IIRC the HD44100 is often used as extension (slave) for a HD44780, or as
slave for graphical controller chips. It is not a controller, just a
driver. You have to supply the pixel data, over and over, at the right
frequency, and with the accompanying clock signals. Definitely not
recommended for a 'first go' at an LCD.
