LED display aging test is an important step to ensure the stability and reliability of the product. The following are the general steps for LED display aging testing:
1. Appearance inspection:
- Check whether the appearance of the LED display is intact and whether there are any bumps, scratches or other physical damage.
2. Prepare the test environment:
- Ensure that the test environment has constant voltage, current, and constant temperature and humidity conditions.
- During the test process, it may be necessary to add interference sources and corresponding filters to simulate interference in the real environment.
3. Light up aging:
- Use an online control system to light up the LED display and ensure continuous lighting for more than 72 hours.
- During this period, the display screen should show different contents, such as white screen, red, green, blue monochrome, grayscale gradient, video effect, text effect, etc.
- The testing time for each type of content should be no less than 24 hours.
4. Indicator inspection:
- After the aging test is completed, the quality inspection team will conduct parameter index testing.
- Test items include but are not limited to brightness test, color temperature test, color uniformity test, image saturation test, display consistency test, color rendering index test, etc.
5. Test report:
- Write a test report based on the test results. The report should include detailed information such as test items, test results, test environment, test time, etc.
- The conclusion of the report should be clear and unambiguous to help users understand the performance and expected life of the LED display.
6. Things to note:
- The LED display aging test must be attended by someone so that problems can be discovered and reported for processing in a timely manner.
- Different LED displays may have different aging test methods and standards. In actual operation, the test should be carried out according to the product instructions or relevant standards.
In addition, for the aging test of LED displays, you can also refer to relevant domestic and foreign standards and specifications, such as international UL, CE, EN, IEC and other standards, as well as domestic GB/T, GB/IEC, GBT, GBZ and other standards. , to ensure the scientificity and validity of the test.
In general, the aging test of LED displays is a comprehensive process that requires comprehensive consideration of multiple factors and environmental conditions to ensure product quality and reliability.
