As a sidenote - why is a converter for eDP needed in the first place, other than to supply power for the backlight, and to adapt the connector to the usual flat cable?
If I read the Wikipedia article correctly [1], eDP is a superset of the DisplayPort standard, with added functionality to control the panel/backlight via the AUX channel and support for an on-panel framebuffer - so in theory one should be able to directly drive an eDP panel from a DisplayPort connector with a passive adapter and some way to supply power to the backlight.
