connect iPhone to iTunes with broken display screen

My iPhone has a broken display screen and I can't connect with my iTunes because it says I have to log into my phone. I can't log into my phone because it is not working. I tried pressing the home button and then acting out the motions of entering my password, but nothing is happening. I have my replacement phone and I'm trying to reset my broken phone, but I can''t do that until I log into iTunes. If someone can advise me on what to do, it will be greatly appreciated. Thank you. By the way, I am doing this on a PC computer.
