i was wondering about the same thing as well. i wanted to mod one to fit into the side window of a computer case. i have lookind into it it a little, and what i have found are:
1. costly
2. very difficult
i think in order to get it to work, you would first need to know the brand/manuf. of the lcd screen. then (i think) you need to find the proper inverter and controller card. there may be a few other parts you need, though i really dont remember... i kind of lost interest after i figured out how much time and money this would all cost
