Using the displays is just like any other parallel LCD you are used to, except instead of sixteen interface pins - there are eighteen. Pin 15 is the anode for the RGB LED backlight, then 16 to 18 are the cathodes for red, green and blue.
You can then treat the backlight like any normal RGB LED to create the color you need.
