Why we use Screensavers

The repeated formation of the same images would target the same points on the screen and damage them. Therefore, the objective of the Screensaver was to constantly change images on the screen so that no particular points were constantly under attack. Screen burns often damaged Cathode Ray Tube or CRT monitors, causing distortion, such as blurred images, additional vertical or horizontal lines, and faded patches. In CRT monitors, images are formed by electron beams that focus on the same points on the screen.

The time duration after which a Screensaver gets automatically activated can be defined by the user.
