Waterproof COB Fine Pixel Pitch LED Displays 600 Nits Brightness High Contrast Ratio

• Front electrode blocks light, resulting in lower light emission efficiency
• Insulating adhesive used for die bonding leads to reduced heat dissipation
• Requires gold wire electrical connections, resulting in lower reliability
• Lower operating current and power capabilities

• Bottom-mounted electrodes don't block light, providing higher emission efficiency
• Metal electrodes enable superior heat dissipation
• Full-surface metal electrode connections ensure high reliability
• Operates efficiently at both low and high current levels

• Easy component transfer and rework capabilities
• Pixel-independent design

• Larger size limits ultra-fine pitch possibilities
• Requires secondary transfer, reducing efficiency
• Limited impact resistance and protection
• Additional processing steps increase costs

• Streamlined supply chain with significant cost reduction potential
• Excellent protection with waterproof and dustproof capabilities
• Enables ultra-fine and micro-pitch configurations

• Technology maturity continues to evolve

High brightness with low energy consumption - increases brightness by 20% or reduces consumption by 20% for superior heat dissipation and contrast.

Each panel includes dual backup power supplies and receiving cards. If one component fails, the backup ensures continuous panel operation.

No external cables between cabinets. Internal cable connections provide stable signal and power transmission with clean, streamlined appearance.
