Human tracking in front of a LED display

Hi all,
I am wondering if the projector can be replaced by a LED monitor.
Will the IR cameras that so gracefully track moving objects in front of a projection surface, will still track those objects in front of the LED screen?

That is, is the projected content equally invisible to the IR camera whether a projector or a large led screen is used?

thank you

yes IR camera won’t record light in visible spectrum
