Does Xiaomi Watch S3 support continuous screen display (low light mode/AOD)?

It supports screen-time display. After turning it on, the watch will enter the screen-time display state after the screen is turned off. When the screen is on, you can wake up the screen by raising your wrist or tapping a button to exit the screen.
Setting method:
Go to [Settings] >> [Display and Brightness] >> [Information screen display] >> You can turn on [Smart] or [Scheduled]. The default period for scheduled is 08:00-22:00.
Note:
When the screen display is turned on, the screen will go black if you take your wrist off for 5 minutes, and the screen will go black if sleep is detected at night.
Turning on this feature will reduce the battery life of the watch.
