Hi,
I'm doing hard to finally find a cheap (<6$) TFT LCD for my Arduino!
I've invested 24$ up to now in my big search 
That means 4 non-working LCDs due to "unknown chip", with sellers not cooperating, not giving any information (upon complain they only suggest a full refund!)
Now I received 2 new ones I even didn't pay for them, perhaps by mistake sent to my address by an unknown seller! I turned internal part of these and found finally first time something written on the film-flexible-PCB:
FPC2603715
Google gave me only this link:

While the LCD in the picture is not what I got by visual parameters, the chip name is the same. The look of the LCD is exactly this:
I can't find any driver code for Arduino, anyone please dealt with such LCD and could possibly tell me where to find it, if google doesn't know?
