Burn-in on a monitor, when severe as in this "please wait" message, is visible even when the monitor is switched off. Screen burn-in, image burn-in, ghost image, or shadow image, is a permanent discoloration of areas on an electronic visual display such as a cathode-ray tube (CRT) in an older computer monitor or television set. It is caused by ...
Image persistence, or image retention, is a phenomenon in LCD and plasma displays where unwanted visual information is shown which corresponds to a previous state of the display. It is the flat-panel equivalent of screen burn-in. Unlike screen burn-in, the effects are usually temporary and often not visible without close inspection.
Before the advent of LCD screens, most computer screens were based on cathode-ray tubes (CRTs). When the same image is displayed on a CRT screen for long periods, the properties of the exposed areas of the phosphor coating on the inside of the screen gradually and permanently change, eventually leading to a darkened shadow or "ghost" image on the screen, called a screen burn-in.

An image is said to be burned or burnt when its original gamut considerably exceeds the target gamut, or when the result of processing considerably exceeds the image's gamut, resulting in clipping. [1] Colloquially, an image is burned when it contains uniform blobs of color, black, or white where there should actually be detail.
A new technique employed by a novel software utility equalizes burn-in by monitoring how the screen is used and creating an inverse burn image. By displaying the inverse burn image, previous burn-in can be equalized. This means that bright and dark patches will not be noticeable and uniform brightness across the whole screen is achieved.
However, if the image is very intense and brief, or if the image is large, or if the eye remains very steady, these small movements cannot keep the image on unadapted parts of the retina. Afterimages can be seen when moving from a bright environment to a dim one, like walking indoors on a bright snowy day.
