Image burn-in occurs on CRTs and plasma panels when the same picture is displayed for long periods. This causes the phosphors to overheat, losing some of their luminosity and producing a "shadow" image that is visible with the power off. Burn-in is especially a problem on plasma panels because they run hotter than CRTs. Early plasma televisions were plagued by burn-in, making it impossible to use video games or anything else that displayed static images.

Plasma displays also exhibit another image retention issue which is sometimes confused with [[screen burn-in]] damage. In this mode, when a group of pixels are run at high brightness (when displaying white, for example) for an extended period, a charge build-up in the [[pixel]] structure occurs and a ghost image can be seen. However, unlike burn-in, this charge build-up is transient and self-corrects after the image condition that caused the effect has been removed and a long enough period has passed (with the display either off or on).

Plasma manufacturers have tried various ways of reducing burn-in such as using gray pillarboxes, pixel orbiters and image washing routines. Recent models have a pixel orbiter that moves the entire picture slower than is noticeable to the human eye, which reduces the effect of burn-in but does not prevent it.<ref>{{cite web|url=http://www.thebestplasmatv.com/guides/features/|title=Pixel Orbiter|access-date=2010-10-25|archive-url=https://web.archive.org/web/20120718085218/http://www.thebestplasmatv.com/guides/features/|archive-date=2012-07-18|url-status=usurped}}</ref> None to date have eliminated the problem and all plasma manufacturers continue to exclude burn-in from their warranties.<ref name=PDP3/><ref name=PDPburin>PlasmaTVBuyingGuide.com – [http://www.plasmatvbuyingguide.com/plasmatv/plasmatv-burnin.html Plasma TV Screen Burn-In: Is It Still a Problem?] {{Webarchive|url=https://web.archive.org/web/20190516162927/http://www.plasmatvbuyingguide.com/plasmatv/plasmatv-burnin.html |date=2019-05-16 }}</ref>
