SMD vs COB vs MIP: Key Differences in LED Video Wall Tech

The LED video wall industry is evolving rapidly, with SMD, COB, and MIP being the most discussed packaging technologies. Each has unique advantages in terms of pixel pitch, durability, brightness, and application scenarios. Understanding these differences is crucial for making informed decisions in control rooms, retail, hospitality, and large-scale events.

What is SMD LED Technology?

Surface-Mounted Device (SMD) is the most widely used packaging method in LED video walls.(TQM-LED Display)

• Advantages: Mature technology, cost-effective, versatile.
• Applications: Indoor/outdoor LED screens, rental displays, stadiums.
• Limitations: Limited pixel pitch for ultra-fine displays, risk of LED damage due to exposed diodes.

What is COB LED Technology?

Chip on Board (COB) directly packages LED chips onto the PCB.(TQW – Series Micro COB LED)

• Advantages: High durability, anti-collision surface, dustproof, waterproof, better heat dissipation.
• Applications: Control rooms, high-end conference displays, fine-pitch LED video walls.
• Limitations: Higher production cost, more complex repair process.

What is MIP LED Technology?

Mini LED in Package (MIP) is the latest packaging trend, offering modular flexibility and scalability.

• Advantages: Improved uniformity, better yield rates, future-proof for Micro LED transition.
• Applications: Premium consumer electronics, fine-pitch indoor displays, emerging high-resolution markets.
• Limitations: New technology, limited large-scale adoption so far, relatively high initial cost.
