- SCREEN BURN
- by Editor, NYBUG, June 1987

- (What happens when you leave your computer on)
-
- Q. Sometimes I leave my computer on for hours at a time. Can
- this practice harm the machine?
-
- A. The back of your monitor is coated with phosphors which glow
- when bombarded with a stream of electrons. This bombardment can
- be controlled to create the precise images on your screen, but if
- it is kept on for a long period of time, the phosphors of that
- image will burn out, leaving a permanent "ghost" on your screen.
- There are programs that will turn off your blank after a few
- minutes if a key is not pressed. This will prevent the problem.
