This can be a bit confusing! There are five cables. The eDP cable only jumps across from the main logic board to the T-CON board which is that flopping circuit board which has four cables. The two larger cables are the LCD driver fanout from the T-CON. One of the smaller ones is your backlight power feed and the other is the camera connection.

Chech out the middle image in Step 10 here [https://www.ifixit.com/Guide/MacBook+Air+13”+Retina+Display+Late+2018+Display+Replacement/135506] where you can see the five cables.
Sadly, your backlight cable has been damaged which is why the display needs replacing. It’s these four cables which are flexing every time you open and close the lid. Sometimes a good bang along the edge can damage things as well.
