You will need to make some sort of connector interface;the lcd isn't hardwired but usually connected to the laptop motherboard video by a flexible flat fragile looking printed circuit .
There is(was) a video processor being sold that would take various kinds of composite,s-video,and 15 pin rgb and out those to 15 rgb.The Viewsonic N4 which cost me about $100 two years ago.
Or find one of the lcd TVs with composite inputs;the discount store in my little town has one for $159.15 inch.
Good luck.
