3D Screensavers

With the advent of computers and related technologies, there has been a scope for versatility and innovations with a creative frame work. 3 dimensions are one such important tool that has created waves among the tech savvy people. When we talk about 3 d graphics, pictures and so on, there is a very vital aspect in 3d that has gained popularity among computer users in a very short period of time, it is the 3d screensavers.

A 3d screensaver is a type of computer program initially designed to prevent “Phosphor burn-in” on CRT and plasma computer monitors by blanking the screen or filling it with moving images or patterns when the computer is not in use. Contemporary screensavers are used primarily for entertainment or security.

Before the advent of LCD screens, most computer screens were based on cathode ray tubes (CRTs). When the same image is displayed on a CRT screen for long periods of time, the properties of the exposed areas of phosphor coating on the inside of the screen gradually change, eventually leading to a darkened shadow image on the screen. Cathode ray televisions, oscilloscopes and other devices that use CRTs are all susceptible to phosphor burn-in, as are plasma displays to some extent.3d Screen-saver programs were designed to help avoid these effects by automatically changing the images on the screen during periods of user inactivity.

For CRTs used in public, such as ATMs and railway ticketing machines, the risk of burn-in is especially high because a stand-by display is shown whenever the machine is not in use. In these applications, burn-in is prevented by shifting the position of the display contents every few seconds, or by having a number of different images that are changed regularly.

LCD computer monitors, including the display panels used in laptop computers, are not vulnerable to burn-in because the image is not directly produced by phosphors. For these reasons, 3d screensavers today are primarily decorative or for entertainment, and usually feature moving images or patterns and sometimes sound effects.

One increasingly popular application is for 3d screensavers to activate a useful background task, such as a virus scan or a distributed computing .This is expedient because these applications only use resources when the computer would be otherwise idle. Additionally, using a 3d screensaver with a flat panel or LCD screen instead of powering down the screen can actually reduce the lifetime of the display, since the fluorescent backlight remains lit and ages faster than it would if the screen was turned off completely. As fluorescent tubes age they grow progressively dimmer, and they can be expensive or difficult to replace.

Thus the term “screen saver” is ideally used for saving the screen of any monitor. Now-a-days there are many novel ways of designing a 3d screensaver to attract people across the globe. In addition to catering to the global audience, there are various online agencies and companies that support free 3d screensaver download. These screen savers are available at no cost for the user. The 3d screen savers that are available for free has gained a lot of recognition and fame among the users.
