Yoga 2 11": upgrade to FullHD, screen connector schematic?

Hello, I have a Yoga 2 11 (20332/80CX) with a broken screen. Currently the screen is a B116XAT02.0 with a 1366x768 resolution, while I would like to install a full HD screen on it.

The screen has a 30 pins connector, but only 15 pins are used. On the motherboard it's a 40 pins connector labelled as "JLVDS", there are 15 wires for the screen + 6 wires for the touchscreen.

There are three things that bother me:

• I can't find the schematic for the motherboard, so I don't know if I can add the second channel needed for the HD resolution

• the little information I was able to find on the screen show it should be a 2 lanes eDP (and not 1 channel LVDS)

• on Aliexpress there is already a full HD screen exactly for my model, but it was never commercialised with it

Thanks

 

Small update; I asked for the schematic on Lenovo's live chat but they couldn't help me, they only had the hardware maintenance manual.
I contacted the seller on Aliexpress to see if they have a special cable with the screen.
