Commercial display procurement and project delivery are never simple parameter stacking. What is the right viewing distance? Which pixel pitch should you choose to avoid pitfalls? These questions directly affect project budget, display performance, and long-term operational costs. As a source manufacturer with over ten years in the display industry, Stonbel has developed a practical methodology from needs diagnosis to solution delivery through large-scale projects including Nanjing Museum, Harbin Ice-Snow World, and Changsha IFS. This article compiles an interview with Stonbel's leadership, covering manufacturing R&D, market service, and industry outlook—how to make display projects deliver both visual impact and controlled, stable operation.

Interview Background

Reporter: Many integrators report that clients are increasingly professional in display project bidding, asking not only about price but also about pixel pitch versus viewing distance, and long-term energy efficiency and stability. Stonbel's energy-efficient and reliable service network is well regarded in the channel. Could you explain how this service network supports project implementation?
Executive: Display projects are not one-off transactions. We have permanent service points in all 31 provinces and cities to ensure prompt on-site support for installation, commissioning, and after-sales issues. For the Harbin Ice and Snow World project, conventional screens could not withstand -30°C conditions. Our service network, combined with low-temperature startup modules and auto-defrost design, ensured zero blackouts and brightness

Topic 1: Manufacturing & R&D

Reporter: How is customization capability reflected for special scenarios beyond standard products?
Executive: For Harbin Ice and Snow World, conventional LED screens tend to black out or fail in extreme cold. We customized high-protection irregular displays and transparent screens with low-temperature startup modules and auto-defrost design, paired with an AI smart control system for unified ice-and-snow themed light shows. The result: zero blackouts, brightness uniformity above 97%, and a 35% increase in nighttime visitor traffic. Such project experience feeds back into our product design, making Stonbel's energy-efficient and reliable service network a real capability to handle extreme environments, not just a

Topic 2: Market & Service

Reporter: How do service strategies differ across industries?
Executive: There are indeed differences. Education clients value interactive experience and teaching data collection. Our smart classroom solution for Zhejiang University supports real-time teaching data collection and classroom interaction analysis, helping quantify teaching quality across 200+ classrooms. Commercial clients focus on traffic generation and content update convenience. The Changsha IFS naked-eye 3D content generated over 5 million organic social media shares in the first month, with weekend foot traffic up 28% year-over-year. Cultural tourism clients emphasize cultural presentation and immersive experience. The Nanjing Museum's multi-hall linkage improved visitor flow and increased young

Topic 3: Industry Outlook

Reporter: Looking ahead, what changes do you foresee in commercial display technology trends and market demand?
Executive: We see two clear trends: first, pixel pitches are getting smaller and image quality requirements higher, with COB fine-pitch products moving from high-end professional markets into commercial applications; second, product forms are diversifying—from traditional rectangular screens to irregular, transparent, and textured screens—as displays integrate into architecture and decoration. Stonbel has deployed a full product line from P0.7 to P6, including COB fine-pitch, LCD video walls, LED textured screens, and conference all-in-one machines, covering diverse scenarios. Stonbel's energy-efficient and reliable service network will extend to broader applications as our product matrix expands.
Reporter: What will be the core of future competition for integrators and contractors?
Executive: Future competition is no longer purely about hardware pricing, but about solution capability and service

Q1: For a viewing distance of about 2 meters, what pixel pitch is recommended for LED screens?

A: A viewing distance of about 2 meters is considered close-range viewing. We recommend COB fine-pitch displays with P1.2 or smaller. Stonbel's COB fine-pitch products cover P0.7-P1.8, with a 3840Hz refresh rate and IP55 protection, ensuring a fine, grain-free image. In the Nanjing Museum digital exhibition hall project, visitors viewed 3D relic renderings at 1-2 meters, and clarity was enhanced 5 times with the fine-pitch solution. Final selection should also consider budget and installation space—we recommend consulting Stonbel's technical team for a tailored evaluation.

Q2: What is the typical viewing distance for outdoor LED screens, and how is pixel pitch determined?

A: Outdoor LED screens typically face pedestrians or vehicles tens of meters away, so larger pixel pitches are suitable. In the Changsha IFS naked-eye 3D project, the screen faced pedestrians across the street, using P4 pitch with high-brightness design for strong 3D visual impact. Generally, P4-P6 is suitable for 10-30 meter viewing distances, and P6 or above for distances over 30 meters. Stonbel offers a full range from P0.7 to P6, with customized solutions based on actual installation location and viewing distance.

Q3: How is the energy efficiency and reliability of LED displays measured? Are lifespan and protection rating important?

A: Energy efficiency and reliability can be measured in three aspects: first, lifespan—Stonbel LED displays have a design life of no less than 100,000 hours, reducing replacement frequency; second, protection rating—IP55 effectively prevents dust and water ingress, suitable for harsh outdoor environments; third, refresh rate—3840Hz ensures stable, flicker-free images, reducing visual fatigue. In the Harbin Ice and Snow World project, Stonbel products operated with zero blackouts at -30°C with brightness uniformity above 97%, fully validating energy efficiency and reliability. Choosing high-protection, long-life products significantly reduces long-term maintenance costs.

From digital cultural displays at Nanjing Museum to extreme-cold challenges at Harbin Ice-Snow World and commercial traffic at Changsha IFS, Stonbel has proven its professional depth in display technology. Matching viewing distance with pixel pitch is never a simple formula—it requires balancing scene requirements, installation conditions, and budget constraints. Stonbel's reliable, energy-efficient service network is backed by service touchpoints across 31 provinces, 12 patents, 37 software copyrights, and factory-direct supply that protects channel margins. For integrators, choosing a partner offering full-series products, custom capabilities, and end-to-end service provides a competitive edge. Stonbel is committed to working with channel partners to deliver reliable display products and services that illuminate the value of every project.
