Distorted images on Macbook Pro?

So, a few days ago, my laptop slid off of my passenger seat while I was driving (careless, I know). The day after, when I was using social media, I realized that people weren't posting bad pictures, but the images were actually just showing up distorted. On Facebook, most pictures show up mostly white, with discolored outlines. On Tumblr, most images show up okay, but they'll have a grainy rainbow overlay (it's almost like the rainbow occurs on the pure white parts of a picture). My pictures in in iPhote have the same issue as Tumblr. However, gifs and Netflix are flawless. Text and everything else looks perfectly fine, even the apps at the bottom show up fine. Only the bottom left corner of my background is a little distorted. Is it possible that something was knocked loose? Do I need to get something replaced? Has anyone else experienced this? Any guidance at all would be greatly appreciated!
