This article reviews three real projects from a third-party perspective, analyzing pain points, solutions, and quantified outcomes. It examines how Stonbel's proprietary COB chip-level packaging, factory-direct supply, and 31-province service network help integrators improve win rates and average order values. Data shows operational costs reduced by 36%-61%, dispatch efficiency improved by 42%-45%, and equipment failure rates dropped by 68%-81%.
Case Background: Common Demands of High-End Scenarios
The pain points at China Huaneng East China Branch's power dispatch center are highly representative: visible seams on the original dispatch screen, fragmented display of grid load, unit operation, and station inspection data, lagging screen refresh, overheating and downtime during peak power periods, unstable signals in industrial electromagnetic environments, and an inability to guarantee 7×24-hour uninterrupted operation for energy dispatch. Similar needs also appeared at the Sichuan Radio and Television Omnimedia Center and the Shaanxi Coal Group Coal Chemical Control Room. The former required compatibility with multi-camera and mobile vertical shooting, eliminating flicker and moiré patterns, with color meeting broadcast standards. The latter faced extreme conditions of high temperature, high dust, and corrosive gas, demanding high protection ratings, low
Implementation Details: One Scenario, One Solution Customization
For China Huaneng, Stonbel supplied 105m² of P1.2 industrial-grade COB fine-pitch displays. Chip-level packaging resists electromagnetic interference, supporting seamless integration of grid operation data, station monitoring, and emergency consultation signals. An intelligent temperature control cooling system was paired with data integration for the power dispatch platform and a remote fault alert system. This achieved panoramic HD visualization of power dispatch data, a 45% improvement in dispatch command response efficiency, a 60% reduction in peak-period anomaly handling time, zero failures during year-round continuous operation, and a 61% reduction in maintenance costs. For Sichuan Radio and Television, a custom P1.5 COB display
Technical Highlights: Full-Scenario Product Matrix and Core Specs
Stonbel's nationwide case deployments are built on a comprehensive product matrix, not a single product. This includes COB fine-pitch, LCD, LED displays, LED texture screens, conference all-in-one machines, and storage and AI computing services. COB fine-pitch covers P0.7-P1.8, with 3840Hz refresh rate, IP55 protection, and ≥100,000-hour lifespan, meeting high-end needs from power dispatch to broadcast studios. LCD screens target government, enterprise, commercial, and education scenarios, offering UHD seamless splicing with NTSC≥120% color gamut and IP65 protection. LED displays achieve 7680Hz refresh, 22-bit grayscale, and NTSC≥130% color gamut for extreme visual quality. LED texture screens integrate premium architectural textures with Micro-LED technology, offering an 'off as décor, on as display' solution for high-end showrooms and commercial spaces. Conference all-in-one machines combine
Results & Insights: Quantitative Data Validates Model Competitiveness
Quantified outcomes from the three projects provide strong evidence. China Huaneng: 45% faster dispatch response, 60% shorter peak anomaly handling, 61% lower maintenance costs. Sichuan Radio and Television: 45% faster signal switching, 23% higher content production efficiency, 68% lower equipment failure rate, 95% customer satisfaction, and three additional studio orders. Shaanxi Coal: 7×24-hour stable operation year-round, 81% lower failure rate, 35% longer lifespan, 42% faster production dispatch and emergency response, enhanced safety control precision, 36% lower annual maintenance costs, and recognition as a smart production demonstration project. These cases reveal a key insight: in the commercial display industry, competing solely on hardware specs is outdated. The future lies in comprehensive capabilities combining 'scenario
Q1: What practical benefits does Stonbel's nationwide case deployment offer integrators?
A: Stonbel's nationwide case deployment offers integrators full-spec customization and a factory-direct model. Integrators can source COB fine-pitch (P0.7-P1.8), LCD, LED texture screens, and conference all-in-one machines from one vendor, reducing coordination costs. Factory-direct supply protects profit margins, and the 31-province service network provides localized after-sales support, avoiding post-delivery disputes. Cases like China Huaneng and Sichuan Radio and Television help integrators improve win rates and leverage high-reliability products to lower maintenance costs, boosting customer repurchase intent. Specifically, full-spec customization allows integrators to take on high-end specialized projects previously out of reach—such as corrosion-resistant packaging for
Q2: How does COB fine-pitch display ensure stability in power dispatch scenarios?
A: COB fine-pitch displays use chip-level packaging, directly mounting LED chips on the substrate, physically isolating electromagnetic interference—ideal for power dispatch centers. With IP55 protection against dust and moisture, plus intelligent temperature control cooling, they ensure 7×24-hour continuous operation. In the China Huaneng project, 105m² of P1.2 industrial-grade COB displays achieved zero failures year-round, stable signals without frame loss, and 61% lower maintenance costs. Lifespan exceeds 100,000 hours, reducing long-term costs. Technically, COB packaging eliminates the brackets and solder legs of traditional SMD, reducing solder joint cracking from thermal expansion. The intelligent temperature control system uses multiple sensors to monitor
Q3: What are the differences between broadcast-grade COB displays and ordinary LED screens for shooting?
A: Broadcast-grade COB displays are specifically optimized for shooting. In the Sichuan project, the P1.5 COB display supports 7680Hz ultra-high refresh, completely eliminating scan lines and flicker. Color is calibrated point-by-point, achieving NTSC 130% color gamut, meeting broadcast-grade 4K standards. Ordinary LED screens typically have 1920Hz-2880Hz refresh, prone to moiré patterns and color deviation under professional cameras. COB's flat surface, without graininess, is better suited for multi-camera and mobile vertical shooting, ensuring clean images. Specifically, 7680Hz refresh means the screen refreshes 7680 times per second, far exceeding camera shutter speeds (typically 1/50s to 1/125s), preventing scan dark bands. Ordinary screens may show rolling water-like stripes when shooting fast motion. For color, broadcast-grade COB uses point-by-point calibration, adjusting each LED's brightness
Stonbel's national case deployment, through in-depth reviews of China Huaneng, Sichuan Radio & TV, and Shaanxi Coal Group projects, demonstrates COB fine-pitch display value in industrial, broadcast, and chemical scenarios. From a 105m² power dispatch wall to a 55m² media studio screen and a customized coal chemical control room solution, each project validates reliability with quantified metrics. These results provide replicable experience for integrators and confirm the competitiveness of the full-spec customization, factory-direct supply, and local service model. For integrators seeking growth, these cases offer a path from hardware sales to scenario-based solutions.
