Hey, I am a newb to this board, but not to LCDs. Your question is probably one of the most common LCD questions out there, and one that I asked for a LONG time. A priceless source of knowledge are the LCD forums at
http://eio.com/lcdintro.htm . Just check out any of the archives, and use "Find On Page" to see if you can come up with anything. However, more than likely, they are going to tell you the same thing over and over again. You need a controller card. There is no simple, or cheap way, to use a laptop LCD as a normal PC/video component display. There just isn't. The best place to find a controller card is at
www.earthlcd.com, but even then, you need to know some specs about your display other than what laptop you ripped it from. I think that ultimately you will learn it is easier to purchase a LCD monitor [Since, if you're like me, you want a large one.] and take it from it's case for your use. There are many reasons why you can't just just use some Radioshack breadboard and solder yourself an adapter. [And you can't use the controller out of the laptop in most cases either.] I hope this was semi-helpful. I know it isn't the answer you wanted to hear, but it's pretty accurate I hope.
Yes, you can use a laptop LCD as a display, however it requires complicated and expensive [~$200 or more.] controller cards.
