Looks like a graphic LCD w/o controller.  You can find a controller here:

But you can probably also use the epson 1330 (digikey has it).

Basicly you have the drivers for the LCD on the lcd itself, but nothing to tell
the drivers what to do.  Typically the controller refreshes the entire panel 200
times a second by clocking in four bits at a time.  There really isn't too much
on the internet about controlling your own graphic lcds, mainly info about lcds
w/ controllers in them.

I hope this helps!
