Plasma-TV: Screen burn-in
Plasma-tv producers: Hitachi, Panasonic, Pioneer and Samsung give their answers. Will logos, graphics and other images "burn in" and permanently damage a plasma-tv?
Hitachi: Will TV station logos cause a problem with image retention/screen burn?
TV
logos do not move their position on the screen, but will on occasion
between advert breaks will refresh and for small period of time the
screen goes blank. This is no guarantee that image retention may not
occur. On the basis that the average viewer does not watch the same TV
channel everyday all day is enough to note that instances of image
retention for logos are rare. Hitachi has methods to help reduce the
instance of image retention that maybe subject from displaying TV
channel logos.
Panasonic: Is it true that logos, graphics and other images will "burn in" and permanently damage my plasma-tv?
There is a slight risk of image retention on any phosphor based
technology (like CRTs or plasma). Improvements in panel service life to
over 60,000 hours have minimized the risk of uneven aging and image
retention. In addition, screen savers, pixel shifting, and brightness
level adjustments can dramatically reduce any chance of burn-in. The
rule of thumb: if you don't worry about your CRT, you don't have to
worry about a Panasonic plasma.
Pioneer: Image Retention
If
a picture stays frozen on your plasma display for a few minutes, that
image will not leave a permanent mark. With today's plasmas, you don't
have to worry as much about permanent image retention.
That said, plasma televisions are intended for viewing dynamic moving
images such
as high-definition TV and movies. If a static image (such as a computer
menu) remains on the screen for an extended period of time, there may
be some retention of that image. However, image retention can usually
be washed away by running moving video.
Therefore, you can buy a plasma television with confidence, knowing
that you do not have to treat it any differently
than you would a regular television (although you'll be so grateful for
the brilliant image quality that you'll certainly want to).
Samsung: Are Plasma TVs Subject To Screen Burn In?
Yes, plasma TVs are subject
to screen burn in.
If you have a plasma TV,
we recommend that you limit
your viewing of stationary
graphics and images, such
as the dark side-bars on nonexpanded
standard format television
programs, stock market
reports, video game displays,
station logos, web sites,
and computer graphics
and patterns to no more than
5% of the total television
viewing per week.
Displaying stationary images
that exceed the above guidelines
can cause uneven aging of
PDP displays that leave subtle,
but permanent burned-in ghost
images in the PDP picture.
To avoid this, vary the programming
and images you watch, watch mainly
full screen moving images,
and avoid stationary
patterns or dark bars. On
PDP models that offer picture
sizing features, use these
controls to view different
formats as a full screen pictures.
Current model Samsung Plasma
TVs are equipped with a pixel shift function which reduces, but does not
eliminate, the possibility of screen burn in.
