It would also help to know the manufacturer and/or the OEM source for this display. The part number leads me to guess that this is a graphics LCD with 204 pixels by 64 pixels. To understand how to interface to the display you are going to need two data sheets. First is the manufacturer data sheet so you know the pinning of the display connector. Second you need data sheet for the LCD controller on the display so you can see what commands the controller supports and how the communictions sequences to the chip work.

I am going to guess that this display possibly uses the Toshiba T6963 controller. If so the data sheet is easy to find via a Google search with T6963 as the key word.
Hope this helps
