    HelloI have the same 6-pin LCD coming from a fax machine with L303646 marking and I guess it's something like ST7032 or PCF2119x chip on glass controller. But the only problem I have is for the pinout... It came with a little PCB with the following markings: CMKM-P3X B53K463-1 and this PCB has two connectors labeled SEN1 and SEN2, maybe connected to optical sensors. On the LCD i've identified power lines, 2 connected to GND and 1 connected to VCC. The three other line are obviously SDA, SCL and contrast, but these lines are connected to an unknown IC labaled PNL7 LG2563 0039 M59 and I didn't found any info on it, I think it's a proprietary MCU or I/O expander.
