The unibody’s use LVDS signaling unlike the Retina models which depending on the series is either eDP or iDP.
I don’t have the schematics in front of me right now but I don’t think there is a comparable chip in this series.
I’m not sure why you disabled the discrete GPU (NVIDIA GeForce GT 650M). The 2011 models had the crappy AMD Radeon HD 6770M which just didn’t hold up for quite a few reasons. That’s not the say the NVIDIA didn’t have its issues but I rarely needed to deal with them and the approach of disabling the discrete GPU is different if it’s dead.

I’m suspecting you likely have a different issue at play here. Are you able to boot up in Target Disk Mode? Just press the ***T*** key just after you start the system. At which time you should see either a FireWire or Thunderbolt Icon on the screen. If you get that far you know the Iris graphics within the Intel CPU is working. If not that tell me the cable and or it’s connections between the logic board and the display need inspection and may need repairs.
