Hi,
I recently pulled a Sharp LM20X212 display out of some junk we had laying around. I would love to interface this to a parallel or serial port, but have been unable to find a circuit diagram. A search on Google found only limited information, and I can't find any posts on here that look similar. I was able to find this:

I put 5v across the back light and it lit up, so it seems to be working. It has a 14 pin data interface. Any help would be appreciated.
