What is the model number of the 2880x1800 LCD?
What is the model number of the 2880x1800 LCD in the new mac book pro?
I am trying to purchase the LCD from Samsung (or whoever makes it)
Are you capable of examining the LCD's signals with an oscilloscope? I would like to know if it uses traditional LVDS or embedded display port signalling.
If I can get a panel and make it run, I have a friend that can sell you a 2880x1800 resolution projector.
Update
The LP154WT1 (SJ) (A1) GD has a 30 pin connector, and it looks like there isn't an extra connection for the LED back light. (back light must run through the 30 pin)
The cable looks very similar to the embedded display port cable used on the B131HW02 V0 panel. Since I believe that traditional LVDS signals would require more than 30 pins on this panel, I propose that this new panel must be using eDP.
I am already working on an adapter that could be used with this panel. If I can confirm that this is eDP I should be able to drive this LCD in the next few weeks if I can get my hands on one and the datasheet.
With eDP, this panel would only need 10 DP signal lanes, a hot plug detect, a power supply (probably 2.5V), then the rest of the pins can be used to power the LED backlight.
If anyone wants to experiment, if you can power the panel on (and receive the hot plug detect output) you only need to plug the AUX signal into a display port for it to be detected with the EDID.
Is this a good question?

I am close to getting an adapter into production for a different LG high resolution eDP panel. I have some custom manufactured IPEX cables for it so the signal quality should be very reliable through the adapter (unlike any potential DIY attempts). I will report back when I receive boards and get to test the LCDs.
