@ExperimenterUK
dude i really appreciate your help kindly would you like to tell me PG12641Dand XIAMEN 20 pin GDM12864A both are the same i didn't see any thing related to it in datasheets and one thing more as i have written before by using DMM i found out that Pin 20 is Anode of LED and 19 is Cathode of LED and this datasheet is opposite to it 20 is K and 19 is A

some times pins are swapped so that is not an issue led will not on if u swap connection nothing else will happen
u just start lcd is standard and i hope pins will be same as provided u should start it not afraid at least if control signals are swapped it will not burn use 5 volt supply

I thought the two were the same because this webpage said they were.

Unfortunately Sparkfun sell the GDM12864A and it looks different.

Data Image (http://www.dataimagelcd.com) seem to have disowned it,
but may help if you email them.

On the bright side, I have seen several adverts for the PG12641D which say it is 128*64.
It is likely that (apart from the back light) most 128*64 displays use the same pin out and
commands.

i tried that pin configuration and it didn't work at all
