"easily driven by an AVR or PIC type microcontroller" ... Hmmmm ... the main feature of the HD44780-type alpha LCD is that it is a static device, containing its own memory. The content is scanned by the hardware on the interface board.
If you want similar functionality with a mono or color big size LCD, you have to have something in the way between the AVR and the LCD itself that is going to retain a display memory so that the LCD can be continually refreshed (and don't try to do that with an AVR). You could do worse than putting an FPGA board in the way with a VGA interface on it - that way you could drive any number of LCD monitors .. talk to the FPGA via a serial protocol of some sort and have it maintain a color alphanumeric, or alpha + limited graphic display, or with enough memory a full graphics display. Boards like a papilio (http://papilio.cc/) with a VGA wing would do the job.
