This is still unclear to me.

I assume you are referring to the display at 3f?
I can see many other panels use display@<address>, e.g.
elgin,jg10309-01.yaml
and 
sitronix,st7735r.yaml

Those are using address 0, but that is because they are SPI devices,
this is a I2C device and address 0 is not valid. 
There are plenty of examples of I2C devices using the real addresses in the
node name.

Or do you want me to call it panel at 3f ?
I can go with that if it is preferred.
