As financial services emphasize experience and security, bank branches—the most frequent physical touchpoint—depend on display terminals for clarity, stability, and operational efficiency. LED displays showing rates, announcements, fraud alerts, and branding have become essential. With many suppliers, how to identify a genuine source manufacturer? This article reviews Stonebell's real bank projects, analyzing core data, outcomes, customer value, and future plans, showcasing how a source manufacturer with military-grade DNA uses P0.7-COB and 7680Hz refresh to build reliable, maintainable displays.

Core Project/Product Data

These figures reflect Stonbel's proprietary control over core processes as a source manufacturer. COB packaging directly bonds light-emitting chips to the PCB board and seals them with adhesive, eliminating the physical granularity of traditional SMD lamps. This ensures bank branch LED displays remain fine and grain-free even at close viewing distances. Additionally, the lamp-free structure provides higher protection levels, effectively resisting dust and moisture erosion common in branch environments. Laboratory aging tests show that after 1,000 hours of continuous operation under constant temperature and humidity, brightness decay is less than 1%, with a theoretical lifespan exceeding 100,000 hours. For bank branches requiring 7×24 uninterrupted operation, high reliability translates to lower failure rates and fewer unplanned

Deployment Results

In terms of display performance, the P1.5 fine-pitch screen using COB packaging achieves seamless splicing across the entire display, completely eliminating the physical seams and color deviations of older screens. When showcasing bank brand films or wealth management product ads, colors are accurately reproduced with natural brightness transitions, delivering an immersive visual experience from just 3 meters away. More importantly, system stability has withstood peak business periods. During quarter-end and year-end surges, the screen operated 24/7 with zero downtime, with no service interruptions caused by display failures. At project acceptance, branch managers reported that brightness uniformity (≥97%) and color temperature consistency (within ±500K) far exceeded

Customer Value

The deeper value lies in how high-reliability display systems ensure continuity of banking services. In the financial industry, any information disruption caused by equipment failure can trigger customer dissatisfaction or even regulatory risk. Stonbel provides a dedicated 7×24 maintenance mechanism, backed by permanent service points across all 31 provinces and cities, ensuring that any branch anomaly receives a response within 2 hours and on-site resolution within 4 hours. Additionally, the screens support multiple signal inputs and split-screen display, allowing real-time exchange rates, queue ticketing, and security surveillance footage to be shown simultaneously, enhancing space utilization and operational efficiency. For bank IT departments, unified branding and models of display terminals greatly simplify device management and spare parts

Future Plans

Third, in terms of service models, Stonbel will introduce a "Display as a Service" rental model, suitable for temporary bank events, branch renovation transitions, or pilot new flagship stores. Leveraging rapid deployment capabilities of rental screens (single cabinet weight ≤8kg, 10-second assembly per cabinet), temporary display zones or curved interactive screens can be set up in minimal time to meet the flexible needs of bank marketing activities. Additionally, in response to the trend toward intelligent and experiential bank branches, Stonbel is developing LED texture screens. Their "decorative when off, display when on" feature allows screens to blend into branch interior design, presenting a marble or wood grain texture in standby mode and switching to high-definition information display when needed. This innovation is expected to become a differentiating highlight for premium

Q1: COB or SMD packaging for bank branch LED displays?

A: It depends on the specific installation location and budget. COB packaging bonds chips directly to the PCB board with no lamp structure, delivering grain-free, fine image quality with minimum pixel pitch down to P0.7 and high protection levels—ideal for close-viewing areas like VIP rooms or main lobby screens. SMD packaging offers mature processes and controlled costs, supports all size specifications, and outdoor versions can be customized to brightness above 8000cd/m², suitable for street-facing windows or outdoor signage. Stonbel recommends COB for key indoor areas and SMD for outdoor or high-brightness environments—combining both balances performance and cost.

Q2: What refresh rate is eye-friendly for bank branch LED displays?

A: Higher refresh rates produce more stable images, reducing eye fatigue during prolonged viewing. Stonbel's bank branch LED displays with COB packaging achieve refresh rates up to 3840Hz, while the full series supports up to 7680Hz ultra-high refresh—far exceeding typical camera capture frequencies. This ensures no scan lines or moiré patterns under strong lighting at financial transaction counters, providing comfortable viewing of rate boards or promotional videos. We recommend bank branches choose products with at least 3840Hz refresh to meet 7×24 continuous display requirements.

Q3: What protection rating is needed for bank branch LED displays?

A: Bank branches include both indoor and semi-outdoor areas. For pure indoor lobbies with minimal dust and moisture, IP55 protection is sufficient. However, for open entrance areas or street-facing windows, IP65 or higher is recommended to prevent water and dust ingress. Stonbel's COB packaging products achieve IP55, GOB packaging can reach IP65+, and outdoor versions support brightness customization above 8000cd/m². Specific selection should be based on the actual branch environment, with a solution proposed by our engineers after on-site survey.

Q4: How to identify a reliable bank branch LED display manufacturer and verify source factory status?

A: Three points help verify a source manufacturer: First, certifications—check for 3C, CE, FCC, ISO9001, ISO14001, plus military and classified project qualifications, proving production and quality control capabilities. Second, case history—look for financial sector projects, such as provincial-level Postal Savings Bank deployments. Third, service—confirm permanent service points across all 31 provinces and cities with 7×24 response capability. Stonbel, ranked among China's top 10 LED display companies, operates its own module production lines with full COB/SMD/GOB packaging processes, offering one-stop service from requirements analysis and custom production to installation and maintenance—a reliable choice for bank branch LED displays.

Bank branch LED displays are critical for financial service visualization, impacting customer experience and operations. Stonebell, with source manufacturing, military-grade quality, and nationwide service, has set replicable benchmarks at Postal Savings Bank of China. From P0.7 COB to 7680Hz refresh, IP65 protection, and minute-level remote updates, each metric proves source-level quality and cost control. As branches upgrade, Stonebell will continue delivering clearer, more stable, and smarter display solutions.
