With current screens, not much, but with older CRT (television-like screens) a constant image did a sort of "burn" into the screen, if they were left on long enough, so you'd see the words (or whatever) all the time. A screen saver moved the image around so nothing had a chance to really "burn in", and thus "saved the screen".
You can still sometimes see this on ATMs that don't have screen savers - they have login information permanently displayed.

On original crt monitors the screen would eventually burn the layout of a page in if it was left on that page regularly. The idea was to make the screen do something different if the machine was unused for a while. I know one case where a similar problem was encountered in another way. A CCTV system using crt monitors (at a prison) had been running for about 18 months. A new external patrol system was set up, and a guard came back from patrol and saw a van parked near the wall which he had not seen on patrol. He went back to check and it wasn't there. It turned out to be a van which parked there every night, and it was still visible in the daytime. The cure for this was to make the cameras move a small amount at intervals.

With old CRT monitors (most use LCD now) it would burn an image into the glass if you left it there too long. This still happens somtimes with LCD called Image Persistance. With a screen saver this is less likely to be a problem.

Screen Saver ??
It just saves our monitor screen from getting damage and also for some security purposes too...

it stops the pics or visual from burning into your screen, and the moron that said with lcds it does not matter, he/she is not nery bright, LCDS are the worst for having the backgrounds burning into the screen if left idle and sitting there for any period of time, the screen saver keeeps all the dots per inch from sticking and staying in 1 spot, that does not mean you need a very authentic screensaver for that will slow your computer down drasticallly! good luck and do use one or eventually you will see 1st hand what i'm talking about!

A software program that displays constantly changing images or dims the brightness of a display screen to protect the screen from having an image etched onto its surface.

technically as the name implies " SCREEN SAVER" in the old days it is use to save your screen by means of dimming and reducing the output hertz of the monitor...to minimize the burnt color or discoloration.... but now a days....i think i doesnt matter...but still i use them...
hope this help you.

Well it used to help prevent images from burning into your computer's screen but nowadays it's more or less just a customizable feature.

I use it to display my photos or look cool.
Otherwise I set my system to go into power save mode and blank the screen to save energy.
