Ledman COB Ultra HD Curved Display
The Lab’s exhibition hall vertical screen and ceiling screen serve as the flagship displays. Equipped with Ledman COB Ultra HD Energy-saving Cold Screens, they enhance visitors’ immersive experience with 8K-level detail, showcasing Malanshan’s achievements in “integrating culture and technology.”
The curved Ledman COB Ultra HD display in the Lab’s lobby preface hall seamlessly conforms to the spatial structure. Also supporting 8K resolution, it vividly demonstrate the advancement and reliability of Ledman COB technology in delivering ultra-high-definition, multi-size, and specially shaped displays.
Ledman consistently focuses on Micro LED display R&D innovation based on COB integrated packaging technology, holding multiple proprietary core patents. Both sets of Ledman COB Ultra HD displays deployed at the Malanshan Audio-Video Lab embody COB technical characteristics. Notably, the curved screen achieves seamless splicing with no visible joints, delivering a high-definition, refined picture with comfortable and soft visual effects.
The vertical and ceiling screens further incorporate Ledman’s proprietary PSE Energy-saving Cold Screen technology. This screen boasts distinctive display traits: “Vibrant (rich colors), Cool (excellent thermal control), Crystal-clear (transparent image), Deep Black (profound contrast).” Compared to similar products, power consumption is significantly reduced by over 50%. The ultra-fine 0.7mm pixel pitch ensures smooth, detailed imagery, enabling the product to deliver stunning picture quality while supporting green, eco-friendly operation.
The client has provided highly positive feedback on Ledman’s products. Ledman’s prior installation of an extra-large COB Ultra HD Energy-saving Cold Screen within the Malanshan Video Cultural & Creative Industrial Park laid a solid foundation for this project collaboration. The outstanding visual performance, stable operation, and remarkable energy efficiency demonstrated in both projects confirm the high-standard compatibility of Ledman COB Ultra HD products for premium professional AV scenarios, also establishing a practical benchmark for the industry’s ultra-high-definition display solutions.
