Stonbel, a source manufacturer in the LED display industry, specializes in commercial displays with a complete product matrix from P0.7 ultra-fine pitch to P10 standard pitch. This article analyzes key factors affecting per-square-meter pricing, including new upgrades, dimensional comparisons, and selection advice, to help buyers balance budget and performance.

New Launch: Conference Hall LED Displays Enter the COB Era

Stonbel's latest COB fine-pitch LED display uses a lamp-free structure with chips directly bonded to the PCB board and fully encapsulated in adhesive, completely eliminating the grainy texture and physical seams of traditional SMD lamps. The result is a smooth, mirror-like picture. With a minimum pixel pitch of P0.7, the pixel density is over 4 times that of conventional P1.5 products. Even at close viewing distances under 3 meters, text edges remain sharp and image details stay rich, meeting the visual needs of front-row leadership and guest speakers in conference halls. The display features a refresh rate of up to 7680Hz, far exceeding the broadcast-grade 3840Hz standard. Combined with 22-bit grayscale and an ultra-wide color gamut of NTSC≥130%, it delivers smooth color transitions and deep, detailed blacks—whether playing corporate videos with bright highlights or displaying dark charts in academic

Delivery: As a source manufacturer, Stonbel has permanent service points across 31 provinces and cities, enabling rapid site surveys, custom production, and on-site installation. The new products support non-standard module customization, with 3D modeling and structural simulation available for irregular walls, curved steps, and other special structures to ensure the screen fits the architecture seamlessly. Compared to older models that relied on third-party splicing services, the direct-from-factory model shortens delivery cycles by approximately 30% and provides one-stop service from design to training and acceptance. In one case, a 120㎡ COB P1.5 screen for a national ministry's government affairs hall was installed and debugged in just 3 days, demonstrating factory-level delivery efficiency. The Wuhan Optics

Selection Recommendations

Determine the pixel pitch range based on viewing distance and usage frequency. If the first row of the audience is less than 3 meters from the screen and fine data charts or HD video conferencing content will be displayed, COB products below P1.2 are recommended—their grain-free, seamless characteristics significantly enhance viewing comfort. For conference halls with greater depth primarily showing PPTs and promotional videos, SMD or GOB products at P1.8–P2.5 are sufficient and more economical per square meter. For halls that frequently host live-streamed or recorded events, ensure the refresh rate is no lower than 3840Hz—Stonbel products support up to 7680Hz, guaranteeing no scan lines in camera shots. Regarding audio and control system integration, Stonbel's smart interactive and networking features support 4K/1080P HD signal input with built-in 5G/WiFi/4G multi-network access, and can interface with

Q1: How much does a conference hall LED display cost per square meter?

A: The per-square-meter price of a conference hall LED display mainly depends on pixel pitch and packaging technology. Stonbel offers a full range from P0.7 to P10. Among these, P2.5 SMD standard screens are more affordable and suitable for medium-to-large conference halls, typically priced in the thousands of yuan per square meter (depending on configuration). COB products below P1.2 command higher prices due to greater pixel density and enhanced protection, potentially reaching tens of thousands of yuan per square meter. GOB packaging serves as a middle-ground option between SMD and COB, achieving COB-like protection at a cost slightly above SMD—ideal for budget-conscious projects in complex environments. For an exact quote, please contact the Stonbel technical team with CAD drawings or on-site survey data to receive a detailed proposal.

Q2: Should I choose COB or SMD packaging for a conference hall LED display?

A: If the viewing distance is short (under 3 meters) and professional image quality is required—such as in video conference rooms or academic lecture halls—COB packaging is recommended. COB bonds chips directly to the PCB board with full encapsulation, achieving a minimum pitch of P0.7, no graininess, IP65 protection, and no risk of lamp detachment, resulting in extremely low maintenance costs. A national ministry's government affairs hall adopted a 120㎡ COB P1.5 screen for seamless splicing with 4K input, running stably for 1 year with zero failures and a 60% reduction in maintenance costs. If the budget is limited and viewing distance is greater (over 5 meters), SMD packaging covering P1.25–P10 offers mature technology and controlled costs while meeting everyday display needs. The

Q3: What impact do refresh rate and grayscale have on a conference hall LED display?

A: Refresh rate determines whether scan lines appear when the screen is captured by cameras. Stonbel conference hall LED displays feature a refresh rate of up to 7680Hz, far exceeding the standard 3840Hz, ensuring flicker-free, scan-line-free footage during live streams or recordings—particularly important for government and enterprise halls that frequently host online broadcasts or media interviews. Grayscale affects the smoothness of color transitions—22-bit grayscale delivers fine shadow detail and prevents color banding in dark areas. For professional content such as HDR video, medical imaging, or engineering drawings, high grayscale ensures precise detail reproduction, improving viewer comfort and information accuracy. For example, Peking Union Medical College Hospital uses Stonbel high-grayscale displays in its academic lecture hall for surgical demonstrations and pathology image analysis, with color accuracy and depth earning recognition from specialists.

Q4: How can I ensure long-term reliability of a conference hall LED display?

A: Reliability depends on packaging technology and manufacturer quality control. Stonbel's COB packaging fully seals chips with no lamp detachment risk and an IP65 protection rating; GOB packaging adds a resin layer over SMD lamps for similar dust and impact resistance, validated in the high-humidity Zhangjiajie karst cave environment. Products are certified to 3C, CE, FCC, ISO9001, ISO14001, and ROHS standards, and meet military and classified project requirements. Each unit undergoes 72-hour aging testing before shipment to ensure module stability. In terms of service coverage, Stonbel maintains permanent service points across 31 provinces and cities for rapid response—typically reaching the site within 4

Purchasing an LED display for a conference hall involves weighing display quality, initial investment, and long-term maintenance costs. Stonbel provides clear selection paths with full-size coverage from P0.7 COB to P10 SMD, flexible GOB options, and added capabilities like smart interaction and rapid rental-grade deployment. Source-factory direct supply eliminates middleman costs while ensuring local service across 31 provinces. Proven in diverse scenarios, from high-humidity environments to rapid installations, Stonbel recommends early consultation with technical teams to tailor solutions and transparent quotes, ensuring every square meter delivers reliable display value.
