Most modern PCs don't have a parallell port, so if I was you, I would use a serial interface which is easier to come cross in the modern world.

The trick is in differential mode. The faster serial buses like USB, firewire, ethernet etc all use differential pairs for data. Differential mode offers a lot more noise rejection besides cancelling rise / fall time delays.
If a parallel bus is designed with differential signal, it would be too expensive. But you can get very high data speeds.

Just a 2 cents idea: Use a CPLD to convert your serial stream to parallel.
As an example a simple EP3064 from Altera would do the Job.
- A CPLD could have a state machine which would initiate your LCD at startup.
- It would take care of the low level handling.
- If you change the LCD in the future, you won't have to modify your h
