Bezel / Seam

Understanding Bezels and Seams

Seamless appearance is a key quality indicator for LED walls. Understanding what causes visible seams helps with product selection and installation quality control.

What Creates Visible Seams

**Physical Gap:** Actual space between panels:

• Manufacturing tolerance
• Design limitation
• Typically 0-2mm

**Brightness Difference:** Edge pixels differ from center:

• Manufacturing variation
• Calibration issues
• Visible as light/dark lines

**Color Difference:** Edge pixels show different color:

• LED binning variation
• Calibration mismatch
• Visible as color bands

**Alignment Error:** Panels not perfectly aligned:

• Installation error
• Damaged quick-locks
• Floor/structure issues

Quality Specifications

**Premium Panels:**

• <0.5mm physical gap
• <3% brightness variation at seams
• Precision quick-lock mechanisms
• Tight manufacturing tolerances

**Standard Panels:**

• 0.5-1mm physical gap
• 5-10% brightness variation
• Acceptable for most applications
• Distance makes seams less visible

**Budget Panels:**

• >1mm physical gap
• Significant edge variation
• Best for distant viewing only
• May require post-processing

Seam Visibility Factors

**Content:**

• Solid colors show seams most
• Dark content hides seams
• Motion masks seams
• Graphics with lines affected

**Viewing Distance:**

• Close viewing reveals seams
• Distance masks seams
• Match quality to application

**Viewing Angle:**

• Off-angle viewing shows seams more
• Direct viewing minimizes
• Consider audience positions

Zero-Bezel Technology

**Common Surface Design:** Modules overlap cabinet edges:

• Pixels extend to very edge
• No frame visible
• Seamless appearance

**Precision Manufacturing:**

• Tighter tolerances
• Premium pricing
• Broadcast/VP applications

Installation Techniques

**Proper Alignment:** 1. Verify structure is flat/level 2. Use alignment guides/tools 3. Check each connection 4. View from critical distances

**Troubleshooting:**

• Inspect quick-lock mechanisms
• Check for debris in connections
• Verify structure flatness
• Consider recalibration

Calibration Solutions

**Edge Calibration:**

• Match brightness at seams
• Match color at seams
• Specialty calibration tools
• Professional service often needed

**Pixel-Level Correction:**

• Per-pixel brightness adjustment
• Masks manufacturing variance
• Requires calibration system

Application Requirements

**Broadcast/Virtual Production:**

• Zero-bezel essential
• Tight tolerances required
• Camera reveals imperfections
• Premium panels required

**Corporate/Events:**

• Near-zero acceptable
• View distance provides margin
• Good quality standard

**Outdoor/Distance:**

• Some seam acceptable
• Distance masks issues
• Budget considerations valid
