LED Display Module Aging & Testing

The aging test of the LED module refers to running the LED module for a long time to simulate actual use conditions to detect its performance and stability.

Typically, LED modules are run continuously for hours or days, or even longer. So that to ensure that the performance and brightness of the LEDs do not degrade after prolonged use.

During the aging test, we monitor the brightness, color fidelity, uniformity, and other parameters of the LED, evaluating the quality and reliability of the LED module based on the test results.

The aging of LED display is divided into white balance aging (2×24 hours) and video aging (24 hours). Totally 72 hours before packing.

Aging test process of led display screen:

1) Check the led display module to install all correct.

2) whether there is a short circuit or not.

3) Check whether the module is flat and neat.

4) Check whether the appearance is intact or not.

5) Use the online led control system to light up.

After the aging test,, we conduct parameter inspections in the quality control group, including white balance, red, green, blue, grayscale gradient, video effects and text effects, etc.
After 72 hours of aging testing, we will promptly report any problems and contact the engineering department, then to replace or repair the damaged LEDs.
Before packaging, we ensure that all components can operate stably to ensure product quality and reliability.
