screensaver

1. (software) A computer program that displays aesthetic patterns or images when the computer is not being used, originally intended to prevent screenburn.Examples: "I configured my screensaver to appear after only two minutes, because I enjoyed watching it so much."

2. (proscribed) The background picture of a computer, smartphone, or similar mobile device.Examples: "But she changed her screensaver, which was a photo of Julian eating scrambled eggs—he was smiling, holding his fork away from himself, as if he were waving the eggs at her—and replaced it with a photo of Olivia, looking up from her desk […]"; "If he wanted praise, or sympathy, or the chance to talk over a sensitive subject, he turned to me. A friend told me that she sat down at her computer one day to discover that her husband had changed her screensaver to read: “Be nice to Lloyd."; "You can tell a lot about a person by the desk they keep. Her real name was Mary Stachowicz but we decided to call her Jenny Talia. It's funnier for us. She uses bulldog clips, which I think is a bit lesbiany, but I guess it's right for the character. Her screensaver is a picture of Cher, not the actual Cher, but her mother in fancy dress."proscribed
