Assuming you have removed the old laptop screen from the lid of your laptop, you’ll find the LCD model number usually on a large sticker on the back of the screen itself. The laptop screen model number is usually the boldest thing you’ll see on the back of the LCD panel and should be around 10-15 digits long.

All LCD Screen manufacturers have their part number at the back of the screen. Once you remove the screen from your notebook / laptop, you should be able to identify the manufacturer of the screen.
