Shenzhen Anxin (an LCD module reseller) was giving away some LCD screens (without documentation). So I got them at the price of shipping. And… here it is.
One comes broken, so I started with that one. ITO traces cannot overlap, means it has to follow the sequence of the COG chip.
The pinout of ST7565 die is cs1 cs2 vdd rst a0 rw rd vdd d0-d7 vdd vss vout n*vcap v1-v5 c86 ps
So we can guess the thick pin 2 is VDD, one CS, one not connected might be RST, then A0, RW, RD.
Note the RD ended with an via. Now we basically have the pinout. Just try to drive it and see if it works. And it turns out it worked.
