​​How to accurately match the procurement needs of LED color screens?​​
Purchasing LED color screens requires key considerations​Space adaptability​、​Display performance parametersandService guarantee system​Three dimensions. It is recommended to choose a model with brightness of 800-1200cd/m² in indoor scenes to ensure that the picture does not turn white in natural light; outdoor fields need to be matched with a high-bright screen body of above 4000cd/m², and paired with IP65 protective structure to resist extreme weather. Supplier should be requested before purchasing72-hour continuous aging test report​, focus on observing color uniformity indicators (within ±5% is the high-quality standard).

​​What technical parameters determine the effectiveness of the screen?​​
• ​​Refresh rate ≥1920Hz​​: Eliminate high-speed screens to meet dynamic scenes such as live broadcasts of sports events
• ​Intelligent brightness adjustment​: Automatic dimming is achieved through ambient light sensor, and the energy saving amplitude is up to 40%.
• ​Box Accuracy​: Choose a model with slit ≤0.1mm to avoid image splitting and affecting the appearance
• ​​Grayscale​: 16bit processing technology can restore 8.6 billion colors, presenting a delicate gradient effect

​​What service capabilities should professional suppliers have?​​
High-quality suppliers need to be built​Full process technical support system​​：

1. ​​Program design stage​: Provide 3D modeling and simulation services to accurately calculate the relationship between screen size and visual range
2. ​​Installation and debugging phase​: Equipped with professional-level calibration equipment to ensure the color difference of the entire screen △E≤2 (the human eye cannot be distinguished)
3. ​​Operation and maintenance guarantee stage​: Establish a 24-hour response mechanism and promise 48-hour arrival service for key spare parts

​​How to select different application scenarios?​​

​​What does a global service network mean?​​
Choose suppliers with experience in project implementation in multiple countries to avoid​Conflict of technical standards​Risk. For example, the humid and heat environment in Southeast Asia needs to be particularly strengthened for moisture-proof treatment, and the Japanese and Korean markets have strict requirements on EMC electromagnetic compatibility. High-quality suppliers should hold international certifications such as CE and CCC, and be able to provide support from local installation teams to shorten the construction cycle by 15%-20%.

The essence of the procurement of LED color screens is the deep coupling of technical solutions and usage scenarios. From the box heat dissipation structure to the signal processing algorithm, every detail affects the cost of use over the five-year period. It is recommended that the purchaser asks the supplier to provide​Three-year warranty commitment​, and through on-site inspections of production bases, verify the quality control strength of enterprises with a monthly production capacity of 10,000 square meters.
