how to make a monitor from mobile screen?

I want to convert my old (dead) mobile's screen to receive video signal from AV cable of parking camera in my car!
any ideas how to do it, tuts, advices would be appreciated.

same question here, mine would be an htc hd2 :


You'll need to find a specialty converter box that will cost more than a screen already capabale of taking an AV input.

What did the screen come from? If it's from a laptop you'll need the driver board for the screen which is built into the main board of the laptop. Then you would need to buy a compatible converter box that would cost about as much as buying a small screen that is already AV ready.
