As the ultra-high-definition video industry accelerates into the 4K/8K era, LED display technology is undergoing a rapid iteration from traditional SMD to COB packaging. Boasting seamless splicing, high reliability and excellent protection performance, COB has achieved a penetration rate of over 85% in the high-end fine-pitch market below P1.4. The continuous decline in cost thresholds has further made it a core driving force for the popularization of ultra-high-definition large screens. Amid this technological wave, HKC keeps forging ahead with innovations. The newly launched COB products feature a minimum pixel pitch of 0.7mm, accompanied by the release of the P1.5 foldable LED solution. This further consolidates HKC’s technological depth in the high-end conference and professional commercial display markets, meeting customers’ differentiated demands for display precision and deployment efficiency across diverse scenarios.
Independent Core Technology: Self-developed Flip-Chip COB and High Blackening Packaging
All new HKC COB products adopt self-developed full flip-chip COB chips and integrated high blackening packaging technology in process design. Different from traditional SMD or formal packaging processes, HKC’s full flip-chip structural solution eliminates gold wire connection. It not only greatly improves product reliability, but also delivers outstanding heat dissipation and high energy efficiency.
The integrated high blackening packaging process applies high-blackening treatment to the lamp board surface, effectively reducing panel reflectivity. The display presents excellent black uniformity when powered off, and delivers an ultra-high contrast ratio of 10000:1 with purer and deeper image quality when powered on.
Ultimate Image Quality & Industrial Design: An Integrated Audio-visual Feast of Hardware and Software
Based on the hardware foundation of high-density pixel arrangement, HKC COB products adopt AI intelligent image quality enhancement algorithms, which can easily decode and render 4K and even 8K ultra-high-definition images, significantly enhancing image details and viewing experience. While achieving key display performance indicators, it creates ultimate visual effects through hardware and software coordination:
High Refresh Rate: It supports an ultra-high refresh rate of 3840Hz, ensuring dynamic images free of ghosting and tearing, especially suitable for studio environments with high-speed camera shooting.
Superior Uniformity: The brightness uniformity reaches over 98%, avoiding uneven color and brightness patches and maintaining highly consistent color and brightness for large-size screens.
In terms of structural design, the cabinet adopts die-cast aluminum alloy material, which ensures structural strength while keeping the single cabinet weight as low as 2.1kg, greatly lowering the load-bearing requirement for installation walls. With an ultra-slim cabinet thickness of 32mm and CNC precision processing technology, it adapts to complex installation conditions and achieves flatness accuracy within 0.1mm, laying a solid structural foundation for subsequent modular expansion, electromagnetic shielding and other functional upgrades.
In addition, for application scenarios requiring flexible deployment and frequent movement, HKC P1.5 foldable LED products adopt an integrated design of display panel and foldable supporting base. The panel and base are connected via a hinge structure while maintaining an all-in-one integrated design. Users can unfold it for immediate use without on-site assembly; when folded, its volume is greatly reduced for easy storage, transportation and reinstallation, balancing portability and greatly improving installation efficiency.
High Reliability & Low Maintenance Cost, Adaptable to Complex Operating Environments
Targeting the long-term operational stability and maintenance pain points of commercial scenarios, HKC COB products adopt an integrated sealed protection design, providing all-round performance of dustproof, moistureproof, collision-proof and aging resistance. It adapts to various complex environments and ensures stable 7×24-hour continuous operation, greatly reducing the full-lifecycle maintenance cost and meeting long-term application demands in command centers, medical diagnosis, commercial exhibitions and other fields.
Meanwhile, compared with traditional spliced large-screen solutions, the cost advantage of this product series is expected to further lower the application threshold of ultra-high-definition large screens. It accelerates market implementation in government and enterprise conferences, command and dispatch, high-end retail, home theaters and other scenarios, driving the popularization and upgrading of the ultra-high-definition display industry.
From small screens to large screens, and from LCD to in-depth application of Mini LED, OLED and MicroLED technologies, HKC continues to expand the boundary of display technology application. The newly launched COB ultra-high-definition display products, featuring superior performance, high convenience and cost performance, will drive COB technology from mainstream adoption to comprehensive popularization, and deliver innovative display solutions for all industries.
