How to choose a display screen that suits the scene?

​​Core parameters determine the display effect​ ​: When purchasing LED outdoor rolling display screens, you need to focus on checking three technical indicators:

• ​​Brightness adjustment ability​ ​: The outdoor environment needs to have a dynamic adjustment range of 4000-7500cd/m² to cope with changes in day and night light.
• ​​Refresh rate standard​ ​: The high refresh rate of ≥1920Hz ensures no smearing in high-speed images, and clear display in areas with dense traffic flow.
• ​​Protection level verification​ ​: IP65 and above certification is the baseline for waterproofing and dustproofing. In typhoon-prone areas, it is recommended to choose reinforced structural design.

What are the hidden thresholds for supplier screening?

​​Production system and quality certification are hard power​​：

1. ​​Large-scale production capacity​ ​: An automated base with a monthly production capacity of over 10,000 square meters, which can ensure emergency orders are delivered within 7 days
2. ​​Whole process quality inspection system​ ​: 23 inspection processes from patch accuracy to module aging, equipment startup failure rate must be <0.3%
3. ​​International authoritative certification​ ​: CE/CCC certification is the foundation, and manufacturers with film and television-level color calibration capabilities are more worthy of attention.

How to ensure long-term stable operation?

​​Technical support and service network are indispensable​​：

• ​​Low brightness and high gray technology​ ​: It can still achieve 16-bit grayscale at 30% brightness, ensuring the layering of advertising images during the early morning hours.
• ​​Intelligent temperature control system​ ​: - 30℃ to 55℃ environment adaptive heat dissipation, continuous operation for 3000 hours without attenuation in the hot and humid climate of Southeast Asia
• ​​Localization service network​ ​: Choose suppliers with technical response centers in target markets such as Japan, South Korea, and Southeast Asia, and resolve faults on-site within 48 hours.

What procurement experiences do successful cases reveal?

From curved advertising screens in Singapore to Tokyo stadium projects, projects that have been implemented for more than three years have proven:
​​structural design​ ​: The wind pressure resistance of the die-cast aluminum box must reach 12KPa, and salt spray protective coating must be specially added in coastal areas.
​​Content adaptation​ ​: Support HDR10+ format decoding, commercial area advertising screens should match 4K/60fps video input
​​Operation and maintenance costs​ ​: Modular design makes the replacement time of a single box less than 3 minutes, reducing later maintenance costs.

Purchasing decisions should focus on the supplier’s​ ​Project implementation case library​ ​and​ ​Full cycle technology responsiveness​ ​, truly realizing the outdoor display effect of "installation and use, worry-free operation".
