An issue widely discussed but rarely understood fully is that of "screen burn" Affecting plasma & CRT televisions (both phosphor-based electronic displays) the prolonged showing of a static/unchanged image can leave a ghost-like mark of that picture. The reason for this is that the elements within the tv that emit light (phosphor compounds) lose their luminance with age. The problems don't end there as another more noticeable effect of this technology is that the image quality will eventually (gradually) begin to decline, which results in a "fuzzy" or "muddy" picture.
Various techniques have been trialled to eliminate the above issue but none have so far been entirely successful.
In order to avoid the issue of "screen burn" you have to be careful not to leave any static pictures on your plasma television, this means not pausing your dvd or your sky+HD box for prolonged periods of time. In addition to this, if you are using your plasma with a gaming console or a pc, then do not leave the console on a static menu screen or paused for extended periods. If you are working with a pc then ensure a screen saver is activated after a couple of minutes of inactivity.
An issue not to be confused with the above issue is when a group of pixels are set to display a high brightness for an extended period, due to the build up of charge – another "ghost-like" image is displayed. This effect is temporary and corrects itself when the image that caused the effect has been removed for a sufficient length of time.

This plasma display has a huge number of features that makes it one of the most enviable televisions in its market in 2010.
