OLED Screen in a P775, P770, or P750?

Do we have 5V anywhere inside or how creative would we have to be to get this thing working?

Hi,

I do not know much about these adapters nor AMOLED panels. But I think the most important question is how much current is needed for these panels to work? 

The most current you can get based on the SM of the P775 is the SATA 5V power.

The 5VS is limited to 2.5A which is maybe sufficient for the AMOLED. But you can not use any more HDD.

The PU8 is producing the 5V for the SATA, in the top right corner 4A is for the whole circuit branch you can not use all of it.

U58 MOSFET is a load switch for the SATA power but I think it is not in use default because PJ62 jumper is short on default. You can see the power limit is 2.5A. SATA_PWR_EN is default ON which means if it is in use you should have 5V on power on.

 

Conclusion is if you panel is not using more then 2.5A then you can use SATA 5V but you can not use HDD simultaneously.

Perhaps you can use an USB-C to SATA power cable, but I think it is very important to use a fuse(2.5A).

 

If someone with more experience with these adapters and AMOLED panels could help would be nice.

 

This is just my theory how these circuit work it can be incorrect!

Correct me if I am mistaken but this board merely adapts from display port to embedded display port which the laptop already has for connecting to the internal display, I am unsure the specifics of the pinouts for the AMOLED panel or what extra signalling or drive voltages it expects but perhaps it would be better to look at the panel compatibility with the internal EDP implement before resorting to a whole extra board
