I have been doing a bit of research in to this and I am super doubtful this is possible, primarily because there are no existing adapter boards that do this… and if it were possible you would expect there to be. What is super frustrating is how many LVDS/HMDI/DP to eDP adapter type boards there are, but this seems to be missing.
I would basically like to attempt to drive an LCD that is 2 lane 30pin eDP from the motherboard. Now that you can get the cable from Framework connecting a third party 40-pin display should be relatively trivial (so long as it adheres to the standards).
From the pinouts on the 30/2 and 40/4 eDP connectors it looks like you should be able to just wire up the 30pin to the correct lanes in the 40 pin - but I can find no reference of anyone doing so online.
So I’m just making this topic to see if anyone here who is a little more familiar with the standards can weigh in as to why this isn’t possible, or if there are any other solutions (short of using a separate driver board - which is my current solution, but it dumps unwanted heat into the enclosure I’m making and takes up far too much space)
Edit: Also, if anyone has the datasheet for the 13" Framework panel (NE135FBM-N41.pdf) I would love to have a look, it’s a paid download on Panelook which is a shame.
Managed to get some credits on Panelook with my business email, downloaded the datasheet which I have shared here:
edit: So… short of the knowledge as to why this probably wont work I went ahead and designed an adapter on EasyEDA and ordered some boards. I have a couple of ‘spare’ displays from this ongoing project so if I fry one it’s not going to be the end of the world.
I fully expect someone is going to come in and tell me that I just wasted the time/money/effort in doing so, but what can I say… I’m inpatient
