Faulty screen

[Leonardo Pablo]

Hello all, was hoping to get a little help. I recently dropped my mac from no more than a foot and booted up and everything was fine for about an hour then the screen started to judder and get a bit jagged and sketchy, it does this and just gets worse. I'm not too good with these things so any help or advice would be greatly appreciated. I've uploaded some pics of the sort of things it's doing, nearly bought a new one the other day but decided I'd try here first

Thanks in advance for replies

what happens if you reboot it?

I happens everytime I boot it, left it for a few days at a time and nothing happens. On boot up the apple logo is even a bit jagged with pink pixels in it
