Plasma HDTV - What about burn-in?

If you have studied high-definition televisions, did you hear about a nasty little problem, only to plasma and CRT devices, known as burn-in. That is, if your $ 4,000 plasma screen with the ghostly image of a TV channel logo, or the shape of a mailbox is stamped, because some parts of the screen have aged faster than the rest. But if there is a big problem, because people always expensive plasma HDTV? Burn-in is really worth?

Burn-in susceptibility in modern plasmaHDTV

HDTV

The HDTV industry is very competitive these days, and plasma manufacturers are really feeling the competition from the LCD industry. So you can bet that they do everything to eliminate burn-in. The screen technology is improving to the point where the proper use of television (from a detailed break-in procedure) is not a problem, but could careless use only. And many of the new plasma HDTVs, like Samsung HPT5064 have a "Burn-Mode "built into the TV to repair minor damage.

Free Burn-In vs. Image Retention

Image retention is a common effect you might see after switching to a CRT TV at night: the last image appears on the screen stays there for a bit 'after the TV is off, then slowly faded. This is caused by a structure responsible for the phosphors (the bright pixels on the screen), and feet, after the display has been off for a while 'with power.

Burn-in, onOn the other hand, is permanent. Since the uneven aging of phosphors of the screen occurs, the image "burned" will last forever, like a tattoo. It can be a lot of time spent in front of the stuff in a 4:3 (not widescreen) are caused, watch a news channel with a firm "news ticker", or a game with the elements of the screen stopped. can only be removed like a tattoo with a little effort, there are ways to fix a burned-screen. But an ounce of prevention is worth a poundCare: Follow a break-in procedure when the set is new.

The break-in

If you'd rather be safe than sorry, you need a break-in when the TV is to go again. In 2004, Panasonic has commissioned a detailed view of the problem and came up with some guidelines for owners of new plasma:

In the first 100 hours:

Make sure that the display is in display mode (aspect ratio) that completely fills the screen (there are often three or more settingsto choose from). The board is supplied in this state, the so-called rules "Solo". Turn the contrast to 50% or less. Short reach the 4:3 mode to confirm that the page set to medium gray bars to minimize the risk of burn-in. Specifies the amount of "full screen" (Just, Zoom, Full) position during the first hundred hours. During the first 100 hours and not watch the same channel for long periods of time. This should prevent channel logos and otherStill images are stored for. Avoid any static images (video games, computer images, DVD title screens, etc.) during 100 hours.

After 100 hours of operation phase, while the next 900 hours:

Continue to keep up with the contrast setting to 50% or less. Limit the use of 4:3 mode to 15% of broadcasting time. Limit the use of static images (computer, video games, etc.) to less than 10% of broadcasting time. After thousands of 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. The complaints now come from a much smaller percentage of the owners before. The purchase of a model of plasma HDTVs in delay, a break-in procedure and the avoidance of specific viewing habits should be zero to reduce the likelihood of damage to almost.
