Screen not displaying after drop, how to get past password?

Hey guys, I dropped my phone a few days ago and it the screen slowly lost its ability to display anything and now its pretty much pitch black. I didnt realize that would happen so i didnt backup my files when I could. Now when i want to use keys, it wants me to unlock my phone and .... I cant. I tried finding a solution to this but to no avail, please help. :crying:
thanks in advance
