Determine Your Part #
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. The rest of the guide should help you identify the OEM part number from the many confusing numbers found on the back of the screen.
On the back side of the screen you can see one or several labels with numbers. Almost every screen on the market today have manufacturer's code and screen size included in the model number. You will need the manufacturer part number to find the right replacement screen.
For example a Dell XPS 15 (L502X) has a Dell Part Number of VVR75 or 0VVR75, it has an LCD Part Number: XM5XG and a manufacturer P/N: N156B6 -L0B. The Letter N tells us that the manufacturer is CHI MEI and the 156 that this is a 15.6 inch screen.
