Modern Trends And Uses Of Screensavers And Wallpapers

n

Both screensavers and wallpapers, whether for a PC or smart phone, are mainly used to decorate your device and enable you to make your personal computer or phone look unique and different from others. A screensaver is a computer program that makes the screen blank or fills it with different moving patterns or images when the computer is not being used. In the beginning, a screensaver was designed to check phosphor burn-in on plasma computer monitors or Cathode Ray Tube. This is the reason behind its name. Now, screensavers are mainly used for security, entertainment or to display information about the system.

Original use of screensavers

Before the initiation of LCD or Liquid Crystal Display screens, most of the computer screens were driven by cathode ray tubes (CRTs). Such screens have a phosphor coating on their insides.  If the same image is displayed on the CRT screen for a long period of time, the properties of open areas of the same phosphor coating eventually and permanently change. This leads to a darkened shadow image on the screen and is referred to as a ‘screen burn-in’. All devices which use CRTs are vulnerable to this screen burn-in. Programs were then designed to avoid these effects. Such programs automatically changed the images on the screen when the computer is not in use.

Modern utility of screensavers

In the modern age, when CRT screens have gone out of fashion, the original use of screensavers has lost its meaning. Rather, they are mainly used as a decorative background or for other purposes. Screensavers are also used as password protection. One can configure the settings in such a way that once the screensaver is activated, nobody can access the computer. Screensavers are also used to scan the hard drives for any viruses. There are certain screensavers that offer the news headlines and are educational. They are entertaining too as they can enhance the decorations and festivities during holidays. Sometimes, a purely black screensaver may be your best option to save power.
