it was usd 230, at least twice the expected price, but thats secondary parts market for you. I will get a display port splitter (one that does stream split and not just mirroring.): first for the two eyes and second hopefully for some electronic shorting separation from an expensive display port source.
My main reason for the topic is to ask if anyone else has done this and what problems were encountered.
I have worn out my google eyes looking for eDP hacks: there is but one lonely 10" iPad retina example.
Surely the awesomeness of this endeavor would cause more hackster outcomes.
if the S4's panel has a tiny driver ic in there somewhere then it should be straightforward after finding out the signal and power traces. Does the iPad retina LCD have any timing ic or eDP receivers on the panel?
I was looking at one of the S4 panels and saw "AMS499QP01". Do you think that might be a ic model number like a driver ic or timing ic? Maybe it's in the housing.
I don't know about it yet, we need more info. In that link I posted there is also this though which is VERY specific in display specs/timings etc... which will be needed later regardless of panel interface:
On mtbs3d and this forum there was talk of two potential circuit makers. rozsnyo(ipad edp hack circuit builder) and chalkboard-electronics. There's also the possibility of an independent designer. OzOnE2k on mtbs3d did a design I haven't checked out and for all I know It may be almost done.
I really think a universal circuit(that we could attach different display cables to in case the pinouts are different) would be best so we can use different panels instead of designing for just one panel. That way we can use later 1080p displays of different makers and sizes. If all cables are the same connector and pinout then that would be amazing, but I don't know.
EDIT: ok so i looked at different 1080p mobile display panels' cables/connectors and they're different so a universal connector will need a custom cable for each display.
