What kind of cable is this?

I was trying to replace the screen of my iPod 4th Gen (and all the stuff that comes with it) but I broke a ribbon cable (and maybe a second one?)

So what I need to know now is, which those cable(s?) are, so I know which ones to buy. It'd be great if someone could give me a link to the cable(s?).

Here is the image: (I used paint to show you the places where the cable(s?) are broken)

Edit: I just noticed that I removed that black stuff under the upper ribon cable (thought it was just some glue, do I need this?))
