The issue of image retention on Plasma TVs

The perceived problem with plasma, however, is something called "burn-in" or more technically called "image retention." What this means is that if you keep an image "frozen" on the screen too long, a ghost of the image will stay with the display forever. A good example of things that could leave permanent images on the screen could be news or stock tickers staying on the bottom of the screen, or station logos or icons " sometimes called "bugs." In the beginning, this was certainly an issue. Now, several years later, all of the leading manufacturers of plasma TVs " Panasonic, LG, Samsung, Pioneer, and Hitachi " have all taken several steps to greatly reduce or eliminate completely any signs of image retention.

The Plasma Display Coalition (PDC) acknowledges that there were issues in the past, but those detractors of image quality have been addressed and virtually emliminated in PDPs (Plasma Display Panels). The PDC is comprised of four companies: LG, Hitachi, Panasonic, and Pioneer.
