How to hookup LCD from PC to in-car DVD?

I have a Samsung LT141X4-156 LCD 14.1" display out of a laptop PC and was wondering if there is any way to hook it up in my van.  I have a Pioneer DVH-P7000 Head unit.  I basically need to know where I can find some sort of interface.  I have the actual cables from the pc, but thats it.  I know it ultimately needs to be converted to RCAs to work with the head unit.  Also, how would I go about supplying power to this thing?  Any thoughts or suggestions in the right direction would be appreciated.  Thanks in advance!

What you'll need is a composite to RGB converter, and most likely this will not be cheap.  This is of course assuming your LCD uses an RGB input, which if it's from a laptop it almost certainly does.

I think what you need is something like the 2nd converter listed on this page.  I have no idea how much it costs though, and you'll wanna make sure its output will be compatible with your LCD.
