Always on display的意思

"Always on display" (AOD) is a feature found on some smartphones and smartwatches that allows the device's screen to remain partially lit or active at all times, even when the device is not being actively used. This means that users can check the time, date, or other important notifications without having to press any buttons or wake the device up.

The AOD feature is typically customizable, allowing users to choose what information is displayed and how long the screen remains on before dimming or turning off completely to save battery life. Some devices may also offer different AOD modes or styles, such as a monochrome or low-power display mode to conserve battery life.

The Always on display feature is particularly useful for people who want quick access to important information without having to interact with their device, or for those who frequently check their device for notifications. However, it's worth noting that having the screen on at all times can drain the device's battery more quickly, so users may need to balance the convenience of AOD with the need to conserve battery life.
