Screensavers were made originally to protect old CRT monitors from a problem called Phosphor burn-in which occurs when static image or text is displayed for long periods of time however they were used later on for other purposes like entertainment and security.

Modern CRT's are less vulnerable to burn-in problems and LCD screens doesn't face this problems at all so screensavers have lost their main goal that they were designed for , another thing is that screensavers consume power as when running computer normally and it causes screen aging.

According to wikipedia :

A typical LCD screen loses about 50% of its brightness during a normal product lifetime, if left on continuously

So the best thing to protect your screen is simply to turn it off when not used or configuring your computer to set the screen into a lower power mode and that could be done from power management in most modern operating systems.

However , sometimes you need a good or useful screen savers to be displayed if you are going to be idle for few minutes...

and here comes Analogy (the reason this article was written) a useful screensaver that displays a nice hybrid format clock into your screen.
