Is there a command line that can turn off the screen but operate it?

Scrcpy has the command "scrcpy - sw", but you have to open a window, which cannot be operated in pure command line mode.
Can Linux have command line for screen operation? thank you!

Hi. It is hard to understand what do you want.
Ws-scrcpy should have similar feature to -S/--turn-screen-off flag of the original scrcpy. There is a button and a checkbox under More menu (three dots).
See #69

I mean that I want to control the switch of the screen through a terminal or a sh file, so that I can control multiple mobile phones at one time or automate the process. I don't want to click on the page one by one.

is there any solution for this? I want to run ws-scrcpy with the screen off
