[quote="JonnyMac"]Those kinds of LCDs require special drivers; you can't treat them like multiplexed LEDs.  One driver you might consider, an I2C device, is the Phillips PCF8566; ic can driver four backplanes and 24 segments. You can control it with the SX using I2C.

That one will do 4 backplanes and 32 segments, exactly what I have on the LCD. Page 13 is exactly the info I was looking for.
