The high-temperature aging time for LCD modules is typically 72-1000 hours, with actual values fluctuating significantly depending on the test type and environment.
1. High-Temperature Aging Time Range
The standard high-temperature aging time setting range is 0.01 - 999.99 hours. Specific adjustments need to be made based on module characteristics and test standards.
2. Duration Corresponding to Different Test Objectives
2.1 LED Module Working Life Test
Ambient Temperature: 85±2℃
Base Duration: 1000 hours, primarily verifying material stability and light decay under long-term high-temperature conditions.
2.2 LED Display Aging Test
· White Screen Test: Continuous illumination ≥24 hours, checking brightness uniformity.
· Monochrome/Grayscale Gradient Test: Continuous operation ≥24 hours, verifying color reproduction capability.
· Dynamic Effect Test: Video/text carousel must meet ≥24 hours, with a total continuous operation time typically required to be 72 hours.
After understanding the basic parameters, let's look at the differences in testing in practical applications: industrial-grade products generally use a 1000-hour extreme test, while consumer-grade products are usually compressed to a 72-hour comprehensive test. It is recommended that specific projects refer to the "SJ/T 11141-2017 General Specification for Light Emitting Diode (LED) Displays" to select the testing scheme.
