Government & Police Benchmark Delivery | Stonbel Completes Panzhihua Public Security Bureau COB Fine-Pitch Screen Project
In 2026, Stonbel fully delivered the visualized large screen system for Panzhihua Public Security Bureau Command Center, covering supply, installation, commissioning and acceptance. The project adopts self-developed P1.2 D-COB fine-pitch display, paired with self-made control hosts, signal processors and thermal imaging cameras to build a 24/7 integrated police dispatch & analysis platform. As a full-category LED/LCD manufacturer, Stonbel built a smart policing benchmark for southwest Sichuan via self-production, fast customization, police-grade security and localized full-cycle maintenance, strengthening its edge in security display.
1. Project Background & Core Pain Points
The command center oversees public security, emergency response, traffic control, mountain fire patrol and major security coordination, handling 110 alarms and cross-department dispatch. Four strict requirements were set for suppliers:
24/7 Heavy-Duty Stability
Round-the-clock operation causes dead pixels, dark spots and brightness decay in ordinary SMD screens, risking delayed emergency response. Displays need 100,000-hour lifespan, low attenuation, impact, dust and moisture resistance.
High Clarity Under Strong Light
Large windows bring harsh daylight glare to regular screens, blurring surveillance, facial capture and thermal fire images and hindering police judgment.
Multi-Signal Compatibility & Strict Intranet Security
The system must connect dozens of signal sources yet comply with Class-3 Cybersecurity Protection: offline local deployment, end-to-end encrypted data, no external network or third-party backend access.
Tight Schedule & Rapid Local After-Sales
As a key smart policing upgrade, it demanded fast delivery and zero-fault service with in-Sichuan on-site teams (no outsourced maintenance).
Most integrators only assemble outsourced screens with delayed delivery and poor compatibility; top brands charge high customization fees. After technical reviews, factory audits, 72-hour stress testing and security verification, the bureau selected Stonbel for its in-house COB production, self-developed thermal imaging/control systems and full Sichuan service coverage.
2. Stonbel Custom Police-Grade Total Solution
All hardware is independently developed and manufactured with no outsourced parts, tailored across screen structure, frame, signal matching, secure software and installation:
P1.2 D-COB Fine-Pitch Main Screen
Upgraded D-COB modules deliver 20000:1 contrast, 125% NTSC gamut and IP54 protection. Anti-glare coating eliminates daylight reflection. Even heat dissipation, impact resistance and <8% brightness decay over 100,000 hours suit nonstop policing use. Micron-level seamless splicing (<0.05mm error) ensures uniform, crisp surveillance visuals at all viewing distances.
Self-Made Supporting Hardware & Secure Local Software
In-house distributed control hosts, 4K zero-latency switchers, stabilized power supplies and cooling modules pair with self-produced thermal imaging cameras for mountain, river and industrial zone fire/intrusion monitoring, enabling one-click alert dispatch. Offline localized software meets police cybersecurity standards, supporting split screens, roaming, emergency preset plans and patrol rotation with easy operation.
Lightweight Building Adaptation
Engineers surveyed the hall three times to design light steel-aluminum wall frames reducing wall load, shielded separated strong/weak current wiring to avoid signal interference, and reserved expansion slots for future screen and signal upgrades.
3. Full In-House Delivery Assurance (No Subcontracting)
From drawing design and production to installation, calibration, training and acceptance, Stonbel’s full-time internal team managed every stage:
Fast Production: Two 10,000-class dust-free COB workshops cut manufacturing time by 20%. AI inspection and 72-hour full-load aging tests guarantee zero defective shipments.
Certified On-Site Construction: Qualified police project engineers finished screen assembly, wiring and system debugging in 10 days, passing third-party optical, electrical and cybersecurity checks at first attempt.
Precise Calibration & Drill Validation: Fine-tuned white balance, color temperature and brightness for uniform visuals. Three full emergency drills (mountain fires, traffic accidents, mass security, multi-unit 110 response) achieved <0.02s signal switching with no blackouts or freezes.
4. Operational Outcomes & Client Feedback
After two months of operation, the system ran fault-free with stable brightness and smooth multi-signal dispatch. The bureau’s director praised Stonbel’s all-in-one self-developed hardware/software eliminating multi-supplier coordination issues. Key benefits:
40% Faster Cross-Department Dispatch: Unified multi-platform data cuts coordination time and speeds emergency response.
Lower Long-Term O&M Costs: COB’s far lower failure rate reduces part replacements; stocked Sichuan parts cut maintenance downtime.
Full Security Compliance: Offline software, shielded wiring and high-protection screens passed police network, equipment and venue security audits.
5. Stonbel’s Core Competitive Advantages
This benchmark highlights three irreplaceable strengths fueling its top-10 domestic LED display ranking for a decade:
Full Self-Supply Supply Chain
Few firms mass-produce COB screens, LCD commercial displays, thermal imaging cameras and smart control systems in-house, enabling turnkey complex government/police projects with seamless device linkage.
Mature Large-Scale COB Production
Six years of D-COB refinement at 2020-built dust-free workshops delivers 99.8% yield, supporting both large municipal command halls and small substation analysis rooms via mass & flexible custom production.
Regional Government Exclusive Service Network
Nationwide service branches with a dedicated Sichuan team offer 24/7 police emergency hotlines, 2-hour remote support and 24-hour in-province on-site repairs, plus long-term annual maintenance contracts for 10-year stable operation.
Identical COB smart dispatch solutions have launched hundreds of benchmarks across Sichuan, Yunnan, Guizhou for police, emergency, transport and energy sectors with replicable standardized visualization systems.
6. 2026 Corporate Strategic Layout
2026 advances dual-track B2B government deepening + B2C civil expansion:
Government Track: Expand police, emergency, government, energy and transport markets; develop ultra-fine pitch P0.7+ COB for national key security projects.
Civil Track: Adapt display tech into LED texture photoelectric building materials for commercial decor and home renovation.
Manufacturing: Upgrade five national intelligent production bases to hit 50,000 sq.m. monthly LED output. Boost R&D on MiP packaging, low-power screens and AI police analysis algorithms to narrow gaps with global premium brands, building a top domestic smart security display brand.
Market Expansion: Roll out Panzhihua-style benchmarks nationwide at provincial/municipal/county levels; export proven police dispatch packages to Southeast Asia and the Middle East.
