Samsung S5 No Display, But Blue LED Light Shows, And Notification Vibrations Also Happen

[AC Question]

So I dropped my phone. ):

And I tried turning it on to see if it is fine.

I feel the notification vibrations, and also when I turn up the volume, I hear the volume being turned up for System. The blue LED light next to the words Samsung on the phone also flash as normally.

Anyone know what happened?
