New facts on Screen burn in
April 28, 2007
What is burn in?
CRT (Cathode Ray Tube) display and Plasma TV use phosphors which are coated on their sub-pixels (red, blue and green). In high bright settings of your TV, or when a stagnant, bright image is left on the screen for a prolonged time, the sub-pixels that produce the image can be worn out, in other words, the phosphors become prematurely aged. This results in the permanent formation of the image, known as the screen burn in. Both CRT and Plasma TV are susceptible to burn in.
Do the latest Plasma TVs suffer screen burn-in?
No, Plasma TVs, made in the last couple of years, adopt two techniques to handle this problem.
The new motion adaptive anti burn in technology makes the ghosting effects undetectable by TV viewer. It is found that the use of green phosphor increases the overall life of phosphors.
Okay, what are the precautions I should take to prevent burn-in
Dont leave still, bright images on your plasma TV for a long time. (even 10 or 15 minutes can be hazardous). If your Plasma TV is a high end one, use proper screen saver settings and power management settings.
The initial 200 hours period of brand new Plasma TV is crucial. The phosphors burn intensely resulting in easy burn in. This often happens when the bright-contrast settings are at maximum levels or a bright image is left on the screen for a long time. It is a good idea to reduce bright and contrast settings to half of the original settings (100 %), a step that will ensure the long life of your plasma TV.
Make sure you watch all the programs in full screen format (16:9) as this will prevent black bars that appear on your TV screen.
Latest high end Plasmas are more resistant to burn in and spending a little time over the plasma TV reviews available in our site may often prove helpful in this regard.
Plasma TV Specifications – The Basics

Plasma TV Specifications
So you have decided to buy a Plasma TV. Well, it is easy enough to just flip over pages of catalogs, surf the Internet, or go to your nearest appliance showroom to check out the latest models. But with the market practically flooded with the latest brand, model, and features pretty soon one will be overwhelmed with the options available. This can be avoided if at the onset, one knows what to look out for in buying a Plasma TV. And the best way to start is by knowing the basic specifications of a Plasma TV.
The Basic Specs
Plasma TVs are different from our old TVs in the sense that they work more like monitors: it requires a TV tuner to show broadcasting signals. Unlike CRT (cathode ray tube) TVs, a Plasma TV has a higher resolution. Those with at least 852 x 480 resolution are called EDTVs (enhanced definition TVs), while those with an impressive 1365 x 768 resolution are classified as HDTVs (high definition TVs).
Flat Screen Advantage
The beauty of flat screen TVs is that it allows one to view what is being displayed practically from any point in the room. This is due largely to the fact that large screens have 160° angle, the absence of curved surface prevents image distortion and glare that are typical of standard or traditional TVs.
Uniform Brightness
From whatever direction you view, a Plasma TV exudes nothing but smooth and uniform brightness. Since it is composed of cells that light up individually, the image displayed is very bright and is visually good from any angle. This is in contrast to “hot spots or irregular screen brightness that are common in some rear and front project TVs.
Absence of Scan Lines
Another positive result of those individually lit cells is that it evenly lights up image being projected because flat TVs have pixels as color-generators. This feature is absent in traditional TVs that make use of an electronic beam to hit the picture tube from top to bottom, thereby causing scan lines.
Vulnerability To Magnetic Material
Cathode Ray Tube (CRT) TVs have electron beams that cannot withstand close proximity to magnetic materials. For example, displayed images are distorted when placed beside stereo loudspeakers. In contrast, Plasma displays do not suffer image deformation in such cases because they have not electron beams. This adds to our viewing pleasure because if one wants to set-up a home theatre system, loudspeakers can be placed just about anywhere near a Plasma TV.
Multi-media Compatibility
A Plasma TVs capability to receive videos of any format makes it one of the most versatile monitors around. Primarily, it is a TV monitor capable of taking in regular TV, videos, as well as High Definition TV (HDTV) signals. It can also be utilized for commercial or business purposes, as it can serve as a computer monitor owing to its capability to accept VGA and SVGA signals from computers. Hence, it is not surprising to know that a typical Plasma TV has inputs for composite video, S-Video and component video, and more than one RGB inputs for computer connectivity.
