how i use this lcd with arduino uno !!
Personal opinion: It looks like a T6963 controller. maybe u8glib will work.
Note: Connect FG and FS with 0V (GND)
Question: Connect 5V to VCC and 0V to GND. Measure the voltage between Vout and GND. Is somewhere between -12V and -18V?

It will be easier to identify with better pictures !
