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 If you buy a new television set now, then in a few months or a year, the technology will be considered outdated.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.

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.

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.

Philips Unveils New 100 Inch Super-sized Philips Lcd Tv Prototype

Philips introduced its newest prototype LCD TV prototype in Berlin in September, the site of this year's IFA technology conference. Philips most recent foray into LCD technology offers four-sided Ambilight technology and measures an amazing 100 inches.

With high-definition TV on the forefront of future technology, Philips has truly created a cutting edge product. This 100 inch, super-sized LCD TV isn't only special because of its size, but because of its Ambilight technology, currently Philips' most innovative product.


Ambilight technology, called Full Surround in the new 100-inch LCD TV, refers to a special form of backlighting with colors that change according to the program material and its corresponding pixel colors, called pixel plus 3HD processing. Ambilight works by creating a multi-colored, glowing halo around the edge of the TV screen. This reduces eyestrain and makes the LCD screen seem larger than it actually is, ultimately creating a more realistic picture.

In the new 100-inch Philips LCD TV prototype, the Ambilight technology occurs on all four sides of the screen instead of the traditional two-sided Ambilight technology found on the current LCD TV's; thus the name "Full Surround."

The Ambilight technology offers numerous options, even a solid white light that reflects the light show without the need for a white wall behind it. The actual system proffers setting and controls, like color, action, ambience, and movie.

For example, color mode allows you to set the light to change with the colors on the screen or set it at one color; the action mode allows the speediest response, and you can adjust brightness of Philip's Ambilight LCD technology via a light sensor or manually, according to your preference

The picture on the new 100 inch super-sized Philips LCD TV prototype is clearer than ever, and will be widely coveted upon its release; the bad news is that it only exists as a prototype at the moment, and probably won't be available to general consumers for awhile. Philips has not yet offered a release or distribution date.

In short, the IFA was Philips' way of showcasing its new HD technology and giving consumers and resellers a taste of coming trends in HD technology. The 100-inch LCD TV cements Philips position as a leader in the flat-panel LCD TV market and one of the best producers of cutting-edge home entertainment systems. The Ambilight technology is the icing on the cake of a truly innovative, high-end product that promises a far more dramatic, immersive viewing experience than anything currently on the market today.

Two Fantastic LCD Flat Screen TVs To Be Proud Of From Samsung and Sony

It would appear that latest and most prestigious in house fashion accessory for the home is the Flat Screen TV. Of the many and varied types of Flat Screen TV available (and there are) which one do you purchase?
Liquid Crystal Display (LCD), Plasma, TFT what do you go with and purchase?

So an accurate definition of Digital TV and a Flat Screen TV is what? This is one of those areas where by and large ignorance rules and the wrong terms get used with amazing regularity such as LCD and Plasma both meaning the same thing when in fact they are similar yet different technologies.

The two main types of Flat Screen TV or screens available today are either Liquid Crystal Display (LCD) or Plasma. One of the major differences between the two technologies probably lies in the fact that with LCD TV?s because the main technology used is TFT (Thin Film Transistor) by and large the screens are able to be much more energy efficient and potentially much smaller and more mobile.

So lets get down to basics and start looking at individual TV?s.

The first LCD TV that we recommend that you take a look at here is the Sony KDL-32V20000

The KDL-32V20000 is a 32in LCD TV and the prices for these are around 1300 pounds sterling or 2600 US dollars. The resolution of the screen is 1366 X 768 and with regards to being HD ready the answer is yes. The Sony has 2 (2 RGB) scarts and and the type and number of multimedia interfaces the the Sony KDL-32V20000 uses are HDMI and 1. The type of tuner for this TV is Analogue and Digital and the KDL-32V20000 is available from a wide variety of outlets.

So given this information, what would be our view of the KDL-32V20000?

Well to start with our score for the picture quality is 10 out of 10 and closely tied in to the picture quality is the sound quality and our score for this would be 10 out of 10 Connectivity is important for most of these new media TV Sets and such our score would be 8 out of 10 If we take a look at the overall "featureability" our score would be 10 out of 10 and with regards to ease of use and overall value for money our opinion and score would be 8 and 8 out of 10 respectively.

Taking verything into consideration our overall view of the package would be this TV is very bit as elegant as the rest of the TV's from Sony and has a performance to match. The visuals are a joy to behold with good performances across the board. The audio is pretty damn good also and the speaker system give a performance that is almost unrivalled. OK the price is slightly more than contemporary units from other manufacturers but in this case we feel that this would be money well spent - always assuming that you had access to the funds in the first place.

The next LCD TV that we recommend that you take a look at here is the Samsung LE-32R87BD

The LE-32R87BD is a 32in LCD TV and currently these TV's can be found for 700 pounds sterling or 1400 US dollars. The resolution of the screen is 1366 X 768 and with regards to being HD ready the answer is yes. The Samsung has 2 (1 RGB) scarts and and the type and number of multimedia interfaces the the Samsung LE-32R87BD uses are HDMI and 3. The type of tuner for this TV is Analogue and Digital and the LE-32R87BD is available from a wide variety of outlets.

So to take an initial view how would we rate LE-32R87BD?

The most obvious place to start with as far as TV's are concerned would be the picture quality and our score here would be 10 out of 10 next we would look at the sound quality and our view of this would be 6 out of 10 Taking a look at the number of relevant connections and their availability, our score would be 10 out of 10 Overall with regards to the actual "featureability" of the set our score would be 10 out of 10 and the final individual verdicts would relate to the ease of use and overall value for money and our scores here would be 8 and 10 out of 10 respectively.

The overall verdict would be that this TV is great value all round. The design and performance marks it as yet another great TV from Samsung

Two of the Best LCD Flat Screen Tvs Available Currently From Toshiba and Humax

It would appear that latest and most prestigious in house fashion accessory for the home is the Flat Screen TV. Taking price and money out of the equation which type of Flat Screen TV do you purchase?

OK are you going to go with a Plasma TV (older technology, been around since 1964) or do you go with Liquid Crystal Display (LCD) for the Flat Screen TV?

So how would you describe Digital TV and how would you describe a Flat Screen TV? Well the short answer is that phraseology is mixed here and quite often people get confused, LCD, TFT and Plasma are all terms that get bandied around yet they don?t all mean the same thing.

In a nutshell Flat Screen TV?s can either be Liquid Crystal Display (LCD) sets or can be Plasma screen but the two are different. One of the major differences between the two technologies probably lies in the fact that with LCD TV?s because the main technology used is TFT (Thin Film Transistor) by and large the screens are able to be much more energy efficient and potentially much smaller and more mobile.

So lets get down to basics and start looking at individual TV?s.

The first LCD TV that we recommend that you take a look at here is the Toshiba 37WLT66

The 37WLT66 is a 32in LCD TV and these TV's at present can be found in the region of 1200 pounds sterling or 2400 US dollars. The screen resolution is 1366 X 768 and with regards to being HD ready the answer is yes. The Toshiba has 2 (1 RGB) scarts and and the type and number of multimedia interfaces the the Toshiba 37WLT66 uses are HDMI and 2. The type of tuner for this TV is Analogue and Digital and the 37WLT66 is available from a wide variety of outlets.

So given this information, what would be our view of the 37WLT66?

Well it is a TV after all and as such the logical place to start would be the picture and our score here would be 10 out of 10 as the other half of the "Sound and Vision" double act our opinion of the sound quality would be 8 out of 10 With regards to the availability and number of relevant connections, our score would be 8 out of 10 If we take a look at the overall "featureability" our score would be 10 out of 10 and for ease of use and overall value for money we would give the 8 and 10 out of 10 respectively.

Taking verything into consideration our overall view of the package would be the picture quality of this TV is extremely high (as you would expect being the sister TV to the 37WL66) and the Digital Tuner provides really clear pictures for those who don't believe in any form of Cable or Satellite subscriptions. It has to be said that overall this is an extremely good TV.

The next LCD TV that we recommend that you take a look at here is the Humax LP32-TDR1

The LP32-TDR1 is a 32in LCD TV and the prices for these are around 800 pounds sterling or 1600 US dollars. The screen resolution is 1366 X 768 and with regards to being HD ready the answer is yes.

Working Of A Plasma TV

Television technology for the past 75 years has been based on the technology of CRT or cathode-ray-tube. In it there are guns that fire beams of electrons, which are particles that are negatively charged inside a tube, made of glass. These electrons cause excitement in phosphor atoms located at the screen end or the end of the tube that is wide. As a result the phosphor atoms gets lighted up. The phosphor coating being lighted up on different areas with various colours with dissimilar intensities produces the image on the screen.

The images are sharp and vibrant but the sets are bulky. Thus a big screen will result in a television set that will take up a good size of the room! With necessity being the mother of invention, this difficulty has led to the popping up of a new technology leading to plasma flat panels for display. These sets have wide screen but are only a few inches thick.

A video signal lights up thousands of dots inside the monitor or television. These dots are known as pixels having highly energized electron beams. Usually pixels have three colours - blue, red and green. These are evenly spread out across the screen. Combining these basic colours in different proportions produces the entire colour show. The fundamental idea of the plasma unit is to light up minute coloured lights that are fluorescent to create the image. Each pixel comprises of three of these lights - red, green and blue. Similar to the CRT, the plasma television alters the intensity of the various lights to bring about the effect of the full spectrum of colours.

The first generation of plasma displays did not have tuners that receive the television signal and interprets that to make a video image. But today digital tuners have been assembled to the main unit.

Plasma is the central element in the fluorescent light. It is a gas that has free flowing ions and electrons. Ions are atoms that have been electrically charged and electrons are particles that have been negatively charged. Normally a gas is made of uncharged particles. Thus a gas atom usually has equal number of protons and electrons atom resulting in zero total charge. But the scene rapidly changes with the introduction of free electrons in the gas. This leads to the setting up across it of electrical voltage.

Free electrons clash with the atoms dislodging other electrons. When an electron goes missing the atom loses its balances. It becomes and ion. In the case of plasma there is electric current passing through. This causes particles that are negatively charged to rush to that region of the plasma that is positively charged; on the reverse the particles, which are positively, charged hurry towards the area that is negatively charged.

There is a mad rush and one collides into another constantly. The gas atoms in the plasma get excited. Photons of energy are now released. The atoms used in plasma displays are neon and xenon atoms. The gases of these are contained in thousands of tiny cells sandwiched between two glass plates.

Thus to sum up we find that the Plasma TV forms a picture from plasma or gas that is filled with atoms of xenon and neon as well as innumerable electrically charged electrons and atoms that bump and collide to release energy or power. The net result is that without extra bulk, the viewing area gets enlarged. Rather than being fat the Plasma TV is slim and thin. The quality of picture is par excellence but the draw back is that the cost is beyond the reach of many people.

Maximize Your Flatscreen TV Purchase

Plasma flat screen television technology seems cutting edge and brand new, however it was first developed in the 1960s. Once considered out of reach of the average consumer, They certainly have become much more affordable since the technology has become easier to mass produce.

The modern version is fast becoming a staple in home theaters and is often accompanied by additional high-tech accessories such as surround sound speakers. The feeling of sitting in a movie theater is replicated pretty accurately in a home theater that features a good flat screen plasma tv can offer. The largeness of the screen and the superior colors and picture quality all contribute to this effect.

These pieces of technological prowess owe their amazing color to unique technology that utilizes neon and xenon gases. These inert gases move between two flat glass panels and are completely safe. They produce over 16 million colors including a perfect black, which enhances the cinematic quality of the picture.

One way to measure the longevity of a plasma flat screen television is the number of hours to its half life, which occurs when the quality of the picture is reduced by half. Most have approximately 60,000 hours to half life. An excellent warranty that includes free or low-cost service will contribute to full enjoyment of every hour.

Even though the screen is much larger than the typical cathode ray televisions on the market, most of your models are approximately four inches deep. The thinness of the device allows a great deal of flexibility in determining where to install it. When mounted on the wall it can save a great deal of space.

However, with all the advantages of this technology, it is extremely delicate. This should be considered when placing your flat screen plasma tv in the home. Even small bumps can cause unexpected problems in screen quality and if a repair is possible it can be quite expensive. Parents should consider installing one so that it is high enough to avoid flying toys and rough housing children. Wall mounts that tilt are available so that they can be angled down if installed high on a wall.

As they become more widely available, specialized furniture, cabinets and stands have also come on the market. These accessories are available to match the personal style of every plasma owner. Home entertainment cabinets made from classic hardwoods can hold plasma flat screen televisions in addition to other equipment.

Those who favor contemporary decor can find metallic stands with glass shelves. Consumers may also utilize existing tables and cabinets. Regardless of what furniture is chosen to house one, it should be particularly sturdy. The delicate nature of these fine televisions mean that it cannot be bumped and it definitely must never fall off its stand. Even though the cost of plasma flat screen televisions is coming down, they are still not cheap. To safeguard this investment all mounts and surfaces should be fully tested to hold more than the weight of the television itself.

Budgeting considerations for your purchase should include the cost of the unit itself, any needed furniture and accessories, any warranties and the effect on the homes electric bill. Todays larger versions use a lot of electricity. However, this technology is constantly evolving. In the near future, consumers will have access to more energy efficient models.

The way that technology changes so quickly nowadays you would be wise to consider carefully any investment and try and ensure that it remains compliant with all possible standards.

The latest telecommunication system for broadcasting moving pictures and sound is known as Digital television (DTT) and as the name implies this relies upon the transmission and reception of digital signals as opposed to the more conventional analogue formats. With DTT, viewers are limited to whatever channels the antenna picks up. Signal quality will also vary.

The purpose of this article is to take a look at what is on offer with the new generation of Flat Screen Televisions available and in this case the television in particular is the Panasonic TH-50PX600.

The TH-50PX600 is a 50in Plasma TV and currently these TV's can be found for 2600 pounds sterling or 5200 US dollars. The resolution of the screen is 1366 X 768 and with regards to being HD Ready the answer is yes. The Panasonic has 3 (2 RGB) scarts and the type and number of Multimedia interfaces the TH-50PX600 uses is HDMI and 2. The type of Tuner for this TV is Analogue and Digital and the Panasonic is available from a wide variety of outlets.

So given this information, what would be our view of the Panasonic TH-50PX600?

Well to start with our score for the picture quality is 10, next we would look at the sound quality and our view of this would be 10. Another useful aspect to review is the availability and number of relevant connections and our score here would be 10. As far as overall features are concerned we would give it 108 and the final individual verdicts would relate to the ease of use and overall value for money and our scores here would be, 8 and 8 respectively.

Taking everything into consideration our overall view of the package would be One of the best we have seen. This Plasma TV is, as one critic described "one if the best I have ever seen" and the overall combination of terrific pictures, amazing sounds and for it all, a great price makes this combination very hard to beat, if not impossible.

It is extremely unlikely given the variety and range of makes and models available that you will not be able to find something to match your tastes or budget. The choice, as they say, is completely down to you to decide whether to stay at the forefront of what are rapidly changing technologies and fashion or to remain part of the safer but perhaps better developed mainstream. Either way we hope that by reading this short article you should have a slightly more informed view of the options available to you

Differences betwen LCD and Plasma TVs

Plasma and LCD panels may look similar, but the flat screen and thin profile is where the similarities end. There are a number of significant differences between the two.

Let us understand the meaning of Plasma and LCD Televisions in order to better understand the differences between them.

LIQUID CRYSTAL DISPLAY TELEVISION (LCD TV).

LCD TV uses LCD technology for its visual output. Liquid Crystal Display or LCD is a thin, flat display device made up of a number of color or monochrome pixels arrayed infront of a light source or reflector. In color LCDs each individual pixel is divided into three cells or subpixels which are colored red, green and blue. Each cell or subpixel can be controlled independently to yield thousands or millions of possible colors for each pixel. LCD TVs can make for excellent High Definition TV viewing.

LCD TVs - The Good

1. Excellent Color Reproduction - LCDs can display millions of colors accurately.

2. Multi-functional - LCD TVs have a plethora of connectivity options. They typically include inputs for composite video, S-video, High Definition Multimedia Interface(HDMI) and PC In.

3. No Burn In - With LCDs there is no problem of Burn In. Some TVs that rely on phosphors such as Plasmas and CRTs can experience Burn In where ghost images are permanently burned into the screen.

4. Inherently Progressive - LCDs use millions of tiny transistors that can be individually controlled by the "brains" inside the display. So LCDs can easily handle progressive-scan sources.

5. High Resolution - LCDs can display High Definition content with resolutions of 1366x768. The highest resolution achieved in a LCD is 1920x1080. 1080p is also called Full High Definition whereas 720p is called High Definition.

LCD TVs - The Bad

1. Expensive - LCD TVs are great but they are not cheap. LCD TVs cost more per inch than plasmas.

2. Poor Reproduction of Blacks - LCD TVs tend to produce grays, not blacks.

3. Limited Viewing Angle - LCDs have typically poor viewing angle. However, there has been a drastic improvement on this front with latest LCDs achieving a wide viewing angle of 178 degrees.

4. Slow Response Time - LCDs have longer response times than Plasmas.For example, when moving the mouse too fast on an LCD, multiple cursors can sometimes be seen. This is also known as Ghosting Effect. But this problem seems to have been addressed with the latest LCD TVs with response times as low as 8ms.

5. Low Contrast Ratio - Contrast Ratio is the ratio of the intensity of the brightest bright to the darkest dark. LCDs comparitively have lower Contrast Ratios than Plasmas.

PLASMA TELEVISION

A plasma screen contains literally millions of gas-filled cells (each one acting as a single image pixel) trapped between two pieces of glass. An electrical grid zaps these cells and causes the gases to ionize (and ionized gas is plasma - hence the name). The ionized gases, in turn, cause a layer of phosphor on the viewer's side layer of glass to light up. Plasma TVs combine a thin, compact chassis with a truly large screen size. Despite their compact dimensions Plasmas are available in 42+, 50+ and even 60+ inch sizes.

Plasma TVs - The Good

1. Excellent Brightness - Plasma TVs don't rely on a light bulb shining through or reflecting off of something (as an LCD or DLP system does). Plasma brightness is even better than CRT's in some ways because the picture is evenly bright across the entire screen.

2. High Resolution - The finest plasma TVs have such high resolutions (and such smooth images) that they look life like.

3. Progressive in nature - All the pixels on the screen light up simultaneously. You can have progressive HDTV sources (such as 720p) and non-HDTV sources (such as progressive-scan DVD players) displayed to full advantage on a plasma HDTV.

4. Wide Viewing Angle - Plasmas have a wider viewing angle as compared to LCDs. Plasma displays have a good picture even when you're sitting "off axis" (not perpendicular to the screen surface). This is a huge benefit for smaller rooms, where viewers may sit relatively far off to the sides of the screen, at wider angles.

Plasma TVs - The Bad

1. Burn-In - Plasmas rely on phosphor to display video. This can cause Burn-In where ghost images are permanently burned into the screen.

2. Short Lifespan - Another phenomenon of any phosphor-based display system is that eventually the phosphors "wear out" or lose their brightness. This is a subtle and slow process, but it inevitably happens.

3. Less-than-perfect color reproduction - Although plasma displays can produce a breathtaking array of colors, a lot of sets have the unfortunate tendency to make red colors look more orange than true red.

4. Poor reproduction of black - Plasma TVs fall short in the realm of reproducing black images. Most plasmas do slightly better job than LCD TVs at black reproduction, but they fall short of CRTs and some projection systems.



Other factors such as pricing, weight, power usage, high altitude performance and transportation are other considerations that apply on a person to person basis. So I will briefly just state the overall differences in these areas.

Pricing: Plasma TVs are still significantly less expensive than LCD in sizes over 32".

Weight: LCD TVs are considerably lighter and as such easier to mount and install. So… Plasma TVs will almost likely require a professional installer.

Power Usage: LCD TVs use on average half of the power Plasma TVs use

High altitude performance: High altitudes can affect the performance of plasma TV displays because the gas held inside each pixel is stressed, and has to work harder to perform. So……LCD TVs are better at high altitude (6500 feet and above).

Transportation: LCD TVs are lighter and far less fragile than plasma displays making shipping easier and less expensive.

Because technology in both Plasma and LCD TVS is advancing rapidly we may find some of these differences (such as size) very minimal in the near future.
