My iphone screen went black, but the phone is still working?

I was using my phone all day long and it was working perfectly. Then all of a sudden the screen went black and I thought the screen just dimmed down, so I hit the lock button but it stayed that way. Every once in a while it would light up for like one second when i got a text, but then go black again. My sound still works and everything just the screen is black. What can i do?

Call apple 1-800-MY-APPLE

Sounds like maybe a problem between the phone's digitizer and the computer inside the phone? I have no idea, really.
