There are several answers to this. Most off the shelf character LCDs have an 8 bit interface. That means there are 8 data pins. But if your processor lacks enough I/O (In/Out) pins you can use just four of the data pins. There is also a SPI interface with only has a few data pins.



On other display technology such as a TFT, there may be 16 or 24 data pins.
