1. First, ensure your monitor panel size matches. You can check on screenlogging websites. Because new panels are thinner now, and older large-screen laptops are less common, and the mainstream aspect ratio has changed, finding a matching size is generally difficult.
It's best to choose a panel with multiple backlight tubes, as backlight tubes have a lifespan and can burn out, while CCFL panels are mostly old stock or salvaged parts. Of the several I tested, LG was the most eye-friendly; Samsung was the worst, too bright and glaring, so I don't recommend Samsung.
2. Find the corresponding panel model on Taobao and order a complete set (including CCFL monitor panel, screen cable, driver board, high-voltage strip (CCFL tubes require 2000V), control board, and power supply). This set can be directly encased to create an external monitor.
To clarify, LED monitors don't need a high-voltage strip; current laptop screen cables use EDP interfaces, while most CCFLs use LVDS interfaces, so a separate driver board is needed. Connect the laptop and driver board with a video cable. For power, you can use a separate power supply to the driver board, or you can run a 12V 2-pin male/female connector from the laptop to the driver board. 3. Integrate the purchased set into the laptop.
The main difficulty lies in changing the signal interface, which requires adding a lot of components. It takes considerable expertise to miniaturize and integrate these into the laptop; most people can't do it, and forcing it will only result in a bulge on the A-side. Of course, if the signal interface remains unchanged, then simply replacing it is sufficient.
