Re: display

What is the model number of your display? I can read it and tell you.

Cathode if the common is +v. Anode if the common is ground.

Re: display

Well if you dont have model number, you can test it with multimeter, but you will have to know pinout... Or just the common pin...
But usualy there is a model number, just type it in google and the results will come out...
