Sharing MBP screen

MBP screen crashed when it was closed with a pencil left on the keyboard. Now only horizontal and vertical lines where the pencil compressed the screen, but not the entire screen. My question to all of you fine folks is; Is to steal the MBP screen using my iPhone? I was thinking I could have the MBP screen displayed either on my iPhone or on my wife’s iPad screen . . . Less the punctured screen.

HELP PLEASE ! ! !

P.S. None of these 🍎’s are very new.
