Always-on display

An always-on display (AOD) is a smartphone feature that has the device continue to show limited information while the phone is asleep. It is widely available on Android handsets, and is available on Apple iPhones since the iPhone 14 Pro. On some Android devices, the feature is sometimes called Ambient Display (Google Pixel) or Active Display, depending on its implementation and behavior. Depending on the phone's design, it may be a replacement or complementary to another feature, such as the notification LED.
