The PY32201 320x200
DATA IMAGE is one of the most famous LCD manufacturer in the world.
but, there is absolutely no info about this product. Why I have to Reverse Engineering an PY32201 LCD Display.
I guess there was a Custom Graphic module



Poduct of Reverse Engineering
This is Result  & Works perfectly


Reverse engineering


I'm gonna show you how to reverse engineering an unidentified LCD Display Module.
Don't worry, Hi-Tech. Not Required, Just need Common Sense and Google.

PIN SIGNAL IC Pin# NameFUNCTION
1 NC U1~U7 62 DISPOFFB(YDIS) Display OFF control
U10 3 SHDN  
VDD Via 1M Resistor  
2 FLM U1 66 D4_DR First Line Mark (YD)
3 CL1 U1~U7 72 CL1 – In common driver application mode,
   CL1 is used as a shifting clock of common output data.
– In segment driver application mode,
  this signal is used for latching the shift register contents at the falling edge of this clock pulse
4 CL2 U4~U7 70 CL2 Clock pulse input for the bi-directional shift register.
5 V0 U1~U7 55 VEE  
6 VDD
