@nazmulisla38051 could be a broken LCD, a loose connector or even some board damage. It all depends on how hard it fell and the comment by @timtomissus would shed more light onto that. So let us know about those details. Use something like [https://www.youtube.com/watch?v=r4lbC8_O9hs|this video] to remove the LCD and it'll allow you to inspect your connector. Make sure it is fully seated and that the LCD flex is not torn etc. If all of that checks out ok, I would suggest a LCD screen replacement.
