On computers, a wallpaper or background (also known as a desktop wallpaper, desktop background, desktop picture, or desktop image) is a digital image (photo, drawing, etc.) that serves as a decorative background for a graphical user interface on the screen of a computer, smartphone, or other electronic device. Wallpapers are often used on the desktop of a computer, but they also serve as the background for the home screen of a mobile phone. Despite the fact that most devices come with a default background image, current gadgets frequently allow users to alter it manually.
Before Windows XP, the word “wallpaper” was used in Microsoft Windows (where it was referred to as “desktop background”), but macOS refers to it as “desktop picture.” The phrase “desktop pattern” was used on earlier systems that permitted tiny repetitive patterns to be set as backdrop graphics.
Animated backgrounds (also known as live backgrounds or dynamic backgrounds) are wallpapers that use a moving picture or a 2D / 3D scene as the operating system background rather than a static picture. It can also refer to wallpapers that are cycled through a playlist, frequently with transition effects. Animated wallpapers are supported natively by some operating systems, such as the Android operating system.
Pictures from a folder can be cycled through at regular intervals on modern Windows PCs. Although Windows does not allow animated backgrounds by default, third-party software may be installed to enable the use of animated photos, video files, 2D or 3D scenarios, and web pages as wallpapers. The Active Desktop feature in Windows 98 and subsequent versions provided similar features.
In 2.0 (Eclair), live wallpapers were included to enable native support for animated wallpapers. Live wallpapers are software applications that offer a changing backdrop picture and may allow for user interaction or utilise other hardware and software components within the device from a technological standpoint (accelerometer, GPS, network access, etc.).
