Apparently, your screen is badly damaged. You probably need to replace it.
A question:
Was it ON when you droped it?
Droping a powered up laptop can irrevocably destroy it's hard drive, and will, at least, damage it causing some data loss. If it's a SSD drive, you are safe on that point: No moving parts.
