Why is it necessary to conduct LED display testing?

​​Q: How do ordinary users judge whether the LED display screen meets the standards? ​ ​
A: Third-party testing is a key step in verifying equipment performance. ​ ​core indicators​ ​include:

• ​​Brightness uniformity​ ​: Outdoor screens need to achieve 4000-7500cd/m² brightness and deviation ≤5%
• ​​Grayscale expression​ ​: Products using low brightness and high gray technology need to achieve 16bit color depth
• ​​Protection level​ ​: Outdoor scenes must pass IP65 waterproof and dustproof test
• ​​Signal stability​ ​: Refresh rate ≥1920Hz can eliminate shooting flicker

The core evaluation criteria of professional testing institutions

​​Q: What qualifications represent the authority of the testing agency? ​ ​
A: When choosing an institution, focus on three points:

1. ​​Certification qualification​ ​: Have CNAS laboratory accreditation or ILAC international mutual recognition qualifications
2. ​​Testing equipment​ ​: Equipped with professional instruments such as goniophotometer and environmental test chamber
3. ​​Service network​ ​:Support multi-national testing standards (such as CE, CCC, JIS)

Full analysis of the detection process

​​A typical inspection process consists of four stages​​：

1. ​​Material verification​ ​: Batch consistency testing of lamp beads and driver ICs (taking 2-3 days)
2. ​​Performance testing​ ​: 72-hour continuous operation aging test + temperature rise curve monitoring
3. ​​Scenario simulation​ ​: Tested in an environmental chamber from -30°C to 60°C to show stability
4. ​​Certification declaration​ ​: Synchronously prepare technical documents and test reports

How to choose cost-effective testing services?

​​Laboratory testing vs on-site testing comparison​​：

For export products, it is recommended to choose​ ​One-stop service supporting multi-country certification​ ​. For example, displays sold to Japan and South Korea must simultaneously meet PSE certification and KC certification requirements.

LED display testing is not only related to the life of the equipment, but also directly affects the operational safety of commercial scenarios. Choose to cooperate with technology-based enterprises that are deeply involved in the display field.​ ​Whole process quality inspection system​ ​and​ ​Localized service network​ ​It can significantly reduce testing costs. Actual measurement data shows that testing services provided by professional organizations can reduce product failure rates by 67%.
