How to retrieve data from a Cracked and shattered screen.

My son decided to knock my phone down a couple months ago and cracked my screen 2 months later my screen quit working and 3 hours later started turning purple and now completely black. I have a password on it. Is there a way to retrieve the files, pictures and data off it? My SD card apparently didn't save everything and there stuff on my internal memory. I wamt to try to get the stuff back before i turn it in as i have important files on it. Anything welcome.
