Have you tried looking up the controller? Look on the back of the lcd for the chip usually has a number.

Where did you buy it!!! There can be two alternatives... Toshiba chipset T6963C or the Samsung KS0108/7 both 20 pin pinouts... The Toshiba pinouts are almost nearly similar, The samsung however isn't... I would be looking to the negative voltage convertor ( the little surface mount chip ) google the chip and look at the application examples... Find out which pin is the output, and trace it back to the main connector..... You will be able to find the 5v rail and ground in a similar fashion.... You will be able to find out the pinout from these deductions.

thanks for every one this is really amazing way to look for the chip to know what pins ! (it is TP7661) datasheet is attachment and i found out form comparing it with GLCD that VDD is pin14 form chip and pin2 in GLCD , VSS (ground) is pin7 from the chip and pin1 form GLCD so does that mean that datasheet is VTM-12864D ? because this is the only pins i can surely that is not wrong and the others ...?
