Color TFT interface is pretty simple, much like CRT video interface but

Color passive display interfaces are a real mess...

All 4 of the laptops I've dismantled had ribbon interfaces much like
the floppy cables. I have no idea what sort of signal drives them. The 8"-9" lcd screens from 486-era
laptops come to mind.

Are they hard to interface to? do you send them
video?
I _would_ like to know what that type of cable is properly called.
Flat mylar(?) with applied traces, not wires, attaches to the PCB with a
clamping header?
Doc
My literature refers to them as FFC's (Flat Flexible Cables)
We use some .5mm pitch ones for interfacing to small LCDs
