Prevent phone screen from turning on with alarm screen when alarm starts with just alarm sound only

Often times, the screen turning on wakes me up before the gentle volume increase reaches full volume, and I find it unpleasant, even with phone at lowest brightness. So I would like an option for only the alarm sound to play with no screen turning on.

hello! add please function for AMOLED screens which will start alarm without turn screen on.

I like to listen radio instead of short ring and screen is always on for 30 minutes…
