With this in mind there is always the possibility that one of these boards happens to have the all required attributes (including correct led voltages), and a simple pinout converter board/cable could be made to work. This would obviously be quite an involved way to go but it depends how much you wish to use this specific panel, alternatively you could just use the ipad panel with an established converter board as XDjackieXD said.
You need a constant current driver for each backlight lane. Using simple resistors would work but will probably lead to uneven brightness and eventually death of the backlight...
Also the "just a physical adapter to DP" part is harder than it sounds as these are (very) high speed differential signals (just read this
story to understand that this is quite a steep learning curve...).
If you still want to give it a try I would suggest writing the guy I linked above and asking him for some tips and/or help (he seemed pretty nice when I asked him something
Thanks for answers.
Did NJY answer? or should I write from my self the request to them... I mean 45 pin edp is enough? or many more parameters to be mentioned?
For parameters at least the connector type & pinout is needed if they don't have a datasheet of your panel.
