Modern screensavers can turn off the screen when not in use. In many cases, the use of a screensaver is impractical. Most plasma-type display manufacturers include methods for reducing the rate of burn-in by moving the image slightly, [7] which does not eliminate screen burn but can soften the edges of any ghost image that does develop. [8]
Unlike screen burn-in, the effects are usually temporary and often not visible without close inspection. Plasma displays experiencing severe image persistence can result in screen burn-in instead. Image persistence can occur as easily as having something remain unchanged on the screen in the same location for a duration of even 10 minutes, such ...
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.
A long period of sales decline occurred in the late 1970s because semiconductor memory made CRT displays cheaper than the $2500 USD 512 × 512 PLATO plasma displays. [12] Nevertheless, the plasma displays' relatively large screen size and 1 inch (25.4 mm) thickness made them suitable for high-profile placement in lobbies and stock exchanges.

The FDA has a guide for how long you can safely store food in the freezer, and it’s not as long as you’d think. Most raw and cooked ingredients only stay good for a few months at most.
How many people have been injured by the recalled Stanley mugs? So far, Stanley has received 91 reports worldwide, including 16 in the U.S., of the recalled travel mugs' lids detaching during use ...
Burn-in is when images are physically "burned" into the screen of the CRT; this occurs due to degradation of the phosphors due to prolonged electron bombardment of the phosphors, and happens when a fixed image or logo is left for too long on the screen, causing it to appear as a "ghost" image or, in severe cases, also when the CRT is off.
