Tom Pretty asked:
Flat screen TVs are now commonplace in many homes. The most popular forms of these televisions are plasma and LCD. But as a consumer which can be considered the best choice? Hopefully the following article will highlight some of the fundamental differences between the two technologies and how this affects the buyer.
First and foremost it is important to understand the different processes involved in both plasma and LCD technology. While these types of TV may look the same, within there are completely different processes at work producing an image. Apart from both being thin and attractively styled, they have few similarities.
A Plasma TV utilises a system of miniscule plasma gas cells that are charged by electrical current to create changes in UV light. This light is then filtered through phosphorus gasses of each primary colour to make an image. LCD TV screens on the other hand resemble an electronic sandwich, with liquid crystals between two ‘slices’ of glass. Once again varying electrical current is applied to the crystals in order to create an image.
One of the major benefits that LCD TVs have over plasma variants is native resolution. This industry term simply refers to the number of pixels on the screen and in this particular instance means that LCD TVs have a higher resolution in terms of pixels than plasmas of a similar size.
One of the most touted benefits of LCD TVs is that they consume far less power than plasma varieties. This has become an increasingly important point in recent months as EU directives on energy consumption have come to the fore in electronic companies’ thinking. It is estimated that some models of plasma TV used thirty percent more power than a LCD of a similar size; the result has been some commentators labelling plasma TVs as the four by fours of the home.
It is also evident that LCD screens tend to have a longer lifespan than plasma models. Early models apparently lose half of their brightness after a measly twenty thousand hours although the latest varieties boast a lifespan of thirty to sixty thousand viewing hours. On the other hand, the average LCD TV typically has a guaranteed sixty thousand hour lifespan.
Screen burn is one of the more commonly highlighted problems with plasma TVs although this is becoming less of an issue. That said, even modern plasmas do suffer from screen burn, a result of a continuous image being shown on the screen and leaving a residual ghost image when viewing other channels. LCD TVs do not suffer from this problem at all.
So which should consumers buy? LCD or Plasma? This decision depends upon the size of the screen. In the majority of cases plasma TVs are better in larger sizes, for example those above fifty inches whereas LCD variants are better in smaller sizes. That said, those with an environmental conscience will be easily swayed by an LCD due to their lower power consumption and subsequent ecological validity. Additionally the longer lifespan of LCD televisions make them a better value buy although this is really a minor consideration. Ultimately the choice is down to the consumer but with plasma TVs apparently on the wane it is understandable that more people will see the benefits of LCDs in the future.

Stan Morse asked:
External looks are decidedly deceiving when you are standing on the showroom floor looking at the two side by side. Both of the televisions are flat and thin, but they use different engineering to bring you the same results.
How a Plasma TV Works
Plasma TV engineering use the same basic technology as the fluorescent light bulb. The screen is made up of of cells. In each cell two glass panels are set-apart with a thin gap filled with neon-xenon gas and then sealed in the form of plasma when it is produced. This gas is then electrically charged at precise intervals when the Plasma TV is turned on. The electrically charged gas then moves through the red, green, and blue phosphors (A phosphor is any material that, when exposed to radiation, emits visible light ), creating a television Picture. These phosphor cells ( red, green, and blue phosphors) are called pixels.
Although Plasma television technology eliminate the need for the bulky picture tube and electron beam scanning of traditional televisions, because it still employs the burning of phosphors to generate an image, Plasma televisions still suffer from some of the drawbacks of traditional televisions, such as heat generation and screen-burn of static images.
How a LCD TV Works
LCD TVs use a different technology.
LCD panels are made of two sheets of clear material, are then polarized, and glued together. One of the layers is coated with a specific chemical compound that contains the separate liquid crystals. An Electrical charge is then passed through the crystals, allowing the crystals to either let light through or block the light and this creates your image.
LCD crystals do not produce light on their own , so a light source, much like florescent bulb is needed for the LCD to produce a visible picture.
Different from the old style TV or a Plasma TV, there are no phosphors that have to be energized, less power is needed and less heat is generated than a Plasma or old style CRT television. Also, there is no radiation emitted from the LCD screen.
Plasma vs LCD
Plasma over LCD ADVANTAGES:
1. The availability of Larger screens.
2. Deeper blacks for a Better contrast ratio.
3. Clearer color and saturation of the colors.
4. Good motion tracking, very little or no motion lag especially with the faster moving images.
The DISADVANTAGES of Plasma vs LCD are:
1. Plasma TVs are more sensitive to the burn-in effect of static images. It is similar to when you stare at a bright light and then close your eyes and you can still see the light. It goes away but it can be a pain in the butt.
2. Plasma TVs create more heat than LCDs, because of the light needed for the phosphors to create the images.
3. Does not work as well at high altitudes.
4. Shorter screen life span (about 30,000 hours which equals 8 hrs of viewing a day for 9 years). The good news is, screen life span is improving to as high as 60,000 hours because of improvements.
LCD ADVANTAGES over Plasma are:
1. No burn-in effect of static images.
2. Uses less power so it operates at a Cooler temperature.
3. No problems at higher altitudes use.
4. There is an increased image brightness.
5. Longer screen life (about 60,000 hours – Most likely all you will need to do is replace the light source, not the whole thing).
6. Weights less than a Plasma TV so it is easier to mount on a wall.
DISADVANTAGES of LCD vs Plasma televisions include:
1. Less of a contrast, you don’t get the deep blacks of a Plasma for that crisp clear picture.
2. Doesn’t track motion well (fast moving objects may be a little jittery) – But, this is getting better with the new design of the 120Hz screen refresh rates in top-end LCDs.
3. Hard to find the larger screen sizes. But they are starting to show up on the market at the higher prices.
4. LCD TVs usually cost more than same-sized Plasma TV, However the price of the LCD is coming down due to increased production.

Peter Thomas asked:
In this busy day and age, spending what free time you have needs to be as enjoyable and relaxing an experience as possible. Nowhere is this more relevant than with your TV, whether it’s for watching a DVD, or using it to play the latest games on your Xbox 360 or PlayStation 3 on. With the features on the latest models, choosing a Hitachi plasma TV can offer the solution that you’ve been looking for.
With Hitachi’s new Platara range of plasma TV’s, picture and sound quality has never been better. Even with the largest 42″ model, Hitachi has managed to maintain a depth of only 90mm deep, so it won’t take up any major space in your living room, whether you let it sit freely or decide to wall-mount it. Despite the relative slimness of the model, it’s still fully laden with features.
Using Hitachi’s patented ALIS technology, which offers bright yet bold pictures displayed in high resolution, their flagship 42″ model, the 42PD9700 contains a wealth of features, including:
· Picture Master HD Technology, for the sharpest pictures yet
· Integrated Digital TV (IDTV), offering digital transmissions from the box, without the need for a separate cable or satellite connection
· High Definition ready, offering future proof upgrading
· Motorized swivel stand
However, if this model appears feature packed, then the new Hitachi Ultravision Plasma HDTV range is the nest level up in plasma TV’s. With patented technology, these models offer the ultimate in plasma picture quality. Incorporating the world’s first true HD display of 1080i, the 42HDX99 also impresses with:
· Picture Master HD III Video processor, which scans every single frame of movement to provide a crystal sharp image
· Day & Night Picture Memory, allowing easy switching between preferred screen settings
· Film Quality Image Tuning, which improves the detail in both highlight and shadow
· Natural Color Deep Black Anti-Reflective Glass Screen, which reduces the effect of sunlight on the screen and allows far superior pictures
· Digital Color Management III, which automatically re-tunes its settings when attached to a digital camera to match that objects color display
However, even this phenomenal set is outshone by its bigger brother, the 55HDX99 Ultravision Director’s Series. With all the features of the 42″ model and more, this truly is the pinnacle of plasma TV’s and will enhance anyone’s living area beyond compare. With intelligent remote controls that allows you to tune your whole home cinema system to your TV remote, and an HDMI interface for connecting superior products such as HD DVD players, this really is the next generation of not just Hitachi’s plasma TV’s, but any of its competitors as well.

Victor C. Reagan asked:
Samsung is one of the leading brands of high definition televisions, whether it’s LCD or Plasma HDTVs. Samsung even makes good rear-projection HDTVs. If you’re thinking about replacing your old television with a great HDTV, then, it is a good idea to consider a Samsung HDTV, like one of these top Samsung HDTV models.
Samsung UN55B8000
This LED-lit Samsung HDTV is one of the latest offered by Samsung, as well as one of the slimmest. Indeed, the UN55B8000 is razor-thin at 1.2 inches, although its picture quality is more eye-catching, with popping colors and blacks that are amazingly pure for an LCD television. Unlike many LCD TVs, it offers fluid frame transition, as well, because of its Auto Motion Plus 240Hz technology. It also carries a bunch of cool features, such as a sidebar for internet widgets, DLNA connectivity and an extensive Content Library while offering four HDMI inputs and a USB interface for you to share your digital pictures and videos with ease.
Samsung UN46B7000
Like the UN55B8000, the Samsung UN46B7000 has an LED backlight, which contributes to the fact that it is light, cool and extremely energy-efficient. It also has accurate colors and deep black levels, while its dejudder processing and 120Hz refresh rate combine to create sharp and clear pictures all throughout, even during fast motion sequences. In terms of connectivity, it offers four HDMI inputs, a PC input so you can use the screen as a computer monitor, two USB slots for sharing your photos and an ethernet port to connect to your network.
Samsung LN46A950
The Samsung LN46A950 is also a good choice for an LCD HDTV. With its LED backlight, it reproduces black levels that are amazingly deep for an LCD television, as well as extremely accurate colors. Other features include solid video processing, a lot of pre-loaded interactive content, four HDMI inputs, a PC input and an ethernet connection to stream photos and videos from your network. It also has a lot of picture controls, which allows you to calibrate the picture quality of this HDTV to perfection.
Samsung LN52B750
The LN52B750 may lack an S-video input and more importantly, an LED backlight but it still is a great choice for an LCD HDTV. In fact, its black levels are impressively deep for an LCD TV. Its motion sequences are clear, too, due to its very good dejudder processing. Like other Samsung HDTVs, it offers built-in content and Yahoo widgets, and still provides solid connectivity with four HDMI inputs and a PC input.
Samsung PN50B850
If you would rather own a Plasma HDTV, this Samsung HDTV is a great choice, with many innovative features of its own. It has a FilterBright panel to minimize glare and reflections, a Real Movie Mode for playing 24p signals and a 600Hz Subfield Motion drive for clear fast-moving scenes. The best thing about the PN50B850, though, is that it is Wi-Fi ready. All you have to do is buy the Samsung Linstick and you’re all set to receive wireless signals. You can also wire it to your network via an ethernet connection or connect your computer to its PC input. It also offers four HDMI inputs and two USB slots.
Samsung PN50A760
This Samsung HDTV is also a good choice for a Plasma HDTV. Like the PN50B850, it also has a FilterBright panel to reduce distractions, as well as DLNA connectivity for network streaming. It has its own great features, though, such as advanced contour distortion reduction, which delivers sharp images on curvy surfaces even during fast moving scenes; day and night settings for optimal picture quality all the time, and InfoLink feature, which allows you to access the latest news, weather and other important information with the push of a button.
Samsung HL61A750
Finally, if you would rather get a rear-projection HDTV, you might want to keep an eye out for this Samsung HDTV, which delivers outstandingly accurate color temperatures and infinite black levels for superior picture quality. It has a good range of connectivity options, too, such as three HDMI inputs and a PC input, although it lacks a USB interface, an ethernet port or an SD card slot. It is comparatively inexpensive, too.
