Laptop screen as multimedia monitor?

I've got an older laptop computer that I don't use anymore, not really worth anything. I was wondering if I can salvage the screen and use it as a monitor for a multimedia install in my car. The screen is in good shape and it's about 15" diagonal. I just don't know anything about hooking it up to a source unit. Has anyone out there ever done that or know where I can turn to get info on how to do it if possible?
