5. Maintenance and Care

Proper care will extend the lifespan and maintain the performance of your Walfront 2.8in Display Monitor.

• Cleaning the Screen: Use a soft, lint-free cloth, slightly dampened with water or a screen-specific cleaning solution. Do not spray liquid directly onto the screen. Avoid harsh chemicals, abrasive cleaners, or solvents.
• Handling: Always handle the display by its edges. Avoid touching the flexible PCB connector with bare hands to prevent static discharge or contamination.
• Storage: When not in use, store the display in a dry, dust-free environment, away from direct sunlight and extreme temperatures. Keep it in its original packaging or an anti-static bag if possible.
• Environmental Conditions: Avoid exposing the display to excessive moisture, humidity, or extreme temperatures, as these can damage internal components.
• Physical Protection: Protect the screen from scratches and impacts. While the ABS material offers some resistance, direct force can still cause damage.

6. Troubleshooting

If you encounter issues with your display, refer to the following common problems and solutions:

• No Display/Blank Screen:
  • Check power supply: Ensure the display is receiving the correct voltage.
  • Verify connections: Confirm that the flexible PCB connector is securely and correctly attached to the host device.
  • Software configuration: Ensure display drivers are installed and the software is configured to output to the display.
• Incorrect Colors/Distorted Image:
  • Check data connections: Loose or incorrect data lines can cause display issues.
  • Resolution mismatch: Ensure your software's output resolution matches the display's native 240x320 resolution.
• Touch Screen Unresponsive:
  • Check touch controller connections: Verify that the touch interface pins are correctly connected.
  • Touch driver: Ensure the touch screen drivers are properly installed and initialized in your software.
  • Calibration: The touch screen may require calibration. Refer to your software's documentation for calibration procedures.
• Flickering Display:
  • Power supply instability: Ensure a stable power supply. Fluctuations can cause flickering.
  • Cable integrity: Check for damaged or loose cables.
