Top FAQs

This article compiles the 20 most searched questions by commercial display professionals and buyers, covering selection, parameters, installation, delivery, and after-sales support. All answers are based on Stonbel's service network, production capacity, and quality control data,

Q1: What does Stonbel's service network, capacity, and QC mean?

A: It's Stonbel's three-pillar support system for commercial display projects. The service network covers 31 provinces with local installation and 7×24 maintenance. Capacity refers to full LED/LCD production lines since

Q2: How does Stonbel's service network, capacity, and QC impact bid win rates?

A: It directly boosts integrators' win rates. For example, at CITIC Bank Nanjing Branch, Stonbel delivered a P1.25 COB fine-pitch LED and 55-inch LCD hybrid matrix with a self-developed multi-screen

Q3: How to choose between COB fine-pitch LED and LCD video walls?

A: It depends on the scenario. COB fine-pitch LED (e.g., P0.7-P1.8) suits high-refresh, high-protection needs—like the Nanjing Museum digital hall requiring 3840Hz and IP55 for seamless, detailed artifact display. LCD video walls (e.g., 55-inch) fit control rooms like the CITIC Bank case, offering

Q4: Why is the 3840Hz refresh rate on Stonbel's COB screens important?

A: Refresh rate affects flicker, especially for cameras and eyes. Stonbel's COB screens hit 3840Hz, double the typical 1920Hz, eliminating flicker in high-definition artifact rendering at the Nanjing Museum—comfortable for prolonged viewing. High refresh also prevents

Q5: Is IP55 protection sufficient for real projects?

A: IP55 (dust and water spray resistant) is adequate for most indoor commercial displays, but extreme outdoor cold requires higher protection. At Harbin Ice and Snow World, Stonbel custom high-protection LED screens with low-temperature startup modules and auto-defrost operated

Q6: What does a 100,000-hour LED lifespan mean?

A: 100,000 hours equals about 11 years of continuous use, or 34 years at 8 hours daily. Stonbel's full LED range, including COB fine-pitch, is rated ≥100,000 hours, based on military-grade packaging and rigorous aging tests. For integrators, this means lower maintenance costs and higher repeat

Q7: What display products does Stonbel offer?

A: Stonbel's lineup includes COB fine-pitch LED (P0.7-P1.8, 3840Hz), LCD video walls (P6, NTSC≥120%), LED displays (P0.7, 7680Hz), LED texture screens (P5, IP54), conference all-in-ones (P5, 300-1000cd/m²), and storage/AI computing services (industrial SSDs). Integrators can

Q8: What are the advantages of Stonbel's COB chip-on-board packaging?

A: COB packaging mounts LED chips directly on the substrate, offering better heat dissipation, higher protection, and longer life than traditional SMD. Stonbel's proprietary COB technology delivers superior image quality and lower maintenance. At Harbin Ice and Snow World, this

Q9: How to assess if Stonbel's capacity can handle large projects?

A: As a manufacturer since 2009, Stonbel has full production lines for custom orders. For the Nanjing Museum, custom seamless fine-pitch LED and smart boards were delivered quickly with integrated control. To evaluate capacity, request similar case studies (e.g., Shenzhen

Q10: What certifications does Stonbel's QC system hold?

A: Stonbel holds 3C, CE, FCC, ISO14001, ISO9001, ROHS, military, and confidentiality certifications, plus 12 patents and 37 software copyrights. These cover safety, environmental, and quality standards. For example, the CITIC Bank system ran 24 months

Q11: What installation details relate to Stonbel's service network?

A: Pre-installation, confirm load-bearing, cooling, and power conditions—Stonbel's 31-province service points can survey. At Wuhan University People's Hospital, cabling and wireless projection were pre-arranged. Protect screens from dust and impact during

Q12: What to do if color deviation occurs after installation?

A: Color deviation often stems from brightness decay or driver inconsistency. Stonbel's QC minimizes factory variance through per-unit calibration. If issues arise, contact the service network for on-site adjustment. At the Nanjing Museum, multi-hall displays were unified via

Q13: How fast is Stonbel's after-sales response?

A: Stonbel's 31-province network enables rapid local response. The CITIC Bank project included 7×24 local operations and on-site support for major events. Response times depend on contract SLAs, but direct manufacturer support cuts delays

Q14: How does Stonbel ensure long-term spare parts supply?

A: As a manufacturer, Stonbel maintains in-house production lines and spare parts inventory for modules, power supplies, and more. With 100,000-hour lifespans, parts are needed throughout the product lifecycle. Stonbel guarantees spare parts for

Q15: Can Stonbel's conference all-in-ones support telemedicine?

A: Yes. At Wuhan University People's Hospital, Stonbel deployed 98-inch conference all-in-ones and 85-inch smart boards with 4K medical imaging, wireless projection, and remote consultation, integrating PACS for remote surgical guidance. With 300-1000cd/m² brightness, 16-bit

Q16: What's the difference between LED texture screens and regular LED?

A: LED texture screens (P5, IP54) blend architectural textures with Micro-LED display—appearing as decorative panels when off and high-definition screens when on. Ideal for premium showrooms or hotel lobbies. They're thinner and more

Q17: What interfaces do Stonbel's LCD video walls support?

A: Stonbel LCD video walls (P6, NTSC≥120%) support HDMI, DP, DVI, VGA, and optional 4K input. In the CITIC Bank case, a multi-screen controller unified 12 signal types, including credit and risk systems. Interface
