Plasma HDTV - What About Burn-In?

If you are already a HDTV research, you heard about a nasty little problem that only for plasma and CRT series, known as burn-in. This means that if you have $ 4000 plasma screen is imprinted with the spectral image of a logo or a television channel the contour of a mailbox, because certain parts of the screen are aged faster than others. But it seems a big problem, because people keep buying expensive plasma HDTV? Burn-in is really worth worrying about?

Burn-in Sensitivity in Modern Plasma HDTV

The HDTV is very competitive these days, manufacturers and the plasma are really starting to feel the competition from the LCD industry. So you can bet they are doing everything possible to burn-in. Screen technology has become the point where the use of the TV (which begin with a detailed breakdown in the works) will not cause a problem, but ill just may. And many of the new plasma HDTV, the Samsung HPT5064 have a "protective screen burn in" on TV-light to repair the damage.

Image retention against burn-in

Image Data retention is an effect that we have seen, could, after switching from a CRT TV in the night: the last image displayed on the screen stays there for a while 'time after the TV is off, then slowly fades . This is caused by an accumulation in phosphorus (the image of light elements on the screen), and will follow the show was shut down for a little while.

Burn-in, on the other hand, is permanent. As is irregular maturation of the screen phosphors, the "burning" the image will always be there, like a tattoo. It may be a lot of time in one stuff 4:3 (not widescreen) aspect ratio, only a news channel with a firm "news ticker", or a game with a stationary screen elements. Just like a tattoo can be removed with little difficulty, there are ways to fix a burned screen. But one ounces prevention is worth a pound of cure: a pause of the procedure, if the sentence is new.

The Break-In Procedure

If you prefer to be sorry, you must go through a break in the process, if the TV is new. In 2004, Panasonic has a detailed knowledge of the problems and provided with some guidelines for the new plasma-owner:

In the first hundred hours:

* Make sure the display mode of display (aspect ratio), which fills the screen (there are often three or more options to choose from). The jury is in this state, in what is the "right" mode.
* Turn the contrast to 50% or less.
* In short, the 4:3 mode to confirm that the side bars are gray until the middle of the risk of burn-in.
* It is based on a "full screen" (Just, Zoom, Full) during the first hundred hours of use.
* During the first hundred hours of use, the same channel for longer periods. This should prevent other channel logos and images to be maintained.
* Avoid static images (video games, pictures, DVD screens, etc.), while the hundreds of hours of break-in.

After hundreds of hours during the break, during the next nine hundred hours:

* Continue to set the contrast to 50% or less.
* Limiting the use of 4:3 mode to 15% of observation time.
* Limiting the use of static images (computer, video games, etc.) to less than 10% of the time ads.
* After the show a thousand hours, the plates are much less likely to experience image burn-in.

The Bottom Line

HDTV experts agree that now burn-in is an overstated problem. Complaints hours are from a much lower percentage of property than before. Buying a plasma HDTV in late model, with a pause of the procedure, and to prevent the display of certain habits should be a possibility of damage to almost zero.
