Have you ever wondered what to do with an old desktop LCD monitor or a laptop screen that's gathering dust? Instead of throwing it away, you can repurpose it into a portable display! This comprehensive guide will walk you through every step required to convert a desktop LCD into a portable monitor. Whether you want a second screen for your laptop, a display for your Raspberry Pi, or a portable gaming monitor, this DIY project is not only cost-effective but also environmentally friendly.
Before you begin, gather the following tools and materials:
- Old desktop or laptop LCD screen
- Compatible LCD controller board (HDMI/USB-C/VGA input, matched to your LCD model)
- Power adapter (usually 12V, check your controller board specs)
- Screwdrivers (Phillips and flathead)
- Electrical tape or heat shrink tubing
- Enclosure materials (MDF, acrylic, 3D-printed, or repurposed frame)
- HDMI/USB-C cable
- Optional: Battery pack, stand, touch panel, speakers
Carefully unscrew the back panel of your monitor or laptop. Disconnect the LVDS cable and inverter from the screen. Remove the LCD panel, keeping the front frame and backing if possible for later use.
Look for a sticker at the back of the LCD with the model number (e.g., LTN156AT05). Write this down; you'll need it to order the correct controller board.
Use the model number to find a controller board online (search “LCD controller board [model number]”). Make sure the board supports your preferred input (HDMI, VGA, USB-C).
Most kits include the controller, LVDS cable, inverter (for CCFL backlights), and button board. Double-check compatibility before purchasing.
Plug the new LVDS cable from the controller board into the LCD panel. Secure the connection with tape if necessary.
Connect the inverter to the LCD and controller board. For LED screens, this step may not be necessary.
Attach the button board to the controller for power and menu controls.
Plug in the 12V adapter to the controller board.
Use HDMI, VGA, or USB-C to connect your device to the controller board.
Use MDF, acrylic, or 3D-printed parts to create a custom case. Repurpose the original monitor/laptop frame or use a picture frame for a simple solution.
Ensure ventilation for heat dissipation. Mount the controller board securely, avoiding contact with metal surfaces to prevent shorts.
Attach a tripod mount or folding stand for portability.
Use the supplied AC adapter for stationary use. For true portability, connect a compatible battery pack (e.g., 12V lithium battery).
Plug the monitor into laptops, PCs, game consoles, or Raspberry Pi using HDMI, VGA, or USB-C. Some controller boards support multiple inputs.
- Touchscreen Functionality: Add a compatible touch panel and controller for interactive use.
- Speakers: Install small speakers or use the audio output on the controller board.
- Battery Integration: For complete portability, integrate a rechargeable battery and charging circuit.
- Protective Case: Use a padded sleeve or hard case for transport.
Power up the monitor and connect to your device. The display should be detected automatically; adjust settings as needed.
- On Windows: Right-click desktop > Display settings > Arrange and extend displays.
- On macOS: System Preferences > Displays > Arrangement > Uncheck “Mirror Displays”.
Use built-in OS tools to calibrate the touch panel for accuracy.
Transforming a desktop LCD or laptop screen into a portable monitor is a practical and satisfying project that breathes new life into old hardware. With a modest investment in a controller board and some DIY effort, you can create a versatile, portable display for work, entertainment, or travel. This project not only saves money but also reduces electronic waste, making it a win-win for you and the environment.
A portable monitor is a lightweight, secondary display that connects to laptops, PCs, or mobile devices, providing extra screen space for multitasking, gaming, or presentations. Building your own is cost-effective and customizable.
Check the model number on the back of your LCD panel, then search online for a controller board compatible with that model (e.g., “LCD controller board LTN156AT05”).
Yes, you can add a compatible touch panel and controller. Ensure your controller board supports touch input and follow the manufacturer's instructions for installation and calibration.
You can connect laptops, desktops, Raspberry Pi, game consoles, smartphones (with USB-C video out), and more, depending on the inputs supported by your controller board (HDMI, VGA, USB-C).
Use a 12V battery pack or power bank with the correct voltage and current rating. Some advanced builds integrate rechargeable batteries with charging circuits for true portability.
