පුංචි LED දර්ශනය සහ LCD වීඩියෝ බිත්තිය සඳහා නිවැරදි තෝරගන්නේ කොහොමද?

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 වීඩියෝ තාර: 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 අදහස

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:

ප් රයෝජන:

• 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:

ප් රයෝජන:

• 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
