I have all the components except the passive ones, so it has a little
progress since schematics, but I can not start the layout until I got
all the stuff I will use.
That looks like a pretty sweet project. I am personally working on a
board with a Spartan-3 or Spartan-3E FPGA interfaced to some RAM
(128mBit or so) and an LVDS LCD interface on a really small board,
which can be used as an embedded video card. The FPD-Link interface
is actually quite simple, just sending 3/4 LVDS data signals and a
clock line, and I think we could integrate it onto the OGP quite
easily. I am currently using an external RGB->LVDS converter, but I
could write some SW verilog into the DVI/VGA module if people are
interested in possibly making a daughter card for the LCD connection.
The one problem is that there are many different types of interfaces
to LCDs and almost all have varying connections to the main board. I
am only interested in a single display, so it doesn't matter for me,
but if we are trying to sell a board that has an LCD interface, it
might cause unwanted havoc with people thinking they can just plug in
the LCD and go.

This and numerous other sites continue to tell people that building
their own interface is not worth it, and they should just buy an
external monitor. If we integrated a laptop interface into an IDC
daughterboard, it would be very easy to get a large group of people
interested in buying the card. With the current number of I/O
available on the daughtercard, it would not be very difficult to also
have other extensions of interest on a pass-through board, or on the
same board as the LCD interface.
