This has all been discussed before, so use the search function for a more detailed description. The Laptop LCD will need a separate controller as they are built into the motherboard. This controller can cost upwards of $300 (ouch!) so check out www.earthlcd.com for a rough guide. As far as I know, there is no way to get the controller off the laptop motherboard - I have a pc chips controller on a laptop which I can't use for this reason. If the metal sheet is on the laptop's plastic and not part of the actual screen module it could be insulation or grounding or something - I wouldn't really worry about it. Unless you can get hold of a rubble controller it probably isnt worth using your laptop screen. Bummer.
