Help dropped phone

[asde33]

I droppedmy Galaxy S3 phone and the screen is black. What do I need to do now? I bought a brand new screen glass but fear it may be LCD or digitizer..... Which one do I need?

Does it still respond to touch and display images? If so it's just the glass you need to replace (check out youtube for guides) and don't stick anything under the bottom right hand side of the glass as there's a ribbon wire there. Good luck
EDIT sorry if just read that the screen is black. The LED is shot then.
If it was you I'd buy the whole display unit (glass, digitiser and display as it think that's easier to replace
