Well without a picture of the display it's really hard to search for a datasheet
because I can't compare the dimensions and connectors.
First have a look at the connectors. I think CN1
should be tha usual
parallel interface. Is it connectet with the T6963C?, if yes it's the parallel interface
with backlight (mostly pin 19 and 20).
And if CN2 is connected to the T6963C too, maybe through another chip, your display
has a serial interface too.
Most displays wit T6963C on board have similar pinouts. Therefore it's not neccessary to
find exactly the datasheet of your model. I've found two in the internet. One is the A-Model
and one the B-model. Both are SG240128.
If they don't fit, try to find the GND pin with your multimeter and maybe grab the
T6963C datasheet which helps you to find the VCC pin.
If you have those two, compare them with other T6963C-LCD-datasheets and you
soon will have your pinout.
