What is the Difference between Plasma TV and LED TV?
Today the leading television technology has revolutionized the market of flat-panel TVs by successfully replacing tubes as the direct-view televisions of choice of millions. Now you can enjoy the latest flat screen technology by hanging flat sets on the wall or on the ceiling or right above the mantle instead of a trophy buck. The two major players in this field are plasma and LED. So, we will try to identify the difference between a Plasma TV and an LED TV.
Working
Plasma: In a plasma display, there are millions of individual pixel cells which allows electric pulses (produced by electrodes) to excite rare natural gases like Xenon and Neon. Once fully excited, these gases glow and produce light. This light then illuminates a proper balance of red, green, and blue phosphors contained in each pixel cell to produce the correct intensity of light and display a proper color sequence from the light. If you take a closer view of a Plasma TV you can actually see the individual pixel cell coloration of red, green, and blue bars each separated by black ribs.
LED: In a LED display, hundreds of tiny LEDs (Light Emitting Diodes) are responsible for illuminating the LCD pixels to produce back light for the LCD panel. The LEDs are equally distributed around the back of the television’s panel or are placed at the edges of the screen to create a very thin display chassis. Basically, LED backlit TVs are the newest creation in LCD TV technology which contains an LCD display element (front panel). LED TVs are predominantly available in two types one based on conventional rear (back) and the other on the latest edge lighting. LEDs has become stroke of luck for all LCD TV manufacturers cause it gave them strength and confidence to compete with the picture quality of plasma TV.
Picture Quality
Contrast or Black Levels: Though plasma technology has achieved quite higher contrast ratios still they apply maximum power to produce full white or lighter image. As opposite to plasmas, due to the new LED back lighting there have been tremendous improvements in black levels and contrast. Advantage: Plasmas.
Color Accuracy: Plasma TVs due to their richness in color information and more natural coloration are best suited for the rooms with lower to normal lighting. However, LED TVs have closed this gap through manipulation of the new back lighting system. Surprisingly colors are more vibrant on an LED TV and more subdued n plasma. Advantage: Both.
Viewing Angles: Off-angle viewing of plasma is excellent from all angles as each individual pixel being lit however the image starts fading slightly when seen from extreme angles from sides or from above or below (i.e. off-axis). Usually it occurs after around 45 degrees off center. Advantage: Plasmas.
Functional Concerns
Computer Use: LED TVs response time has increased up to 120Hz and 240Hz refresh rates which in itself are dramatic improvements in this area whereas plasma technology still has to improve on screen burn-in as well as computer and static signal handling related issues. Advantage: Both.
Fast-Moving Video Playback: Plasma can easily display refresh and handle rapid movements in video as per the standard most viewers expect. Many new LED TVs have 120/ 240 refresh rates which has reduced motion related blur to some extent. Advantage: Plasmas.
Screen “Burn-In” or “Ghosting”: Plasma TVs suffer from burn-in produced by static images left on-screen with very bright settings for hours, which produces an after-image ghost if burn-in is prolonged. This burn-in or ghosting thing is temporary and goes away after watching moving images. LED TVs don’t have any image retention concerns due to their LCD screen technology “twisting crystals”. Advantage: LEDs.

Useful Buying Tips on Plasma Television
Plasma television is now acknowledged as a superior quality product with several innovative features. When the cathode ray tube (CRT) models became obsolete, consumers have two options namely LCD and Plasma televisions. Discussions or debates are going on among the consumers about the respective advantages of these two categories of televisions. Market watchers in UK and in the continent have no doubt that the competition between the above two models is a no-holds-barred phenomenon, but many agencies feel that plasma is having an edge over LCD as far as market share is concerned. In a fast changing scenario, there are claims and counter claims about the superiority of each over the other.
The most important factor that attracts the consumer is the affordability of plasma which is considered as cheaper than LCD television. When it comes to large sized screens, plasma, no doubt is the best bet. It is well known for better colour reproduction and contrast ratio. Another positive feature is the wide viewing angle offered by it. Consumers find it suitable for group viewing because of this advantage. The light weight device is available in attractive designs and can be hanged from the wall and is a space saving option. The unique technology offer uniform screen brightness which is a boon to those who have ophthalmic problems while watching television for longer periods. Modern plasma screens are also featured with anti-glare coatings apart from the above mentioned advantage. With extended longevity plasma can survive for more than 20 years and is considered as a productive investment by the consumers.
But there is one irritant factor that plagues the popularity of the plasma since it was introduced for public consumption. The screen burn-in caused by the phosphorus gas created apprehensions in the minds of the consumers about the durability of this product. Having sensed the consumer reactions in this context, manufacturers have announced unequivocally that suitable remedial actions have been taken to eliminate the burn-in problem in plasma television. Apart from improving the quality of phosphorus used, the unique motion logo technology is adopted to prevent burn-in. Progressive scan, closed caption decoder and temperature control are other technological features that make plasma TV a superb product. In the earlier models energy consumption was very high when compared to other categories like LCD. But later technological changes were effected to reduce energy consumption.
Markets have several brands and models of plasma televisions in response to the increasing demands of the public. Panasonic, one of the market leaders have announced their ambitious plan for 2010. They will be introducing 69 different models in a collaborative venture with UK Viera. The company claims that plasma can offer more comfortable viewing experience than LCD. This is based on the findings of a research team from Munich University which was commissioned by them. Samsung 50 inch HD Ready TV is offering novel features like 3D digital filter and 3 HDMI connections. Pioneer Kuro, Hitachi, LG, Fujitsu and NEC are other leading plasma television manufacturers who have offered innovative products in the recent past.
The year 2010 will see innumerable models of Plasma television entering the markets, thanks to the ambitious programmes of the companies. The competitive environment prevailing in the global television market will make the products more affordable than in the past.

How to Choose a Surge Protector for Your HDTV Television
Electrical power surges are the most notorious enemies of all electrical equipments. They can enter your home’s electrical system at literally the speed of light. However, there is a very simple way that you can protect electrical equipments in your home including your HDTV set.

Finding a surge protector for your home theater is a very easy task that is most of the time overlooked. These devices are considerably cheap and can be found almost anywhere especially in stores that sell electrical equipment. You don’t have to spend a fortune on a very expensive product, mostly anyone will do the job.
To find a suitable device to protect your electrical devices you need to be aware of a very important thing. The product has to be able to handle the Watt load of all the devices that you will be connecting to it. To calculate the minimum amount of Watts that you need your surge protector to handle, just make a sum of all the Watts that the equipment you will be plugging consumes per hour. This is a very easy task. Look in the back of your HDTV television where the electrical requirements of the unit are listed and you will see something that looks like: 120 Hz AC 120w . In this case, 120w would be the power consumption of the television set. Do the same with all the devices that you are planning to plug in to the surge protector and add the numbers. This sum will represent the minimum amount of power load that your surge protector needs to be able to handle. Do not buy a unit that cannot handle your system’s load. As the device will turn it self off when it can’t handle the load.
