DQ77KB edp port to LCD

Hello,

Ive been researching about the onboard eDP port and its connection to LCDs and came across a problem that cant seem to find an answer to, maybe can find some help here,.

I have found a few edp panels that I might be able to use with the dq77kb but all of them have the same issue. When I check the spec sheet of the panels, I see that the backlights mostly require 27V of DC power nominal for the LEDs. However, the spec sheet of the dq77kb states that it provides 12v/19v of backlight power. I have looked into seperate LCD controllers and all of them have onboard DC to DC converters that apmplify the voltage for the panel, but I wasnt able to see anything about this on the dq77kb spec sheet. So, I can make the data connection between the dq77kb and the LCD but how can I make sure that the power for the backlight will be enough? Has anyone found an edp LCD that works with this board? Any ideas?

Thanks.

Hello,

Thank you pointing that out. Unfortunately, the document doesnt state how the cable was hooked up to the panel. I am guessing that there was a board in between the motherboard and the lcd, but I cant find information on this:(
