Maybe consider using SPI for driving LCD, see [url=http://www.mcselec.com/index2.php?option=com_forum&Itemid=59&page=viewtopic&t=9091]this link [/url=http://www.svet-el.si/english/index.php/data-displays/31-data/14-avr63]or [url]this link[/url], where using LCD on an SPI was described.
I could drive more LCDs with only 3 pins used on a uC.
Best regards
Jure
