Hi,
all displays sold by FriendlyArm require a NanoPi 2 (perhaps because of it running on Debian).
So not even Neos bigger brother M1 (Neo+GPU+HDMI) is mentioned as supported.
On the other hand simple Arduinos are able to drive LCDs, it is just a question of having the needed libraries.
Once I did play with Arduino and the very small (84x48 monochrome) Nokia 5110 display based on this youtube video, that provides complete code to drive the display:

So you may take eg. a popular 320x240 LCD and port the Arduino library to Neo. Or you try RasPiArduino or PiDuino library projects to compile the Arduino code for directly running on (Raspberry) Pi and see whether they work with NanoPi Neo as well.
