In LED and LCD commercial display, project success depends on the manufacturer's production strength and supply chain mastery. Stonbel's manufacturing system, with five bases in Shenzhen and Huizhou, provides full-scenario displays from COB fine-pitch to LCD video walls. Real cases like China Resources Land, Zhejiang Radio & TV, and national ministries show how in-house manufacturing translates into speed, cost efficiency, and long-term stability—offering quantifiable benchmarks for procurement decisions.

Project Background

Stonbel's in-house manufacturing is backed by concrete production capacity and certifications, not just a slogan. Five production bases cover core product lines including LED displays, LCD video walls, and conference all-in-one machines, with a complete manufacturing chain from PCB SMT and module packaging to final assembly. For COB products, our proprietary chip-level packaging technology enables vertical integration from LED chips to modules, with pixel pitches from P0.7 to P1.8, a refresh rate of 3840Hz, IP55 protection rating, and a design life exceeding 100,000 hours. This in-house model offers integrators unmatched customization flexibility—whether it's irregular-shaped naked-eye 3D screens or non-standard modules for special building structures—all produced on our own lines, compressing typical 15-30 day custom lead times to just 7-10 days.

Delivery Highlights

Another key highlight is the substantial reduction in long-term operating costs. For the Zhejiang Radio and Television Group studio project, Stonbel delivered a 5×5 video wall using 55-inch panels with 0.88mm bezel width. Featuring broadcast-grade A+ LCD panels with per-unit professional color calibration, the wall achieves ≥99.5% brightness and color consistency, covering 120% NTSC gamut. This directly resolved the image splitting and color deviation issues of the previous 3.5mm bezel wall, improving color accuracy by 45%. More critically, the annual failure rate dropped by 92% and maintenance costs by 63%, thanks to industrial-grade dual power redundancy and intelligent thermal control, ensuring 7×24 uninterrupted operation. For broadcast users, Stonbel's in-house manufacturing optimizes not just initial procurement costs but significantly lowers total cost of ownership across the entire equipment lifecycle.

Core Specifications

In the LCD video wall line, Stonbel demonstrates similar specification advantages from in-house production. For a national ministry government service hall project, we deployed a 120㎡ COB P1.5 ultra-fine pitch LED screen supporting 4K input with 3840Hz refresh rate, achieving a seamless display. In the Panzhihua Public Security Bureau project, a combination of COB1.2 and COB1.5 screens enabled simultaneous dispatch of alarm data, surveillance feeds, and GIS maps on one wall, with no visible grain up close and zero-latency multi-signal switching. Our full product matrix also includes innovative offerings like LED texture screens, which merge architectural-grade textures with Micro-LED technology (P5 pitch, IP54 rating), turning the screen into décor when off and a display when on. These specifications are backed by 12 patents, 37 software copyrights, and certifications including 3C, CE, FCC, ISO9001, ISO14001, and ROHS.

Customer Feedback

Feedback from government and overseas clients confirms the core value of in-house manufacturing. A major Hanoi contractor using Stonbel OEM/ODM services cut total procurement costs by ~35%, shortened lead times from 8 weeks (European solutions) to 3 weeks, and completed over 20 projects in Vietnam and neighboring countries in the first year. A municipal emergency command center project achieved citywide centralized display of emergency data and surveillance, improving data detail recognition by 85% and achieving 99.99% availability—under 30 minutes of downtime annually—earning special recognition from the local emergency management bureau. A Chengdu system integrator, leveraging a provincial emergency command center project, grew high-end display revenue share by 32% and cut after-sales labor costs by 30%. These results point to one conclusion: Stonbel's in-house manufacturing—with factory-direct pricing, end-to-end technical support, and localized service networks—is a reliable partner for integrators expanding into the high-end display market.

Q1: What does Stonbel's in-house manufacturing specifically mean?

A: It means Stonbel, as a source manufacturer of LED/LCD commercial displays, operates five production bases (Shenzhen, Huizhou, etc.) with complete in-house capabilities from COB chip-level packaging and SMD conventional LED to LCD video wall assembly. Products go from circuit design and module production to final assembly entirely in our own factories—no external OEM—ensuring stricter quality control, greater customization flexibility, and shorter lead times. For integrators, choosing a source manufacturer means bypassing middlemen to get factory-direct pricing and full technical support.

Q2: What are the core specifications of Stonbel's COB fine-pitch displays?

A: Key specs include pixel pitches from P0.7 to P1.8, 3840Hz refresh rate, IP55 protection rating, and a design life of at least 100,000 hours. These make the displays ideal for close-viewing applications like command centers, control rooms, and high-end meeting rooms, delivering grain-free image quality and flicker-free motion. The IP55 rating ensures stable operation in dusty or humid environments. We also offer custom production in mainstream pitches like P1.2 and P1.5 to match specific resolution and budget requirements.

Q3: What advantages do Stonbel's LCD video walls have over competitors?

A: The core advantages are ultra-narrow bezels and broadcast-grade color. In the Zhejiang Radio and TV project, our 55-inch panels with 0.88mm bezel width, after per-unit calibration, achieved ≥99.5% brightness/color consistency and 120% NTSC gamut, meeting 4K UHD broadcast standards. Compared to common 3.5mm bezel products, the 0.88mm bezel virtually eliminates image splitting, improving color accuracy by 45%. Additionally, industrial-grade dual power redundancy and intelligent thermal control support 7×24 operation, cutting annual failure rates by 92%—ideal for broadcast and emergency command environments.

Q4: How does Stonbel protect integrators' project profit margins?

A: Stonbel protects margins through factory-direct supply. As a source manufacturer with no distribution middlemen, we offer highly competitive ex-factory pricing. For example, a Hanoi contractor cut total procurement costs by ~35% through Stonbel OEM/ODM services. We also provide regional project protection for channel partners to prevent destructive price competition. In the Panzhihua project, the integrator achieved 28% higher profit per project compared to traditional SMD solutions, thanks to our end-to-end bid support and product backing, and subsequently won three additional district-level projects—enabling sustainable profit growth.

From commercial landmarks to government halls, provincial broadcast studios to municipal command centers, Stonbel's manufacturing value is proven. Five bases, COB chip-level packaging, and a 31-province service network form the core advantage. Choosing Stonbel means more than a display supplier—it's a full partner offering customization, design, bidding support, rapid delivery, and lifecycle maintenance. In a competitive market, Stonbel helps integrators overcome resource limits, win high-end projects with lower cost and higher quality, and drive growth.
