Hi everyone.
I have couple LCD displays and
i was going to connect them to my pc but i cannot find
any information about them....

I have 3 LCD's and here's some info about them...

1. Display: is made by SEIKO, it's 4*40 and it
has HD44780A00 chip on it.
It haves 16 pin connection (+ 2 pins for
backlight i think)

Email the dude, and he'll give you all the info you'd ever want on them, as well as the prices for controller boards or any touchscreen overlays you may want.
