LED Display Module Aging & Testing
LED Display Module aging and testing is refers to imitate the long time operation without working problems,it is the most important to ensure the reliability of the LED display. LED display can be more stable after aging, and it can help the use of the efficiency. led screen aging test is a very important link in quality control.
Constant current aging is the most consistent feature of LED current operation and is the most scientific method for the aging of LED displays. Over current impact aging and manufacturers the latest clothing design school chooses an aging technique, after using the frequency adjustable, current adjustable constant current source for such aging, in order to judging the quality of the outdoor led module in a short time and can pick out the dangerous LEDs make sure the led display module working well after installation.Constant current aging is the most consistent feature of LED current operation and is the most scientific method for the aging of LED displays.

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:
- Check the led display module to install all correct.
- Check whether there is a short circuit or not.
- Check whether the module is flat and neat.
- Check whether the appearance is intact or not.
- Use the online led control system to light up.
Make sure the testing time is continuously light for more than 72 hours
