6.4 Display connectors (Internal)

The KTQM67 family provides internal display connectors: one on-board eDP (Embedded DisplayPort)
and one on-board LVDS panel interface.
For IO Area Display Connectors (DVI-I and two DP's), see earlier section.
Two graphic pipes are supported; meaning that up to two independent displays can be implemented
using any two of display connectors (IO Area - and Internal connectors) with the exception of the
combination eDP + LVDS.

6.4.1 eDP connector (EDP) (J38)

The eDP connector is based on single in-line 40 pole connector type TYCO 5-2069716-3.
