**that uploaded by mistake for some reason it doesn't let me remove it**

Hi everyone!

I have n old lcd display laying around that i try to reuse it. I have no idea from which device i took it..

so what i know:

-there is sticker with the text "7127FFA" on the back of the screen - found nothing in google.
-in the glass (almost impossible to see) i found "NCOG39" writen intothe glass - again nothing in google.

-let's number the pin from 1 to 8 when the pin near the red dots is pin number 8. I tried to do some measurments on diod mode, and i found that if choose pin 3 as ground and and run with the positive prob o the other pin i get those results:
pin 1: 0.62v
pin 2:
pin 4:
pin 5 to 8:
