Prevention/treatment
Image persistence can usually be reversed by allowing the liquid crystals to return to their relaxed state. In other words, turning off an LCD display for hours or days will relax the crystals and eliminate the image retention. For PC monitors, it is also ideal to rotate desktops, and hide away elements on the screen which normally would be displayed perpetually (like the taskbar in Microsoft Windows or the Dock in Mac OS X). The usage of a screensaver that has a constantly changing image can help as well.
Another approach to removing LCD image persistence is to first create a solid white image and display the image as a screensaver covering the entire display area for an extended period of time.

Famous quotes containing the words prevention and/or treatment:
“... if this world were anything near what it should be there would be no more need of a Book Week than there would be a of a Society for the Prevention of Cruelty to Children.”
—Dorothy Parker (1893–1967)
“I will use treatment to help the sick according to my ability and judgment, but never with a view to injury and wrongdoing. Neither will I administer a poison to anybody when asked to do so, nor will I suggest such a course. Similarly, I will not give to a woman a pessary to cause abortion. I will keep pure and holy both my life and my art.”
—Hippocrates (c. 460–c. 370 B.C.)
