Product Highlights
Say Goodbye to Tradition. Experience a Leap in Image Quality
Traditional SMD (Surface Mount) LED displays face growing demands for image quality and durability. COB technology directly encapsulates LED chips onto the circuit board, forming a uniform protective layer that creates a flatter, more robust and reliable screen for professional environments.
Every Detail Designed to Deliver Superb User Experience
Choose P0.78–P1.86 for clear engineering drawings, financial statements or live broadcasts. Flip-chip COB improves heat dissipation, lowers failure rates, saves energy and extends lifespan. The 170° viewing angle keeps brightness and color consistent from center or side. Fanless operation is silent. Front-removable modules, power supply and receiver card simplify wall-mounted maintenance without removing the back panel.
Superior Surface Protection
COB’s integrated protective layer withstands daily bumps, knocks and environmental influences better than traditional LED chips. It is dustproof, waterproof, anti-static, impact-resistant and easy to clean, making it suitable for high-traffic public spaces, conference rooms and exhibition halls where people walk and touch the surface.
Superior Heat Dissipation & Extended Lifespan
Excellent heat dissipation extends service life, reducing the need for frequent maintenance and replacements while helping keep your investment valuable for an extended period.
Dual-path Protection. Double the Peace of Mind
COB screens support dual-redundancy backup with dual power supplies and dual signals through dual network port loops. The power supplies provide current-sharing backup; if one fails, the other takes over seamlessly for uninterrupted power. Primary and backup signals synchronize in real time and switch automatically in milliseconds, eliminating screen paralysis caused by signal interruptions.
Less Trouble, More Savings
COB’s high reliability reduces daily maintenance and failure rates, lowering overall costs across the display’s lifespan. Considering long-term costs as well as initial visual quality makes the display more worry-free to use.
