FYI there have only been 2 posts to the Master thread I see since 2007.
Here's something interesting.
per xrox in the Master Burn-in thread
"Samsung has done some research on Plasma image ghosting in order to find the true cause. They have found the following:
Image Retention: Caused by residual wall charge left in a cell after discharge. The residual charge increases the discharge probability of the cell and reduces the discharge delay time resulting in a brighter luminance than normal. Image retention can be removed by short periods of white wash or normal program viewing. In other words it is easily removed.
Image Sticking: Caused by excessive sputtering of MgO onto the phosphor material and cell wall during excessive sustained discharge. It is usually characterized as having a slightly brighter ghost image on a dark screen and a slightly darker ghost image on a bright screen. This is a semi-permanent phenomenon. However, it has been found that a white wash of 100hours can completely resolve the image stick.
Burn-In As we all know is uneven-phosphor aging and is permanent. It is also the most difficult to achieve and therefore the most unlikely scenario."
Evidently, the term Burn-In has been defined as uneven aging due to the black bars displayed when viewing 4:3 or 2.35:1 programming on a 16:9 display on a CRT or RPTV and now plasma.
Maybe we should start calling Burn_in Image Sticking and confuse the ... out of everybody.
From a victim of Burn-In ... ugh... Image Sticking.
