Screensavers and their purpose
Wednesday, August 27th, 2008Many years ago screensavers have been used to prevent the so-called screen-burn-effect- a permanent disfigurement of areas on a CRT display caused by non-moving text or graphics being displayed continuously for long periods of time. To avoid this effect, screen savers have been used to blank the screen or fill it with moving images or patterns when the computer was not in use. Today, screensavers don’t serve their original purpose and are primarily used for entertainment.
In fact, we don’t need screensavers any more. However we are still using them because they are very pleasant for the eye in our coffee breaks. Particularly complex and colourful 3D-screensavers are extremely nice to look at.
