9 pin lcd display factory

I bought some text LCD modules without spec sheets or obvious part numbers. They all have a series of connector pins, unlabelled other than a 1 to indicate pin 1. I was able to get the one with a Hitachi driver and 16 pins to work fine, and now I"m trying to get a 9-pin lcd to work.

Pin 8 is clearly A for anode, possibly for backlight. Pin 9 is K for cathode, again possibly for backlight. The other 7 pins are unlabelled besides the 1 and 9 indicating pin numbering.
