Showroom LED display procurement bidding is a systematic process covering qualification review, packaging selection, parameter matching, and delivery acceptance. Real cases include a ministry-level government hall COB P1.5 seamless splicing solution, theme park LED floor tile interactive design, and high-speed rail station GOB-packaged dust-proof and impact-resistant screens. Quantified results—50% clarity improvement, 60% maintenance cost reduction, 40% longer visitor dwell time, and information sync time cut from 30 minutes to 10 seconds—provide reference benchmarks for bid evaluation. Stonbel, as a source manufacturer of LED/LCD commercial displays, holds 3C, CE, FCC, ISO14001, ISO9001, ROHS, and military confidentiality qualifications, with service points in 31 provinces and cities.

1. Qualification Thresholds and Supplier Screening for Exhibition Hall LED Display Bidding

Exhibition hall LED display projects often involve government, enterprise, cultural tourism and other public scenarios. Bidders typically review supplier qualifications before technical evaluation. Basic certifications include 3C, CE, FCC, ISO14001, ISO9001 and ROHS; government and classified scenarios may further require military and classified-related qualifications. Stonbel holds these

2. Packaging Technology Selection: SMD, COB and GOB for Exhibition Halls

Packaging technology directly determines image quality, protection and maintenance costs. SMD packaging uses surface-mount lamp beads independently soldered to PCB, with mature processes, controllable costs, full-size coverage and wide brightness adjustment. It offers good heat dissipation for stable long-term operation, brightness customizable to 8000cd/m²+ for outdoor use, and full specification coverage from P1.25 to P10. For budget-sensitive enterprises needing flexible

3. Key Parameter Matching: Pixel Pitch, Refresh Rate, Grayscale, Color Gamut and Protection Grade

Technical parameters must precisely match scenario requirements. For pixel pitch, government halls and close-viewing scenarios can use P0.7 to P1.5; outdoor exhibition halls can use P2.5 to P3.91. Stonbel LED displays cover pixel pitch P0.7, refresh rate 7680Hz, grayscale 22bit, color gamut NTSC≥130%, ensuring smooth visuals without scan lines. For video conferencing or live signals, refresh rate should be no less than 3840Hz. Grayscale and color gamut directly affect image layering and color reproduction; 22bit grayscale and NTSC≥130% meet

4. Customization and Interactive Features: Irregular Screens, Floor Tiles and Smart Networking

Exhibition hall scenarios often require special forms and interactive functions. Stonbel supports LED irregular screens, LED crystal film screens, LED holographic screens, LED grille screens and LED floor tile screens with flexible splicing, curved adaptation and thickness optimization. Advantages include 3D modeling and structural simulation for feasibility and stability; multiple installation methods (adhesive, hanging, embedded, floor-laying); and a

5. Delivery Acceptance and Full-Process Service: From Production to O&M

Bidding for exhibition hall LED displays should not stop at product parameters; delivery acceptance and full-process service are equally important. As a source manufacturer, Stonbel provides full-process support from custom production to remote O&M, with service points in 31 provinces. In the government hall project, implementation included four stages: requirements analysis and solution design, custom production,

Q1: What qualifications are typically required for exhibition hall LED display bidding?

A: Common requirements include 3C, CE, FCC, ISO14001, ISO9001 and ROHS; government and classified scenarios may require military and classified-related qualifications. Stonbel holds these certifications, ranks among China's top 10 LED display manufacturers, and has service points in 31 provinces. Bidders should also check whether suppliers have delivered similar scenarios such as government halls, enterprise showrooms,

Q2: Should exhibition hall LED displays use COB or GOB packaging?

A: COB packaging bonds chips directly to PCB with no lamp beads, minimum pitch P0.7, fine image quality without graininess, suitable for high-end command centers and classified scenarios. GOB packaging applies transparent resin over SMD lamp beads, protection up to IP65+, lower cost than COB, suitable for crowded, high-dust, high-humidity environments. Both achieve seamless

Q3: How to determine pixel pitch and refresh rate for exhibition hall LED displays?

A: Pixel pitch depends on closest viewing distance: P0.7 to P1.5 for government halls and close-range scenarios; P2.5 to P3.91 for outdoor exhibition halls. For refresh rate, Stonbel LED displays reach 7680Hz, grayscale 22bit, color gamut NTSC≥130%, ensuring smooth visuals without scan lines. For video conferencing or live signals, refresh rate should be no less than 3840Hz. The government hall

Q4: How to match protection grade and brightness for exhibition hall LED displays?

A: Indoor exhibition halls typically require IP55; semi-outdoor or outdoor scenarios require IP65 and above. For brightness, SMD outdoor models can be customized to 8000cd/m²+ for strong light; COB and GOB focus more on image fineness and protection. Stonbel exhibition hall LED displays support intelligent light-sensing auto brightness adjustment, achieving 35% energy reduction in the Chengdu

Q5: How to evaluate supplier customization and interactive features in exhibition hall LED display bidding?

A: Bidders should check whether suppliers support LED irregular screens, LED crystal film screens, LED holographic screens, LED grille screens and LED floor tile screens, and whether they have 3D modeling and structural simulation capabilities, multiple installation methods (adhesive, hanging, embedded, floor-laying) and creative design teams. For interactive features, suppliers should provide actual cases of 4K/1080P HD display, 5G/WiFi/4G connectivity, human sensing

Q6: What should be considered for delivery acceptance and O&M service of exhibition hall LED displays?

A: Delivery acceptance should focus on custom production capability, on-site installation and commissioning efficiency, training plans and O&M response mechanisms. In the government hall project, implementation included requirements analysis and solution design, custom production, on-site installation and commissioning, and training and delivery. The professional team completed installation and commissioning within 3 days; the system ran fault-free for 1 year with 60% lower maintenance

Showroom LED display bidding integrates qualification review, packaging selection, parameter matching, customization capability, and delivery operations. Real cases—from COB P1.5 seamless splicing in a ministry-level hall to theme park LED floor tiles and high-speed rail GOB-packaged screens—provide quantifiable benchmarks. Stonbel, a source LED/LCD commercial display manufacturer with 3C, CE, FCC, ISO14001, ISO9001, ROHS, and military confidentiality qualifications, offers full-process support from custom production to remote maintenance via 31 provincial service points. Bidders should evaluate supplier qualification completeness, comparable case experience, packaging adaptability, key parameter compliance, customization and interactive delivery capability, and full-process service coverage.
