Dropped my iphone please give me advice urgently?

I recently got my iphone screen repaired and of course i break it again

i dropped it and instead of the screen cracking, the actualy visuals are white lines and sometimes blue and they are just moving. I can still unlcok me screen and type and stuff but i can't actually see anything.

what sounds wrong with it?

thank you

Added (1). A case in this situation wouldnt of done much as i dropped it on hard floor accidentally. I want to know what could be wrong with it and if it is fixable but thanks

You need to get a case for your phone to prevent you from breaking it… Get something like an Otterbox Defender or a Lifeproof case…
