Replaced battery and broke the screen in the process

So I'm relatively new to trying to repair electronics, but it seems like a fun and useful hobby. My mom was going to replace her iPad because the battery wasn't really holding a charge anymore, so I thought I would take a crack at fixing it. I managed to get the screen off without breaking anything and replace the battery successfully. I reattached the ribbon connectors and the screen turned on, yay! I then powered it down and detached the screen while I glued down the battery (I didn't let the adhesive touch the back of the case until I saw that it worked because I wasn't quite sure I had the battery connectors completely in) then I reattached the screen and the brackets holding the ribbon connectors in and before I glued the screen on I turned it on one more time and the screen wouldn't turn on. I took off the brackets and the screen connector ribbon popped right out. I figured I didn't have it seated correctly the first time, so I reattached it and tried the screen again. The backlight turned on, but nothing came up on the screen.

I think I may have bent the pins on the ribbon connector (although I couldn't see any damage with my naked eye, on either the board or the ribbon connector). My question is, should I buy a new screen and give that a try, or should I just cut my losses and take it as a learning experience? Or is there something else I may have done wrong that I could fix?
