Comparison by Dimension

Different product lines have distinct boundaries for viewing distance and pixel pitch. COB fine-pitch displays cover P0.7-P1.8, 3840Hz, IP55, lifespan ≥100,000 hours, suitable for 2-8m close-range analysis, command dispatch, and industrial environments. In the Changqing Oilfield project, a custom 100㎡ Stonbel P1.5 industrial-grade COB display with high-seal dustproof design adapted to high-dust oilfield conditions, wide temperature range for day-night温差, integrated with production control platform and wellsite monitoring, enabling

Optimization Value

Stonbel's case production and quality control value lies in three aspects: proprietary COB chip-level packaging, factory-direct pricing and profit protection, and full-spec plus special-scenario customization. Proprietary COB chip-level packaging enables integrators to deliver better image quality, longer lifespan, and lower maintenance cost, improving customer satisfaction and repeat purchases, while differentiating with eye-care and high-refresh features. In the Changqing Oilfield project, COB high-seal dustproof design reduced failure rate by 90% and maintenance cost by 62% in high-dust, temperature-varying conditions. In the steel plant project, chip-level dustproof and impact-resistant

Selection Recommendations

In general commercial display scenarios, integrators can select P0.7-P2.5 based on actual viewing distance, comparing protection, refresh rate, and color gamut. For 2-3m close analysis, prioritize P0.7-P1.0, such as the P1.0mm military-grade anti-EMI COB display at the Rocket Force brigade underground command center and the P1.25 ultra-HD military-grade fine-pitch LED screen at Hunan Provincial Military Command, both maintaining detail recognition at close range. For 3-6m mid-close command, P1.2-P1.5 is practical: Changqing Oilfield uses P1.5, steel plant uses P1.2, SF Express HQ uses P1.5, Gree Zhuhai base uses P1.5, all achieving quantifiable

Q1: How do viewing distance and pixel pitch correspond for Stonbel COB fine-pitch displays?

A: There is no single formula, but project experience provides reference. Stonbel's Changqing Oilfield project uses P1.5 at about 4-6m; steel plant uses P1.2 at about 3-5m; Hunan Provincial Military Command uses P1.25 at about 3-5m; Rocket Force brigade uses P1.0mm for 2-3m close analysis; SF Express HQ uses P1.5 with 100㎡ for mid-close command. P0.7-P1.0 suits 2-3m close analysis, P1.2-P1.5 suits 3-6m mid-close command, P1.8-P2.5 suits 5-8m halls or showrooms. Actual selection depends on specific model and project plan.

Q2: What are the protection rating and lifespan of Stonbel COB fine-pitch displays?

A: Stonbel COB fine-pitch displays have IP55 rating, lifespan ≥100,000 hours, 3840Hz refresh rate, and P0.7-P1.8 pixel pitch. In the Rocket Force brigade underground project, MTBF exceeded 110,000 hours with 85% lower core-area maintenance frequency. In the Changqing Oilfield project, high-seal dustproof design adapted to high-dust conditions with wide temperature range, reducing failure rate by 90% and maintenance cost by 62%. In the steel plant project, chip-level dustproof and impact-resistant packaging with high-temperature design

Q3: What actual military and classified projects does Stonbel have?

A: Stonbel has multiple military and classified delivery cases. The Rocket Force brigade underground command center uses P1.0mm military-grade anti-EMI COB display with full metal shielding, GJB 151B EMC certification, national cryptographic encryption, chip-level unexposed packaging blocking signal leakage, front-maintenance modular structure, and remote secure O&M resolving 90% of basic faults remotely. Results: one-time passage of classified security acceptance, zero signal leakage, zero annual standby failures, MTBF exceeding 110,000 hours, 85% lower core-area maintenance frequency. Hunan Provincial Military Command uses 80㎡ COB P1.25 ultra-HD

Q4: What are the differences in pixel pitch and color gamut between Stonbel LCD and LED displays?

A: Stonbel LCD display features P6, NTSC≥120%, IP65, suitable for mid-far viewing in government, business, education, and broadcasting. LED display features P0.7, 7680Hz, 22bit, NTSC≥130%, suitable for high-quality close-range display. COB fine-pitch display features P0.7-P1.8, 3840Hz, IP55, lifespan ≥100,000 hours. LED texture screen features P5, IP54, integrating architectural-grade texture decoration with Micro-LED display. Conference all-in-one features P5, 300-1000cd/㎡, 16bit, NTSC≥110%. Selection should consider viewing distance and signal source resolution, plus protection, refresh rate, and lifespan.

Q5: How does Stonbel's case production and quality control help integrators improve win rates and order values?

A: Stonbel helps integrators through three aspects: full-spec and special-scenario customization, proprietary COB chip-level packaging, and factory-direct pricing with profit protection. Full-spec customization enables one-stop full-scenario display products, expanding into high-end special projects, improving win rates and order values, and avoiding multi-supplier coordination costs. Proprietary COB chip-level packaging delivers better image quality, longer lifespan, and lower maintenance cost, improving customer satisfaction and repeat purchases, while differentiating with eye-care and high-refresh
