Can I repurpose some parts off of an old compaq laptop?

I had an old laptop (about to throw it away but i stripped it beforehand). It had a cd drive and some other junk i prolly won't use. I want to take the screen and keyboard out and see if I can do anything with em.

Now heres the meat of the question. How, or more importantly can, I take the screen (LG Phillips LP150X08) and wire it to my current laptop with a serial port (serial right? the one i can plug an external screen onto) and use it as an extension of my screen. Part 2 Can I take the keyboard and wire it to my laptop (PS/2 or USB) it has some strange ribbon cable idk what to call it. I have the mobo and all circuitry from the laptop if that means anything. The pic is of the screen with cables coming off of it. The little i shaped connector thing was from the wifi signal ignore it. also the screen has a bunch of circuitry at the top. If you need any more details feel free to ask.

0) No, it isn't the serial port,. it's the video port. Serial is something entirely different.

1) You probably can't connect the display to your current machine except by using the whole laptop.... which, given that you stripped it, you no longer have the option of doing.

The LCD needs driver electronics. In a laptop, those are generally tightly integrated into the motherboard., and can't really be separated out. You could build new driver circuits, but that's going to be more expensive than just buying an LCD monitor.

If you *hadn't* stripped it down, you could have connected the two via network and run software which set up a screen buffer wider than the physical screen and copied the extra out to the second machine. I'm not sure that software to do this is available off the shelf, but conceptually it's certainly possible, given applications like X-Windows, Windows Remote Console, and VNC.

2) Reusing the keyboard may be easier. A keyboard is essentially a matrix of switches and diodes. With suitable hardware -- a specialized scanner chip or a microcontroller programmed to play that role -- you can detect the keyboard's state, and by comparing it with the previous state notice when a key has been pressed or released. That information then gets formatted as serial data and transmitted using the appropriate protocol to the PC. Feeding the PS/2 keyboard port will be simpler, since I believe that's just a serial data connection. USB protocol is much more complicated. Again, this would have been easier and cheaper to do in software via a network connection.
