Frequently Asked Questions
COB (Chip-on-Board) is an advanced LED packaging technology where bare LED chips are directly mounted onto the PCB substrate. Our screens use Flip Chip COB, which eliminates traditional wire bonding, resulting in better thermal performance, higher reliability, wider color gamut, and superior image clarity compared to conventional SMD LED displays.
The COB poster screen is designed for indoor semi-outdoor environments. The front surface carries an IP54 rating (dust-proof and splash-proof, cleanable with wet cloth), making it suitable for covered storefronts, mall interiors, and lobby areas. For direct outdoor exposure, please consult our team for weatherproof alternatives.
The poster screen supports multiple connectivity options: USB, HDMI, Wi-Fi, PC, mobile phone, and iPad. It's true plug-and-play — connect your device and display content immediately. Built-in 2×5W stereo speakers provide audio without external equipment. No dedicated media player is required.
Yes. The COB poster screen supports seamless cascading splicing. Multiple units can be combined into 2K, 4K, or 8K large-format displays with zero visible gap between screens. This makes it ideal for conference halls, exhibition walls, and immersive brand experiences.
Flip Chip COB technology significantly extends LED lifespan by eliminating wire bond failure points. The operating temperature range is -20°C to +60°C with 10%~75% RH humidity tolerance. Please contact us for specific warranty terms based on your model and usage scenario.
We offer four standard models (P1.53, P1.56, P1.86, P1.875) and support custom configurations for cascading large-format displays. Contact our team with your specific requirements for a tailored solution.
