Six Key Considerations for LCD Splicing Screen Installation and Maintenance

1. Installation Ground Selection

The foundation is the first factor to consider. LCD splicing screens require a stable, flat, and anti-static floor. Due to the size and weight of large-scale video walls—such as a 3×3 array of 55-inch panels weighing over 250 kg—the floor must be capable of supporting this load without warping or settling.

Key Requirements:

• Floor must be structurally reinforced if using tiles or non-industrial flooring.
• Anti-static flooring prevents panel damage from electrostatic discharge.
• Level tolerance should not exceed ±2mm over the full installation area to avoid panel misalignment.

Qtenboard Case: Our recent installation of a 4×4 55-inch 1.8mm bezel LCD video wall for a Malaysia command center was preceded by a floor load test to ensure stability. The wall was installed without any structural reinforcement issues, completing the installation in 10 days from delivery to calibration.

2. Wiring Configuration and Signal Management

Large LCD video walls integrate multiple panels, each requiring precise power and signal routing. Improper wiring can lead to flickering, signal loss, or even component damage.

Best Practices:

• Separate power lines from signal lines to prevent electromagnetic interference.
• Use high-quality shielded HDMI, DP, or SDI cables appropriate for the panel resolution (FHD, 4K).
• Pre-calculate cable lengths according to panel arrangement and distance to media sources.
• Implement cable management channels to allow easy maintenance and future upgrades.

Professional Tip: Multi-source setups, common in monitoring rooms or exhibition halls, require dedicated distribution matrices or video wall controllers to handle multiple input signals without losing resolution or color fidelity.

3. Ambient Light Control

While LCD screens provide high brightness, excessive ambient light reduces visibility and can cause glare.

Guidelines:

• Avoid direct sunlight or strong artificial light on panels.
• Utilize blinds or anti-reflective coatings on nearby windows.
• Use indirect lighting (downlights) instead of front-facing lights.
• For rooms with variable lighting conditions, integrate adaptive brightness controls to maintain optimal visibility.

Qtenboard Insight: During our installation in a Singapore corporate boardroom, ambient light analysis allowed us to adjust lighting to reduce reflection on a 3×3 55-inch 3.5mm LCD wall, resulting in a 30% improvement in perceived contrast during daytime operation.

4. Frame and Maintenance Accessibility

Proper framing is essential to facilitate long-term service and maintenance:

• Panels should have detachable side trims for easy access.
• Reserve a 25mm margin between the frame and the panel edges, and expand proportionally for larger video walls.
• Maintenance channels should be at least 1.2 meters wide to allow technicians to access the rear without removing panels.
• Detachable strips should be secured after panels and cabinets are fully installed to avoid misalignment.

Qtenboard Note: For large-scale installations like 4×5 video walls in control rooms, these maintenance allowances prevent downtime and simplify panel replacement or backlight servicing.

5. Ventilation and Thermal Management

Heat accumulation is one of the biggest threats to panel lifespan. LCD splicing screens generate heat that must be properly dissipated.

Recommendations:

• Ensure smooth airflow behind and around the video wall.
• Position air outlets at least 1 meter away and avoid blowing directly on panels.
• For large installations, use dedicated cooling systems and temperature monitoring to maintain consistent operation between 18–25°C.

Qtenboard Experience: Our 3×4 55-inch video wall installed in a Malaysia control room includes precision airflow calculations, maintaining panel temperature under 28°C after continuous 24/7 operation for over six months.

6. Professional Installation and Long-Term Maintenance

Even with careful planning, professional installation is crucial to prevent damage and ensure longevity:

• Trained technicians handle panel alignment, calibration, and signal configuration.
• Preventive maintenance is required periodically: clean panels, reset colors, check connections, and inspect cabling.
• For multi-computer or multi-signal setups, professional guidance ensures accurate matrix switching and resolution management.

Qtenboard Case: Our 3×4 55-inch 1.8mm bezel installation in a Singapore exhibition hall required simultaneous display of five different signal sources, which was fully implemented and tested by our engineers, ensuring high-definition, seamless performance from day one.
