I know computers to a point, but I couldn't tell you how to do this. Reason I'm replying, is that do you know for sure it can be done?
As in, do you know if all laptop screens work on a standard type of interface and not a proprietry one? If the latter you'd need some very detailed documentation about the laptop's screen. Also, standard or not, the interface to a laptop screen will no doubt be a totally digital one, and if you want it to work with any computer you will need to fit an ADC (analogue to digital converter) into your monitor interface too. (i.e. a standard 9-pin D VGA connector on a PC gives you an analogue signal, which needs to be translated into digital because a TFT screen works by address individal physical pixels). Alternatively, you could limit yourself to making your laptop screen into a DVI screen (digital video interface), such that you are limited only to computers with a DVI port (= expensive grahpics card). At least it gets you out of having to mess about with analogue.

Out of curiosity, how would you control at least the brightness and contrast since a laptop monitor doesn't have these things built in; do they?

Sorry if I'm saying stuff you've already thought of, just thought I'd point out a few potential pitfalls!
