A wallpaper or background (also known as a desktop background, desktop picture or desktop image on computers) is a digital image (photo, drawing etc.) used as a decorative background of a graphical user interface on the screen of a computer, smartphone or other electronic device. On a computer, wallpapers are generally used on the desktop, while on a mobile phone they serve as the background for the home screen. Though most devices include a default background image, modern devices usually allow users to manually change the background image.

The term "wallpaper" was used in Microsoft Windows before Windows XP (In Windows XP and later, it is called the "desktop background"). Meanwhile, macOS refers to it as "desktop picture". On older systems that allowed small repeated patterns to be set as background images, the term desktop pattern was used.

History

The X Window System was one of the earliest systems to include support for an arbitrary image as wallpaper via the xsetroot program, which at least as early as the X10R3 release in 1985 could tile the screen with any solid color or any binary-image X BitMap file. In 1989, a free software program called xgifroot was released that allowed an arbitrary color GIF image to be used as wallpaper, and in the same year the free xloadimage program was released which could display a variety of image formats (including color images in Sun Rasterfile format) as the desktop background. Subsequently, a number of programs were released that added wallpaper support for additional image formats and other features, such as the xpmroot program (released in 1993 as part of fvwm) and the xv software (released in 1994).

The original Macintosh operating system only allowed a selection of 8×8-pixel binary-image tiled patterns; the ability to use small color patterns was added in System 5 in 1987. [1] Mac OS 8 in 1997 was the first Macintosh version to include built-in support for using arbitrary images as desktop pictures, rather than small repeating patterns. [2]

Windows 3.0 in 1990 was the first version of Microsoft Windows to feature support for wallpaper customization, and used the term "wallpaper" for this feature. [3] Although Windows 3.0 only came with 7 small patterns (2 black-and-white and 5 16-color), the user could supply other images in the BMP file format with up to 8-bit color (although the system was theoretically capable of handling 24-bit color images, it did so by dithering them to an 8-bit palette) [4] to provide similar wallpaper features otherwise lacking in those systems. A wallpaper feature was added in a beta release of OS/2 2.0 in 1991. [5]

Due to the widespread use of personal computers, some wallpapers have become immensely recognizable and gained iconic cultural status. Bliss , the default wallpaper of Windows XP, has become the most viewed photograph of the 2000s. [6]

Animated backgrounds (sometimes referred to as live backgrounds or dynamic backgrounds) refers to wallpapers which feature a moving image or a 2D / 3D scene as an operating system background rather than a static image, it may also refer to wallpapers being cycled in a playlist, often with certain transition effects. Some operating systems, such as Android, provide native support for animated wallpapers.

Microsoft Windows

Android

Live wallpapers have been introduced in Android 2.0 Eclair to provide native support for animated wallpapers. From a technical point of view, live wallpapers are software applications that provide a moving background image and may allow for user interaction or utilize other hardware and software features within the device (accelerometer, GPS, network access, etc.). [7]

macOS and iOS

macOS has built-in support, via the Desktop & Screen Saver panel in its System Preferences/Settings, for cycling through a folder collection of images on a timed interval or when logging in or waking from sleep. Since macOS Mojave, the user can also select a "Dynamic Desktop" that automatically updates to visually match the time of the day. [8]

Additionally, macOS has the native ability to run a screen saver on the desktop; in this configuration, the screen saver appears beneath the desktop icons in place of the system wallpaper. However, macOS does not feature a built-in interface to do this; it must be done through Terminal commands or various third-party applications. [9]

Dynamically animated backgrounds have also been introduced in iOS 7 and later versions, however they are restricted to the ones provided by Apple. Jailbroken iOS devices can download other dynamic backgrounds.

Linux distros

Linux distributions usually provides their own original backgrounds. For example:

The history of the graphical user interface, understood as the use of graphic icons and a pointing device to control a computer, covers a five-decade span of incremental refinements, built on some constant core principles.

<span class="mw-page-title-main">Screensaver</span> Computer program that blanks the screen or fills it with moving images

A screensaver is a computer program that blanks the display screen or fills it with moving images or patterns when the computer has been idle for a designated time. The original purpose of screensavers was to prevent phosphor burn-in on CRT or plasma computer monitors. Though most modern monitors are not susceptible to this issue, screensaver programs are still used for other purposes. Screensavers are often set up to offer a basic layer of security by requiring a password to re-access the device. Some screensaver programs also use otherwise-idle computer resources to do useful work, such as processing for volunteer computing projects.

In computing, an icon is a pictogram or ideogram displayed on a computer screen in order to help the user navigate a computer system. The icon itself is a quickly comprehensible symbol of a software tool, function, or a data file, accessible on the system and is more like a traffic sign than a detailed illustration of the actual entity it represents. It can serve as an electronic hyperlink or file shortcut to access the program or data. The user can activate an icon using a mouse, pointer, finger, or voice commands. Their placement on the screen, also in relation to other icons, may provide further information to the user about their usage. In activating an icon, the user can move directly into and out of the identified function without knowing anything further about the location or requirements of the file or code.

Active Desktop was a feature of Microsoft Internet Explorer 4.0's optional Windows Desktop Update that allowed users to add HTML content to the desktop, along with some other features. This function was intended to be installed on the then-current Windows 95 operating system.

Its status on XP 64-bit edition and on both 32-bit and 64-bit versions of Windows Server 2003 is not widely known. This corresponded to version Internet Explorer 4.0 to 6.x, but not Internet Explorer 7.
