Is There Any Libraries, What Hardware Do I Need?

Have a look at "blink without delay".
Did you connect the grounds ?

The answer is, you don't. An arduino is nowhere near fast enough to control such a display as the display has no controller built in - you have to generate the pixel clock, HSync, VSync, Data Enable, and data pins.
I tried such a thing before (different screen, but same principal) using an arduino and even with near perfect optimisation of code I could only get to 1/10th the required pixel clock frequency which is so far out of spec that the screen won't accept it.


EDIT:
Interestingly actually this is an Analog display not a digital one (FG020510A). But still, the clock rate required is far beyond the capability of an arduino.
