Graphic LCD with unknown supplier code

Hi everyone.
I recovered two of these graphics LCD and would like to reuse them, but unfortunately I can't find the documentation.
They have 28pin, but I can't know the driver they use or the corresponding pins.

I would like to communicate through SPI.
Can anyone help me, or have any idea how to proceed?
Thank you.


I used to keep displays from old printers, routers etc, like 128x32 dot matrix, I knew their pins and how to drive them, but I still had to buy adapter boards with the proper connector, and it's more expensive than buying a display module for arduino :confused:

I think it's not worth spending your time and money on this

Agree.

+1, With no data sheet it seems unlikely to be successful so a waste of time.
