Curved LED Display

Understanding Curved LED Displays

Curved LED configurations enable creative visual designs beyond flat walls. Understanding the mechanics and limitations of curved displays helps achieve successful implementations.

Curve Mechanics

**Adjustable Connections:** Most LED panels feature adjustable locking mechanisms:

• Standard range: ±5° to ±15°
• Adjusted at cabinet connection points
• Same panel, different configurations

**Curve Radius Calculation:** Radius = Panel width ÷ (2 × sin(angle/2))

**Example (500mm panel, 10° angle):** R = 500 ÷ (2 × sin(5°)) = 500 ÷ 0.174 = 2,873mm (≈2.9m)

Types of Curves

**Concave:** Curves toward viewer:

• Wraps around audience
• Immersive experience
• Common for stages, control rooms
• Content appears to surround viewer

**Convex:** Curves away from viewer:

• Wraps around structure
• Column wraps, 360° displays
• Viewers walk around display
• Content visible from multiple angles

**Compound Curves:** Combination of directions:

• Wave patterns
• Creative installations
• Requires careful planning
• More complex content mapping

Panel Requirements

**Standard Panels:**

• Limited angle range
• Gaps visible at extreme angles
• Suitable for gentle curves
• Most cost-effective

**Flexible/Soft LED:**

• Bendable substrate
• Smooth curves without gaps
• More delicate
• Higher cost

**Purpose-Built Curved:**

• Fixed curve angle
• Seamless appearance
• Limited flexibility
• Premium pricing

Design Considerations

**Minimum Radius:** Determines how tight a curve is possible:

• Smaller panels = tighter curves
• More panels = smoother appearance
• Budget vs. curve requirement trade-off

**Content Mapping:** Curved surfaces require:

• Perspective correction
• Warping software
• Edge blending (for some)
• Testing with actual content

**Viewing Position:** Curve direction affects viewing:

• Concave: Best from center
• Convex: Multiple viewing positions
• Consider primary audience location

Structural Requirements

**Curved Ground Support:** Must match LED curve:

• Custom curved base
• Adjustable structures
• Proper weight distribution

**Flying Curved Walls:** Additional considerations:

• Bridle point locations
• Load distribution on curve
• Trim angle effects

Common Applications

**Stage Backdrops:** Gentle concave curves add depth and wrap.

**Column Wraps:** Convex curves around structural columns.

**Circular/360° Displays:** Full convex circles for central installations.

**Creative Installations:** Waves, folds, and sculptural shapes.

Best Practices

**Prototype:** Test curve configuration before full deployment.

**Content Preview:** View content on actual curve, not flat preview.

**Documentation:** Record angle settings for future reference.

**Spares:** Curved configurations may stress panels—have spares ready.
