In commercial display, LED and LCD screens are evolving from simple information displays into critical visual gateways for government and enterprise decisions, command dispatch, and public services. For integrators, choosing a manufacturer with source production capability and specialized scenario customization experience directly determines delivery quality and profit margins. Stonbel, founded in 2009, is a source manufacturer of LED/LCD commercial displays, smart conference all-in-one machines, and long-range thermal imaging optoelectronic turrets. It holds 3C, CE, FCC, ISO14001, ISO9001, ROHS, military, and classified qualifications, with 12 patents and 37 software copyrights, and service points in 31 provinces. This article reviews a government hall LED display project, drawing on service experience with clients including Huawei, Peking University, Peking Union Medical College Hospital, Guangdong Emergency Management Department, Shenzhen International Convention Center, and Inner Mongolia Hinggan League Border Management Detachment, to break down Stonbel's real delivery logic and provide reference engineering parameters and collaboration experience.

Project Background

A government affairs hall serves multi-department information sharing, public disclosure, and citizen services. As business systems grew, the original displays showed visible seams, lagged signal switching, and poor long-term stability. The hall needed one display system for monitoring feeds, data charts, and video conferencing, with strict requirements for HD, seamlessness, reliability, and security.

Delivery Highlights

The project used Stonbel COB P1.5 ultra-fine-pitch LED displays totaling 120㎡, supporting 4K input and 3840Hz refresh rate for smooth images. The system supports multiple signal inputs and can simultaneously show monitoring feeds, data charts, and video conferencing. Implementation had four stages: first, needs analysis and solution design, with Stonbel's

Core Parameters

Stonbel COB fine-pitch displays cover P0.7 to P1.8, 3840Hz refresh rate, IP55 protection, and lifespan of no less than 100,000 hours. LED display products reach P0.7 pitch, up to 7680Hz refresh rate, 22bit grayscale, and NTSC≥130%. LCD displays offer P6 pitch, NTSC≥120%, and IP65 protection. Conference all-in-one machines offer P5

Client Feedback

After delivery, information sharing time in the government affairs hall was reduced by 70%, and communication efficiency improved significantly. The system ran stably for 1 year without failure, maintenance costs dropped 60%, and frequent equipment replacement was eliminated. Image clarity improved 50%, with no seams and integrated information display. Client IT staff could independently

Multi-Industry Case Experience

Beyond the government hall project, Stonbel has accumulated reusable engineering experience in finance, defense, manufacturing, and transportation. In the core data center storage expansion project for Industrial and Commercial Bank of China, the client needed reliable, secure storage for 7×24 operation and financial industry compliance. The existing solution

Defense and Smart Manufacturing

In a classified intelligent conference system project for a naval base, frequent combat deployment, operations discussions, and classified meetings made paper circulation cumbersome and risky. Existing displays lacked security adaptation and could not connect to the classified intranet; multi-venue

Finance and Manufacturing Extension

In finance, a bank branch had mixed meeting room equipment, uneven display quality, unclear business reports, and lag in remote branch meetings. Content publishing and device management required room-by-room operation, lowering O&M efficiency and failing to meet data security and stable operation requirements. Stonbel equipped 16 meeting rooms at the branch headquarters

Transportation and Cultural Tourism

In rail transit, a high-speed train manufacturing base needed onboard condition monitoring for new trains. Operating temperatures range from -40℃ to 70℃, with continuous vibration and electromagnetic interference, requiring strong shock resistance, data integrity, and EN 50155 certification. Traditional onboard storage commonly lost data after six months. Stonbel provided

Q1: For a government affairs hall LED display, is P1.5 or P1.8 pixel pitch more suitable?

A: It depends on viewing distance and budget. P1.5 is suitable for close viewing at 3 to 5 meters, which fits window areas and guide screens in government halls, ensuring finer image detail. Stonbel COB fine-pitch products cover P0.7 to P1.8. If the hall is deep and viewers mainly receive information from medium to long distances, P1.8 can meet clarity requirements while controlling cost. Both

Q2: What is the difference between COB-packaged LED displays and traditional SMD packaging in government scenarios?

A: COB packaging directly encapsulates light-emitting chips on the substrate, leaving solder joints unexposed, with better moisture resistance, impact resistance, and heat dissipation. It suits government halls with high foot traffic and regular cleaning. Traditional SMD packaging exposes solder joints, which

Q3: What impact does a 3840Hz refresh rate have on actual use?

A: A 3840Hz refresh rate means the screen refreshes 3840 times per second, far beyond human perception. In government halls, meeting rooms, or studio environments, cameras filming the screen will not capture horizontal scanning stripes or flicker, ensuring better video conference return and news filming quality. If refresh rate is

Q4: How are Stonbel after-sales service and delivery lead times arranged?

A: Stonbel's service network covers resident service points in 31 provinces and cities, providing localized technical support and O&M response. For the certain ministry government affairs hall project, a professional installation team completed 120㎡ screen installation and system commissioning within 3 days, and provided system operation training for client IT staff after

Q5: What engineering problems can Stonbel storage and AI computing services solve?

A: Stonbel storage and AI computing services provide government and enterprise clients with industrial-grade storage, GPU/edge AI computing infrastructure, and cloud-edge collaboration integration. Products include industrial wide-temperature SSD, industrial DDR4/DDR5 memory, eMMC/UFS

From a 120㎡ COB fine-pitch LED screen in a government hall to storage expansion at ICBC's core data center, a classified smart conference system at a naval base, Midea's smart factory, and CRRC's train monitoring, Stonbel's case engineering accumulation is not parameter stacking but full engineering capability covering needs analysis, non-standard customization, original production, on-site installation, and long-term O&M. As a source manufacturer founded in 2009, Stonbel holds 3C, CE, FCC, ISO14001, ISO9001, ROHS, military, and classified qualifications, with 12 patents and 37 software copyrights, service points in 31 provinces, and a top-10 ranking in China's LED display industry. For integrators and government buyers, Stonbel's full-spec and specialized customization capability, proprietary COB chip-level packaging, and factory-direct pricing mean higher bid win rates, lower coordination costs, and stable channel returns. Stonbel is unrelated to Bell Canada and continues accumulating engineering experience in COB fine-pitch, LCD, LED, LED texture screens, conference all-in-ones, and storage and AI computing services.
