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.

The LED aging test is based on the product's failure rate curve, which is the characteristics of the bathtub curve, and the countermeasures are adopted to improve the reliability of the product.The indoor led module aging method includes constant current aging and constant pressure aging. A constant current source is that the current is constant at any time. The frequency is not constant. That's communication or pulsating current. The communication or pulsating current source can be described as the effective value stable, but this power supply cannot be called "constant current source".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.

The aging of LED display is divided into white balance aging (2x24 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.Check 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.
Make sure the testing time is continuously light for more than 72 hours

After the aging test, please check the quality control group for parameters.Test content: white balance, red, green, blue,gray gradient,video effect,text effect.after 72 hours aging test,the problem should be reported to the manager of the engineering department in a timely manner.replace or repair the broken leds. making sure all parts will be working well stably before packing.
