If you get scratch marks on the screen from touching it, then you're doing it wrong
As Robert22 says, the new touch screens rely on detecting when the user breaks the IR beams projected from the sides of the screen, so you don't even need to actually touch the screen. It's enough to just put your finger close enough to break the beams, but for practical purposes this would mean touching the screen. You don't need to press on it though.
