You can get the model number of the LCD monitor from the back of the LCD panel after you extricate it from the plastic frame/wiring.The wiring is not needed as all wiring comes with the new driver board. Order the driver board for your model of LCD panel from ebay or Ali Express for (typically) $25 to $37. Remember to order one with HDMI if you're planning on using the screen with a Raspberry Pi. The touch detection on many screens is a function of the clear cover over the screen so unless you can contrive a power supply for its interface board and find/write a driver to get it working, then that touch screen part of your old laptop may not enjoy a revival. The only issue left then is setting the language of the control board menu from Chinese to English when you get it all plugged in... it's not very difficult. It's a cheap and fun way to get a great monitor.

there is a seller on ebay who sell adapter kits, you have to tell him the specific model of your laptop and they make a kit for you for about $30. They were selling these when xp was the latest os, so touch probably isn't supported. After a quick search for "touchscreen Controller Board" apparently most touch screens can be controlled by 4 or 5 pins such as this $10 amazon special, although most links seem to be for adding a touch screen to an existing monitor.

$30 for vga adapter+ (pessimistic) $25 touch adapter= $55 < $170 amazon price for acer ft200hql 19.5inch touchscreen monitor

Or... you can sell them on ebay, part them out, sell as-is, or pair them as a lot. The screens break more often then anything else it seems so if you can guarantee those work they should sell.

You can't. Monitors have hardware that help drive the screen. Unfortunately this hardware is typically built into the main board on laptops. On rare occasions you can find LCD driver hardware that is compatible with some LCDs screen but you gotta be sure to match it with the screens you have. On the touch screen side it's the same thing. You would have to find compatible hardware that will work with the touch screen overlay used on the monitors. In the end you would be spending more money then it's worth. If you don't want them to go to waste then sell them for parts on ebay.
