Hi
I have 4 of this LCD, need help to use it.
Originally is from GE Caller ID display 4line*16 or 20 Character !?
9 pin including GND, VCC, LED backlight and DATA lines.
so 2 for the backlight, 2 for power, and ~6 for data.
Can't figure out how to use it, I don't have the pin out of this LCD.
This is the 3 day 10hr/day to try to make it work.

Made by Samsung
UC164904-GLHTX-A97050906

I think is serial or I2C interface !

I have this lcds for 2-3 years, contacted with Samsung many times, they say its made by Samsung for a customer, most likely GE has the datasheet. GE simply ignoring my emails, this is not our product. :x

Please help if you can !
Thanks
Steve

Not sure when you posted this but I know the type of display you have;
I believe the chip type is similar to the Samsung KS0074 / KS 0708.
4 lines 16 character/line. ( at least for the -A97061206)

You can find a data sheet on it in Google , pinout is standard:

1 ground
2 vcc (+5V)
3 V-lcd (bias, ~3v, use divider 510 Ohm/ 1kOhm
4 enable (low) connect to ground
5 data in (serial)
6 serial clock
7 data out
8 LED anode (+) use resistor to +5V
9 LED cathode (-) to ground

Good luck and I hope this helps.
