I have never done this, but in theory you would need an driver/adapter board for your LCD model.
On the back of the lcd panel should be a type number.
With that it should be possible to order a driver board eg. on aliexpress.
Usually those boards have vga and hdmi out and the connection to your lcd panel.
Erich, I also have a couple of those old broken notebooks and had a look at those drivers Tina mentioned (btw. there are some in 10-15 USD range and some 30+ USD).
I checked nearly all of those cheaper ones but could not find a compatible one for any of the LCD's I have. Be careful, it is a Russian roulette. Make sure they have a download for drivers (you have to flash them) and check inside the given file for your model number...
