This review examines the Sinopec East China Branch Smart Exhibition Hall project, covering pain point identification, solution implementation, and data outcomes. It demonstrates the effectiveness of COB fine-pitch display technology and highlights how the certification system shortens delivery cycles and reduces maintenance costs. Through a third-party perspective, we show how standardized services convert technical parameters into business value and how this system replicates success across scenarios.
Case Background
Sinopec East China Branch faced significant limitations with traditional display solutions during its digital upgrade for brand showcasing and internal training. The initially planned projection tiling solution revealed issues in field tests, including blurred images and visible seams. This was particularly problematic when displaying production data visualizations, where latency and stuttering during real-time multi-source switching directly impacted presentations. Compounding this, the project required coordination among hardware suppliers, system integrators, and maintenance providers, leading to high communication costs, unclear responsibilities, and a projected delivery timeline of 45 days. This scenario is common in government and enterprise exhibition halls: when display
Implementation Details
Stonbel's certified service network demonstrated end-to-end control from site survey to maintenance. The technical team first conducted an on-site survey, determining that a 120-inch P1.5 COB fine-pitch LED display was optimal based on viewing distance and ambient lighting. This pixel pitch delivers fine image quality at a 3-meter viewing distance and meets the physical pixel requirements for 4K content. The proprietary multi-screen controller supports 12 signal inputs, simultaneously connecting corporate videos, production dashboards, and training materials, with one-click switching between preset scenes via video processing software. During installation, certified engineers followed standardized procedures for cabinet assembly and system debugging, consolidating hardware procurement,
Technical Highlights
The core technical highlights center on the synergy between COB chip-level packaging and the certified service network. COB packaging directly mounts light-emitting chips onto the PCB, eliminating the brackets and solder feet of traditional SMD processes. This enables a P1.5 pixel pitch display with higher contrast, more uniform brightness, and a seamless picture without graininess even at close range. Test data shows an 80% improvement in clarity over the original projection solution, with a 3840Hz refresh rate that eliminates scan lines in photography or live streaming. Crucially, Stonbel's certified service network translates these technical parameters into service standards: certified engineers must pass theoretical and practical exams to ensure installation precision and calibration meet factory specifications. This integration of technical capability and service processes directly reduces failure rates—the display boasts a lifespan of over 100,000 hours, an IP55 protection rating for dust and splash resistance, and 42% lower three-year
Outcomes & Insights
Operational data post-launch validates the value of Stonbel's certified service network. Since deployment, Sinopec East China Branch's visitor reception efficiency has increased by 65%—visitors can quickly grasp corporate overviews and production processes via the large screen without device switching. Internal employee training coverage has risen by 70%, with multi-source switching enabling simultaneous display of training materials, demonstrations, and real-time data for enhanced interactivity. The key insight for the industry is that success in commercial display projects depends not only on hardware specs but also on the delivery quality and maintenance responsiveness guaranteed by a certified service network. For integrators, this system reduces multi-vendor coordination costs, compressing project cycles from 45 to 22 days, leading to higher
Q1: What specific services does the Stonbel certified service network include?
A: The Stonbel certified service network covers the entire process from project survey, solution design, equipment installation, system commissioning, to maintenance training. Certified engineers must pass theoretical and practical exams, with service points in 31 provinces for rapid response. Services include site survey (assessing viewing distance, ambient light, wall load), multi-screen controller configuration (supporting 12+ signal inputs), video processing software debugging (preset scene switching, multi-window layouts), operator training (standardized manuals and on-site guidance), and ongoing maintenance (regular inspections, spare parts replacement, remote diagnostics). All steps follow standardized procedures to ensure delivery quality and fault handling efficiency. For example, engineers use professional
Q2: What advantages does COB fine-pitch LED offer over traditional projection in exhibition halls?
A: COB fine-pitch LED uses chip-level packaging with pixel pitch down to P1.5, delivering a seamless picture with 80% higher clarity than projection and a 3840Hz refresh rate without scan lines. Its brightness and contrast are unaffected by ambient light, making it ideal for bright environments like exhibition halls, with vivid colors even under strong lighting. With a lifespan exceeding 100,000 hours and IP55 protection, maintenance costs are low, avoiding frequent projector lamp replacements. In smart exhibition projects, it supports real-time multi-source switching and 4K ultra-HD display, meeting needs for corporate promotion, data visualization, and training. COB's high contrast (up to 10000:1) ensures purer blacks and brighter
Q3: How should long-term maintenance costs for commercial display projects be evaluated?
A: Long-term maintenance costs mainly include energy consumption, spare parts replacement, fault repair, and manual inspections. In the Sinopec project, adopting Stonbel's certified service network reduced three-year maintenance costs by 42% compared to traditional solutions, thanks to the modular COB display design allowing quick single-point replacement and standardized repair processes that shorten recovery time. Key metrics to consider: product lifespan (≥100,000 hours) directly impacts replacement cycles; protection rating (IP55) determines tolerance to dust and moisture, reducing environment-related faults; refresh rate (3840Hz) affects visual experience, with higher rates reducing eye strain and complaints; service response time (e.g., 2-hour emergency) quantifies downtime losses. Energy costs can be compared
Stonbel's Service Network Certification System proves the potential of combining standardized services with technological innovation. From the Sinopec project's 51% shorter delivery time and 42% lower maintenance costs to successful replication in government and cultural tourism projects, each metric reinforces the system's core value: turning complex projects into manageable processes and technical specs into commercial returns. For integrators, this means higher margins and customer loyalty; for end users, predictable ROI and user experience. As the product matrix expands with COB fine-pitch, LCD splicing, and conference all-in-one displays, Stonbel will deepen its service network across 31 provinces, driving the industry's shift from hardware sales to full-lifecycle services.
