Auto Pixel Shift - Prevent Image Screen Burn In
An ongoing problem with both Plasma Displays and Conventional TVs is image burn in. This occurs when a single image is displayed continuously on the screen over a long period of time. The result is burn in of the image into the screen itself, thus degrading viewing. SAMSUNGs Plasma Panels incorporate auto pixel shift technology. The picture automatically shifts by 1 pixel in all directions every second, non visible to the naked eye, thus preventing burn in.
Is this a gimmick, or does it work? Why don't other makes implement it?
