Try this and let me know what happens please>This could be a glitch in the software and needs to reboot, lets try and force a reboot > Hold the home button and the power button down for about 30 seconds or until the Apple logo appears on the screen, then release both buttons.
okay, unfortunately that means the display has failed. Most likely broke a connection during the fall. You can get the display repaired. Do you have a local smartphone repair shop in your area?
I only do the tech support, i do not have access to any of the account info. Sorry.
