Hmmm, we got HSync, VSync, a pretty much standard framerate, you just had to 
convert the 5-6-5 databits by 3 DA-converters (maybe R-2R for the cheap 
solution) to form RGB. Some level shifting, attenuating, maybe inverting, 
should be pretty much feasible

If you really want to do that, ask me for details of the FPC-cable signals and 
pins, to build your own "LCM" that plugs to the PCB-connector instead of the 
NEO one.
