has been proven that the LCD TV offers more advantages compared to the strong points of Plasma TV. Here are some of the finer points that the LCD TV has proven to be the better choice. Study each carefully and hopefully it will help you a great deal in choosing what to buy and answer your question “Why one should choose an LCD TV over a Plasma TV?”

Plasma TV started out with a little advantage over the LCD TV, but with the newer models of LCD TV, it has since catch up and overtaken Plasma TV with regards to picture quality and better contrast. The new LCD TVs now offers a much better color display than Plasma TVs and to add on to that, LCD TVs holds a sizable advantage with its resolution and therefore will offer a greater viewing experience compared to Plasma TV.

When it comes to using LCD TV for game consoles, LCD TVs hold the edge over Plasma TV by having a higher amount of panel resolution, the game images will look more lifelike and will result in a greatly detailed video gaming experience. Also, these advantages of the LCD will also make it possible for texts to appear more visible on screen than the ones in a Plasma TV.

Another clear advantage of LCD TV is the high resolutions that it possess. This provides a more stable image quality that will not cause eye fatigue to viewers even for extended viewing or long hours of watching shows on LCD TV. It is also proven that LCD TV’s boasts a much lengthy lifetime compared to Plasma TVs, a study proves that LCD TVs has an average life span of about 50,000 hours compared to the mere 30,000 hours of Plasma TVs.

But the biggest and most important advantages of LCD TV other than the picture quality and lifespan is the cost of LCD TVs compared to Plasma TVs. Naturally, one would expect a much better quality and lifespan for something more expensive but that is not the case with the LCD TV and Plasma TV. LCD TV even though it relatively costs a lot cheaper than Plasma TV, it also offers the best picture quality and possess the longer life span. With all these in mind, it’s obvious that LCD TV is the best choice over its Plasma counterpart.

Digital Signage: The Battle Between LCD and Plasma Panels Intensifies, and You are the Winner

A couple of research organizations recently released reports concluding LCD technology is now taking the lead in its competition with plasma displays to become the dominant flat panel display technology and will secure its position as the clear winner within a decade.

Let me state for the record, I have no favorite in this battle. But as an observer with a strong interest in the development of the digital signage market, I can only conclude that whether or not the reports are accurate, the stage is set for a battle royale that will drive the cost of flat panel displays lower and make digital signage a realistic economic proposition for a greater number of businesses.

The first report comes from market research firm iSuppli. The report, “LG, Samsung SDI Boost Market Shares in Q1 PDP Arena,” finds that despite a tight supply of plasma display panels in the first quarter of the year, the average selling price for plasmas actually declined. That’s not the way the law of supply and demand is supposed to work. Scarce supply with in a market with healthy demand should result in rising prices, not falling prices. What’s going on here?

Simple, according to iSuppli. The average selling price of plasma display panels fell due to intense competition from LCD panels in both the consumer and the business markets, which include digital signage applications. The research firm forecasts this trend will lead to a startling state of affairs in which plasma panel-related revenues will shrink from an all-time-high next year of $10.2 billion to $8.7 billion by 2011. Compare those revenue numbers to iSuppli’s forecasts of unit shipments. In 2006, 10 million plasma display panels were shipped. By 2011, that number will grow to 23.6 million units, yet annual revenue from their sale will be down by $1.5 billion. You don’t have to be a math major to figure out that unit prices will fall dramatically.

The other market researcher is In-Stat. It recently conducted seven end-user studies in North America, Asia and Europe to determine where the digital television market is headed. Granted, the TV market is a slice of the overall display market, but it’s a huge slice. The sheer size of the market has a significant impact on what display technologies get developed, which sizes become available and how much they cost.

According to In-Stat, LCD TVs will dominate the worldwide digital television market, racking up a 75 percent market share by 2011. The research firm also forecasts that plasma display panel TVs will account for only 15 percent of the overall market by then.

Just as the iSuppli research suggested unit prices will drop significantly for plasma display panels, the In-Stat findings suggest a pronounced decline in prices for digital TVs in general. The research firm forecasts that global unit shipments of DTVs will expand from 68 million last year to more than 144 million by 2011. However, pricing pressure will hold down revenues. In-Stat predicts DTV revenue will climb from $72 billion in 2006 to $76.7 billion in 2011 -less than a 5 percent increase on unit growth of more than 100 percent.

For business considering whether or not to spend resources on digital signage, these reports indicate the investment in the display portion of the equation is likely to be lower moving forward. Those savings can be used to better control and integrate those signs into the business’s overall digital infrastructure, to expand the number of panels in the digital signage network, to secure creative digital signage content, or simply be used for other purposes.

While the news from the market research firms may not be welcome in the halls of flat panel display manufacturers, it’s good new for business looking to elevate their communications through the use of digital signage.

LCD TV - The Latest In Viewing

Liquid Crystal Display is all about flat panel television technology. The technology of liquid crystal display has penetrated our everyday life in everyday things like wristwatches, mobile phones, calculators, computer monitors and high definition television. The use is growing rapidly and sales of LCD TV are expected to exceed 4 million in America alone.

There are some distinct advantages of LCD panels over other kinds of display technologies. They are slimmer and hardly go beyond 3.5`` in depth. These are lighter also and best of all they draw less power - only about 60% of the power consumed by plasma displays. LCD televisions do not spew electromagnetic waves that are harmful.

There are drawbacks of course - viewing angle is restricted, contrast ratio is limited and time of display response may cause concern. The biggest frown of all is caused by the price. Although it is falling but still it is considerably higher than its plasma counterpart.

LCD displays comprises mainly of sheets of polarized glass sheets - two in number. A liquid crystal solution is sandwiched between these. These liquid crystals are very specific that causes them to act as shutters that open or shut out entry of light as the need arises depending upon flow of electric current. This current passing through the liquid crystals is regulated by voltage that is applied between the glass sheets through the electrodes that are transparent. These form a network having rows on one direction of the panel and columns on the other side representing the pixels or picture elements.

What are these liquid crystals? Matter can be found in three states - solid, liquid and gas. Nevertheless there are substances that exist in a state that is neither liquid nor solid at any one point of time. The behaviour of these molecules is also peculiar. They keep to their orientation like those in a solid and yet they shuffle around taking up various positions like the molecules of a liquid. Thus these liquid crystals can be termed neither solid nor liquid though they have more of an affinity for the latter - that is the liquid state.

There are various types of liquid crystals with each having its distinct properties. Those used in LCD panels are termed nematic-phase liquid crystals. The molecules are arranged in a particular fashion having distinctive pattern.

LCD display systems are of two types - passive and active matrix. The former is more complicated, produces the best pictures and consequently the price also goes up. During the manufacturing stage bad-pixels pose a serious problem. Innumerable controlling transistors are required on the glass substrata to control each sub-pixel. A typical wide screen panel will require 3.1 million transistors. Any one faulty transistor cannot be replaced and are known as dead or stuck pixels. If one is permanently off then a black spot will show and if it is on then a white spot will show. If it crosses a certain number the whole unit will have to be discarded.

It was during the early 2000`s that LCD flat panels took over the television market from the typical CRT`s. The basis of the technology is founded on the characteristics of polarized light. The thin semi liquid crystal gel trapped between two slim polarized sheets is divided into pixels.

There is hectic activity to overcome the technological difficulties to make the set affordable. So the LCD TV has to be made affordable to hit the headlines of success.

Flat Screen TV Comparison: Plasma vs LCD

Flat screen TV is one of the most popular and exciting TV technologies today. At only a few inches thick, flat screen TVs offer unparalleled flexibility and convenience. Older conventional TV's, in fairness to them, did offer crisp and vibrant images. However, these TV's, which operate through a cathode ray tube (CRT), suffered from one major drawback, they were bulky. As screen size increased, so did the bulk and weight. However, the TV of old has reached its twilight years. New television technologies have enabled TV manufacturers to create TVs with wider screen size yet still only a few inches thick. Thus, flat screen TVs usher home entertainment into the 21st century.

Flat Screen TV basically refers to two technologies: Plasma and LCD. The advances in these two technologies have enabled TV makers to build thin, lightweight TV screens with a large picture area. Plasma and LCD both offer similarly large, lightweight, flat screen TV's but the similarities are skin deep for their inner workings are different.

Plasma or LCD?

Plasma and LCD TVs generally look similar however they use very different technologies. Plasma utilizes a grid of tiny cells of gas plasma that light up and create a picture when charged by precise electrical voltages. LCD (liquid crystal display) screens on the other hand are made of liquid crystals sandwiched between two glass plates and create images by varying the amount of electrical charge applied to the crystals. Both Plasma and LCD offer excellent picture quality. The following are their strengths and weaknesses and edge over the other.

1. Plasma screens can display blacks more accurately compared to LCD. Thus, pictures in a Plasma TV have richer contrast and better detail especially in dark TV and movie scenes. LCD TV's are catching up however.
2. Plasma TV has better viewing angles than LCD TV. How far you can sit on either side of the screen before the qualities of the pictures are affected is what the "viewing angle" is. In LCD TVs, brightness and color tend to shift when angled too far while that of Plasma TVs remain solid.
3. Plasma TV can produce brighter color while light leakages in LCD screens affect the color saturation.
4. Plasma TVs are priced relatively less than their LCD counterparts especially in the large screen segment. Plasma TVs offer much larger sizes than LCDs, yet are still priced lower.
5. LCD has a higher native resolution than plasma TVs of the same size. This results to sharper images and makes LCD TV the better choice for HDTV.
6. LCD TVs consume almost 30% less power than Plasma TVs.
7. LCD TVs are generally lighter than similar sized Plasmas.
8. Among the two, LCD screens have a longer life span than plasma screens. LCDs can last up to 60,000 hours compared to Plasma that average from 30,000 to 60,000 hours.
9. Plasma TVs are more prone to screen burn-ins compared to LCDs although newer plasma technology are less susceptible to these.
If you are looking for a large flat screen TV, Plasma TV is recommended. Plasma TVs can give you better value for your money. The price difference between Plasma TVs and LCD TVs is big. However, if you have money to burn, then LCD TV is the better choice especially if you want the sharpest images. For smaller flat screen TVs at the range of 15” to 36”, LCD is the way to go. Ultimately, both technologies are still evolving and new innovations and improvements are definitely in the works.

The Latest Deals On Lcd (liquid Crystal Display) Models

The large audiences that viewed some of the final football games of the season must have noticed that so many of the commercials were about either Satellite TV, or High Definition Television (HDTV). If you haven’t yet made the plunge, and can’t wait to go Hi-Def, and you don’t have a ton of cash on hand, I recommend looking at some of the latest deals on LCD (Liquid Crystal Display) models. The right LCD model can offer you picture quality that can rival some of the best Plasma or DLP (Digital Light Processing) sets and they can do it for less cost. Some of the sets in the 23 to 27 inch range are now selling for less than 1000 dollars and if you get the right model it can double as a computer monitor.

With LCD TV’s, there is no worry about the “burn in” problem that Plasma TV’s are capable of. It doesn't matter how long you leave an image onscreen, it won't leave an indelible image. The crystals are actually rods that spin in the medium in response to electrical stimulation. They then either block or allow light pass through, which is then filtered. The crystals act like a shutter in a camera, opening and closing thousands of times per second. Each pixel consists of red, green and blue components. These filter the light through each pixel and the image is seen on the screen. LCD TV’s are categorized as non-emissive displays, because the light source (fluorescents in the back of the set) shine through the filters.


LCD TV’s avoid the glare and reflection problems from room lighting bounced off the screen that Plasma TV’s suffer from. LCD’s have some problem reproducing deep blacks, but in some sets, it’s hardly noticeable. To find an HD set to use with a computer, check out units with 1,366 X 768 native resolution. Make sure that the model has an input for your computer. The two most common inputs for this are DVI and the older VGA.

LCD’s are thermotropic, which means they function better when it’s not too hot or too cold. Unless you are planning to mount your set in an igloo or outside in sunlight, this will not be a problem. And the response time problem that caused ghosting or trails on the screen, particularly during fast action scenes is less and less of a issue.

Your laptop’s screen is probably a LCD type system and power hungry backlights in your laptop are a main cause of the chronic problem of short battery life. But in the TV, they don’t consume much electricity relative to other televisions. And LCD’s are so light, especially the smaller ones, that they can easily be carried from to room if needed, or mounted almost anywhere.
