Chaipi,
I have on occassion run into LCD modules in which the entire
pin layout is mirrored or reversed. Almost always it turns
out that they are compatible with the "usual" type LCD.

I think the pin reversal is done based upon which side of
the PC board they want to place the connector.

If all the pins are consistently mirrored or reversed,
assume that it is software compatible. Besides, if it
is NOT software compatible and you have no data sheets, it is
effectively useless to you.
