Try searching for "industry standard alphanumeric display controller". :)

You have stumbled on the standard character mode LCD display.  '44780' is
the Hitachi controller that is very common for character LCDs.  Also, the
14 pin interface is a good sign that it is at least a 44780 copy.

Seriously, search for 44780.  There is LOADs of info, pic code, an
application note on www.microchip.com etc. Needless to say, I never got
mine working... :(
