chips with HEX 101 and C1C1, whcih driver?

Hello, I've got 3 LCDs off ebay and non is working with any kind of lib I found by googling for. Specially, I read all the posts of: http://forum.arduino.cc/index.php?topic=134708.45 and got lib from those posts: https://docs.google.com/a/ianaied.com/file/d/0By0GEVVJbBtSZktxaEtJZGNlcGM/edit because one of lcds is claimed to have the spfd5408 driver. But the result of any code uploading is the same: the white screen!

The seller is no way willing to communicate. One scenario is that all these 5$ LCDs claimed as spfd5408 driver are fake! Because the LCDs linked to from the above arduino posts are some 18$ or even 20$, but ones I bought are 5$ (but look exactly the same). Well but then it's crazy idea to think all those sellers are selling fake LCDs!

The other LCD is "claimed" on the auction page to have a 7781 chip and even code is provided: http://www.ebay.ca/itm/UNO-R3-2-4-TFT-LCD-Shield-Touch-Panel-Module-TF-Reader-Micro-SD-For-Arduino-/191346024531?pt=LH_DefaultDomain_2&hash=item2c8d1ca053

But the same result anyway, anyhow: white screen!

The serial test by code I found on this forum from first link I pointed to, has this output for 2 LCDs: 8 Bit LCD test! Unknown driver chip 101

the other: 8 Bit LCD test! Unknown driver chip C1C1

Could anyone please point me farther than stop point? Thanks in advance

p.s. the TFTLCD code I got for my other LCDs has a serial test for HEX code of the chip, and this is all info I get from it: 8 Bit LCD test!
