Hi i got a GLCD from my friend but i'm unable to find its datasheet on internet the only number written on GLCD's back is " PG12641D Data IMAGE".
Can any body help me to find out datasheet of this GLCD and also guide me how to interface it with 8051 as i didn't use GLCD before or provide me some initial data for my knowledge simulation or Assembly codes for GLCD????
Thanks

@ Mohsin_776
in assembly it would be tough job
normally all GLCD and LCD has same configurations
its pin configuration is mentioned at the back of lcd
ground pins are mention as well as vcc
it has some extra pins as compare to normal LCD

I doesnt look like those are pin configuration.. i feel they have mentioned connections to backlight LEDs and related resisters. extra pins are usually for backlight LED connections.

@Mohsin_776 Please use proper forum when posting topic

Nothing is written on the back side on GLCD as i have posted picture you can see as well.Till now i only mange to find out that pin number 20 is A(LED) and19 is K.
as you said this is not similar to LCD it is 20 pin and i have found number of datasheets each have different pin configuration and voltage levels which makes me more confused some says Vcc is 9 volts and some says 5.
please kindly help me in this regards if you can @Ajay Bhargav leave these small things and try to help me out please

@ Mohsin_776
the other pins u can find out using the above picture
use 5 volts first u will guess then is 5 is sufficient or not
better that where u buy tell him about data sheets
or at least tell th name of lcd by which u can search on net

Try the following pinout. I got it from some distributor. I don't have the datasheet for the same.

The PG12641D is also known as the XIAMEN 20 pin GDM12864A 128x64 display
The data sheet for the KS0108B controller should give full programming data.

These might help
