3. Setup Instructions
Before beginning installation, ensure all power is disconnected from your display panel and the driver board. It is highly recommended to consult customer service or verify the complete screen model clearly before connecting to ensure compatibility.
- Prepare Components: Unpack the EDP driver board, switch board, screen cable, and backlight cable.
- Connect EDP Panel: Carefully connect the screen cable (EDP cable) to the 30P EDP output interface on the driver board and to the corresponding input on your EDP LCD panel. Ensure correct orientation and secure connection.
- Connect Backlight: Attach the backlight cable from your LCD panel to the 'backlight' connector on the driver board (refer to Figure 2).
- Connect Control Buttons: Connect the switch board to the 'key' connector on the driver board. This board typically provides power, menu, and input selection controls.
- Connect HDMI Source: Connect your HDMI input device (e.g., computer, media player) to the 'HDMI input' port on the driver board.
- Connect Audio Output (Optional): If external audio is desired, connect speakers or headphones to the 'Audio output' port.
- Apply Power: Connect a 12V DC power supply to the '12V power input' port on the driver board. Ensure the power supply meets the board's specifications.
- Initial Power On: Power on the display panel and then the driver board. The display should show the input from the HDMI source.
4. Operating Instructions
Once the driver board is correctly installed and powered, operation is straightforward.
- Power On/Off: Use the power button on the connected switch board to turn the display on or off.
- Input Selection: If multiple inputs are supported (e.g., via the switch board), use the designated buttons to cycle through available video sources.
- Resolution Adaptation: The board supports various resolutions, automatically adapting to the connected EDP panel and HDMI input. It optimizes image quality, enhancing color, contrast, and detail.
- Menu Navigation: If the switch board includes menu buttons, you can access and adjust display settings such as brightness, contrast, and color balance. Refer to the specific switch board's documentation for detailed menu options.
5. Maintenance
Proper maintenance ensures the longevity and reliable performance of your EDP LCD Driver Board.

- Confirm the LCD panel is compatible with the driver board's output specifications (e.g., 1366x768 resolution).
- Incorrect Resolution or Distorted Image:
- Ensure the HDMI source is set to an output resolution compatible with the EDP panel and driver board.
- Restart the system (power off and on) to allow the board to re-detect the panel.
- No Audio:
- Verify that the audio output cable is correctly connected to external speakers or headphones.
- Check the audio settings on your HDMI source device.
- Buttons Not Responding:
- Ensure the switch board is properly connected to the 'key' connector on the driver board.
