How to choose the right product for small pitch LED display and LCD video wall?

1. Total Budget Considerations

The cost difference between LED displays and LCD video walls is significant.

LED Displays: The price depends on the pixel pitch. A smaller pixel pitch increases the cost dramatically. For example:

• P3 LED: several thousand dollars per square meter
• P1.5 LED: approximately $4,700 per square meter

LCD Video Walls (Qtenboard Example): Price is calculated based on panel size and bezel width. For instance:

• 55-inch panels with a 3.5mm bezel: moderate cost
• 0.88mm bezel: ~30% higher

Overall, LCD video walls tend to offer better cost-performance, especially for indoor, close-range applications.

2. Sight Distance and Resolution Requirements

LED Displays: Best suited for long-distance viewing. At close range, pixelation may occur due to lower pixel density.

LCD Video Walls: Designed for near- and mid-range viewing. Each panel typically supports Full HD (1920×1080), and multi-panel configurations can achieve 4K resolution or higher without loss of clarity.

Qtenboard Advantage: LCD panels maintain consistent image sharpness and color fidelity across multi-screen setups, ensuring a near-seamless viewing experience.

3. Display Performance

LCD Video Wall Advantages:

• High Definition: Full HD or 4K content with multi-panel splicing.
• Appropriate Brightness: Comfortable for long-term indoor viewing without glare.
• High Contrast and Color Accuracy: Smooth, delicate imagery with accurate color reproduction.
• Multi-Signal Support: Can simultaneously display multiple computer inputs, ideal for control rooms and conference rooms.
• Durable & Reliable: Industrial-grade panels with 50,000+ hours of lifespan, supporting 24/7 operation.

LED Display Advantages:

• Seamless Splicing: Minimal visual interruptions for large-scale displays.
• High Brightness with Auto Adjustment: Maintains comfortable viewing in varying lighting conditions.
• High Gray Scale and Color Accuracy: Details remain clear even at low brightness.
• Fast Response and High Refresh Rate: Smooth motion display without flicker.
• 3D Visual Capability: Immersive experiences for exhibitions, events, or advertising.

4. Application Scenarios

For monitoring rooms, small/medium meeting rooms, or exhibition halls, LCD video walls are often more suitable due to superior color, sharpness, and signal decoding capabilities. LED displays are ideal for large-format visuals in public or press settings, where brightness and seamless appearance are key.

5. Advantages & Limitations

LCD Video Wall:

Advantages:

• High resolution (1920×1080 per panel, 4K spliced possible)
• Comfortable brightness for long-term viewing
• High contrast and accurate color
• Multi-signal display capabilities
• Long service life, low maintenance
• Ultra-narrow bezels (0.88mm, 1.7mm, 3.5mm)

Limitations:

• Bezel creates slight seams (though modern ultra-narrow bezels minimize this)
• Indoor use only (not waterproof)

LED Display:

Advantages:

• Seamless visual experience
• Adjustable brightness for varying environments
• High gray scale and color fidelity
• Fast response, high refresh rates, 3D capability

Limitations:

• Pixel loss due to unavoidable unit seams
• Viewing angle limited (~140°)
• Too high brightness indoors can cause eye strain
• Small-pitch LED is expensive
• Standard cabinet size may limit resolution
