• Design: Multiple LED chips are bonded directly to a substrate, encapsulated under a unified phosphor coating.

• Advantages:

  - Higher pixel density (ideal for close-viewing scenarios).

  - Superior heat dissipation due to direct PCB contact.

  - Dust/water resistance (no exposed solder joints).

• BRWall Use Cases: Control rooms, high-end retail, and fine-pitch indoor installations.

• Design: Individual LEDs are mounted on the surface of PCBs, with separate red, green, and blue diodes.

• Advantages:

  - Cost-effective manufacturing.

  - Flexible pixel pitches for diverse resolutions.

  - Easier maintenance (replaceable modules). .

• BRWall Use Cases: Large-format outdoor billboards, stadium screens, and rental staging.

• COB excels in environments requiring precision and reliability (e.g., medical imaging, broadcast studios).

• SMD dominates high-brightness, large-scale projects (e.g., highway signage, concert screens).

• Museums/Galleries: True-to-life color reproduction for digital art displays.

• Corporate Lobbies: Seamless ultra-HD video walls for brand storytelling.

• Sports Arenas: Weather-resistant displays with wide visibility under sunlight.

• Retail Facades: Eye-catching promotions with vibrant colors.

• COB: Higher upfront cost but lower maintenance (20% fewer failures vs. SMD).

• SMD: Budget-friendly for large deployments; ideal for temporary installations.

BRWall is investing in COB-SMD hybrid panels to merge COB’s durability with SMD’s brightness, targeting smart cities and immersive XR experiences.

Choosing between COB and SMD depends on your project’s scale, environment, and budget. For mission-critical precision, BRWall’s COB solutions deliver unmatched reliability. For large-scale impact, SMD remains the cost-effective workhorse.
